bare-module-lexer

bare-module-lexer

Heuristic lexer for detecting imports and exports in JavaScript modules. It trades off correctness for performance, aiming to reliably support the most common import and export patterns with as little overhead as possible.

Usage

const lex = require('bare-module-lexer')

lex(`
  const foo = require('./foo.js')
  exports.bar = 42
`)

// {
//   imports: [
//     { specifier: './foo.js', type: REQUIRE, names: [], position: [ 15, 24, 32 ] }
//   ],
//   exports: [
//     { name: 'bar', position: [ 37, 45, 48 ] }
//   ]
// }
