what&#39;s up uh welcome back this is a live stream it&#39;s just going to be pretty chill i&#39;ve got some work we want to do on some open source projects and uh yeah i just wanted to share it with you all so if you are hanging around and you want to comment chat uh visit whatever i&#39;m i would love that would love uh to have your company as we hang out so there&#39;s a couple different projects i wanted to maybe work on so inside of stripe samples we have this accept a payment sample and there&#39;s a really cool new payment element that i&#39;ve sort of started a little bit of work on but yeah i would love to just keep hacking on it and talking through as i go so payment element if you haven&#39;t seen it it&#39;s a new sort of drop-in ui component that you can use for lots of different payment method types and uh what we&#39;re doing here is we&#39;re just going to like write out some basic clients and then some basic uh javascript and um on the front end maybe also wire up react with create react app and then we&#39;ve got servers in a bunch of different languages so dot net go java node node with typescript php python and ruby and so we&#39;ll kind of like go through all of those different servers and make sure that they are all creating payment intents with the stripe api and responding with those so i guess the first thing to do would be just kind of show you what we&#39;ve got going on except for payment so you can you can install this from the stripe cli by saying just stripe samples create accept a payment right now it only has the custom payment flow with the older stripe elements we have individual elements for all the payment methods and it has the pre-built checkout page what we&#39;re working on is this brand new payment element version where we can jump into maybe we&#39;ll jump into ruby and say bundle install and then we can run it so igor is asking where will you continue the clear bnb series i know i have been slacking super hard i got like my goal was to to put up three videos per week for the year and then i got super burnt out and uh everything got just super busy life got busy and it ran away from me but um yeah i&#39;m excited to get back into it and play around with it more uh and uh yeah keep keep working on on clear bnb for sure is that series helpful are you guys there certain features that you&#39;re you&#39;re looking forward to seeing up next igor um all right so we&#39;ll fire up the ruby server oh yeah so this is igor saying hey when are we going to work on that clear bnb thing so we&#39;ve got a i&#39;ve got a separate series that i&#39;ve been working on building out um sort of a vacation rental platform with ruby on rails um all right super cool so this is kind of what the payment element looks like it&#39;s this whole entire drop-in thing so like if we look at the html here all we have inside of the html is this div for the payment element and then below that we&#39;ve got the button so like that div for the payment element contains all this stuff for working with the payment element and if we want to we can enter in some credit card some test credit card number and then a zip code and hit submit and then we have a succeeded payment so we can just check it out oh thanks igor really appreciate that um yeah we&#39;d love to we&#39;d love to cover more stuff if you&#39;re if you&#39;ve got specific things that you want to you want to see yeah i would love to would love to make some content for you um and yeah like whatever you think would be helpful right like i want the content to be useful so you can actually go and build stuff so um all right so it&#39;s working in ruby so that&#39;s great and then i also wrote a little r spec here so the spec is called payment element server spec so once the server is starting the way this works is it just kind of like makes requests and pokes at the server to assert that like certain responses come back so ruby is working well let&#39;s jump back up into maybe into node node server so we&#39;ll start that up and then we&#39;ll run our tests and that looks like it&#39;s working well we&#39;ll jump up to node type script and then i can&#39;t remember what the start command is for typescript uh oh it&#39;s just node start again okay node start or npm start npm start npm run start npm start something like that um hey what&#39;s up super rails yarrow um we&#39;re we&#39;re just hacking on some we&#39;re hacking on some stripe samples so we&#39;re working on updating some of our open source examples to use the new payment element so uh yeah that&#39;s what we&#39;re kind of we&#39;re kind of working on today um yeah so yeah i would love for you to stick around this is not using stripe checkout this is using sort of a the uh hosted or sorry the uh the built-in payment element so um we&#39;re in the middle of updating something so you can&#39;t see it now but you&#39;ll see it in a sec uh okay so if we go so typescript no typescript has not been updated yet so we jump into the source in the server here under create a payment intent we&#39;re no longer accepting the currency or payment method type from the front end we used to do that for the individual sample we also did this thing for um or acs debit but we don&#39;t need to do that anymore and so instead what we can do is we can just pass in params here instead of payment method types we&#39;re saying automatic payment methods and then we can say enabled uh true um and yeah you are the the new payment element super cool um so yeah let me get this up and running and i&#39;ll give you a quick peek at it uh you are this is the parameters that we&#39;re going to pass to the api to create a payment intent the payment intent is going to come back and we&#39;re going to render its client secret back to the front end this actually becomes a get request now um and yeah so let&#39;s restart our node server and refresh this we&#39;re also going through each of the server languages and updating them to use the new um payment intent create stuff so oh automatic payment methods does not exist in payment intent create programs cool so this is because the version of stripe node uh that we have installed here is not it&#39;s probably not latest so let&#39;s go check that out so go uh let&#39;s see no no so github.com stripe stripe node just to make sure that we&#39;ve got like the most up-to-date version so version 891 huh 891 0 that should have it huh so let&#39;s see um inside of the stripe node library let&#39;s go to the create or the types i guess for um for my version oh you know what yeah no no this should totally be fine so then payment intent payment okay what&#39;s what&#39;s the deal here so inside of our server.ts we&#39;ve got payment intent create params so we need to look for that params type in here payment intent create params okay um here we go um yeah automatic payment methods here i guess okay so i guess it&#39;s got to be a an instance of that uh so what is this um one of these i think something like this i don&#39;t use typescript very much but we&#39;re going to get this going npm start um hey pierre yeah totally so the payment element um why don&#39;t i why don&#39;t i stop yeah let me uh let me stop the um the node one and go back to ruby for a sec so i can show you what i&#39;m talking about um so usually or like if you&#39;re if you&#39;re familiar with stripe elements then you may have seen sort of like a card input element before the payment element is this entire thing now so card bank contact eps like you can control which payment method types show here based on what you see in the dashboard so if we jump over to the stripe dashboard let me pull that up here so like right now if