Build a global, serverless REST API with Cloudflare and Fauna` is a tutorial that guides developers through the process of creating a globally distributed, strongly consistent, next-generation serverless REST API using Cloudflare Workers and Fauna. The tutorial demonstrates how to store and retrieve data from Fauna in Cloudflare Workers functions, use the Wrangler command line interface (CLI), locally run and test a Cloudflare Workers function, and implement various REST endpoints such as GET, POST, PUT, and DELETE. Additionally, the tutorial introduces itty-router, a small and powerful router for Cloudflare Workers that can help organize codebase by isolating specific routes into separate functions. By following this tutorial, developers can create a production-ready application that serves data quickly and accurately to a worldwide audience.
