basic

  • json: Loads file as JSON
  • hson: Loads HanSON file (JSON for Humans) as JSON object
  • raw: Loads raw content of a file (as utf-8)
  • val: Executes code as module and consider exports as JavaScript code

  • imports: Imports stuff to the module
  • exports: Exports stuff from the module
  • expose: Expose exports from a module to the global context
  • script: Executes a JavaScript file once in global context (like in script tag), requires are not parsed.
  • apply: Executes an exported JavaScript function, optionally with arguments, and exports its return value.
  • callback: Parses your JS, calls specified functions (which you implement in webpack context) and replaces them with the results
  • if-loader: This is a preprocesser for the webpack module bundler. It support the if directive,similar to C #ifdef .
  • ifdef-loader: Preprocessor for .js/.ts files that allows conditional compilation via // #if and // #endif, while preserving sourcemaps.
  • source-map: Extract sourceMappingURL comments from modules and offer it to webpack
  • checksum: Computes the checksum of a file
  • null: Emits an empty module.
  • substitute: Emits a module whose content is substituted (default: null, custom as parameter)

  • dsv: Loads csv/tsv files.
  • glsl: Loads glsl files and support glsl-chunks.
  • glsl-template: Loads glsl shader files. Support #include directive and template variables.
  • render-placement: Adds React.render to your component for you (not very practical in most cases)

  • node: Loads .node files that are produced using node-gyp.
  • required: Require a whole directory of trees in bulk. Require JS, Import CSS and imports stuff in it.
  • icons Generates iconfont from .svg files (uses gulp-iconfont)

  • react-proxy: Code Splitting for react components.
  • react-hot: Allows to live-edit React components while keeping them mounted and preserving their state.
  • image: Compresses your images. Ideal to use together with file or url.

  • baggage: Automatically require any resources related to the required one
  • polymer: Process HTML & CSS with preprocessor of choice and require() Web Components like first-class modules.

  • vue: Load single-file Vue.js components as modules, with loader-support for preprocessors.
  • tojson Serialize module exports as JSON. Cache generated static data as JSON at build time.
