Do You Want to Build a Build Tool?
summary
Shows concrete, runnable steps: read source files with Node fs and path, parse into ASTs (esprima / the TypeScript compiler APIs suggestion), query with esquery, generate snippets with es-template and emit code with escodegen, then write files back so every doPhysics call becomes doMagic and a new doMagic function is injected. Demonstrates parsing, pattern-matching, AST-level insertion and codegen end to end, with working file I/O and examples rather than vague promises.
