How to build a REST API with TypeScript using only native modules

TypeScript extends JavaScript by adding static types, allowing developers to catch errors at compile time rather than runtime. This tutorial outlines setting up a TypeScript environment for creating a REST API using Node.js without external libraries like Express. By utilizing TypeScript's type annotations, interfaces, and classes, developers can ensure strong typing and structure in their applications, aiding in error reduction and code maintainability. The guide includes creating a basic HTTP server and implementing CRUD operations for a to-do list stored in a JSON file, demonstrating how to handle HTTP requests and responses using native Node.js modules. While using vanilla TypeScript can lead to longer code, it provides a deeper understanding of the underlying processes and the flexibility to create standalone packages.
