how to catch `connect` error

https://github.com/luin/ioredis/blob/master/lib/redis/event_handler.js#L76

the default error handler is just noop

connect always throws when the connection is failed regardless of the value of enableOfflineQueue:

var redis = new Redis({
  host: 'non-exists host',
  lazyConnect: true,
  enableOfflineQueue: false
});
redis.connect().catch(function () {
  console.log('should throw');
});

Oh my sweet Jesus! I finally got this working…it would not work with all those fancy attributes inside of new Redis(). Kept it simple and it’s finally doing what daddy wants!

console.time('Redis')
var Redis = require('ioredis'),
  redis = new Redis()
redis.on('error', err => {
  console.log('REDIS: FAILED')
  process.exit(0)
})
redis.on('connect', () => {
  app.set('redis', redis)
  // continue program logic  
  console.timeEnd('Redis')
})
