Suppose we want to delete key="randomkey":

redisClient.del(key, function(err, reply) {
  if (err)
    throw err;

  console.log("deleteRedisKey",reply)
  resolve(reply);
});

Hope this will help you

let redis = require("redis");

var redisclient = redis.createClient({
  host: "localhost",
  port: 6379
});

redisclient.on("connect", function () {
  console.log("Redis Connected");
});

redisclient.on('ready', function () {
  console.log("Redis Ready");
});

redisclient.set("framework", "AngularJS", function (err, reply) {
  console.log("Redis Set" , reply);
});

redisclient.get("framework", function (err, reply) {
  console.log("Redis Get", reply);
});

redisclient.del("framework",function (err, reply) {
  console.log("Redis Del", reply);
});

As everyone above has stated you can use del function. You can assure the successful delete operation using this syntax.

client.del('dummyvalue', function(err, response) {
   if (response == 1) {
      console.log("Deleted Successfully!")
   } else{
    console.log("Cannot delete")
   }
})

Because the DEL command will return (integer) 1 in successful operation.

    redis 127.0.0.1:6379> DEL key 
    Success: (integer) 1
    Unsuccess: (integer) 0

If I remember things correctly, del should do it.
