Bundle Loader

Bundle loader for webpack.

Install

npm i bundle-loader --save

Usage

// The chunk is requested, when you require the bundle
var waitForChunk = require("bundle-loader!./file.js");

// To wait until the chunk is available (and get the exports)
//  you need to async wait for it.
waitForChunk(function(file) {
	// use file like it was required with
	// var file = require("./file.js");
});
// wraps the require in a require.ensure block

// Multiple callbacks can be added. They will be executed in the order of addition. 
waitForChunk(callbackTwo);
waitForChunk(callbackThree);
// If a callback is added after dependencies were loaded, it will be called immediately.

The file is requested when you require the bundle loader. If you want it to request it lazy, use:

var load = require("bundle-loader?lazy!./file.js");

// The chunk is not requested until you call the load function
load(function(file) {

});

name query parameter

You may set name for a bundle using the name query parameter. See documentation.

Note chunks created by the loader will be named according to the output.chunkFilename rule, which defaults to [id].[name]. Here [name] corresponds to the chunk name set in the name query parameter.

Example:

require("bundle-loader?lazy&name=my-chunk!./file.js");
require("bundle-loader?lazy&name=[name]!./file.js");

And the webpack configuration:

module.exports = {
   entry: { ... },
   output : {
      path : ...,
      filename : '[name].js',
      chunkFilename : '[name]-[id].js', // or whatever other format you want.
   },
}

Normal chunks will show up using the filename rule above, and be named according to their chunkname. Chunks from bundle-loader, however will load using the chunkFilename rule, so the example files will produce my-chunk-1.js and file-2.js respectively.

You can also use chunkFilename to add hash values to the filename, since putting [hash] in the bundle query parameter does not work correctly.
