Catching disconnects and reconnecting listener

[mastef]

Hey there! So sometimes ( not regularly ) the client just stops listening while the node script is still running. On the local mac environment I can trigger this with a wifi disconnect or going into sleep mode. On servers it also seems to happen from time to time, although they should be pretty much online 24/7.

How to catch disconnects and then restart the client?

var client = slack.rtm.client()

client.message(function(message) {
	// do something with message
});

client.listen(
	{token:sl.slacktoken}
);

// how to catch disconnects and reconnect client?

FWIW, botkit had to address this problem too: howdyai/botkit#261 (comment)

I have this in my script… Maybe it (or something similar) should be in the documentation :

// WebSocket reconnection
const listenCb = () => {
  bot.ws.on('close', (code, reason) => {
    console.log(`${new Date()} - WebSocket closed, reconnecting…`)
    bot.listen({token:token}, listenCb)
  })
}

// start listening to the slack team associated to the token
bot.listen({token:token}, listenCb)
