gulp-spritesmith

Gulp plugin for sprite generation, based on spritesmith.

Usage

First, install gulp-spritesmith as a development dependency:

npm i -D gulp-spritesmith

Then, add it to your gulpfile.js:

var spritesmith = require("gulp-spritesmith");
var gulpif = require("gulp-if");

gulp.task('sprites', function () {
    return  gulp.src('./src/**/png/*.png')
                .pipe(tasks.spritesmith({
                    imgName: 'sprite.png',
                    styleName: 'sprite.css',
                    imgPath: '../img/sprite.png'
                }))
                .pipe(gulpif('*.png', gulp.dest('./dist/img/')))
                .pipe(gulpif('*.css', gulp.dest('./dist/css/')));
});

If you need few grouped sprites, you should specify folder name to group by. Lets say you have following app structure, with several skins:

• /Module1
  • ...
  • /skin
    • /basic
      • /png
    • /green
      • /png
    • /dark
      • /png
    • /light
      • /png
• ...
• /ModuleN
  • ...
  • /skin
    • /basic
      • /png
    • /green
    • /dark
      • /png
    • /light

Then just set skin for groupBy param:

gulp.task('sprites', function () {
    return  gulp.src('./src/**/png/*.png')
                .pipe(tasks.spritesmith({
                    imgName: 'sprite.png',
                    styleName: 'sprite.css',
                    imgPath: '../img/sprite.png',
                    groupBy: 'skin'
                }))
                .pipe(gulpif('*.png', gulp.dest('./dist/img/')))
                .pipe(gulpif('*.css', gulp.dest('./dist/css/')));
});

and you`ll get 4 sprites: sprite.basic.png, sprite.green.png, sprite.dark.png, sprite.light.png. And the same for css.