i go to my settings and i go to payment methods um for euros uh i have enabled well okay so for bank redirect type payment methods i&#39;ve been able to couple but shiropay ideal p24 these all work with euros so like if we look at this payment element right now i&#39;m accepting card bank contact and eps i&#39;m not going to change any code but all i have to do is just say turn this on for shiro pay and now i can come back over to this page and just refresh and i should have now shiro pay as an option so that customers can pay with zero pay so the payment element is a drop in element that&#39;s not hosted by stripe that is just like something that you can use as part of stripe.js for accepting payment so that&#39;s this whole entire thing that has all of these different payment methods that&#39;s what uh that&#39;s what the payment element is so really cool stuff um okay let me jump back over to uh node type script and let&#39;s try to get typescript working so um node i guess like we want to jump into npm run start i think npm start something like that okay so if we come back over here this is failing because um can&#39;t find the name payment intent all right so um um okay oh you know what it is okay so this this uh payment intent this here needs to be namespaced under stripe i think let&#39;s see if that gives us our correct sort of type all right at least it started sort of maybe it started uh crashed again okay uh type amount number currency string automatic payment methods is not assignable to payment intent create params object literal may only specify okay so um i&#39;m wondering if like stripe oh you know what i want to see is like um in the package lock at stripe or stripe i node to make sure that the version yeah okay it&#39;s the right version totally okay um it should have should have support for that i didn&#39;t think that i needed to specify the types like this either like i thought i could just say enabled true but maybe maybe that&#39;s wrong automatic payment methods did i spell that wrong i don&#39;t know let&#39;s see npm start we&#39;re waiting for typescript to do its thing and it crashes okay uh is not assignable to payment intent create params object literal may only specify known properties and automatic payment methods does not exist in the type payment intent create preamps but it totally does it&#39;s right here we&#39;re in payment intent oh wait hold on payment intent create params okay automatic payment method right here um all right so what does this interface look like enabled boolean yeah okay so that&#39;s what i&#39;ve got right anyone got ideas enabled and that&#39;s a boolean i forget how to javascript what&#39;s going on here um payment intent create params like the only other thing i can think of is that the version of stripe node we have so npm uninstall stripe and then reinstall it like maybe the version of stripe we&#39;re using here is just a little bit out of date so so much that like it doesn&#39;t have that new field that new field was just released this this last week so i yeah let&#39;s let&#39;s see if this is the deal npm run start and we will check it out just waiting on this thing to install i have been drinking this mushroom coffee lately by four sigmatic and it&#39;s pretty tasty uh which i put tons of creamer in it uh but it&#39;s good um so yeah anyone anyone hanging out in the chat let me know what your plans are for thanksgiving or if you&#39;re not in the us and you don&#39;t celebrate thanksgiving what are your plans for the rest of the week curious to hear what folks got going on hey look at that it&#39;s listening on four two four two okay so this means that i think my hunch was correct in that um the the issue was that it was just using an old version of the types for stripe node like for some reason the version bump didn&#39;t work so uninstalling and reinstalling stripe node seems to work um okay so now that that&#39;s up let&#39;s go back in here to our spec for the payment element and we&#39;ll rerun all of the tests here i&#39;ve got like some hotkeys enabled for running tests in vim so i just use leader l so my leader key is inside of in my leader key is space so i do space l and that will run all of the tests in the file i don&#39;t actually know what l stands for but um yeah that works for me you can also do like um either j or leader h and that&#39;ll run the test that you&#39;re on top of it failed because i&#39;m not in a i don&#39;t have a server running all right so we&#39;ve got node node type script ruby those are all passing why don&#39;t we jump into python and play around with python for a little bit so pip dash m then then or no python python 3-m venn vend i can remember this stuff okay maybe this is just python-m oh gosh python bend how about so vend inactivate we want to activate the virtual environment okay we&#39;re here tip install requirements.txt is it dash r install pip install what no one&#39;s no pip no module name pip um okay uh let&#39;s see so whoa all right so i just accidentally closed out of that terminal okay server python um what this should totally work why doesn&#39;t this work all right whatever let&#39;s try another language cdn to go go run server all right we&#39;ll allow those to come in open up a new tab here and we&#39;ll go into our tests and run all of our tests again now the go server up and running all right fantastic so go should just work fine that&#39;s great um let&#39;s go into java uh i can never remember the command for java so java we want to build all the dependencies um oh i guess we&#39;ve gotta we&#39;ve gotta package them too so maven package and do this thing um all right so it&#39;s gonna package everything up install the dependencies with maven and now we&#39;re going to start up the java server and again we should be able to confirm whether or not it&#39;s working by just running our specs all right i think the server is up and listening on 4242 that&#39;s great from the tests we&#39;ve got a failure fantastic all right so what we want to do then is go into java no payment element java [Music] and this is the the java source so the things that are changing okay so create payment request we no longer are receiving like a body for creating the request the payment intent anymore um instead we are just using a get request so that we also have to update this so this is going to be payment element um and instead of post this is a get and we don&#39;t care about yes yes we do okay we don&#39;t need to deserialize the incoming body anymore we aren&#39;t going to set the payment method type we&#39;re going to set the currency to a hard-coded euros and then we need to also um we don&#39;t need to do anything about acss so i&#39;m going to delete all of this okay so payment intent create params um just be params and we can use that as the type here and then we&#39;re going to create a new builder and we&#39;ll call dot dot build after we&#39;re done sort of constructing all of payment intent create params and then we&#39;re going to pass those here params but the thing we&#39;re missing is we want to call set automatic payment methods so i can never remember the names for the methods so i&#39;m pretty sure it&#39;s going to be like set automatic payment methods and then we have to use like the automatic payment methods builder thing so like payment intent create params let&#39;s see okay so this is the class we need in stripe java and the thing that we&#39;re trying to call is like set automatic yeah okay so set automatic payment methods is the builder method we want to call and then into this builder method because we&#39;re passing like a nested hash we also want to pass the types for the automatic