Accessing redis channels available on the redis server through 'redis' package in node js

Question

var redis = require('redis');
var redisClient = redis.createClient({host : 'localhost', port : 6379});
var x = redisClient.pubsub.channels //Cuz this is similar to PUBSUB CHANNELS
console.log(x);

The above code returns 'undefined' even when there are channels on my redis server. I'm I using it correctly? If so, is there any other way to access channels available on the redis server.

I'm using the 'redis' package.

You need to use send_command as the PUBSUB command isn't directly supported by the driver:

redisClient.send_command('PUBSUB', [ 'CHANNELS' ], function(err, channels) {
  if (err) {
    console.log('Received an error:', err);
  } else {
    console.log('Channels:', channels);
  }
});
