find-imports

find-imports

Find all imported modules in JavaScript files. It's useful for bundling 3rd-party libraries into a vendor.js using webpack. For example:

var _ = require('lodash');
var webpack = require('webpack');
var findImports = require('find-imports');

var deps = _(findImports('src/**/*.{js,jsx}'))
    .toArray()
    .flatten()
    .uniq()
    .sort()
    .value();

// Webpack Configuration
module.exports = {
    entry: {
        app: [
            './src/index.js'
        ],
        vendor: deps
    },
    output: {
        path: path.join(__dirname, 'dist'),
        filename: '[name].js'
    },
    plugins: [
        new webpack.optimize.CommonsChunkPlugin('vendor', 'vendor.js')
    ]
};

Installation

npm install --save find-imports

Usage

import findImports from 'find-imports';

const files = [
    // glob pattern
    'src/**/*.{js,jsx}'
];

findImports(files);
// → { 'src/web/index.jsx':
//     [ 'lodash',
//       'async',
//       'jsuri',
//       'react',
//       'react-dom',
//       'react-router' ] }

To return absolute and relative imports:

findImports(files, {
    absoluteImports: true,
    relativeImports, true
});
// → { 'src/web/index.jsx':
//     [ 'lodash',
//       'async',
//       'jsuri',
//       'react',
//       'react-dom',
//       'react-router',
//       '/index.styl',
//       './index.css' ] }
