fela-plugin-remove-undefined

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.

Installation

npm i --save fela-plugin-remove-undefined

Assuming you are using npm as your package manager you can just npm install.
Otherwise we also provide a UMD. You can easily use it via unpkg. It registers a FelaPluginRemoveUndefined global.
