What results can you expect?

Some scenarios are shown below:

const redis = require("redis");
var client = redis.createClient('16', '192.168.1.52');

const hash_key = "hash key"
client0.set("string key", "string val", redis.print);

client0.hset(hash_key, "hashtest 1", "some value", redis.print);
client0.hset(["hash key", "hashtest 2", "some other value"], redis.print);

client0.get("string key", redis.print);
client0.get(new Buffer("hash key"), redis.print);

client0.rpush(['frameworks', 'angularjs', 'backbone'], function(err, reply) {
    console.log(reply); //prints 2
});

client0.lrange('frameworks', 0, -1, function(err, reply) {
    console.log(reply); // ['angularjs', 'backbone']
});

In this example, a ‘NodeJS Redis Connection’ and three ‘NodeJS Redis Collection’ objects are created. This extension creates three useSelect links, two useUpdate links and a useInsert link from code redis.js to the three collections corresponding.
