Not to be confused with d-fischer's twitch.js which is now called twurple

I'll be using twurple for integration with Twitch APIs, but that's for later.

Now that we’ve created our Stream Online subscription, the next step is to send it to Courier, which we’ll use to create and deliver notifications about our Twitch stream. To do this, we need to add a call to Courier's Send API when a stream.online event comes in. We'll use the Courier Node.js SDK to do this. We'll also use the Twitch.js library to query the Twitch API to grab more details about the stream that we can send to Courier.

Express: A lightweight framework for building web applications.

Now, we will create API using expressjs. When we created application using --ssr flag, the Angular CLI already took care of installing expressjs for us.

First, we import express. The Express framework allows us to create routes that will respond to webhook POST requests and serve an HTML file when a GET request is made to the root of the site.

Starting off strong with Express.js, the cool kid on the block for building web apps. It's lightweight, flexible, and doesn't throw a tantrum when you ask it to scale. With Express, you can handle HTTP requests like a pro, play around with middleware, set up routes without breaking a sweat, and render views that make your app look stunning. Big names like Netflix and Uber are already on board, and if it's good enough for them, it's definitely worth a peek.
