How to use the retryStrategy

[Ajido]

I don’t want to block the program, even if an error occurs, but I want to keep on reconnect always.
In this case, does the code below look OK?

'use strict';

let Promise = require('bluebird');

let Redis = require('ioredis');
let redis = new Redis({
  sentinels: [
    { host: '127.0.0.1', port: 15379 },
    { host: '127.0.0.1', port: 15380 },
    { host: '127.0.0.1', port: 15381 }
  ],
  name: 'mymaster',
  enableOfflineQueue: false,
  retryStrategy: function(times) {
    if (times < 3) {
      return 200;
    }
  }
});

Redis.Promise.onPossiblyUnhandledRejection(function(err) {
  console.error(err);
});

let func = Promise.coroutine(function* () {
  let key = 'foo:' + Math.random();

  // DO NOT STOP IF ERROR OCCURS, BUT KEEP ON RECONNECT
  try {
    yield redis.setex(key, 10, 'xxxxxxxxx');
    let value = yield redis.get(key);
    console.log(Date.now(), value);
  }
  catch (err) {
    console.error(err);
  }
});

let loop = function() {
  func().then(loop).catch(function(err) {
    console.error(err.stack);
    process.exit(1);
  });
}

redis.on('end', function() {
  // Reconnect manually after finished all retry
  redis.connect();
});

redis.once('ready', function() {
  loop();
});

Looks good to me. Does it work?

[Ajido]

Yes, it works.
Thanks!

Just a note, the following code also works:

var redis = new Redis(6880);

var func = Redis.Promise.coroutine(function *() {
  try {
    // set timeout
    var bar = yield redis.get('foo').timeout(1000);
  } catch (e) {
    console.log(e);
    // e: [TimeoutError: operation timed out]
  }
  console.log('bar', bar);
});

func();

I didn't know that. Thank you, I will.
