hey welcome back in this episode we're going to try to hack around with stitch which is this new uh this new platform for user infrastructure for modern applications who knows what that means it's a brand new uh brand new company they just announced a 30 million series a they've been in beta i think for a long time i was like reading through um an article i think it was on crunch base about them and i thought it might be fun to just kind of like play around with their docs read through some of their client libraries and mess around and maybe even set up a rails app where we are using stitch as our sort of authentication provider so if we head over to their docs and take a look at their example apps um they've got a few that are up um oh cool this is their popular guides also like the the people who started stitch i think were from plaid and they did like a ton of authentic like user authentication inside of plaid and so they felt really confident enough so that they left and started this company and i think a lot of the flavors of the tools the sdks the docs a lot of that definitely feels very similar to plaid which is kind of cool they have a javascript solution or they have like a server-side solution i think i don't know if we actually need to use any of the sdks or if we can just use the server um so step one is to gather information we've got some api keys in the dashboard i did sign up for an account just so that i like had an account but yep so in the test environment you have a project id and you have some secrets and then you have a public token for your sdk authentication and then you have to this this is like walking you through setting it up with stitch.js and they've got javascript they've also got react that you can use um and what i was curious about was using just using the client library solution so i was sort of expecting that i could just click on another language here i'm spoiled obviously with stripe but being able to click on another language and see the code snippet in another language would be handy for those code snippets so there's a bunch of different guides here setting up a new solution replacing password reset inviting users and i don't want to use the the frontend sdk i want to use the direct api okay cool so maybe this is going to show me nope yep still okay so it lets me copy the curl request but still no ruby code um so all right so there's a few steps here they're pretty small the first one is that we are going to build a sign up or login view why don't we just like we're gonna kick off a new rails app and say rails new stitch play dash t database is equal to postgresql and as that's spinning up we're going to build a new signup or login view so we need to have some ui that is going to have a form that collects the email address okay and we're going to say sign in with email then we're going to create a route for authentication something like example.com authenticate okay and that's where users are going to be redirected to with a token in the query string where the token is going to be um something we passed to their authentication endpoint okay step three add a magic link url to the stitch dashboard okay so we need to go to the stitch dashboard and add something send a magic link to login or create a stitch user send either a login or create magic link to the user based on the email associated and then step five is logging in the user authenticating a token so once the user clicks the magic link they're going to be redirected to that login magic link url or sign up magic link url and then you'll use the token from the url to call the authenticate endpoint log the user in and then going live you just like switch your tokens from the project like the like uh test mode test environment to live environment we're just going to like change out the keys i think all right and there are some client libraries so let's take a look at those stitch ruby very cool um so let's see how we can add this so we'll just say bundle add as soon as webpacker decides to finish here any day now webpacker any day oh wow look it okay so here's the documentation with for using the client library you pass in the environment you pass in the project id and the secret okay so we will set up a let's set up uh yeah like our credentials in the rails credentials provider and we'll set our project id and the secret in there and then we can use an initializer to set up the client i think um well i don't know because yeah maybe we want different clients for every request maybe it doesn't matter i don't know we'll just have to play around gosh webpacker is still going okay um stitch is kind of a cool name i like it s-t-y-t-c-h uh stitch it's fun i like the colors i like the design the um yeah there's just like a couple little knits that i would tighten up on the dashboard but they just launched so that they've got a lot of a lot of ways to go here i missed this it looks like you can pick the language maybe from the from the drop down at the top um it's funny we were just talking about this okay so my language of preference is ruby oh nice okay so i see all of the requests here this is the full api docs so okay so login or create user is the one that we care about i love the style here i mean again i'm pretty biased but like the colors look great it tells you the types that it's expecting and it tells you which ones are required with those stars i assume um and yeah okay that's all awesome um if we go back to all docs okay cool so from all docs it does have the drop down where you can pick your language preference and now if i go back to setting up a new auth solution with the direct api also another pattern that's really common and then here at the bottom we see now it's showing the ruby version so this is awesome oh nice they even drop in your your keys so that you can copy and paste love it love it very cool very cool um so client.magiclinks.email.login or create and we're going to pass in the email that we collect from the form and then we're going to pass in the login and sign up magic link urls to which the user will be redirected after successfully receiving their email and clicking on the link i think and then when we log the user in we are going to get a token from the request and then we're going to say authenticate and that's going to give us some response that will include the user id that's like this the stitch user id and then we can use that stitch user id to look up the user in our database and maybe cookie them i think that sounds reasonable okay cool we rails is installed so let's let's get started here so railsg model user and it's going to have a let's store like the stitch um user id and let's store i don't know the name of the user and that's probably fine