extract-svg-styles

Extract <style> definitions from an SVG file to a CSS file.

For each SVG file a CSS file will be generated, containing the CSS-rules defined inside the SVG file.

Install

Install with npm

npm install extract-svg-styles --save

Usage

var extractSvg = require(‘extract-svg-styles’);
extractSvg.extract(options);

Options

src: Glob string with path to source SVGs
out: Output directories
- svg: Output directory for SVGs (optional)
- style: Output directory for Stylesheets
extension: File name extension for Stylesheets (default is ‘css’, useful for ’scss’)
classPrefix: Prefix for class names to target SVGs
idHandling: none Avoid ID collisions when using multiple SVGs in a page. class will transform the IDs to a class, remove will get rid of the IDs, prefix will keep the IDs but prefix them with the file name.

Example

Usage with an exapmle configuration object:

extractSvg.extract({
    src: './test/src/**/*.svg',
    out: {
        style: './test/dest/css',
        svg: './test/dest/svg'
    },
    classPrefix: 'icon-'
});

Usage with Grunt

This module can also be used in automated tasks using Grunt.

module.exports = function(grunt) {

    grunt.initConfig({
        'extract-svg-styles': {
            options: {
                styleDest: './test/dest/css',
                classPrefix: 'icon-',
            },
            all: {
                src: './test/src/**/*.svg',
                dest: './test/dest/svg'
            }
        }
    });

    grunt.loadNpmTasks('extract-svg-styles');

    grunt.registerTask('default', ['extract-svg-styles']);
}

Options to use extract-svg-styles with Grunt are the same as for the extract function with the exception of src and out.

out.style is styleDest in Grunt, out.svg is the regular Grunt dest property. If dest is omitted, only the stylesheets will be generated.

Usage with Gulp

This module can also be used in automated tasks using Gulp. Make sure to require the stream object of the plugin as in the example below:

var gulp = require('gulp');
var extractSvg = require('./index.js').stream;

gulp.task('extract-svg-styles', function () {
    gulp.src('./test/src/**/*.svg')
    .pipe(extractSvg.extract({
        styleDest: './test/dest/css',
        classPrefix: 'icon-',
        idHandling: 'class'
    }))
    .pipe(gulp.dest('./test/dest/svg'));
});

gulp.task('default', ['extract-svg-styles']);

Options to use with Gulp are the same as for the extract method with the exception of src and out. Use gulp.src and gulp.dest instead, styleDest is used to specify the output directory for the stylesheets.
