Handle error when redis shuts down

Hello, I have this little node server that communicates with a redis server, I just need some advice how I can make it so the nodejs app doesn’t crash when the redis server goes down. I need it to not crash and try and reconnect to redis, but I am not very experienced with using sockets so I am having quite the trouble, if somebody can help me I would be very greatful!

var express = require('express');
var app = express();
var server = require('http').createServer(app);
var socket = require('socket.io');
var redis = require("redis");
var redisAdapter = require('socket.io-redis');

server.listen(config.nodejs.port, function () {
    console.log('listening on ' + config.nodejs.port);
})

var io = socket.listen(server);
io.set("transports", ["xhr-polling", "websocket", "polling", "htmlfile"]);
io.adapter(redisAdapter({host: config.redis.address, port: config.redis.port}));
io.on('connection', function (client) {
    console.log('Client connected...');
    var sessionId = client.handshake.query.searchSessionId;
    client.join(sessionId);
    console.log('room ' + sessionId)
});


var searchResultQueue = redis.createClient({host: config.redis.address});
var blpopQueue = function () {
    searchResultQueue.blpop('socketio-search-result', 5, function (err, data) {
            blpopQueue();
            if (data) {
                var timestamp = data[1].substring(60, 73);
                var eventId = data[1].substring(14, 46);
                if (Date.now() - timestamp < searchResultTtl) {
                    console.log(eventId + ' ' + timestamp)
                    io.sockets.in(eventId).emit('flights/' + eventId, data[1]);
                } else {
                    console.log(eventId + ' skipped duo expired ttl')
                }
            }
        }
    )
}

blpopQueue();

I resolved this issue using this line: io.of(‘/’).adapter.on(‘error’, function(error){ console.log('error: ', error); });

This still happens for me. I use ioredis as client. I’m listenning on error even of course. It logs the error and then crashes the server.
