A Broccoli plugin for converting JPEG/PNG images to WebP.

broccoli-webp

This Broccoli plugin converts JPEG/PNG files to WebP.

Installation

Install just like any other broccoli plugin:

npm install --save-dev broccoli-webp

cwebp-bin is listed as an optional dependency.
If you can't install it, install cwebp manually:

• FreeBSD: pkg install graphics/webp
• OS X: brew install webp
• Ubuntu/Debian: sudo apt-get install webp

Usage

var Webp = require('broccoli-webp')

var outputNode = new Webp(inputNode, options)

• inputNode: A node (tree) that contains the images you want to convert.
• options: A hash of options. Currently supported:
  • quality (number, 0..100): compression quality for JPEGs (PNGs are converted to lossless WebP)
  • alphaQuality (number, 0..100): transparency quality
  • compression (number, 0 -- fast, 6 -- slowest): compression strength

Example

var Webp = require('broccoli-webp')

var img = 'img'

var webp = new Webp(img, {quality: 80})

return [img, webp]
