node-net-reconnect

Reconnection Handler for TCP Socket Connections in node.js

This module will help you reconnect a TCP socket connection if the connection is lost.

When you want to stay connected with a TCP server you need to implement a reconnect logic. This module will keep your connection online if possible. For example, if you want to connect to a service that's not online yet, or when someone pulls the plug.

Example

    let socket = net require('net').Socket()
    let options = { 
      'host' : 'somehost', 
      'port' : someport,
      'retryTime' : 1000, // 1s for every retry
      'retryAlways' : true // retry even if the connection was closed on purpose
    }
    let Reconnect = require('node-net-reconnect')
    let recon = new Reconnect(socket, options)

    socket.connect(options)

    socket.on('connect', function () {

      /* if you enabled retryAlways, a call to 
         socket.end() will reconnect the client.
         In that case you need to close the connection
         through the recon.end() method. */
      setTimeout(function () {
        recon.end()
      }, 10000)

    })
