## Transcript

foreign [Music] [Music] [Music] foreign [Music] [Music] foreign [Music] [Music] [Music] foreign [Music] [Music] [Music] foreign welcome back to another episode of stripe Dev chats I'm CJ and I'm joined by my colleague Mike and Colin from clerk.dev and we're really excited to see today because we're going to talk about authentication and Colin has some really cool demos for us that we're going to go through all about authenticating your stripe customers and there's some really solid use cases in both the B to B and B to C uh spaces especially if you have a react application if you're writing uh next JS there's tons of great walkthroughs too in the clark.dev documentation so if you head over there you'll see options for Redwood JS which you know we're we've got our friends over there at Redwood I think we're super super excited to uh to pair with but before we jump into that we've got to go through some stripe updates so I'm gonna let Mike jump in and go and talk about some of his tabs here that he's got ready to go about some some upcoming stripe things that are that were actually just launched and uh yeah I'll let you I'll let you take it away Mike right on thanks CJ I'm gonna make this just a little bigger take up a little more of the space here and maybe zoom in a little bit so a couple of updates to go through um first of all there's an updated uh API on payment requests called paymentrequest dot can make payment uh what this does is it returns a promise and async uh response that lets you know if a wallet is ready to make a payment so this is helpful in cases where you need to check to see if someone has connected uh Apple pay um link or Google pay and as you can see here the syntax is pretty simple I'm showing JavaScript right now but what it gives you back is a dictionary essentially a Json object that shows Apple pay Google pay and link whether or not they're available to be used up next redirect to checkout uh and on the stripe API has been deprecated so uh this was a method that you could use on the front end to redirect your users to checkout it has since been deprecated because of our sort of preference for um using server-side uh redirects for this scenario um let's see anything I missed there CJ oh yeah this was um this was early early in the early stripe checkout days of the the new stripe checkout this was the way that we recommended most users redirect the checkout so you might either create a checkout session on the server and then pass its ID to the client and then redirect to checkout or you could pass in this object that had line items and you would redirect to try to check out client side but we found that it just wasn't flexible enough to meet the user's needs and so we stopped adding features to it a while ago and now it's officially deprecated so yeah you definitely don't want to use the client-side version because instead you can use the server side version where you can just fire up a checkout session and redirect to its URL on the on the server side so Bingo exactly so let me run through some of our other updates here uh we have a new um actually I'm going to zoom out on this to show it a little more in context we have a new docs section on no code on stripe.com docs uh you'll see there's a new tab added to the top here that shows you all of Stripes no code documentation uh in one place so this is a new hub for no code documentation it walks through all of the options for doing things with stripe without writing code so sort of configuration first meant for people uh to get up and running quickly uh and to get things done without having to go and spend a bunch of time writing code for specific use cases um I have taken a really strong stance on this that I think this is really important for developers to adopt as early as possible and when you outgrow no code things you can start thinking about updating your integration with something that's a little more code heavy if you haven't tried it before this stuff is really tremendous the pricing table is really cool this is marked as some code here because it essentially generates a script tag that you need to embed on a page somewhere so you need to be at least dangerous enough to do that payment links are really cool you can create a URL that anyone can go to to complete a purchase for any one of your products yeah so check this out let us know what you think no code scenarios are growing with stripe we see it as an important thing and something that's gaining a lot of traction in the developer ecosystem as well uh up next on stripe checkout we have the opportunity the ability to present local currencies so what this means is that you can set up prices price objects on your products that have multiple currencies in other words you can set up what a single product that say costs a hundred dollars U.S and you can set specific prices for other currencies that will show their currencies in their sort of local conversion here so uh if a user from the UK or the EU shows up and wants to make a purchase on my site they'll see it in their local currency I believe in the local currency as well there is an opportunity here to um uh set a a automatic flag to enable the payment methods that are available in those Lookouts too so lots of flexibility here for uh working with uh currencies in different um geographies and countries a couple events