library0.1.0jsnpmunverified

A Node.js client for SockJS that only supports the WebSocket transport. Version 0.1.0, released in early development stage. Differentiates from other SockJS clients (e.g., sockjs-client for browsers) by focusing solely on WebSocket transport for Node.js environments, making it lightweight but non-compliant with SockJS protocol fallbacks. Not recommended for production; consider using the full-featured sockjs-client package for browser/Node compatibility.

sockjs-client-ws
✓ var sjsc = require('sockjs-client-ws');
✗ import sjsc from 'sockjs-client-ws';
ESM import not supported; use CommonJS require.
create
✓ var client = sjsc.create(url);
✗ var client = new sjsc(url);
Factory function, not a constructor. Use sjsc.create()
client.write
✓ client.write(data);
✗ client.send(data);
Method is write, not send.

Creates a SockJS WebSocket client, listens for connection, data, and error events, and sends a message.

var sjsc = require('sockjs-client-ws'); var client = sjsc.create("http://localhost:9999/echo"); client.on('connection', function () { console.log('Connected'); client.write("Hello SockJS!"); }); client.on('data', function (msg) { console.log('Received:', msg); }); client.on('error', function (e) { console.error('Error:', e); });