payment methods so here we need to do something like initialize a new instance of this sort of inner class so this will be something like payment intent createparams.automaticpaymentmethods.builder um dot set enabled true dot build and that&#39;s gonna be that&#39;s gonna be the argument into our into this sort of like interface here also there&#39;s like styling like i don&#39;t know i haven&#39;t written i don&#39;t write java java enough um i need to like learn the styling is this supposed to be like two spaces or all the spaces i don&#39;t know okay so payment intent create prims we&#39;re building out a new set of params we&#39;re setting automatic payment methods we are um setting a currency setting the amount this is where we&#39;re creating the payment intent we updated this to be a get request so let&#39;s um re-install dependencies we don&#39;t actually need to do that but um whatever and then we ah okay so this is another thing that has tripped me up a couple times so i don&#39;t think we actually want to call that builder um how does this work uh stripe box um payments payment element let&#39;s see hey victor how&#39;s it going welcome we are hanging out and going through the payment element updating a bunch of github examples to use the um the latest payment element that&#39;s this whole thing here and right now we&#39;re hacking on some java but we were just trying to play with typescript and node and some other things so let&#39;s see what this looks like in java oh dot builder is a lowercase method and we&#39;re not using the new keyword so we&#39;re not initializing anything the way i did this before with the other sample was a little odd so um okay hopefully that works let&#39;s see if we can get the types to pass um victor where are you from where are you joining us from okay can&#39;t find symbol on so the way that i&#39;m like reading these error messages too is like first of all i look at error and i see okay there&#39;s like some errors going on fail to execute and then the next line down here it shows me like the exact line and character that i&#39;m breaking on so line 83 and that means this line here ah so this one is also lowercase b i bet yep okay so let&#39;s try this again and we&#39;re going we are going all right all right okay if this starts up we&#39;re gonna fire it up in the browser here we go so let&#39;s see here localhost 4242 refresh the page and this is what we&#39;ve got going on so now this is all working with java so that&#39;s pretty neat all right so we&#39;ve got our java situation figured out we&#39;ve got our wait did we run we didn&#39;t let&#39;s run the tests so let&#39;s fire that back up jump in here come into the specs we&#39;re going to run our r specs once this starts all the way from russia cool very cool welcome it&#39;s late is it late i guess i&#39;m guessing it&#39;s late it&#39;s probably super late midnight huh all right so let&#39;s run all the tests again now that we&#39;ve got the server up and running boom all the tests pass fantastic and these are just our spec like ruby tests i love ruby ruby&#39;s my fave and that&#39;s what i&#39;m like most comfortable writing tests in so that&#39;s what we&#39;ve got our tests written in all right so we&#39;ve got we are uh go is working java is working node node tied script ruby why don&#39;t we work on dotnet okay so payment elementserver.net.netrunprogram.cs this should fire up the dotnet uh oh um oh man what is the name of the frameworks yes ruby for the win igor for sure the framework i&#39;m guessing is like dot i don&#39;t know at 5.00 or something can i run it with that no gosh okay how about how do i i am getting a phone call um [Music] all right i don&#39;t know who that is don&#39;t know who that is ring-a-ling i get so many phone calls um okay so what about yes so what i want to do is like figure out which um which dot net frameworks we&#39;re targeting which is like in one of these files here somewhere i thought it was like in solution okay uh okay here so net core app so net core 3.1 or net 50. so let&#39;s try this again but with dot net core 3.1 and we&#39;ll see if we can get this c sharp program up and running oh my gosh look at that cool all right so now we&#39;re up and running with c sharp in dot net that looks good let&#39;s run our tests which um i&#39;m not very organized i like delete stuff on accident like the tabs and such but okay sweet all right so net is working that&#39;s amazing um okay so now we&#39;ve got net go java node node type script php php and python are the ones that are hanging out leftovers uh okay so php is odd php is a little different than the others so let&#39;s go let&#39;s go hack on php so um for php we don&#39;t get we don&#39;t use this shared client so for the rest of these integrations we use the same html and javascript on the client but for php we use a separate public directory that is right here and i am just going to go through this public directory inside of finder because we don&#39;t want any of these i&#39;m going to keep card because we can just reuse it i&#39;m going to rename card to index and i think we don&#39;t need any of those all right so those were all different files that we needed in order to get a bunch of different payment methods working with php before but now we can just change this to index and inside of here what we want to do is okay so when i&#39;m reading php i want to start at the top and sort of work my way down so here we see like require once shared php and so i want to go like jump over to shared and see what this is actually doing and so here this is loading our dot n file make sure that exists mine&#39;s right here um web hook secret domain those probably don&#39;t matter right now well they uh yeah the domain shouldn&#39;t matter um well i can&#39;t remember no it shouldn&#39;t matter because when we&#39;re doing what happens is like after you pay no matter which payment method type you use by default on the front end it&#39;s going to redirect back to some return url but we&#39;re using the um window.location.org or whatever to come back so that shouldn&#39;t matter okay let&#39;s see all of this makes sense oh we&#39;ve got to change our setup info um payment element this is just like for debugging you don&#39;t actually need this bit for production and then we&#39;ve got we&#39;re initializing a stripe client down here inside of shared so we don&#39;t have to do that inside of index so that&#39;s cool so inside of index when we&#39;re calling payment intents create again we don&#39;t want to pass payment method types anymore now we&#39;re passing automatic payment methods and um here we&#39;re going to do enabled is uh true pretty sure that&#39;s what it looks like in php and the currency let&#39;s say it as euros um and then inside of php what do we do here so we&#39;re saying when the dom content is loaded we&#39;re going to set our publishable key and then we&#39;re going to initialize an instance of stripe elements this is actually like going to be a juicy part of this episode because we actually have to like set up the payment element because we yeah we&#39;re starting basically from scratch with this php file so what we need to do before we even initialize this element though is have that client secret for the payment intent that we just created so here what we want to do is we&#39;re going to initialize this with something called the client secret this is brand new and is part of payment element it you&#39;ve never had to do this before with the old stripe elements for cards so this is a this is a new thing so inside of here what we want to do is we&#39;re going to render the um the client secret for