coming up uh this is going to feel like I'm just plugging my own stuff for a minute here but I promise you this is all about Stripes so uh in November I'm headed to the Caribbean developers conference in Punta Cana with Cecil who's normally host of our Dev chats here we're going to be giving a session on going from zero to revenue with stripe uh with a friend of ours from the Dominican Republic who's growing a company there his story is really cool very interesting super cool to hear about how he's grown his company using Stripes products as well as stripe Atlas which is one of our sort of product Suites that you can use to incorporate a us-based company and so that's how he's formed his business in the Dominican Republic super cool story looking forward to that event and I hope to see you there uh also in November that same week uh October 30th to November 2nd is all things open the open source conference in Raleigh North Carolina in the U.S uh I'm giving a talk at all things open on markdock which is our um superset of markdown it is a open source system for adding functionality to markdoc uh to make scalable Dynamic pages so actually everything that I showed you before for stripe documentation is all markduck powered so all this um is created by our docs teams using markduck and we created markduck to sort of solve this problem where documentation might need multiple languages it might need reuse of content within it there's functional Dynamic content on the page where you can add things and whatnot and so my talk here will be about the history of markduck and how you can use it on your sites and I'm actually working to convert my own site to using markdoc right now so we'll have some use cases for that as well so with that being said I think that's the news updates for today that brings us to my last tab going across the top here uh which is Clerk and that's why we've got our friend Colin here with us today to talk about clerk.dev uh Colin how you doing pretty good how are you thanks for having me yeah of course I'm doing great um why don't you start a little bit tell us about clerk tell us about yourself and then we can kind of get into the uh the story here yeah absolutely um you know me personally I've just kind of always been a software developer I always had a side project going and always kind of hated the alt step I built this great product and then I'd get to the odd step um and you know I always I always hated it for two reasons either like it was too hard to do or whatever I did just didn't feel good enough and I didn't want to spend more time on it and yeah I think really the inspiration for clerk was like looking at tools like stripe checkout where like hey I get this whole UI and it's beautiful and it's really easy to use and great ux for my customers um but on the off side like that wasn't really there like I was never as happy with something and so really with clerk um we've deployed these react components uh that make it really easy to drop a beautiful UI into your application gotta say that part so yeah I was looking at some of the components and I um I was saying that like one of them is the user button or something that gives you like your avatar out of the box with some you know ways that you can sort of uh you know log in log out Etc um that seems really handy and one of the one of the things too that I found with clerk was that a lot of it was very react Centric um so I'm curious like when you're thinking about uh you know as you're adding functionality to clerk are you focused primarily on react and and just react or is there like support for you know View and svelte and other you know a bunch of other Frameworks and yeah what can we expect uh in terms of uh front end front-end support yeah so I guess where we stand right now is we have a react SDK um but the react SDK is a shim over just vanilla JavaScript and so everything you do in the react SDK you could do through window.clerk um and ultimately make a you know a view a spell whatever uh SDK as well um that is on our roadmap to get to as well but um we do have some some brave souls that have built their own off of window.clark and you can get it going very cool and the clerk react SDK is all open source tune so that that's a good Guiding Light if someone's trying to do that got it got it awesome should we jump into jump into a demo here absolutely yeah happy to all right um great so this is this is our homepage I think Mike just had it up um the user button that CJ was referring to is this and this is kind of just another kind of component of sign up sign in uis that we really wanted to bring to people and make it really easy you've seen things like this before um probably and and so since it's a UI associated with auth uh we ship it but we'll do a demo of that as well um in terms of what we're going to do from a foundation perspective what I've done so far uh I've created a new next.js app I have Tech script turned on uh really just for autocomplete makes my life a little easier and then I've also installed the clerk nexjs package and I should be able to start this up um one other thing I guess I prepared ahead of time is um environment variables so these are the keys from Stripes dashboard and then on this other tab I'm actually signed in on the click dashboard and so we've set up this stripe Dev chats application uh within Clerk and