UPL is a library for Pengu Loader that provides a developer most of the common features they would need while developing an advanced Pengu plugin.

To use UPL in your project install it from npm:

npm install pengu-upl

Currently UPL provides the following features:

• Document observer supporting shadowdom.
• Ember components hooking.
• WebSocket hooking.
• XHR hooking.

Currently not implemented but is work in progress:

• Add support of IFrames to observer.
• Add simple API to create and manage settings.
• Fetch hooking.
