Loaders

webpack enables use of loaders to preprocess files. This allows you to bundle any static resource way beyond JavaScript. You can easily write your own loaders using Node.js.

Loaders are activated by using loadername! prefixes in require() statements, or are automatically applied via regex from your webpack configuration – see configuration.

Files

• val-loader Executes code as module and consider exports as JS code
• ref-loader Create dependencies between any files manually

JSON

• cson-loader Loads and transpiles a CSON file

Transpiling

• babel-loader Loads ES2015+ code and transpiles to ES5 using Babel
