in a remix application remix is relatively new it's a very exciting framework and there's a couple different things with loaders and actions that are part of remix that i want to show you about how to get started with stripe [Music] from the terminal i'm going to run npx create remix at latest so i'm running the latest version of the create remix installer and we're just going to get started with the very bare bones basics let's call this a remix stripe application and we're going to use just the basics not a pre-configured stack ready for production we're going to use the remix app server and sure we'll use typescript today and yeah we'll allow remix to npm install everything for us while that's loading let's head over to the stripe dashboard and grab our api keys so from the stripe dashboard we can head over to the developers tab go to the api key section and here we'll see our publishable key and secret key for now let's just grab our secret key jump into our remix stripe application and open up a new dot n file where we're going to say stripe secret key is equal to our secret key we're going to install the publishable key on the client at this point we can start up our application by saying npm run dev that'll run remix dev and start up a dev server which will load our environment variables which is pretty convenient at this point we have an application that we should be able to pull up here so we can go to localhost 3000 and we have the boilerplate for remix next we're going to install some client libraries so on the server side we're going to use the stripe node sdk in order to make api calls server-side api calls to stripe to create payment intents and also to work with web hooks then on the client side we're going to want to install stripe.js and react stripe.js which are wrappers for the stripe.js client library so we're gonna say npm add stripe and we're also gonna say at stripe stripe js and at stripe react stripe js all right let's open this up and take a look at the boilerplate that we have here so in root.tsx this is the application that this is kind of like the application structure that remix gives us we could just change our title here to remix stripe and we'll see that the title on the page uh updates we can't really see it because we have too many tabs open here but now we will see that this this title re updated to remix stripe the next thing we want to do is jump into our routes we have one index route right now and this is where all of our boilerplate lives so let's change the the header to remix stripe and we should see that change here on the right side you'll notice that it's like also sort of auto loading for us which is pretty convenient for now we're just going to remove all of those list items and add a single link that's going to go to slash pay we're going to say maybe buy a book or something okay and so now we have this link to buy a book but when we click on that link there is no pay rep the really nice thing about remix is you can just add a new route by adding a file to a directory so we're going to add pay.tsx here and inside here we need to export default and then some function that is going to be the pay component that is rendered on this page we're going to return some jsx just like we would from any react component and maybe we'll just say that this is an h1 that says pay okay and when we refresh the page over here we should see now that we have an h1 with pay on it so there's a couple different things that we need to do in order to get stripe up and running on the client the first is that we want to wrap a section of a payment form with an elements provider the elements provider is where we can give the stripe.js object that has the api key and all of the api methods for stripe.js that's going to look something like this let's give ourselves a little container here and we'll add the elements provider now inside of the elements provider we're going to have some children and we'll add those in just a minute so we're going to import elements from stripe react stripe js so the elements provider comes from react stripe.js now if we refresh the page here we have an invalid prop type of stripe supplied to elements and that's because this elements uh this elements component expects that we're receiving a stripe prop that is either a stripe.js object or a stripe promise so we're going to pass in a stripe promise here so we're going to say const stripe promise is load stripe and we need to pass in our api key here this is going to be our publishable api key again we can grab this from the stripe dashboard in the same section as we found the other api key and this should load stripe.js for us now this load stripe function comes from the npm module for stripe.js so we're going to import load stripe from at stripe stripe js uh then we need to pass this in to our prop for the elements we're gonna say stripe promise and now we have the elements provider should be wired up as expected so we just see children here because i actually literally wrote children that's because we want to use another feature of we want to use a feature of remix called an outlet so we're going to import outlet from remix and we're going to use that here as our children now the thing about an outlet is that we need some other thing to render inside of this outlet so the way that an outlet works it's sort of like we're creating sort of a hierarchy at this route so right now when you hit the pay route we're rendering this tsx component but we can also add a pay directory and inside of the pay directory we can add index dot tsx and this will be a component that's rendered sort of as the children inside of that outlet or it's rendered at that outlet so we can say export default function index and again we're going to say render or return for now we'll just return an empty string just to get this rendering properly so now we have let's say this is like inside the outlet all right now because we're on the pay just slash pay it knows to use the index route let's add another subroute that is nested inside of pay so we can say success.ts