browserify-extract-ids

Browserify plugin to export a bundle's module IDs.

Installation

npm install browserify-extract-ids --save

Usage

// main.js
require('./a');
require('./b');

// a.js
require('c');

// b.js
console.log('do nothing!');

// c.js
console.log('do nothing!');

const extractIds = require('browserify-extract-ids');

browserify()
  .add('./main.js')
  .plugin(extractIds, {
    outputFile: './ids.json'
  });

This will result in a ids.json like the following. (Note: Browserify assigns modules numeric IDs.)

{
  '/some/filepath/a.js': 1,
  '/some/filepath/b.js': 2,
  '/some/filepath/c.js': 3,
  '/some/filepath/main.js': 4
}
