var redis = context.global.get('redis');  
client = redis.createClient(6379,'localhost');  
var test=client.hget('hash key','hashtest 1', function(err, results) {  
if (err) {  
} else {  
// do something with results  
console.log(results);  
client.quit();

```
}

```

});  
console.log("Value=="+test);  
msg.payload={"Value":test};

If you share code, please format it properly using ```

Your Redis request returns the data in a callback function, so that part runs asynchronously and gets executed _after_ your log output. You need to send the data **inside** your callback function using `node.send(msg)`. Have a look at the [docs](https://nodered.org/docs/user-guide/writing-functions) under "Sending messages asynchronously".

I would consider using one of the existing Redis nodes found [here](https://flows.nodered.org/?term=redis&num_pages=1). That makes it _a lot_ easier than doing this in a function node.

NOTE: I would recommend this one, I have been using it myself for some time now.