now we're going to install it on our localhost so assuming this is running now nice this is the next JS hello world and I guess as the first step here we will um just put it behind a sign-in screen I should say um the API Keys they're just in the dashboard under API Keys that's where we copy pasted these from I noticed that nice little uh prefix of test underscores I don't know where we stole that from a little yeah the stripe inspiration throughout totally incidentally our teammate uh Paul just published a blog post on dev.2 so if you're interested in learning more about object IDs generally like how they work at stripe and like why we have those prefixes if you head over to dev.2 stripe there's yeah excellent blog post about how we design those and why why we start with those prefixes and uh yeah I love seeing it in the wild too because it's like okay yeah like that's actually really really helpful because when you see that that prefix you know for sure that is my test string um yeah so this is uh oh nice you have a similar okay we also wrote about how we did it nice okay we uh we predated you a little bit but you did that's writing about it you're gonna steal my uh my SEO traffic uh but no absolutely I actually have read that article um and the benefits are real uh so if you recommend if you're building an API tip to implement those prefixes very cool should I jump in let's keep going let's keep going going um all right so if you've used next.js before um underscore app.tsx that's the like entry point for the react application and since we want to authenticate the whole application that's where we're gonna do a lot of our work and so first thing we need to do is just pull in with the provider mm-hmm and this basically tells uh the component which in this case is the page about the user's auth State um if I just flip back here nothing's actually changed yet this isn't impacting the page at all um but now the Allstate is available to the rest of the application um next thing I'll pull in is the signed in component now what this is saying is okay now let's only render this component if there's a user signed in and so if I flip back now our screen is blank um other side of the coin we need signed out okay and I'll start just by putting photo signed out here yeah yeah really made uh this demo fantastic yeah auth is done uh and now we've got our our sign in so I dropped sign in component that's put the sign in um out of the box I guess I just had the default settings on so there's sign in with Google here people want they can come in and and set up you know any number of uh other social auth options in Dev we can just use default keys but then in production you'll need to actually go through and uh set up your own kind of oauth client Keys got it um we can sign in here so is that is that view to the sign in so that sign-in component like how customizable is that in terms of the look and feel and colors and branding and do you do that from your react code or from the dashboard or where does that happen yeah so let's give it a try uh so we got an appearance prop here okay and is it command space that's not it control space um so yeah there's a whole bunch of options for customization and I guess the it works slightly similar to um stripes appearance API uh so if you're familiar with that this will feel a little familiar um but let's hit some variables first so I always forget the intellisense thing so if I wanted to just set like color primary I think is something yeah color primary uh and I can I don't have a uh oh my gosh so cassidue has like a really funny page that's like all of the hex codes that are words and they're all hilarious but I've ended up with a yellow that killed my contrast but that's okay so yeah so variables is just like they're the cross-cutting um uh uh cross-cutting variables I can think of another word uh and so they impact the color of more than one thing I'm actually just gonna switch it to Red for my own contrast concerns but then what we also do that's I suppose slightly different than uh stripe um or not anyway I'll let you decide if it's different after um but you can come here oh wait I went to a screen the other can't see uh so every element here is addressable and so uh if I want to take why don't we take the uh form field input and if I go back here so not under variables but elements field input I can view I can like kill the Border radius on this so do border radius zero now we're getting square footage here um it actually works with anything uh so if I were to go into like my Global CSS and make a new class here that's just Foo and you back on color red uh except that's not that's CSS um then I can say hey instead of just like targeting this one attribute here let's append a class to our form field inputs and we'll just append to and now if you look here um sorry well first of all I got the background color but then you can also see that the foo ended up in the top um and so I guess what's what's different from stripe if you're really familiar with the internals which uh I don't know how many will be uh is that this is actually mounted directly into the Dom instead of an eye frame and so you can actually uh it's kind of a debate I think no one knows the best way to build these components yet um and so I think the the mindset of like a stripe approach where you have an iframe is like