babel-plugin-dynamic-import-webpack

Usage

Via .babelrc (Recommended)

.babelrc

{
  "plugins": ["dynamic-import-webpack"]
}

Via CLI

$ babel --plugins dynamic-import-webpack script.js

Via Node API

require("babel-core").transform("code", {
  plugins: ["dynamic-import-webpack"]
});

Dynamic imports and webpack

Although the specification for import() supports a dynamic importing of modules in the browser runtime, webpack's require.ensure() is not dynamic and requires a hardcoded string to work correctly. For more information see webpack's documentation on dynamic imports.
