Redis-backed store functionality, like socket.io pre-v1.x

Usage

Create a middleware to add store functions .get(), .set(), .has(), .del() functions to each socket instance.

var io = require("socket.io")();
var SocketStore = require("socket.io-store");
var redis = require("redis");
var redisClient = redis.createClient();

SocketStore.initialize({ redisClient: redisClient });

io.use(SocketStore.middleware());

io.on("connection", function (socket) {

	socket.on("message", function (from, message) {
		var data = JSON.stringify({
			from: from,
			message: message
		});
		socket.set("lastMessage", data, function (err) {
			if (err) {
				socket.emit("error", err);
			}
		});
	});

	socket.on("history", function () {
		socket.get("lastMessage", function (err, data) {
			if (err) {
				socket.emit("error", err);
			}
			else if (data) {
				var message = JSON.parse(data);
				var response = "I last received a message by " + message.from + " saying " + message.message ".";
				socket.emit("history message", response);
				socket.del("lastMessage");
			}
			else {
				socket.emit("history message", "I got nothin'.");
			}
		});
	});
});
