guetzli wrapper that makes it seamlessly available as a local dependency

guetzli-bin

Guetzli is a JPEG encoder that aims for excellent compression density at high visual quality. Guetzli-generated images are typically 20-30% smaller than images of equivalent quality generated by libjpeg.

You probably want imagemin-guetzli instead.

Install

$ npm install guetzli

Downloading From a Custom Source

By default, this package will download guetzli from GitHub. To use a custom source, set the npm config property imagemin_local_url. The downloader will append /<name>/<version>/vendor/<dist>.

$ npm install guetzli --imagemin_local_url=https://mymirror.local/path

Or add property into your .npmrc file(https://docs.npmjs.com/files/npmrc)

imagemin_local_url=https://mymirror.local/path

Another option is to use the environment variable IMAGEMIN_LOCAL_URL.

$ IMAGEMIN_LOCAL_URL=https://mymirror.local/path npm install guetzli

Usage

const {execFile} = require('child_process');
const guetzli = require('guetzli');

execFile(guetzli, ['input.jpg', 'output.jpg'], error => {
	console.log('Image minified!');
});

CLI

$ npm install --global guetzli

$ guetzli --help
