This example combines Code Splitting and Loaders. Make sure you have read the documentation of the examples that show the feature alone.
The bundle loader is used to create a wrapper module for file.js that loads this module on demand. The wrapper module returns a function that can be called to asynchronously receive the inner module.
example.js
require("bundle-loader!./file.js")(function(fileJsExports) {
console.log(fileJsExports);
});

module.exports = "It works";
