gulp-zopfli

a Zopfli plugin for gulp, based on node-zopfli.

Install

npm install --save-dev gulp-zopfli

Options

You can pass an options array to the zopfli object. These options are passed on to node-zopfli library, except for one: the format options is used to pick a compression format. The possible formats are: "deflate", "zlib" or "gzip".

The defaults options are:

{
    format: "gzip",
    verbose: false,
    verbose_more: false,
    numiterations: 15,
    blocksplitting: true,
    blocksplittinglast: false,
    blocksplittingmax: 15
};

Examples

var gulp = require("gulp");
var zopfli = require("gulp-zopfli");

gulp.task("compress", function() {
	gulp.src("./dev/scripts/*.js")
	.pipe(zopfli())
	.pipe(gulp.dest("./public/scripts"));
});

gulp.task("default", function() {
  gulp.run("compress");
});

Since the plugin is based largely on it, if you're already using gulp-gzip, switching to zopfli should be as easy as replacing

var gzip = require("gulp-gzip");

by

var gzip = require("gulp-zopfli");

Credit

This plugin was based largely on gulp-gzip, I basically just replaced gzip by zopfli so all credit is due to Jeremy.
