Plugins
All optimizations performed by SVGO are through the various plugins that are either built-in, or provided in your SVGO config.
Built-in plugins are focused around either optimizations or compatibility. However, the plugin architecture is very flexible, so plugins can be made to do effectively anything.
Presets
Presets are generalized SVGO plugin pipelines, though there is only one built-in to SVGO called Preset Default.
The Preset Default pipeline can be used by either:
- Not defining a
pluginsproperty in the config. - Omitting the config altogether.
- Specifying the
preset-defaultplugin.
