Using webpack, what is the simplest way to bundle an JS files from an array of paths?

Here’s how to bundle JS files from an array of paths in webpack:

1. Leverage the entry property:

Webpack allows defining the entry points for bundling. You can achieve this using an array:

JavaScript
const path = require('path');

module.exports = {
  entry: [
    path.resolve(__dirname, 'src/file1.js'),
    path.resolve(__dirname, 'src/file2.js'),
    // Add more paths to your JS files here
  ],
  // ... other configurations
};

This approach explicitly defines each entry point.

2. Utilize dynamic entry points (alternative):

For a more dynamic solution, you can use a function within the entry property:

JavaScript
const path = require('path');

module.exports = {
  entry: () => {
    const entries = [
      path.resolve(__dirname, 'src/file1.js'),
      path.resolve(__dirname, 'src/file2.js'),
      // ...
    ];
    return entries.map(filePath => ({
      // You can customize the name for each bundle here (optional)
      name: '[name]',
      path: filePath
    }));
  },
  // ... other configurations
};

This function creates an object array defining entry points with paths and optional names.

Explanation:

  • path.resolve(__dirname, 'path/to/file.js'): This resolves the absolute path to your JS files using the path module (built-in with Node.js).
  • In both methods, replace 'src/file1.js' and 'src/file2.js' with the actual paths to your JS files.
  • The output configuration (not shown here) defines where the bundled file(s) will be placed.

Additional points:

  • This approach bundles each file into a separate chunk by default.
  • You can configure further bundling behavior using loaders, plugins, and other webpack options.
