How to connect to ElastiCache cluster using node.js

Question

We know that ElastiCache is not recommended to be accessed outside Amazon instances, so we're trying below stuff inside Amazon EC2 instances only.

We've got an ElastiCache Redis Cluster with 9 nodes. When we try to connect to it using normal redis implementation, it throws some Moved errors

None of these implementations is working. Any suggestions, please?

This code will work:

var RedisClustr = require('redis-clustr');

var RedisClient = require('redis');

var config = require("./config.json");

var redis = new RedisClustr({

    servers: [

        {

            host: config.redisClusterHost,

            port: config.redisClusterPort

        }

    ],

    createClient: function (port, host) {

        // this is the default behaviour

        return RedisClient.createClient(port, host);

    }

});

//connect to redis

redis.on("connect", function () {

  console.log("connected");

});

//check the functioning

redis.set("framework", "AngularJS", function (err, reply) {

  console.log("redis.set " , reply);

});

redis.get("framework", function (err, reply) {

  console.log("redis.get ", reply);

});
