Luminus vs FeathersJS

Luminus allows using ClojureScript for client-side development. This allows sharing things like validation logic between the server and the client.

Luminus is built on a stack of composable libraries that can be easily swapped to make the application fit the needs of the user. The applications are generated using Leiningen templates and can be initialized with a specific set of features, such as database connections, needed for a specific application.

Luminus provides step-by-step documentation on how to accomplish common tasks.

Luminus is small and flexible. It's geared towards interactive development using the REPL. You can see your changes as you're working without having to restart the application.

Feather can sync events happening in two different Node processes or even servers in real-time. For example: an event happens in server A, the user connected to server B is instantly notified of that event.

This is done through a central Redis or Mongo collection or through a websocket libraries' clustering library.

Through services, Feathers provides instant CRUD functionality, it also can easily expose a RESTful and real-time API through HTTP/HTTPS and websockets.

Since Feathers itself is built on top of Express (it's a thin wrapper over socket.io, primus and Express) and because of Feathers' highly modular nature, it's very easy to integrate Feathers in an existing Express project.

Feathers makes extensive use of modules (which are called Feathers services). These services work like ExpressJS middleware and can be used with app.use('/path', serviceObject).

Services help developers keep their applications modular and as minimal as possible, without any unnecessary libraries or bloat.

FeatherJS uses primus which is a universal wrapper for real-time frameworks. Through primus you can easily choose which socket transport you want to use.
