AMD injection loader for webpack

What Is It

This is a simple webpack loader that allows you to override any dependency requested at the top of your code file in a normal define function block. It is currently very limited in scope. It doesn't handle nested require statements, and it doesn't overwrite or shim the require method itself.

If you are looking for something that works with CommonJS code, try the inject-loader.We tried that loader first, but it didn't work with AMD code and didn't work with our code formatting style, so we whipped this up to meet our immediate testing needs. The API is similar, but you don't need to specify ahead of time which dependencies you want to inject or leave alone. Simply pass in whatever injections you want each time you call the factory method. It can even change between tests in the same file.

Usage

If working with a code file that looks like this:

myfile.js

define( [ "lodash", "customApi" ], function () {
	return {
		init: function () {
			customApi.run()
		}
	}
});

You could inject a different customApi like this:

myfile.spec.js

var myfileInjector = require( "amd-inject!./myfile" );
var myfile = myfileInjector({
	customApi: {
		run: function () {
			console.log( "A new run definition" );
		}
	}
});

myfile.init(); // Outputs A new run definition

Options

To customize options, add a amdInjectLoader key to your webpack config file:

{
	loaders: [ ... ],
	...
	amdInjectLoader: {
		istanbul: true,
		stripComments: true
	}
}

• istanbul - true or false (Defaults to false) – Include istanbul ignore blocks on the lines that handle the injection
• stripComments - true or false (Defaults to false) – Strip comments from multiline dependency declarations