and this will create another component that will be rendered when we go to the route pay slash success now we can see that it's changing the the content on the page is changing to show the word success so if we're at the root or like slash pay that's kind of like the root of that pay route it shows that we're inside the outlet otherwise we're going to go show that we're inside of success so that's kind of how that outlet works now the other thing that we want to do is inside of the index here is we actually want to render a form and that form is going to be the payment form where we're going to accept payment for this item that we're going to sell and so remix has another really handy component called a form component so we can import a form from remix and now we can say give me a form component that has an action of i don't know uh you know pay and it has a method of post and this form component can now have a button inside of it that says pay and here we can also render other components other sub components if we want so if we wanted to here we could collect i don't know like we could have an input a label maybe for name and an input of type text name name so this is how we could collect some details from the customer and when we click on this submit button it would just send a raw post request using the built-in browser's api back to the server and then inside of uh inside of remix we could use an action in order to respond to that but what we're going to do today is just a little bit different we're actually going to listen for this the click on the form the same way we would with the typical react application because we want to capture that submission and use stripe.js in order to submit the payment now before we need before we can do that what we want to do is render a payment element into the form we're going to pass in uh the payment element component and this is a component that will render a bunch of different payment method types now the payment element here we need to uh we need to import from at stripe react stripe js the other thing that we need to do is in order to use a payment element we need to uh pass in options into the elements provider with some payment intent information so at this point what we need to do is create this thing called a payment intent we're going to create that on the server side and a payment intent is the intent to move money this is kind of like the object that is going to track the life cycle or the state machine for a payment so is the payment you know pending is it processing is it failed does it need any other further actions like for instance verifying the the bank account details that are related to the payment or does it need to have some authentication that happens and so in order to do that we need to have some sort of server side method that it's going to make an api call to stripe to create a payment intent to keep things organized i'm going to create a file here called payments.ts and this will contain all of our api calls to stripe so i'm going to import stripe from stripe and this time i'm importing this stripe constant from the stripe node client library and we're working on the server now so now i can say like const stripe is a new stripe and i'm going to pass in my secret key this time process.n dot stripe secret key and now that i have a stripe constant i can create a function that's called create payment intent here i'm going to create a function that we're going to export it's going to be an async function called create payment intent it doesn't take in any arguments this is where we're going to call stripe.payment intents dot create and we're going to pass in what we want to accept payment for so the amount is going to be i don't know let's say 20 and the currency is usd that amount value is in the lowest denomination possible so that's in cents for usd and then we also need to specify some payment method types in this case we can enable automatic payment methods and this will make it so that my payment methods render based on my configuration in the dashboard so i'm going to say enabled is true at this point we are making we can make an api call to stripe to create a payment intent and so what we want to do is we want to return that result stripe payment intents create will return a promise so we want to await that promise and then we'll go back to our to our pay function here and say we want to define this new thing called a loader so we're going to say export const loader is a new function and inside of this function we will create the payment intent so here we're going to say return await create payment intent let's go import that function that we just created over in payments ts import create payment intent from payments okay so the loader is really kind of like the server side function that's going to execute that you can use to sort of render stuff that you need from the server directly into your react component server side before it's i don't know before it's sort of like i guess hydrated you might say so the way that this works is there's another uh there's a hook that's available inside of remix called use loader data and so we're gonna use that in order to grab our payment intent that was just created so we can say payment intent is use loader data and now what we can do is pass in an options block to our elements provider and that options block is going to contain a client secret it's going to be an object that has a client secret property from the payment intent dot client secret that's underscore okay so what have we got now so we have this elements provider that we're initializing passing in stripe we're also passing in options and we're using the loader data that is creating a payment intent on the server with our server-side api call let's take a look at our logs here and see what's failing a weight can only be used inside of an async function so we need to make our loader async process is not defined i must have misspelled that okay so now we have a payment form that is rendering with the payment element this is fantastic so this is the payment element