## 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.

```js
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)
});
```

You can view the [full list of plugins here][plugins].


## Security

This package optimises SVG data URIs; it is not an SVG sanitizer. Do not rely
on it to remove active or unsafe SVG content.

Sanitize user-controlled SVG with a purpose-built sanitizer before
optimisation.


## Usage

See the [PostCSS documentation](https://github.com/postcss/postcss#usage) for
examples for your environment.
