gulp-spritesmash

Versions your static assests based on their content and updates all references to them in other passed files.

sprite.png → sprite-e59ace00a5.png

sprite.css

  .icon-sprite1 {
    background-image: url(sprite-e59ace00a5.png);
    background-position: 0px 0px;
    width: 32px;
    height: 32px;
  }

This was written because spritesmith generates a new image and new css from the input images. Spritesmash will take each image hash the contents and update the name and replace all usages in the given file types allowing the sprite image to be busted if it has changed.

Install

$ npm install --save-dev gulp-spritesmash

Usage

var gulp = require('gulp');
var spritesmith = require('gulp.spritesmith');
var buffer = require('gulp-buffer');
var spritesmash = require('gulp-spritesmash');

gulp.task('default', function () {
	return gulp.src('src/images/*.{png}')
    .pipe(spritesmith({
      imgName: 'sprite.png',
      cssName: 'sprite.css',
    }))
    .pipe(spritesmash())
    .pipe(gulp.dest('dist'));
});
