# API

## <tt>svgo([options])</tt>

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);
});

### 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)
});
