Package description

What is postcss-svgo?

The postcss-svgo package is a plugin for PostCSS that optimizes SVG vector graphics within CSS. It uses SVGO (SVG Optimizer) under the hood to compress SVG images by removing unnecessary data without affecting the rendering of the SVG. This results in smaller file sizes and potentially faster load times for web pages that use SVG images in their stylesheets.

What are postcss-svgo's main functionalities?

Optimize inline SVG with PostCSS

This code sample demonstrates how to use postcss-svgo to optimize inline SVG within CSS. It sets up PostCSS with the postcss-svgo plugin, specifying a configuration object that includes SVGO plugins like 'removeDoctype' to strip out the doctype declaration from SVGs.

"use strict";\nconst postcss = require('postcss');\nconst postcssSvgo = require('postcss-svgo');\n\npostcss()\n  .use(postcssSvgo({\n    plugins: [{\n      removeDoctype: true\n    }]\n  }))\n  .process('a { background: url('data:image/svg+xml;charset=utf-8,<svg>...</svg>'); }')\n  .then(result => {\n    console.log(result.css);\n  });

API

svgo([options])

options
encode

Type: boolean Default: undefined

If true, it will encode URL-unsafe characters such as <, > and &; false will decode these characters, and undefined will neither encode nor decode the original input. Note that regardless of this setting, # will always be URL-encoded.

plugins

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.

const postcss = require('postcss');
const svgo = require('postcss-svgo');

const opts = {
    plugins: [{
        name: 'preset-default',
        params: {
            overrides: {
                removeViewBox: false,
                removeComments: false,
                cleanupNumericValues: {
                    floatPrecision: 2
                }
            }
        }
    }]
};


postcss([ svgo(opts) ]).process(css).then((result) => {
    console.log(result.css)
});
