Django Channels vs PurpleJS: What are the differences?

Developers describe Django Channels as "It extends Django's abilities beyond HTTP - to handle WebSockets, chat protocols, IoT protocols". It does this by taking the core of Django and adding a fully asynchronous layer underneath, running Django itself in a synchronous mode but handling connections and sockets asynchronously, and giving you the choice to write in either style. On the other hand, PurpleJS is detailed as "An alternative to Node.js for Java projects". PurpleJS is a simple and capable framework for creating performant web applications without leaving Javascript. It is created in Java to give the flexibility and performance Java provides. It's optional to use Java but it's required if you need to embed PurpleJS in existing applications.

Django Channels and PurpleJS can be categorized as "Frameworks (Full Stack)" tools.

Django Channels and PurpleJS are both open source tools. It seems that Django Channels with 3.94K GitHub stars and 542 forks on GitHub has more adoption than PurpleJS with 406 GitHub stars and 19 GitHub forks.
