feathers

Feathers is a web framework for building two things at once: real-time applications and REST APIs. A REST API is a standard way for a website or app to ask a server for data (for example, fetch a list of users); real-time means the server can also push updates to the client the moment something changes, so clients see new data without refreshing. The README describes Feathers as lightweight and says you can write your app in either JavaScript or TypeScript.

According to the README, Feathers is not tied to one database or one frontend. It can interact with any backend technology, supports over a dozen databases, and works with frontend technologies the README explicitly names: React, VueJS, Angular, React Native, Android, and iOS. The getting-started section shows the basic flow: install a small command-line tool, run a generator that scaffolds an app for you, then start the server. The framework provides the plumbing that turns your data resources into both a REST API and a real-time channel at the same time, so the same code serves both kinds of clients.

You would reach for Feathers when you want a Node.js back end that exposes an API and pushes live updates without writing two separate systems for it, for example a chat app, a collaborative dashboard, or any product where users need to see changes as they happen. The README states it runs on Node.js and is published on npm. The full README is longer than what was provided.
