Node.js + TypeScript Setup

Summary

Configuring a Node.js project to write, compile and run TypeScript — `tsconfig.json`, build scripts, and choosing between compiling ahead-of-time or running directly.

How to Learn This

  • 1Set up a fresh Node project with TypeScript from scratch, including `tsconfig.json`.
  • 2Configure a `build` script that compiles TS to JS for production.
  • 3Learn the key `tsconfig.json` options: `strict`, `target`, `module`, `outDir`.
