Deprecated!
The remove undefined plugin (fela-plugin-remove-undefined) is deprecated, please remove it from your Fela configuration.
Fela automatically removes 'undefined' values making this plugin obsolete.

fela-plugin-remove-undefined

Removes any undefined value or string values containing undefined. It also checks array values. This plugin has been used to ensure auto prefixing to work. It is not necessary anymore as Fela automatically strips all undefined values.

yarn add fela-plugin-remove-undefined

You may alternatively use npm i --save fela-plugin-remove-undefined.
