gulp-svgmin

Minify SVG files with gulp.

gulp-svgmin

Minify SVG with SVGO.

If you have any difficulties with the output of this plugin, please use the SVGO tracker.

With npm do:

npm install gulp-svgmin --save-dev
var gulp = require('gulp');
var svgmin = require('gulp-svgmin');
 
gulp.task('default', function () {
    return gulp.src('logo.svg')
        .pipe(svgmin())
        .pipe(gulp.dest('./out'));
});

Optionally, you can customise the output by specifying the plugins option. You will need to provide the config in comma separated objects, like the example below. Note that you can either disable the plugin by setting it to false, or pass different options to change the default behaviour.

gulp.task('default', function () {
    return gulp.src('logo.svg')
        .pipe(svgmin({
            plugins: [{
                removeDoctype: false
            }, {
                removeComments: false
            }, {
                cleanupNumericValues: {
                    floatPrecision: 2
                }
            }, {
                convertColors: {
                    names2hex: false,
                    rgb2hex: false
                }
            }]
        }))
        .pipe(gulp.dest('./out'));
});

You can view the full list of plugins here.

You can also use gulp-svgmin to optimise your SVG but render a pretty output, instead of the default where all extraneous whitespace is removed:

gulp.task('pretty', function () {
    return gulp.src('logo.svg')
        .pipe(svgmin({
            js2svg: {
                pretty: true
            }
        }))
        .pipe(gulp.dest('./out'))
});

To have per-file options, pass a function, that receives file object and returns svgo options. For example, if you need to prefix ids with filenames to make them unique before combining svgs with gulp-svgstore:

gulp.task('default', function () {
    return gulp.src('src/*.svg')
        .pipe(svgmin(function getOptions (file) {
            var prefix = path.basename(file.relative, path.extname(file.relative));
            return {
                plugins: [{
                    cleanupIDs: {
                        prefix: prefix + '-',
                        minify: true
                    }
                }]
            }
        }))
        .pipe(svgstore())
        .pipe(gulp.dest('./dest'));
});

Pull requests are welcome. If you add functionality, then please add unit tests to cover it.
