Oxc Module Lexer

This is not a lexer. The name "lexer" is used for easier recognition.

es-module-lexer

Outputs the list of exports and locations of import specifiers, including dynamic import and import meta handling.

Does not have any limitations mentioned in es-module-lexer.

• get imported variables https://github.com/guybedford/es-module-lexer/issues/163

Benchmark

This is 2 times slower than es-module-lexer, but will be significantly faster when TypeScript is processed.

The difference is around 10ms vs 20ms on a large file (700k).