the payment intent which is up here so we can use php&#39;s like shorthand thingy for rendering out and here we can do like client secret and i think that should spit out the client secret into the javascript right here because we&#39;re like doing server side rendering php did this well before javascript made it cool again so uh yeah okay so then the next thing we&#39;re doing is we want to create a new kind of element called a payment element and then instead of card here we&#39;re going to do like payment and this will be payment down here also and then this is going to be payment element and then when the form is submitted so when the form is submitted we&#39;re going to prevent the fault we are going to disable the button and then we&#39;re going to confirm the payment so instead of um calling confirm card payment here we&#39;re going to just call confirm payment and instead of passing in the client secret here we passed it in above and confirm payment is going to take in uh an object here and this object will accept in elements the elements object that we created right here above and it&#39;s also going to take in a confirm params which will have a return url that is constructed of window.location.org i think slash return.php so this return.php bit is i just like have that convention that i call it return that&#39;s kind of like where customers are going to be sent back to after they finish after they finish paying and then in this case we&#39;re not actually getting a payment intent back because we&#39;re going to redirect so we don&#39;t actually need the payment intent there or it&#39;s payment intent id we&#39;re going to change the header to payment and we&#39;ll just remove the test information we will remove basically everything and then here um payment element payment details or something and we can call the div again payment element um i don&#39;t remember what that&#39;s called and then we just have submit button so let&#39;s see if we can fire this up so we&#39;re going to say composer start i think all right so we&#39;ve got this up and running because we&#39;re using php and we&#39;re doing that server-side rendering thing my tests are not going to work but um so we can just run through it here a couple times and see how it works so we click on pay and look at that okay very cool so we&#39;ve got a payment intent back here&#39;s its id it succeeded it was with euros here&#39;s the payment method very cool let&#39;s restart the demo let&#39;s just play around so like yeah what we could do here is if we&#39;ve got shiro pay we can just say like jenny rosen is the person paying click on pay and then in practice you would be like redirected to the shiropay interface but in test mode or redirected to this test payment page we can just say authorized test payment and then we&#39;re redirected back to our return.php i don&#39;t know if you can see that we&#39;re redirected back to that return.php spot where we also have the in the query string parameter we have the id of the payment intent the payment intense client secret et cetera et cetera et cetera so that is looking good so i think php is good to go um so the only one we&#39;ve got left is python which for some reason i don&#39;t know i don&#39;t know what the deal is so if i just try to run like python server um i don&#39;t think wait what it&#39;s just gonna run no way wow okay so i thought i had to like set up a virtual environment get things installed correctly etc etc etc but maybe i don&#39;t all right so let&#39;s see what we&#39;ve got going on here so for create payment intent again this becomes a get request we don&#39;t need any of the incoming data we don&#39;t need the payment method type or currency i&#39;m actually going to move all of those params down and inside of the payment intent create call so that we don&#39;t have a separate situation going on so here we&#39;re just going to say um oh gosh create and it&#39;s going to accept in what is it amount that&#39;s going to be 1999. uh currency is going to be euros and then automatic payment methods um is going to be enabled true python has a capital t for true that&#39;s cool right okay let&#39;s see if we can just restart our server here and if it will just work invalid api key provided amount something something something what why i don&#39;t know what what&#39;s going on okay so create payment intent create this should totally work all right let&#39;s go let&#39;s go take a look um at the docs for creating a payment intent um in python oh their keyword arguments at the top okay cool very cool i forgot all about that all right so these are not it&#39;s they&#39;re keyword arguments but the nested ones are dicks which is kind of confusing but whatever um does anyone in uh in the chat use python on the daily curious to hear if you that is your lingua franca your language of choice your uh preferred language oh look at that we&#39;ve got it we&#39;ve got it up and running it&#39;s working all right let&#39;s run our tests and pretty cool pretty cool what that means is that we&#39;ve got a new payment element server in eight different server languages so that&#39;s pretty sweet uh all right so let&#39;s call that good oh there&#39;s one other thing i wanted to change and that is in the cli.json here we want to add another integration called paymentelement and what this does is this works with the stripe cli so i can say name is payment element and for now i really just tested the html version so i want to just only include that and we&#39;ve got servers in ruby node python phpjavago.net and typescript very cool and yes all right okay all right what other changes do we need to make i think we&#39;ve got to make some docs changes because we now have like sort of a different style accept a payment with payment element all right stripe elements powerful okay um uh with the payment element and then we&#39;ll update the docs to point at uh that payment element doc which went here it is um no it goes back here yeah payment element okay okay how to run locally you install it we we definitely recommend installing with stripe samples create so stripe samples create accepted payment then you would pick payment element and then it&#39;s got several implementations pick a server we don&#39;t have php slim anymore pick a client for now we&#39;re just going to have html but we can come back and add the react client you can also clone it and then update all of your dot end files manually you don&#39;t technically need domain for this one okay okay what&#39;s going on here uh right for the web hooks the web hook implementation isn&#39;t changing from what we had before so yeah not going to touch that and this should be good to go all right and let&#39;s let&#39;s take a look on github all right accept a payment we&#39;ve got some pull requests here uh we&#39;re going to open a new poll request and then have some folks review it something okay add new payment element integration and also the other thing i do or i like to do when i&#39;m opening a pr is just sort of spot check the files that are in here just to make sure that um what i added did not seem way out of line okay so payment element this is the new index.html file very little html look at that 36 lines for the entire page that&#39;s the shared client that&#39;s like the shared html client and then the shared html javascript or html javascript the shared index.js like this is the javascript that we write um there&#39;s not a ton that&#39;s required again like this is sort of the new bit here where you&#39;re initializing stripe elements passing in the client secret creating a payment element mounting that as a payment element and then yeah