TypeScript Codemod Examples

This repository contains a basic sample codebase dealing with brewing coffee. This codebase can then be audited and codemodded:

• yarn run audit - executes audit.ts
• yarn codemod - executes transform.ts

This code audit and codemod are written in TypeScript to take advantage of the type-safety. Particularly, making sure the AST node properties are properly narrowed by it's type to prevent runtime errors.

This is the complete code used in the blog post covering this in more depth: https://skovy.dev/codemod-workflow
