cjs-module-lexer
JSON →A fast CommonJS module syntax lexer that detects named exports and reexports from CJS modules, used in Node.js core for ESM interop. Current stable version: 2.2.0. Maintained by Node.js team; release cadence is irregular but active for parser bugs and performance improvements. Key differentiators: extremely fast (~90ms/MB cold, ~15ms/MB warm), frozen detection patterns to ensure backwards compatibility across Node.js versions, and support for transpiler variations (e.g., TypeScript, Babel). Provides both Node.js (CJS) and Wasm (ESM) builds, with TypeScript declarations included.