we&#39;ve got the rest going on here actually this is one change i want to update so like we don&#39;t yeah we don&#39;t need those anymore and those don&#39;t make any sense with the new payment element because you don&#39;t get back a payment intent uh you unless you force not redirecting or something like only if it&#39;s needed or something like that but i think the most common case is going to be you finish payment and you redirect to your return url no matter which payment method type you use that&#39;ll keep it more consistent easier to maintain etc etc remove uh single page app payment element response or something from create or confirm card payment it was like the leftovers from confirm part card payment uh get push origin this one okay what else we got going on here the return page doesn&#39;t change but it was just copied from the other uh the other integrations that we have um okay so this create react app example is there but i guess like that is kind of like an open to-do so let&#39;s um one one thing that we can do is make this a draft pull request which is super handy it means like you&#39;re still working on it and here we can say this is a work in progress and that we still need um to implement for react and we can preview this to make sure it looks like a checkbox as it should and then we&#39;re going to say draft pr the nice thing about doing a draft pr is like as you&#39;re working you can keep making like keep pushing um i don&#39;t know what&#39;s going on with oh so um hiberia one of the contributors to stripe samples um set up ci and it has been working super well and i really like it as part of that um he set it up so that if you have multiple builds going for the same branch then it&#39;ll cancel the old ones and only run the most recent ones so like all of these were actually just cancelled because uh we made a push before the run ended which is super handy and makes it so that you don&#39;t run out of github actions juice too soon um alright so what do we got going on next i guess why don&#39;t we work on some react stuff uh so if we jump into the server node plays the nicest with react so i&#39;m just gonna say npm run server here or no and npm run start and then we&#39;re going to just like let the node server run on localhost 4242 and then in a separate tab we&#39;ll go hack around on the react stuff so uh samples accept a payment payment element and then inside of the client we want to go to the react create react app implementation and actually what we want to do here is we want to go into the client react and then i think this one is also start npm start npm run start yes npm run start or npm start i don&#39;t know uh okay what is maybe npm install see yes does anyone yeah like in the in the chat have you used create react app before are you using create or npx create next app now next js definitely is getting a lot of traction curious to hear if other folks are using next i&#39;ve also seen a lot of buzz over the last few days for remix run ooh let&#39;s take a little break here and look at remix dot run check out this experience so this uh you&#39;re scrolling down you&#39;re like okay this seems pretty cool and they&#39;re like oh what is this flashing and it tells you the different regions that are being shown based on what javascript is running pretty cool right but wait till you see this look i&#39;m not doing anything i&#39;m just kind of like hovering here and if i scroll what you can see that network tab like the simulated network tab loading it&#39;s like without remix you&#39;re going to be so sad because you have all these loading bars everywhere but with remix you&#39;re going to be so happy because all the files run at the same time so yeah kind of a fun kind of a fun little breakdown there so remix seems like it&#39;s definitely picking up a lot more steam too so i don&#39;t know about that but right now a lot of the samples still use create react app it&#39;s very simple to get started and hopefully we can actually make it work uh npm run start i don&#39;t know if you need to actually say run star or just npm start or something um what is why is this sad cannot find module scripts slash start package json inside of package.json it says the script right here is react scripts start can i not run this see uh npm wait node let&#39;s see no dash v uh remix run js on rails uh yeah it&#39;s like i don&#39;t know uh oh also i guess this view is like not helpful huh because you can&#39;t see what i&#39;m typing um yeah remix run it&#39;s like i don&#39;t know i need to learn more about it it seems cool what about what was i doing here node v which does this matter what&#39;s going on npm start i don&#39;t know why it&#39;s not doing this come on uh there&#39;s likely additional logging above the output blah blah blah okay this is what we&#39;re gonna do we&#39;re gonna start from scratch um we&#39;re just gonna blow away react create react app that was copied from the cards integration and uh yeah now like we don&#39;t actually need all the stuff that was there because we&#39;re gonna start i think mostly from scratch we have to kind of like rearrange where the payment intent is created in order for it to work anyway so um yeah so roman&#39;s like yeah lol remix run js on rails and then it&#39;s all just server side rendered and like it&#39;s so funny uh igor is like yeah just working on back end uh who cares about styling divs i this is my this is the drum i keep beating is i want to let other people style stuff because other people are so much better at styling things and uh yeah i like i depend a lot on other people making things look really good um okay so uh npx create react app and then we&#39;re going to call it react pro cray uh oh uh oh no not npm npx npx is like npm install and npm run something something um kind of like a little combo hey synon what&#39;s up how&#39;s it going where are you based what are you doing for thanksgiving we&#39;re just hanging out talking about payment element and working on some open source so this is the payment element all of this stuff you get sort of out of the box with the payment element and so we&#39;re hacking on an open source sample where we&#39;re showing how to implement that so it looks like this we got it up and running for all of our server stuff so we&#39;ve got servers implemented in rubygo php python node go java.net and now we&#39;re it&#39;s all working in html so now we&#39;re like just playing around trying to get it up and running with react um so right now we&#39;re waiting for create react app to finish um but yeah curious no one no one is uh no one has mentioned what they&#39;re doing for thanksgiving uh maybe is no one based in the us roman i know you&#39;re based in the u.s man uh yes the scroll style in that library or like the scroll style on the landing page for remix run is mind blowing it&#39;s incredible and i think um oh gosh what&#39;s his name ryan florence was just mentioning on twitter the other day that uh they built it in like an afternoon um let&#39;s see ryan florence yes this this person uh yesterday was bragging about how awesome they are just kidding uh they basically said thanks to tailwind and something else the landing page took like an afternoon probably not after it was like a couple days let&#39;s see uh here we go look at i built the entire scrolling experience in just a few days it was entirely because tailwind css is amazing and react i was like this is like the craziest experience i&#39;ve ever had uh like this remix yeah if you haven&#39;t checked out remix.run this is also like good marketing right like a good built-in engineering as marketing i think rob walling would call it right