Image loader module for webpack
Minify PNG, JPEG, GIF, SVG and WEBP images with imagemin
Issues with the output should be reported on the imagemin issue tracker.
$ npm install image-webpack-loader --save-dev
Installing on some versions of OSX may raise errors with a missing libpng dependency:
Module build failed: Error: dyld: Library not loaded: /usr/local/opt/libpng/lib/libpng16.16.dylib
This can be remedied by installing the newest version of libpng with homebrew:
brew install libpng
webpack.config.js, add the image-loader, chained after the file-loader:
rules:test: /\.$/iuse:'file-loader'loader: 'image-webpack-loader'options:bypassOnDebug: true // email@example.com: true // firstname.lastname@example.org and newer
For each optimizer you wish to configure, specify the corresponding key in options:
rules:test: /\.$/iuse:'file-loader'loader: 'image-webpack-loader'options:mozjpeg:progressive: true// optipng.enabled: false will disable optipngoptipng:enabled: falsepngquant:quality: 065 090speed: 4gifsicle:interlaced: false// the webp option will enable WEBPwebp:quality: 75
Comes bundled with the following optimizers, which are automatically enabled by default:
- mozjpeg — Compress JPEG images
- optipng — Compress PNG images
- pngquant — Compress PNG images
- svgo — Compress SVG images
- gifsicle — Compress GIF images
And optional optimizers:
- webp — Compress JPG & PNG images into WEBP
Each optimizers can be disabled by specifying
optimizer.enabled: false, and optional ones can be enabled by simply putting them in the options
If you are using Webpack 1, take a look at the old docs (or consider upgrading).
Using this, no processing is done when webpack 'debug' mode is used and the loader acts as a regular file-loader. Use this to speed up initial and, to a lesser extent, subsequent compilations while developing or using webpack-dev-server. Normal builds are processed normally, outputting optimized files.
Same functionality as bypassOnDebug option, but doesn't depend on webpack debug mode, which was deprecated in 2.x. Basically you want to use this option if you're running email@example.com or newer.
For optimizer options, an up-to-date and exhaustive list is available on each optimizer repository:
