The Backend process of React Native Messaging App Backend are built using the core components of Node, Express, MongoDB, SocketIO. The theme has also been constantly incorporating various other latest technologies.
Feathers is a minimalist, service-oriented, real-time web framework for modern applications that puts real-time communication at the forefront rather than as an afterthought.Built on top ofExpress, Feathers has embodied the same spirit. It is comprised of a bunch of small modules that are all completely optional and the core weighs in at just a few hundred lines of code.Most real-time* web frameworks only allow clients to be pushed data in real time. You interact with your server over REST and then receive events over websockets or, even worse, the client polls for changes (which isn't really real-time).
The whole Feathers ecosystem has been modeled around supporting real-time communication and making it a first class citizen instead of a hacky add-on. You can even forgo REST altogether and simply use websockets to communicate with your app, making it ideal for real-time IoT devices, among other things.
