Jason Rametta is a software engineer and TypeScript educator focused on the unusually-deep niche of the TypeScript Compiler API — the programmatic interface for tools that work with TypeScript ASTs (linters, codemods, language servers, build tools).
His CourseFlix listing carries The TypeScript Compiler API Book — the canonical paid resource on the TypeScript Compiler API, covering AST traversal, the type-checker programmatic interface, building custom transformers, and the patterns for writing tools that operate on TypeScript at the compiler level.
Material is paid and aimed at advanced TypeScript developers building tools rather than applications. For broader content, see CourseFlix's TypeScript category page.