the component is entirely sandboxed and so external Styles can't pollute um the component but with clerk uh we were thinking about them we're like well that's not really pollution like maybe they actually want their styles on um so this strategy it's a it's a little risky um because of that like there's this intentional pollution going on um one example of that is like if I go into we're totally going to have plenty of time to talk about uh like I I was originally concerned this was going to go long but we're really going in deep here so if I set the the font size on the body that changes the REM and so everything here is scaled off of Rems uh and so that's that's kind of the best example of like okay we're intentionally get included that'll work with like the font family as well the whole thing is themeable right so you can make this feel like your brand you could uh you know have it blend in with everything else and not feel like a I don't know like a wart that you put on top of your app that's from something else that's really cool exactly yeah and I think with with sign up and sign in in particular like our customers were really adamant like it needs to be perfect um like like just the variables didn't get us through because that's what we launched with and so we needed to come up with this I know you can actually edit the CSS of everything um cool so that's customization um I'll sign in now oh I don't know if you caught that it went through clerk.share.lcl.gov those are the shared keys that we set up for people in development but now that we're signed in we have we're back to this hello world um from here I can let's show off that user button um uh I guess I'll I'll just drop it right above the component um I did import it I don't know how that got in there so in one of the demos too I saw that page props was being passed down into the clerk provider is that what is like the usefulness of that or uh yeah so I'm not doing it here you are right if you go to our docs um we really streamline the next JS stuff so that uh you get too quickly but basically in next.js because there's SSR um we ask for page props and so by default what I'm doing right now like there's no SSR turned on so it doesn't matter and that's why I didn't bother with it but um if you are using SSR this basically ensures that like the during the SSR run that the user is actually signed in and so this practically what it means that during SSR um if you pass page props then anything inside signed in will get rendered as expected if these are signed in if you don't pass page props this will actually gate rendering because it needs the front end to decide if the user is signed in got it yes so let me let me dumb that down to next.js101 uh oh and and you can tell me if I'm misunderstanding but the the alternative is that means that if um if you didn't add the page props there what could potentially happen when the page renders is it might uh not render part of the page briefly or it might flash be signed out thing and then show you the signed in thing which I've certainly experienced on on Plenty of sites and it's definitely one of those things that feels like maybe of an era of a certain sort of uh single page web app um thing we went through and when react was young uh is that more or less what would happen without that uh yeah exactly um and and I think there's there's still some benefit like we actually have that flicker on our on our homepage right now like wait an extra second for the sign-in to run and uh or for the sign in button to display and I guess like the trade-off is there's some speed things right so if you if you don't if you don't need the auth state uh you can potentially get a page down to the user faster and um then just kind of resolve the signed in state from the client side um right as I'm saying that I'm convincing myself that that's not actually the case anymore though um yes either way either way works sure yeah I guess that's getting into the nerdy details a little bit but the reason that that's important is because like Google ranks your page based on how quickly it renders to the user and whether it shifts whether things on the page Flash and come into existence as the page loads too yeah um we found in practice granted don't look at our Lighthouse squares right now uh we've found in practice that if it's if it's just the sign up button in the upper right um and it's not triggering any layout shift then it doesn't really impact those scores um but yeah certainly you need to kill the layout shift no matter what you're doing make sure that there's space for that element to come in um right cool I have I have a more fundamental question here I guess it looks like your your next Jazz demo is using typescript uh will this all work for next projects that are just JavaScript yes yeah um it all just still goes uh yeah it's just uh I like it for the intellisense but yeah sure sure right uh yeah like it was really helpful I haven't memorized all of the elements and variables believe it or not yeah so it's great to just be able to pop it up and uh click it but everything does work with JavaScript as well very cool yeah so at this point you've added login to your page you have uh I mean you've added maybe 10 lines of code right and suddenly we have logged in logged out um experience you have some some um page content there that looks