## What it is
NowJS is a Node.js library that simplifies building real-time web applications by transparently synchronizing function calls between server and client over Socket.IO. It lets client-side JavaScript invoke server-side functions (and vice versa) as if they were local, including passing callbacks.

## Use cases
- build a real-time chat app in node.js
- call server functions directly from browser javascript
- synchronize state between server and clients in real time
- add live updates to an express web app
- push events from server to browser without writing ajax

## When to choose
- you are maintaining a legacy node.js app already using NowJS
- you want dead-simple RPC-style realtime sync on an old node codebase

## When to avoid
- starting a new project - the library is unmaintained since ~2017
- you need modern websocket features, scaling, or security updates
- you prefer actively maintained alternatives like socket.io or socketstream

## Facets
- artifact type: library
- maturity: abandoned
- function: websocket, rpc, web-framework, middleware
- domain: web-development
- platform: -
- tags: realtime, socket-io, remote-procedure-calls, sync, nodejs-library, real-time, javascript, nodejs, web-server
