The CSS minifier we currently use (clean-css) is not maintained and lacks support for new CSS features. CSSNano is a replacement that supports features we need (primarily container queries). This CL only adds the relevant dependencies, and does not use it. I will do that (and remove clean-css) in a follow-up.

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.
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)
});
You can view the full list of plugins here.