like it's loading directly from clerk2 um this user button now wow yeah yeah we've got the whole user profile here um uh we know what device we're signed in on um I can actually go into the dashboard and turn on um let's see let me turn on phone I can turn on some MFA options and then if I refresh this let's see if I I think I need to refresh some things you still need to refresh for but now users can come in they can set up qfa um yeah cool very cool so yeah so it just kind of comes out of the box um go ahead yeah I wanna I wanna sort of like emphasize what just happened there from the perspective of in a past life I I built a SAS company right uh and like the things that you've just set up and added in 12 lines of code or whatever it is it used to be like extremely arduous to do in trying and required server-side code and and you know middleware and apis and all these things uh and even then like I'm the first one to tell you that I'm not a security expert uh so there was always some element of being uncertain as to whether or not it was done correctly because there are a lot of things that can go wrong in the middle of these these processes too and so like thinking about one of these specific problems like um uh resetting your password if you forgot it uh I I can tell you I spent days making sure that I got that right building apps in the past using pretty like well-known authentication providers it was a whole whole ordeal to do for sure and so like I don't know you're it's it's a blazing demo to kind of run through pretty quickly and I just want to kind of pause and say like this is a really really interesting application and one of those things that is just like the world in 2022 feels really awesome but this used to be I don't know full-time work for a small team of Engineers for quite a few weeks to get this kind of thing done yeah yeah no thanks thanks so much for calling it out it's it's really been a ton of fun seeing how much we can build into components versus kind of the old school API approach to developer Tools in it like in your intro you're showing all the new no code stuff that Stripes doing and I think it's really all that same mindset of hey like once we actually get permission from the developer to show end users entire features instead of just like instead of just drive.charge show the checkout uh it's such a powerful concept to just keep building on and and we're really we're having a ton of fun yeah doing it doing it with auth um and it's surprising how much surface area there is I think a lot of people are kind of deceived originally by like oh yeah I pulled in this library and um I got emails and passwords going pretty quickly yeah yeah can you ask some silly future questions but sorry can I ask you some silly future questions based on being the guy who used to have to run these things so let's say I came to you and uh explained to you that I like I don't know I threw my laptop in a lake and I can no longer get to my account to reset my password uh is there a way for you to go and send me a password reset email or something like that there is a way for our for like our developer customers yeah that's what I mean yeah so so the person who owns the application can they go and like manage users from within the clerk Dev dashboard there I will say I've seen it I am not sure if it's landed on prod yet but sure sure yeah that's yeah that's um uh yeah it's coming if it's not out yeah and you had a pretty staggering amount of off providers there too which you kind of Blaze through like ticking a check box and suddenly Twitter appeared but there's what half a dozen different authenticators in there yeah and it it just it's more there's yeah that's amazing yeah wow there's a lot what's going on and it just keeps it keeps going too this one we've gotten our cycle time on this down to like two hours but now the longest part is waiting for the vendor to approve the like test application um we yeah we've got some web3 here uh if you want if you have like a new application and you have like a uh like an allow us you don't want everyone to be able to sign up yet you can get that going um sweet uh awt templates are another big one for us where um basically these tools they're all database tools um where they let you query from the front end um and if the the minimum security that they need to be able to do that is they need to know which user is signed in and so all of these companies in the documentation they publish like this is the form of JWT that you need to send me and we kind of can generate those jwts for someone so if I do if I just create like a default Sarah won I can come here and uh you know I'm just gonna do it on window but there's a there's hooks for this as well uh a token to wait it um but so this this is kind of ready in the form for uh has Sarah um to talk to Sarah graphql endpoint and so you can see it's got all these like history claims in it um and so we do that with a bunch of database vendors it's auth has become rather far-reaching I'd say um with react I think with stripe we want to do more and more um uh you know talking very specifically right you brought up redirect to checkout you moved that from the client to the server um we would love to bring it back to the client because a lot in a lot of cases what people are doing is they go to the server just so that they can pass in a