Jason Rametta's book takes you inside the TypeScript Compiler API — the machinery TypeScript itself uses to parse, analyze, and generate code — so you can put it to work on your own tooling.
What you can do with it
- Automate generation of boilerplate code in a project
- Build your own linters for faster debugging
- Catch whole categories of bugs before they ship
- Analyze code programmatically to generate documentation or other output
- Understand how TypeScript actually works under the hood
It's aimed at developers who want to go deeper with TypeScript, engineers automating code-related tasks, and software architects trying to make a codebase more reliable — delivered as an HTML book you download as an archive.
