node.js store objects in redis
Since the socket is of type Object
, you need to convert the object to a string before storing and when retrieving the socket, need to convert it back to an object.
You can use
JSON.stringify(socket)
to convert to a string and
JSON.parse(socketstr)
to convert back to an object.
Edit:
Since the release of version 2.0.0
, we are able to store objects as hashes into Redis.
client.hmset("hosts", "mjr", "1", "another", "23", "home", "1234");
client.hgetall("hosts", function (err, obj) {
console.dir(obj);
});

Downvoters: the context here is SET command and ability to store arbitrary objects.
No, you can't do that. You should accept the fact that Redis stores everything as a string (the protocol is text-based, after all). Redis may perform some optimizations and convert some values to integers, but that's its business, not yours.
If you want to store arbitrary objects in Redis, make sure that you serialize them before saving and de-serialize after retrieving.
I'm not sure if you can do that with socket objects, though. They simply describe a system resource (an open connection), after all (TCP sockets, for example). If you manage to serialize the description and deserialize it on another machine, that other machine won't have the connection.