stripe customer ID um in a lot of cases like not all cases but in a lot of cases like that's the only thing you're getting populated in there and since we know which user is signed in we can do that on behalf and and bring redirect to checkout back to the client so there's a lot that we're like thinking through and and kind of figuring out hey what is the best structure for a truly like modern take on off as a service because it's it's not just that login box anymore there's so much more where user state is getting shared so I guess the the next uh logical step from here or at least like the one that is in my brain from doing so much stripe stuff is like okay how do we go make the API call to create the stripe customer and then stuff that in this user model and I saw a couple different fields in the API but I was curious like what your official take is would you put that in like some metadata or I saw like an external accounts property on the user too um so like yeah yeah um so there are a couple ways to go about it um I think in practice the most common way today is that people have like a stripe customers uh table in their database and that's like a a join table so a mapping of clerk user ID to stripe customer ID um some people do store it on our user metadata um I guess I should show probably just the high level like okay you have an API endpoint how do you figure out what user is signed in um and we can do that pretty quickly here um so for all back end stuff on next.js now we actually use the new middleware and I will go to clerk docs and grab the snippet um you've done this before uh I you say that but I think we launched this like last Monday so oh wow uh we launched the new middleware approach so we've always had a way to get it from the back end um but we changed the DX a little bit and but yeah so now if I go to let's see I think next.js ships a default hello so in here if I do uh uh [Music] user ID off that didn't pop it up all right and then I pass it the request object and then we'll just pass through but we'll just return the user ID here too see is it is this a significant error to the point where it won't build I'm not actually sure okay cool um so yeah this between the middleware and the API endpoint this gets you the user ID the clerk user ID and then with that and this is all secure it uses the JWT the JWT refreshes every minute um and so uh yeah like it only takes a millisecond on the back end and you get the user's ID um if you're doing any like auditing sometimes it's also helpful to have the session ID so the session ID kind of ties a user to a device and so the session ID is there too if you want to do any like audit logging type stuff um and yeah I guess once you have this uh should I what do you think I should do should I jump into the Skype well we actually have a question from Christian here cool um and he asks on the clerk uses third-party JavaScript modal message there's a message that says redirect required and asking whether or not that message is customizable so there's no need to customize it uh it doesn't exist in production so um and it doesn't exist in Chrome and I think it won't exist anywhere before the end of the year uh basically what you're seeing there is uh everything in this demo so far has been on localhost 3000 um but where like we didn't set up any back end right like that step wasn't there the back end that's kind of powering the session State uh and managing who's logged in is on a different domain and it's actually on the uh clerk front-end API domain and that's in your environment file oh that's what that front end key thing was yeah um and so if you kind of you let's go here open up the network tab I'm gonna have to click refresh and so basically all of the off state is managed through these endpoints um so this is that that front-end API domain uh and this is how we're managing auth in development since this is a different domain than localhost 3000 we're using third-party cookies um we found a way to do it without third-party cookies but bear with us um for a couple months and just click through that on stripe and Firefox or not driving Firefox on Safari and Firefox if you actually go to prod um you look at the same API endpoints so first of all there's a lot less going on in the query string just because everything's more simplified we're using an HTTP only cookie in prod and the reason we're able to use an HTTP only cookie is because we're actually we have developers and prods set a cname um to uh yeah to our API so that's what's going on there uh you cannot customize that redirect required thing but your end users won't see it so hopefully that's okay cool um the other thing I noticed too was there were some web hooks so that's like the middleware piece and then if you wanted to be notified about different events that are firing when the maybe like when the user uses that user button and then updates something like maybe they're yeah I don't know their phone number or something and then you want to know like other phone number change because now I have to update it in my twilio connector thing or something related to that yeah yeah no that's exactly uh exactly right so [Music] um in the dashboard there's a web hook section uh we're actually using a tool called Spix to power these um which is another uh another company I'd say like on this thesis of provide entire