gulp-inline-svg

inline-svg plugin for gulp

This plugin takes a couple of SVG files and provides them inside a Sass mixin as inlined background-images. By doing so, you can use them without having to touch your markup.

Compatibility

The inlined SVG gets URL encoded, so it's safe to use starting with IE9.

Important notes

The generated mixin contains width and height values for each SVG. Those values are taken from the width and height attribute inside the SVG. If it does not provide them, they will be set to 0px. You can still overwrite them in your CSS.

Usage

First, install gulp-inline-svg as a development dependency:

npm install --save-dev gulp-inline-svg

Then, add it to your gulpfile.js. I'd recommend to use it in conjunction with gulp-svgmin to clean the SVG before inlining them.

var inlineSvg = require("gulp-inline-svg"),
    svgMin = require('gulp-svgmin');
 
gulp.task('inline-svg', function() {
    return gulp.src("images/svgs/**/*.svg")
        .pipe(svgMin())
        .pipe(inlineSvg())
        .pipe(gulp.dest("sass"));
});

This will create a _svg.scss file inside your 'sass' folder.

Usage inside you Sass code

The _svg.scss file will provide you with the following mixins and functions:

inline-svg mixin

.my-icon {
    // will set the svg as background-image and width/height 
    @include inline-svg($icon-name);
}

inline-svg-width function

.my-icon {
    margin-left: inline-svg-width($icon-name);
}

inline-svg-height function

.my-icon {
    margin-bottom: inline-svg-height($icon-name);
}

Configuration

If you want to customize the default configuration, you can pass an options object to the task function:

gulp.src("images/svgs/**/*.svg")
    .pipe(svgMin())
    .pipe(inlineSvg({
        filename: '_svg-file.scss',
        template: 'mytemplate.mustache'
    }))
    .pipe(gulp.dest("sass"));

filename

Specifies the name of the generated file.

template

The plugin will generate an .scss-file by default, but you can easily adopt this for other languages, by using your own template. With this option, you can specify the path to a mustache template.

You can use the default template as a blueprint to create your own. And please don't hesitate to share your template if you create one for an additional language.
