Build a Serverless API with Cloudflare Workers
Kristian Freeman
Kristian Freeman will teach you how to build and deploy a Serverless API with Cloudflare Workers. By learning how to build your own serverless JSON APIs, you can effectively manage a highly available backend for your projects, without needing to learn DevOps or manage services. :)
You will start by learning how to handle incoming HTTP requests so that you can work with existing clients, browsers, and mobile applications and accept data into your serverless functions.
Understanding how APIs work and how to interface with them is crucial. Traditionally, this is the realm of backend developers. That's why you will learn how to transform and return data from an API with Cloudflare Workers serving as "middleware."
Cloudflare Workers are written against a similar API to the W3C Service Workers standard. However, while Service Workers run inside the end user's browser, Cloudflare Workers run on Cloudflare's servers. This means that Cloudflare Workers can implement trusted code (which the client cannot tamper with), and will work no matter what browser the user is running. Making them potent for building APIs.
Finally, you'll come full circle and you'll use your new serverless API to build a React user interface frontend.
By the end of the course, you will be able to build a serverless JSON API from scratch using Cloudflare Workers.

Become familiar with the Workers CLI wrangler that we will use to bootstrap our Worker project. From there you'll understand how a Worker receives and returns requests/Responses. We will also build this serverless function locally for development and deploy it to a custom domain.