i think the stitch user id is a string right because we're going to get back this user underscore or dash test dash and then some random id um so we're generate a model and then i'm going to edit the migration for this model so that we can set the stitch user id to be an index because we're going to want to like quickly look up the user when they are authenticating we're going to want to look them up really quickly with this id great so let's open up that migration and we'll make this null false add index users stitch user id unique true rake db migrate or rails db create db migrate okay it created the database and then let's say rails g controller sessions i'm going to create a sessions controller which is where i'll have like the login and the creation and all that jazz and so we'll have a new view that'll be like our login view i think and then or like our create a new session view um so that will create a new controller all right so bundle add uh stitch that will add it to our gem file that's step one okay step one is done now build a sign up or login view so let's go build that next okay so we're gonna open up the sessions new view we're working on step two to add a login view okay so we'll just say sign up or log in and we'll add a form that's going to be action is like sessions method is going to be post and we just need to collect actually i want this authenticity token thing too and we need an input and a label for the email no default value and the name is going to be email and i think sign up or log in i don't know maybe that should be fine i think i don't know let's go to our routes and make sure that we have resources sessions and now we should be able to go to localhost 3000 slash session slash new and see our form all right so now we have an email input so i'm going to put in an email address sign up or log in all right the create action could not be found for the sessions controller okay so now we need to do the next step here so step three create a route for authentication create a route that will act as your magic link endpoint users are going to be redirected there from login okay so um we need some sort of authenticate method so maybe we can make a new method here called authenticate and i don't know i don't know what we're going to do there yet but it says create a route that's going to act as your magic link users are going to be redirected from the login email it should accept a token as a query string parameter that you'll use to authenticate so token is equal to params token and we'll just say like render json of token or something i don't know and then that'll at least like spit the token back and then number four add magic link urls to the stitch dashboard so we go to the stitch dashboard here magic link urls and this is where we're sort of like white listing i think or adding to an allow list of which urls you're allowed to redirect to so we're going to create this magic link url and the type is going to be login or set as default what does that do confirm no it's not example.com it's localhost okay and then create a magiclinkurl same thing for signup i don't know what the default thing does um but maybe it's you if you don't pass something then that's the default uh so usually with like oauth flows you can potentially go to multiple places but they usually require that it's passed so we'll also use this for our invite url and we'll set that also as default okay now that is where we're gonna like redirect to so that's i think what we wanted for add magic link step five send a magic link to log in or create a stitch user so this is where we actually need to like create our client and do stuff with it so let's see if the user was created use the user id return in the response to manage the user within stitch save this user id within your user's record in your app's storage okay so let's go edit our credentials and set up our stitch project id and secret inside of our rails credentials so i'm going to set the editor to vim say rails credentials colon edit and then our secret is this thing and okay so now that we have set our project id in secret we can create a new instance of a client and i think i'm just going to do this directly in the sessions controller yeah so when we submit that form it's going to send a post request to the sessions controller which will result in calling this create action and we want to initialize the stripe or this stitch client with the project id so rails.credential dig for the stitch project id and then similarly we're gonna do the same thing with the secret rails.application.credentials dig stitch secret and that should give us a client an instance of a client and then we want to say the response is going to be client.magiclinks.email.log and the email address we want to pass is params email because that's going to be um what we're passing from the form we can actually say.params.require to sanitize the input that's like part of strong params and then the magic link url is going to be come back and hit this authenticate thing so we can just say like authenticate url and we'll need to go define that in our routes so that we can receive a get request to slash authenticate and that will go to uh sessions authenticate all right that seems reasonable and then i guess what do we do from there um i mean what do we render back like maybe we need to render back something like an email is on its way or something like that render text like email is on its way or check your email or something check your email i mean that should probably be a view that's all pretty and stuff but um let's just see if this works step six logging in a user authenticating a token so we're gonna need another client we're gonna get the token and then we're going to call client.magiclinks.authenticate so this is where we're going to call this business and then because we're using the client in both the create method and the authenticate method i'm going to extract that and make a method here we'll make it a private method private dev client and the nice thing about using a variable here and this bare word is that i can like pretty easily just move this down below and then have that be the return value and i think it should still work so the response is going to be client.magic links that authenticate with that token that we just got back from the query string params and if that worked then we want to i guess we want to like find or create the user with that id that was returned so at user equals find or like user.find or create by stitch user id and that's going to be response i guess we should call this like stitch token response or something like that stitch token just to be a little bit more explicit about what is coming back and we want to use a user