The Book 📚

This eBook was written for software developers who are interested in learning more about TypeScript and its powerful compiler APIs. The TypeScript Compiler API is a feature-rich API available for automating code-related tasks, such as reading code, writing code, and extending TypeScript's built-in feature set.

If you want to learn how to:

  • Automate the generation of boilerplate code in your codebase.
  • Create custom linters to catch bugs and inconsistencies in your codebase faster.
  • Write more reliable code by eliminating a whole class of bugs.
  • Read and analyze code programatically to generate custom documentation or other formats of data.
  • Get a better understanding of the TypeScript internals.

Then this book is for you!

We will demystify the secrets of the TypeScript Abstract Syntax Tree and learn how to use it to our advantage! We will learn how to write linters, extend diagnostics, create custom logic for code validations at compile time, and most importantly - generate code automatically based on data and constraints.
