HDEL, HSET not working in NodeJS

can anyone tell me what is wrong in this code?

redis.hdel("hash:" + id + " key" function(err, success) {
    console.log("Hash Deleted");
});

Is there any other way to do it?

And I'm also struggling with HSET:

redis.hset("hash:" + id + " key", "true");

It tells me "wrong number of arguments". What more is it expecting? In the Redis documentation of HSET, there are no more parameters.

So I used HMSET instead, and it works properly. :)

Also, if anyone can tell me, some source where I can find examples of all commands or at least all the hash commands in NodeJS.

Thanks.

HSET takes three parameters, key, field, value. HDEL takes two, key and field. Have you tried, as per the readme:

client.hset("key", "field", "value", callback);

Similarly,

client.hdel("key", "field", callback);