uis to people instead of just the apis um his clerk didn't build this UI and oh wow we are grateful for them building it for us um uh yeah and so uh there's a whole bunch of things that you can subscribe to organizations we haven't covered yet um the reason why is that there's no well I'll talk about it in a second but yeah so user created deleted updated those web hooks are all there um in practice only 20 of our users turn on web Hooks and so uh the common mode of operation is to just let clerk handle your users table uh your sessions table and so on and then for any like anything that's augmenting users do it in-house but if you want they're available there for you so what I'm imagining now is like okay I'm going to set up a an endpoint inside of clerk that will let me know when a user is created or created deleted and updated and when a user is created I'm gonna make an API call to stripe to create the stripe customer and then when it comes back I'm going to store both the clerk user ID and the stripe customer ID in a database table um locally and then that's the sort of join that you're talking about right like okay exactly yeah you can either do it that way or like a just in time approach um so when a request comes in um basically here you would you know query your database see hey do I have a um a striped customer ID for this user ID yet if I don't go create one save it and then return and you can do it all just in time there is metadata on the clerk object so you could save it directly to the clerk object if you want uh but it's it's really just user preference of like got it where do they want metadata to live sure so if you don't have a database if you let's say that you wanted you wanted the clerk to be your users table basically or like your database of users then another thing that you could do is like okay when I receive the user.created event from clerk I will update that user object so they have the stripe customer ID and like plop it on the metadata for that user object and then I know like from now on it should have stripe customer ID exactly and I'm just trying to see if I can remember exactly how to do this this is what we changed got it uh let's try clerk API dot update I don't know it would be users I feel like it's my typescript is failing me um or I'm just totally having the wrong names here it wouldn't be a demo without it right I know right uh so in this part are we looking at the node SDK or are we looking at clerk like when you when you installed the next Js clerk thing did that also pull in the node SDK I think the docks here are a little uh incomplete um got it and so yeah basically it is the node SDK our node SDK and our SDK are kind of converging right now and so the docs are in a little bit of a confusing State um yeah yeah so it looks like if you pull in clerk from clerk SDK node then you can do like clerk.users Dot something yeah it should be backwards compatible so maybe I should just try that I'm gonna open up um box on a different screen here just bear with me a second sure um yeah so um while you're doing that Javier asked earlier um when do we do training in Spanish we have had one video one or two videos in Spanish on the stripe Developers YouTube channel um so if you want to head over and check those out they are pretty um out of date they're they're pretty old um but yeah if that's something that you're interested in we absolutely would love to create content in Spanish and also if that is something that you are an expert in then we would love to have you uh collaborate with us to create some some Spanish content I know that Mike going to the Dominican Republic maybe fingers crossed will make some good connections there so we can uh make some Spanish content yeah I think so tengo que practice we'll work on it I think yeah all right I think I hit a breakthrough here so it was clear client not click API then users update user pass in the user ID and then we have this public metadata um and you can either do public or private I should just add a private here cool hello is that just like the public metadata will be available on the front end with the like inside the JWT stuff that's the idea exactly so if I go to localhost now and I'm just gonna keep I should just show it in the uh in react actually so if I go to my index we can call user import it and then we'll just do div uh user this dude based on stringify it maybe what do I want here like no two yeah I should do it switch these to please there we go [Music] uh okay now the user object yeah there it is okay so here's my public metadata um and the private metadata isn't here and that's exactly for the purpose of what you're saying like all right some data you do want on the front end public cannot be changed from the front end it can only be uh set from the back end but it can be read from the front end um there is a last one called unsafe metadata um and that one you can set on the front end and uh it's for like I would only really do that for like I don't know like an analytics use case or like a quick and dirty a B test or something but if you want you can uh and save metadata uh running out of uh pillows and worlds yeah oh yeah you actually saw it up there yeah it showed up right away you didn't even have to click whoa that's cool um so yeah and so we definitely have customers that have just set the stripe ID on public