websocket.io

library0.2.1jsnpmunverified

websocket.io v0.2.1 is a minimalistic WebSocket server library originally extracted from Socket.IO. It supports multiple WebSocket protocol versions (draft-75 through RFC 6455) and provides a standalone server or attach mode for Node.js HTTP servers. The package is deprecated and unmaintained; it was last published in 2012 and targets Node 0.6. It is superseded by modern WebSocket libraries like ws or uWebSockets.js.

Install & Compatibility

Where this runs

No compatibility data collected yet for this library.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default

✓ const ws = require('websocket.io')

✗ import ws from 'websocket.io'

The package is CommonJS only; ES modules are not supported.

Server

✓ const Server = require('websocket.io').Server

✗ const { Server } = require('websocket.io')

Though destructuring works in many environments, the package's export is a function with attached properties; require() the whole module.

Socket

✓ const Socket = require('websocket.io').Socket

Access via top-level export; no separate import path.

Creates a standalone WebSocket server on port 3000 and handles connection, message, and close events.

const ws = require('websocket.io'); const server = ws.listen(3000); server.on('connection', (client) => { client.on('message', (data) => console.log('Received:', data)); client.on('close', () => console.log('Client disconnected')); client.send('Hello from websocket.io'); }); console.log('WebSocket server listening on port 3000');

Known issues

deprecatedwebsocket.io is deprecated and no longer maintained.

fix

Migrate to modern WebSocket libraries such as 'ws', 'uWebSockets.js', or 'socket.io' (v2+).

affects: >=0.0.1

gotchaTargets Node 0.6 only; may not work on modern Node.js versions.

fix

Use a newer library compatible with your Node.js version (e.g., 'ws' for Node >=6).

affects: >=0.0.1

gotchaThe library does not support ES modules; using import instead of require will fail.

fix

Use CommonJS require() or wrap with dynamic import() if necessary.

affects: >=0.0.1
