You should add in your code before the client code or set code,

(async () => {
   client.connect();
})();

block.

you have to running redis-server on docker.

docker run -d --name redis-stack-server -p 6379:6379 redis/redis-stack-server:latest

const redis = require("redis");
const client = redis.createClient({
    host: '127.0.0.1',
    port: 6379
});

 client.on("error", error => {
   if(error) {
       console.error("ERROR***",error);
   }else {
       console.log("Redis connect.");
   }
});

client.connect();

//SET
await client.set("user_name", "Furkan", (err, msg) => {
   if(err) {
       console.error("Error while connecting redis", err);
   }else {
       console.log(msg);
   } 
})

const message = await client.get('user_name');
console.log(message);

client.disconnect();

I know this works. But I'm a beginner so I don't know why putting await solves the problem.

But you most definitely have to do client.connect() before client.get or client.set. Because you have to make a connection first.