like um because when you land on this page it&#39;s just like whoa this experience right here is cool enough that i want to share it with all my friends and with all of you so you&#39;re going to oregon right on very cool super cool which which site are you talking about checking out because this remix run one is the one that i was uh that i&#39;ve been playing with but yeah if you&#39;ve got another one uh let let it fly let it fly okay can we start our create react app now all right looks like it&#39;s going um and we&#39;re up on localhost 3000 that&#39;s good let&#39;s see is it actually going to load hey look at that we got some react stuff okay um all right so what we want to do is in order to set up i guess we don&#39;t need oh gosh we&#39;re in the wrong one we want that server to keep going and then over here we&#39;re gonna jump back in here um so inside of the client in react create create react app in public index.html we probably want to change some of this stuff i&#39;m just going to rip some things out to simplify yeah and this will just call payment element stripe sample super cool um and then in the source i guess okay so we&#39;ve got app.js app.js looks like this and i&#39;m gonna like also try to reference what we&#39;ve got in our custom payment flow for the create react app stuff um just so that i can see what&#39;s going on okay so down here yeah all right so what we want is we just want to like remove all of this and replace it with our own app so we&#39;re gonna start with a fragment and then inside here we&#39;re gonna have a header that&#39;s like payment and then we will have a form actually no then we need see is that oh i was looking at apple pay let&#39;s look at appjs because i don&#39;t know if we don&#39;t actually need any routes do we actually have routes uh the build your own that has awesome scroll feature oh i&#39;ve never heard of that and then the dev makes a lot of react slide libraries okay uh cool i guess maybe we do want routing so that we can have the return path uh maybe or no we were using a return element in this other one do we need a i don&#39;t think we need react router at all for this so should we just um and then here when we had like the card element we had a card form and okay actually you know what let&#39;s look at the docs and see what the docs are doing for this um docs are always right um [Music] the docs are always right accept a payment uh yeah react on the front end app.jsx so okay so we need to install uh stripe.js the npm module we need to install react stripe.js so let&#39;s do both of those now while we&#39;re thinking about it so npm install um stripe.js and react.js roman what am i doing for thanksgiving uh fun story not fun story but my folks my parents usually do a kickball tournament with a bunch of neighbors and um they come down and we hang out we eat donuts and coffee and play kickball kids versus adults and it&#39;s always a good time sometimes there&#39;s snow on the ground so we play around in the snow and slip around um but yeah this time should be pretty low-key and then we&#39;ll just like hang out at my folks and have dinner and usually they invite the whole neighborhood and a bunch of neighbors come over and it&#39;s a good time uh okay so we&#39;ve got you know what i&#39;m thinking we should do is actually like oh what hold on um i did not mean to install it at the top level so we gotta go into client react npm install this same stuff um okay so then once we&#39;ve installed that i think do we want to import a checkout form and do it the same way i&#39;m guessing that&#39;s what we do want to do right like uh yeah okay so we&#39;ll create so this elements component is the elements provider or like from the elements provider which is part of react stripe.js this checkout form is something that is custom that&#39;s part of this example here that uses the new payment element component from react stripe.js and so yeah let&#39;s do it that way so that we follow the docs and so that our examples match what we see in the docs i do think that is a good best practice and while we&#39;re waiting for that we can just come over here payment element client react create react app source let&#39;s add um checkoutform.js and in here we will say constcheckoutform is a new component that&#39;s going to return something form and let&#39;s actually make it the same as this so we&#39;ll just copy all this um okay so we need to uh import payment element uh from at stripe react stripe js that gives us this element here okay and then this checkout form needs to be wrapped in an element provider so here maybe we might say elements and we&#39;ve got to pass some stuff into it and here we&#39;re going to say checkout form and this will be like import checkout form from checkout form okay and this element provider is requires that we pass it reference to a stripe to an instance of stripe or to a promise that will resolve to an instance of stripe for like the stripe.js client-side stuff so we need to import um load load load stripe from stripe stripe.js so stripe stripe.js is just like a super small npm module that wraps up the logic for like installing basically just like installing the javascript tag and like importing stripe.js from jsonstripe.com which is a best practice and here we can say um con stripe is load stripe and then usually you pass it your publishable key and here in order to get our publishable key we actually want to fetch that from um from the server so that we don&#39;t have to like mess around with environment variables right here so fetch flash config then our r.json so we&#39;re just going to convert that response into json and then i think we can pass that in here publish publishable key let&#39;s see i don&#39;t know if any of this is working as expected um we&#39;ve got an error oh this should be straight and okay you may need an additional loader for these loaders cannot use a weight outside of an async function gosh did you know okay so like cool cool story about dino is that you can use a weight outside of an async function uh okay so then if that wants to be not cool and do that i think we actually need to like do use a use effect hook and everything um so let&#39;s see how this is doing it here um yes so we&#39;ve got to do like a use effect fetch the client secret and then use set state and blah blah blah uh okay elements requires options and the stripe promise stripe promise okay so this this is all right in the example this is called i promise and that&#39;ll be passed in as soon as um it like installs the javascript tag and stuff and then it like gets that back whatever i guess we also need to pass in options which is going to be something that we create up here i don&#39;t know what it&#39;s going to have yet and then we have to use use effect so we want to import use effect from react and then we&#39;re going to say use effect and this i don&#39;t know what dependencies we need this one passed in no dependencies and then it creates the payment intent on the server in our case it&#39;s just a get request because we&#39;re not passing anything down and so this gets less complicated and then we&#39;re going to call set client secret in order to call set client secret we need some sort of uh situation here so here we can just say like client secret and then set the client secret like that and then so we need to do use state use state and this is going to be client secret and set client secret okay so this whole use effect thing is just so that we&#39;re only firing this ajax request like one time and you have to do it inside of the ajax request and you also like if you want to use async await there&#39;s like all these