My test code is : 

const redis = require("redis");
const client = redis.createClient(
  PORT,SERVER
);
client.on("error", function (err) {
  console.log("Error " + err);
});

client.smembers("test",function(err,reply) {
  if(err){
    console.error(err);
    return;
  }
  console.log(reply);
  if (!reply.length) {
    redis.sadd("test", "1");
  }
});

client.quit()

It output "[]",but expectedly,it will output "1". Am i wrong?
