Asset Pipeline - Imagemin

This is a wrapper for imagemin that will eventually become a plugin for a larger project to manage the whole build process.

It can be used however on it's own. To install run:

npm install @djforth/ap_imagemin -g

Now add the configuration details to your package.json like so (N.B. These are the defaults):

"assets": {
    "images": {
      "input": "app/assets_uncompiled/images",
      "output": "public/assets",
      "ext": [
      "plugins": [
            "interlaced": true
            "progressive": true
            "optimizationLevel": 3

These options are:

  • input - where it will look for your images
  • output - where it will place your compressed images (should not be the same as input)
  • extensions - What file extensions you wish to process
  • plugins and optimisation options see https://www.npmjs.com/browse/keyword/imageminplugin for all available plugins