weird things you have to do so we just use that then and live with it it&#39;s fine yeah good old use effect what is up j-dog war welcome how&#39;s it going what are you doing for thanksgiving um okay so now we should have a client secret which i think goes in options i&#39;m guessing uh client secret i don&#39;t know let&#39;s see um yeah turkey ball what&#39;s turkey ball wait roman like yeah i i&#39;ve never heard of turkey ball uh okay so we can also pass in the or we can use the appearance api so we&#39;re not using appearance on the other parts of the sample so i&#39;m going to kind of skip that but you can totally pass in this other appearance thing to configure the look and feel and then i guess you want to say like if you have a client secret and or like if you have a client secret then run it this always is like reads weird in um in jsx to me so you have to say like client secret so if you have a client secret and that&#39;s truthy which uh empty string is not apparently in javascript and and then do all of this stuff um that&#39;s kind of like an if statement but without having to write an if statement um also uh yeah roman what is turkey ball i know like a lot of people do these turkey trots where there&#39;s like you know charity runs or whatever that you can do um on turkey day or whatever but uh yeah i am not familiar with tricky ball okay what did i oh you know what my publishable key situation probably also needs to be yeah gosh okay let&#39;s um immediately invoked function expression and can we make it async and then does everything become happy okay cool uh import checkout form from checkout form is not working so export uh does that work can&#39;t resolve uh defaults no export yeah default sure uh then this just becomes checkout form maybe no does not contain a default export it totally does i just did it okay um how does javascript work again uh export checkout form does this work holy moly how come i am like this is this the second time that i&#39;ve been having module i swear you could do like export uh checkout form attempted import error checkout form is not exported from checkout form uh it totally is oh synon says uh stripe docks are awesome so clean thank you that&#39;s uh that&#39;s huge i yeah we we work super hard on them if you find issues please let us know we&#39;d love to fix those and improve also if there&#39;s anything that you&#39;re you&#39;re finding confusing as you&#39;re going through please let us know i like would be happy to chat um also if you&#39;re building a stripe integration and you just want to like chat about it or hang out on twitter i would love to love to visit um am i not remembering how to export default things from uh okay export default fun okay gosh do i have to do it like okay okay good is this that is what i did that&#39;s not what i did i need to restart this thing just because okay export default now this should be like not the structure well that was weird i was like jumping around too quickly and uh i closed the tab that was like hosting the streaming thing okay we&#39;re back so this this like arrow function thing i messed that up so we&#39;ve got to go back over here and do this okay elements is not defined all right we&#39;re back we&#39;re back in a shape we&#39;re back into shape so import elements from at stripe react stripe js um gay dog war just chilling at home cooking for the family got a new job finally relaxing after going to the grind watching your process cool super cool um yeah i uh i think roman was making fun of me not you j dog war uh yeah that sounds great where uh like what what kind of jobs you get what are you yeah were you working at j dog war and uh yeah tell us tell us how the interview process was i know it&#39;s i know it&#39;s a grind for sure it&#39;s a grind but i&#39;m curious like yeah what uh what was that like handle submit is not defined okay so now i think we&#39;re like running into issues here conf handle submit make this async is loading is not defined um okay so import use state from react use is loading set is loading true i don&#39;t know how does that actually work what is it what&#39;s going on over here how are they using is loading uh so [Music] wait what okay i don&#39;t know why this is happening what are we doing here why are we retrieving it i don&#39;t understand that part i i get down here when we hit submit okay so handle submit we&#39;re going to prevent default if there&#39;s no striper no elements return yep cool set is loading to true confirm the payment and then if we get an error show the error otherwise set is loading to false okay all of that makes sense um but what i&#39;m confused by is why oh you know what it is i bet we&#39;re using this same page for yeah we&#39;re using the same page for both like the return url and for the yeah okay so i&#39;m gonna do that a little differently i think and we are going to actually he&#39;s loading we&#39;ll start with false yeah we&#39;ll start with false that should be fine um okay line 10. okay stripe is not defined okay so in order to use stripe we need to import the use stripe hook from uh at stripe react stripe.js so this is a hook that will give us access to that stripe object this con stripe is use stripe the one that is the result of the stripe promise resolving and then elements is not so similar deal with elements so here we say use elements um and down here we can say uh elements so const elements is use elements a dog works senior software engineering physician with a tech company based out of denver oh there&#39;s some cool ones in denver i&#39;m trying to remember uh we were just there there&#39;s a consulting company we were talking to overall interview wasn&#39;t too bad basic leak code medium level coding interview along side a systems design interview gosh those leak coding interviews uh i haven&#39;t done leak code in a long time that is like the hardest part of like the interview process is like doing all those projects to get ready you know like um yeah like just to get uh to get set up for your job uh or like for the job interview process you can do these leak code exercises um beat code and they are no joke these things are not easy these questions uh wow it&#39;s changed a ton since i saw it last explore companies and communities yeah so the questions will be like make a red black tree and then make itself make some self-balancing tree with c plus plus you&#39;re like what no thanks that does not sound fun um you know what the the site that i love using for like interview prep it&#39;s called interview cake and last i checked it was like 100 and maybe like 150 bucks or something what is the full course wow okay 249 but uh the way that this this site walks you through a bunch of stuff is pretty neat like i&#39;m a big fan of it there&#39;s it covers like all the basics that you would want and expect from like interview prep like a really solid interview prep and so yeah i like it um all right i guess we&#39;re also doing a set message situation here um payment all right at least it&#39;s not crashing anymore but what&#39;s going on here what is going on here console unexpected stuff all over the place okay where is this yeah uh roman says makes me sweat yeah for sure it makes everyone sweat they should call it sweat code instead of leak code it&#39;s tricky i think there&#39;s a lot of folks that really love it and it&#39;s super fun for them and i mean that&#39;s that&#39;s cool okay so the thing that&#39;s happening right now this is a little bit confusing if you if you&#39;ve not seen this before so what&#39;s happening is we are making a get request to slash create payment intent that is correct we want to make a get request