externalize-relative-module-loader

undefined

This loader aims to solve cases where a library makes an import from a specific file:

import map from 'lodash/map';

and app (that uses that lib) strives to put this dependency in its externals.

Install

npm install --save externalize-relative-module-loader

Usage

module.exports = {
  module: {
    rules: [
      {
        test: path.resolve('node_modules/lodash'),
        use: {
          loader: 'externalize-relative-module-loader'
        }
      }
    ]
  }
}

Assumptions

• Bundle is a library (usage of output.libraryTarget).
• Dep is included in externals.
• Dep has the same exported property like the name of the imported file (for instance, map is the intended property in lodash/map).
• Imported file is .js file - this one can be solved, PR is welcomed.