id [Music] okay if and then i guess we also want to like log them in here right so um for now i think we can say like at or maybe we want to put it into the session session um current or like user id maybe user id is equal to at user.id so i was a little concerned about this flow like using like just sticking the user's id into the session because the session is managed generally it's managed with cookies it turns out that this session this special like session bag that ruby uses or that rails uses is an encrypted cookie that is also signed with your app secrets like app id when we when we edited the credentials you could see like the secret the secret base the secret key base so this session is actually encrypted and signed so you can't actually like mess with this from the client otherwise people would be able to just like use an auto incrementing id attack and just say oh i don't want to be logged in i want to be logged in as the next person who logged in after me or the person who logged in before me or whatever or who created an account before me or after me or whatever but this should this should like store the user's id in the in the session and then um for now why don't we redirect to uh slash me or something um and then we can make a new route here get slash me to sessions me and then uh def me is just gonna say render json of current user so current user is gonna be a method that we have to write in application controller and this will be based on looking up the user that was added to the database based on their stitch token so we're going to say def current user current user is going to be based on this so we're going to say user dot find by and we're going to pass in session user or we're going to say stitch user id is going to be session user id and if it finds one great if it doesn't find one then there won't be anything anyone locked in i guess we could say uh logged in there's another method here where we can say like if there's a current user then the current user is logged in it's also like helpful to have like a helper method for um current user and the logged in user so that we can use these methods from the views so hopefully this works i don't know there's like a lot you have to build here before you can test very much so i probably went a little further than i needed to but let's go back and submit the form again and oh it's missing this template render can i not do render text i thought i could just say render text uh render text test uh maybe i can just do render json of check your email um okay it says check your email do i actually get an email i don't know okay cool so i did get the email it was weird because like the the title is create your my first project oh create your myfirstproject account so i named the project my first project or something so this was confusing was that like the name of the first email i got was create you're my first like it seemed like the call to action was whack because i didn't rename my project um and then it says click the button below it's going to expire in seven days so i can click continue and that brings us where does it bring us back to rails okay we got a non-null violation error no no value in stitch user id so we were trying to pass stitch token colon user id so if i say stitch token colon user id i thought that was what okay so stitch token all right so we got a 401 we got our request id unable to auth magic link could not be authenticated and we have 401 um okay so i think we like consumed it because i clicked on it twice so let's let's go through the flow one more time but before we do i think that that authentication token might be stored as a string value so this is not actually being it's not being switched to a symbol so let's say params or stitch token that's going to be the response from this client library which right now is not symbolizing it's not symbolizing the responses so let's put in strings string string representation there and then let's go back to the flow so we're gonna go to slash session slash new and then we'll put in an email address i think we need to actually put like plus one or something like you want to add an alias every time you're testing new um new emails and you can do that with a plus and then an alias or even adding a dot in different places inside of your uh inside of the email address if you have a gmail address okay we've got another email i'm gonna click on the link to continue and we are redirected back to localhost 3000 slash me and we're getting null but we got redirected so we maybe are logged in but potentially so render json of current user so then if we go let's go look at the database so real c user.count okay so there is one user user.last okay so we have this ditch test user id um exit oh you know what okay session are we did we try using the oops at user.id so it should be oh you know what it is okay so here we're storing the id from the database and then in the application controller we were trying to look it up by the stitch id so this should just be user.find session user id because we don't we're not looking that up we're storing it in the session as the the id from the database not as the id from stitch which i think i like better in case you wanted to like switch out providers or something i don't know um all right so now if we refresh me hey look at that all right so we are authenticated and we have a current user phenomenal all right so that is how you integrate this new stitch auth flow i think it's pretty cool to have like a magic link url but i think it's also somewhat trivial to implement this same sort of system the nice things is we didn't have to set up an email service provider which if it was only for authentication like if you only need email for authentication then this is amazing this is great um the other benefit is that they are handling the um like formatting and everything of the email that's also a pain to deal with they have like a pretty legit setup for api keys so that seems pretty easy to deal with i do think that it would be amazing if they built some of this into something like into a tool like devise where they give you just like here's my stitch rails engine and you just have to mount it at a certain path and then it will automatically set up the authenticate route for you and it will automatically set up like the current user and a bunch of helpful things for you automatically out of the box to make it easy to work with for rails probably can do the same thing for laravel django a bunch of other frameworks so um but yeah first first as a first look i think this is uh pretty promising and pretty fun to play with so that is the stitch user authentication system thanks so much for watching and we'll see you next time you
