Learn P5, Stripe and Xstream

### Accept payments & sell products powered by Stripe and the best of the JAMStack

There are as many ways to build an e-commerce store on the internet as there are products to sell. One thing is for certain, e-commerce is here to stay and as professional developers we need to understand how to build fully custom stores for our clients using the best modern tools available.

- React: flexible and customizable while following modern best practices
- Next.js: lightening fast with guide rails to help your project perform as consumers expect
- Stripe Checkout: lets you offload reams of complicated business logic to a trusted third party that maintains regulatory compliance, global payments, and a standard UX.

Your store will have well managed local component state using React Hooks and you'll also have clear and cohesive shared (global) state with React Context.

Finally you'll deploy your custom store to Vercel (the platform behind Next.js) as well as how to make your Next.js e-commerce store portable to deploy to other platforms.

React is one of the web’s most popular frameworks for building JavaScript applications. 

If you know what you’re doing, React can drastically simplify how you build, use, and maintain code.

Whether you’re a React newbie or you’re ready for advanced techniques, you can level-up with egghead. Explore our in-depth courses, lessons, and community resources to build more powerful applications and crack open your career.

Create an eCommerce Store with Next.js and Stripe Checkout

Payments infrastructure for the internet.

stripe

Stripe has a variety of solutions that makes it super powerful as a payment provider. We're taking advantage of their Stripe Checkout product because it allows us to get started with an online store without having to manually accept payments.

To do this though, Stripe Checkout relies on the browser to make API requests, which we have to configure to work for our website.

We will set our eCommerce site domain on Stripe's CLIENT-ONLY integration to set us up to add the checkout workflow for our site.

Next.js is a minimalistic framework for server-rendered React applications.

With Stripe or many other services, their APIs rely on special keys that authenticate requests or allow that service to track usage for things like billing.

Some of these keys are able to be used publicly and some must be kept private, but ultimately we want to have a way to easily manage these keys and not hard-code them into our application, which is where environment variables come in.

We will find our Stripe public key that will be used locally as well as in production on Vercel. You'll learn how to set an environment variable in Next.js (hint, you need to prepend `NEXT_PUBLIC` to the variable name make it available in the client) as well as in production on Vercel.

Now that we have an app and our products configure in Stripe, it's time to connect the two and give people a way to purchase our products.

Using Stripe's API, we can initiate a new instance of the Stripe Checkout flow with a simple click of a button.

We'll create an `initiateCheckout` function that handles this flow for us. After loading stripe through `@stripe/stripe-js` we'll `await` a `stripePromise` that will allow us to redirect to stripes checkout flow. You'll notice that we will need to pass in line items with the price id and quantity.

Cycle.js is a framework where your app is described as a simple function taking an event stream as input and outputting an event stream.

cycle

This lesson is the first in an introduction to Cycle.js. We will see how to build from scratch a toy version of Cycle.js. See how to use RxJS to create simple web apps, and how to separate logic from effects.

Separate Logic from Effects in Cycle.js

p5.js is a JavaScript library that starts with the original goal of Processing, to make coding accessible for artists, designers, educators, and beginners, and reinterprets this for today's web.

In this lesson we look at using color and the basic drawing methods of p5js, and how they can be combined to create a simple graphic on the canvas.