metadata um and then they just they can just work with that sure very cool yeah that's a lot of stuff yeah that's a that's a pretty tidy demo uh Colin um I'm curious so um from the clerk standpoint so next is supported what other uh Frameworks are are supported yeah so uh let's check out our and then this docs here it's the easiest way to see um so as of right now we have next remix uh just straight react if you're using Straight react Redwood Gatsby and Expo um so we do work with the Expo tutorial does work with uh react native as well so if you're um yeah doing something on mobile that should work for you cool yeah so kind of anywhere you're going to be writing your react it feels like there's uh there's somewhere for a click to plug in exactly yeah I think uh I said this before the call but if people think of us as off zero for react I'll take it I think we very much have invested you know more in that ecosystem um then I I think any any other auth vendor yeah super cool so I see we're kind of getting towards the end of the hour I want to make sure uh our friends who are watching if you have any questions drop them in the chat and we'll we'll uh make sure to uh ask Colin your questions before we get off the uh stream here um Colin one question I have for you is are there features for clerk that you're excited about or that you're looking forward to uh bringing to life in the future yes organization management uh-huh that's the next big one for us so um basically everything you saw today um sign up sign in user profile and even the user button um there's the organization side of it so if you're a B2B SAS um after someone signs up the first thing they need to do is usually create an organization and then invite their team members and set their roles and permissions oftentimes they can create more than one organization and then there's a little organization switcher in the top left opposite the user button in the top right and so we're going to provide that organization switcher component we're going to provide the uis to create an organization to manage people's roles and permissions and that should be alive in November um the apis for it already exists and so when I was going through the web the web hooks you saw organizations uh reference and so that's what that's referring to apis are done we're working on the react side of it um and that's that's really the biggest you know short-term feature uh but then it's it's just more of these Integrations right like I would love if clerk you know you go in the click dashboard you do stripe connect and then we're automatically creating the stripe customer objects for every user and for every organization um because we'll have both sides of that and then we can bring that redirect to check out to the front end like that's kind of the path we're going to down is like um getting more into I had so many things are user-centric is is what I'll say um and so uh the user got charged like used to be this thing that you had in your I'm dating myself and mirror like your your rails model right your user.rb the user.charge user.email use it at all theseuser.things um user.verb uh and we're kind of trying to provide that user.rb the model as the service and taking a a broad lens to it yeah I I feel like it's easy to to glance over how staggering that amount of work is and how cool it is to be able to like plug in an app to that especially if you're building an xjs app and you have a react native mobile app and suddenly you're like on the web and on Android and on iOS and you have authentication with LinkedIn and Twitter and Google and you know you name it like across the board that's a lot of stuff that you don't have to do so you can go and build your product which is the thing that people want to use in the end anyway yeah super cool thank you thanks so much for having me this is a lot of fun absolutely yeah I didn't questions come in did not see any questions we have a request for uh some French language content um we do have some French speakers so we might be able to provide something like that Christian I'm curious kind of what topics you might want to see also if you're watching this later and you have some requests for Content or you have ideas or things that you want to learn about please let us know down in the comments below um but yeah again thanks again so much Colin really really appreciate it any uh parting parting thoughts Mike yeah Colin my last question for you is so uh assuming people have watched this tutorial and they're ready to go off and get running and start their Journey with clerk where do they go just click that dab um there's a developers tab uh if you want you can join our Discord we're pretty active in there um but yeah go to click.dev hit the docs and and get going if is really fast to get set up I think we covered a ton of ground in this hour um so yeah awesome yeah very good you can also follow at clerkdev on Twitter uh to yeah I guess we'll that's where we can stay tuned for updates exactly yeah make sure to chase down Colin also his Twitter handles on the screen at tweets by Colin uh I'm sure you'd love to field your questions about Clerk and uh CJ and I are always happy to help with stripe stuff as well absolutely all right let's call it a show thanks again so much for watching and we'll see you next time thanks Colin thank you bye friends [Music]
