rwebsocket

Simple auto-reconnect WebSocket adapter

Install

npm i rwebsocket -S

or

yarn add rwebsocket

Usage

const RWebSocket = require('rwebsocket');

const client = new RWebSocket('ws://echo.websocket.org');

client.onopen = function () {
	// as soon as we are connected
	// just send an Hello World! to the server
	client.send('Hello World!');
};

client.onmessage = function (event) {
	// because the server is echo.websocket.org we should receive
	// "Hello World!" right after connection
	console.log('> ', event.data);
};

// connect
client.connect();

If ws://echo.websocket.org is unreachable, RWebSocket will try to reconnect once every 3 seconds (default)

API

The only modifications to the API are:

• the ability to give a 3rd argument to the constructor to set the retryInterval in ms
• the #connect() method to actually create a WebSocket and connect to the server

const client = new RWebSocket('ws://echo.websocket.org', null, 25000);

Reconnection attempts will be made once every 25 seconds
NB: the 'null' param is for the protocol because the constructor is the same as the WebSocket RFC + retryInterval
