AST Transpiler

ast-transpiler is a versatile source-to-source transpiler that converts code between JavaScript, TypeScript, Python, and PHP by operating on abstract syntax trees. Version 0.0.85, under active development, it provides a unified AST representation and supports transpilation of modern JavaScript (ESM/CJS) to multiple target languages. Key differentiators: single-pass transpilation, TypeScript-first with full type definitions, and extensible transpilation rules. Ideal for multi-language codebases and tooling that requires cross-language code generation.