um it supports several different payment methods again these are all just enabled directly through the dashboard and so now if i wanted to i could say enter in some some card details here and when i click pay right now it's just making a post request directly back to the server and it's attempting to call an action but that action is not actually defined but in fact what we want to do is we don't actually want to make this make this post request back to the server just yet instead what we want to do is handle the payment client side and so what we're going to do is add a a instead of having an action here or a method we're going to say on submit we want to handle submit so we're going to say handle submit and the reason we want to do this is because we need to confirm the payment client side with stripe.js so handle submit we're going to initially prevent default and that's going to make sure that we don't actually do that full page submission at least initially the next thing we want to do is confirm that payment so we can say stripe.confirm payment and this takes in a few different options first is a reference to the elements object the second is some confirm params which will have a return url in this case we're just going to hard code http localhost 3000 slash pay success so where did this elements thing actually come from well inside of react stripe js there's a hook called use elements and when we are in a component that's nested inside that elements provider we can say const elements is use elements that can make it super super handy okay the other thing that we're using here is we're referring to stripe but we don't actually have any reference of stripe right here and so there's another hook that's available as part of rx drive.js called use stripe and this again will grab reference to that stripe object that is given to us through that elements provider so now we can say cons stripe is use stripe and at this point we are ready to sort of just await this promise for confirming the payment intent so if we refresh the page here now we'll see that if we enter in some card details when we click pay it will actually confirm the payment and redirect us to this slash pay success page now in the query string param it's kind of hard to see here but you have the id of the payment intent and the client secret for the payment intent which is really nice because we can use those to render some statuses about the payment here we can render some more details about the payment so at this point what you might want to do is actually inside of remix there's another tool you can use called use submit and this can be really handy when you need to handle a little bit of client-side code and then also still submit back to some action so here you might say something like const submit is use submit and then after your payment is confirmed in the case that you didn't actually naturally sort of redirect you could say return submit and you can pass in e dot current target and that would submit the form the same way that you that you would even if you were not handling this client-side confirmation because we are handling client-side confirmation and we are automatically redirecting to that page after confirmation then this doesn't really do anything for us at this point so we can remove that and head over to our success page and just talk a little bit about how we might handle this so inside of our success page what we want to do is maybe render out some content about that payment intent now with remix we actually have a couple different options so we could either grab the payment intent on the client side and render that out because we have access to retrieve payment intent this is one of the very few things that you can retrieve client side with a publishable key with react stripe.js alternatively what we can do is add a loader here another loader that would make an api call server side to retrieve the payment intent and that's what i think i want to do is say const loader is another async function and this time what we want to do is take in the request and use what's on the request in this case the query string parameter in order to make a call back to stripe to retrieve the payment intent we need to pull that that payment intents id off of the request so how do we do that well we can say cons url is new url based on the request.url next what we can do is say the payment or the id of the payment intent is url.searchparams.getpayment intent and then we want to say something like return await retrieve payment intent which we haven't defined yet and that should retur return from our loader data the payment intent that we retrieve so let's head back over to payments and add another function here that will retrieve a payment intent so in this case we're going to take in a the id of the payment intent and we're going to retrieve it based on its id and we're just going to return that so now if we come over here we should be able to import that new function into our success page and that will retrieve the payment intent now again we need to import uh use loader data from remix so that we can use that loader data in our rendering that were or in our view that we're about to render so const payment intent is use loader data and now we can build out a little view here that might say like thank you for your payment and then we could render out some pre-tag perhaps with our payment intent and let's see how that looks all right thank you for your payment and then here is all the json data that came back for that payment intent so there's tons that we could do with this and obviously you would want to display something like here's how much you paid this is when you can expect your goods to be shipped to you etc so at this point you should be all set to go to build out a a very basic remix app that can accept a one-time payment in a future episode we're gonna go over how to build a web hook handler using remix thanks so much for watching and we'll see in the next one --- [Back to all videos](https://www.cjav.dev/videos) --- ## Hey Agent, thanks for visiting!
