Optimise inline SVG with PostCSS.
With npm do:
npm install postcss-svgo --save
h1 {
background: url('data:image/svg+xml;charset=utf-8,<?xml version="1.0" encoding="utf-8"?><!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"><svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" xml:space="preserve"><circle cx="50" cy="50" r="40" fill="yellow" /></svg>');
}

svgo([options])
Note that postcss-svgo is an asynchronous processor. It cannot be used like this:
var result = postcss([ svgo() ]).process(css).css;
console.log(result);
Instead make sure your PostCSS runner uses the asynchronous API:
postcss([ svgo() ]).process(css).then(function (result) {
console.log(result.css);
});
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.
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.
var postcss = require('postcss');
var svgo = require('postcss-svgo');
var opts = {
plugins: [{
removeDoctype: false
}, {
removeComments: false
}, {
cleanupNumericValues: {
floatPrecision: 2
}
}, {
convertColors: {
names2hex: false,
rgb2hex: false
}
}]
};
postcss([ svgo(opts) ]).process(css).then(function (result) {
console.log(result.css)
});
