CommonJS Module Analyzer

Build a tool that analyzes CommonJS module source code and reports on the module's exported names and any module reexports it contains.

Requirements

Your tool should provide a function that:

1. Accepts JavaScript source code as a string input
2. Analyzes the source code to extract information about exports
3. Returns an object containing:
   • An array of named export identifiers found in the module
   • An array of module specifiers that are being reexported (e.g., from patterns like module.exports = require('./other'))

The tool should handle various CommonJS export patterns including:

• Direct property assignments: exports.foo = ...
• Module.exports assignments: module.exports.bar = ...
• Object literal exports: module.exports = { a, b, c }
• Reexport patterns: module.exports = require('./another-module')

Test Cases

• Given source code "exports.foo = 'bar';", the function returns { exports: ['foo'], reexports: [] } @test
• Given source code "module.exports = { a: 1, b: 2 };", the function returns an object with exports containing 'a' and 'b' @test
• Given source code "module.exports = require('./other');", the function returns an object with reexports containing './other' @test
• Given invalid JavaScript source code (syntax errors), the function handles the error gracefully @test

API

/**
 * Analyzes CommonJS module source code and extracts export information
 * @param {string} sourceCode - The JavaScript source code to analyze
 * @returns {Promise<{exports: string[], reexports: string[]}>} Object containing arrays of exports and reexports
 */
async function analyzeModule(sourceCode) {
  // Implementation here
}

module.exports = { analyzeModule };