to create payment intent but what&#39;s happening is we&#39;re making this to localhost 3000 which is where our client where the react client is being hosted but our server is being hosted on localhost 4242 and so what we need to do is some magic inside of package.json so that we are proxying our api and i think it&#39;s something just like proxy and i don&#39;t remember what the thing is so we&#39;re going to look it up up here where we&#39;ve already figured it out once and oh it&#39;s just a string okay um okay and now we i think we need to like restart a bunch of stuff after that so let&#39;s just let&#39;s call it good and restart a bunch and see if it works so we&#39;ve got our our back end servers running on localhost 4242 our front-end client is running on 3000 ooh baby look at that amazing amazing oh gosh i&#39;m so pumped all right so the it does not look pretty but we can fix that i mean we could fix it a little bit right um okay so that what&#39;s happening now is like when the back end i&#39;m sorry when the front end server the client the react client&#39;s server that&#39;s hosting um the create react app receives a request that it doesn&#39;t know about like it doesn&#39;t have like a built-in route for it will proxy or like sort of forward that on to this other place so we&#39;re forwarding it on to localhost 4242 which is where our backend server is running and listening and waiting for get request to that create payment intent so it&#39;s creating the payment intents and then returning those client secrets for the payment intents all right oh gosh hard to see like that huh all right so i was like doing a presentation recently and someone pointed out that my filler word is so and as a result i will try to not say that anymore but it&#39;ll be really hard uh we want to make this page look better and not be so oh i said it not be as wide as it is and the way that we&#39;re going to do that is by stealing the css we&#39;ve already written for the for the html version and we are going to grab all of it and we&#39;re going to dump it into app css inside of here and i think oh wait index.css all right one of those is going to be the right thing okay look at that immediately so much better all right so we&#39;ve got eps we&#39;ve got shiropay we&#39;ve got all these and again you can just enable them from the dashboard what&#39;s really cool about this too is this is like a pre-built component right this this uh this drop in react component was the payment element component so this entire thing is part of this payment element component so that is pretty neat let&#39;s actually try it out say pay now i don&#39;t know why the button is still showing and it&#39;s yeah okay uh all right authorized test payment and i&#39;m coming from canada okay so now we&#39;re back we returned and we have the payment intent id payment to client secret et cetera et cetera et cetera in the url we see the source was being contacted so the payments are working as expected and i think that&#39;s cool all right so oh gosh i i said it again oh gosh so what so what says synon oh like as in so what who cares that so is the filler word or that we use filler words i guess it doesn&#39;t really matter right just trying to get better trying to always get better let&#39;s remove these it&#39;s so hard not to say it&#39;s very hard not to say it uh okay we&#39;re not actually using this all right we do have some end to end tests inside of the inside of our r specs but i don&#39;t i don&#39;t think we&#39;re going to have time today to go through and write some e to e tests for react but maybe we can keep that as a open as an open to do all right what&#39;s up and usually i try to aim to having prs that are a little smaller than this but when we&#39;re adding an entire integration that covers a whole sort of use case this is one of the ways to go i guess now that we have create react app too we can go back and update the list of clients to include create react app so here roman says that one video application loom i think you can target filler words and edit it&#39;ll edit them for you oh this is uh descript dscript dscript is super cool so be script you can bulk edit your video as text and it will remove you can remove filler words it&#39;s very cool the thing that i was running into is a lot of the videos that i do i either want to have sort of a green screen background or i want to move myself around the screen as i&#39;m working when i&#39;m doing live streaming like this i use stream yard which is pretty handy there&#39;s a bunch of scenes i can sort of poke around and do different stuff but when i am doing pre-record i like to use screenflow and try to keep i don&#39;t know keep myself on screen and moving around but when you&#39;re using dscript it doesn&#39;t have multiple sort of video inputs right now they just do one video input so i would need to like kind of edit it and move myself around and then edit it to remove the filler words and then edit it again to make sure that i have the right code on screen and everything so i found it to be a little bit cumbersome but uh it&#39;s a pretty cool tool uh okay so this one react craw okay and what else do we need okay so that looks pretty good uh then yeah let&#39;s review our docs here for the create react app uh okay getting started oh gosh you know what this is gonna be all wiped away because we started from scratch so let&#39;s grab this okay all right accept the payment examples in react for payment element okay so react client sample for that okay runs independently of the server start the backend servers choose one of the servers and then you npm install your npm start it&#39;s going to start your backend server on 3000. they need it okay yeah cool all right uh for react okay all right that is all looking pretty good i think okay so this is feeling good the css seems good ish i mean it looks fine maybe we want to put a main wrapper yeah let&#39;s do that in in react um uh app.js inside of payment element client yeah that one so down here let&#39;s make this a main i think there&#39;s some css that depends on this being a main tag maybe oh gosh uh report i broke something report web vitals okay we don&#39;t need that anymore uh oh gosh i broke so much i broke so much that&#39;s the server we don&#39;t want to restart that one let&#39;s restart the client and come on server&#39;s running client is trying to start and it&#39;s not starting there we go big money big money big money big money schwing all right that is looking tight i like it i love it okay all right what else do we got going on here i think that&#39;s pretty good i&#39;m just gonna call that good for now and hopefully that&#39;s useful yeah so if you&#39;re using the payment element or if you&#39;re curious about the payment element would be yeah happy to chat uh this was all about just taking a one-time payment but there&#39;s another sample called subscription use cases that i think we&#39;ll do another live stream maybe next week sometime after the holiday where we go back through and we update our custom form subscription flow to use a uh to use the same payment element thanks victor uh yeah have a great night cheers and yeah thank thanks everyone for sticking around hanging out and i&#39;m hoping to do more of these streams again igor yeah i i mean to get back to clearbnb doing some more rails work but i yeah i just like have not prioritized it i&#39;m also a little bit like stuck on what to build next and maybe what sort of what features you want to see that we haven&#39;t already covered so if you&#39;re curious or if you&#39;re excited about clearbnb uh please let me know sort of what features you might
