svgo example in the readme is no longer valid

[return42]

The svgo example in the readme ...

options: {
  svgo: ['--enable', 'cleanupIDs', '--disable', 'convertColors']
}

... is no longer valid. To configure svgo a config file is needed.

By example, for others who struggle with. Here is what I have done to optimize my SVG for the WEB usage:

Set --config option in the grunt-image options ...

options: {
    svgo: ['--config', 'svg4web.svgo.js']
},

.. and create a config file : svg4web.svgo.js

module.exports = {
  plugins: [
    {
      name: 'preset-default',
    },
    // make diff friendly
    'sortAttrs',
    // Optimize SVG for WEB usage
    'convertStyleToAttrs',
    'removeXMLNS'
 ],
};
