• 

The Rust crate oxc_parser is production ready.

• 3x faster than swc parser (benchmark).
• Parses .js(x) and .ts(x).
• Passes all parser tests from Test262 and 99% from Babel and TypeScript.
• Utility for extracting ESM import and export data - a better es-module-lexer.
• ✅ works with checker.ts

Installation

Rust

Use the umbrella crate oxc or the individual oxc_ast and oxc_parser crates.

Rust usage example can be found here.

Node.js (NAPI)

Try the experimental node binding oxc-parser.

This package does not have an AST visitor nor TypeScript typings for the AST yet.

ESM Module Lexer

• Use the npm package oxc-parser with the API moduleLexerSync.
• Use the crate oxc_module_lexer.
