redis-node/tmp.js

A Complete Redis Client for Node.js

    var sys = require("sys");
    var redis = require("redis-node");
    var client = redis.createClient();    // Create the client
    client.select(2);                     // Select database 2

    // Assign the string "world" to the "hello" key.
    // You can provide a callback to handle the response from Redis
    // that gets asynchronously run upon seeing the response.
    client.set("hello", "world", function (err, status) {
      if (err) throw err;
      console.log(status); // true
    });

    // ... but you don't have to provide a callback.
    client.set("hello", "world");

    // We may or may not be connected yet, but that's ok, since
    // the client queues up any commands.

    // The commands are also idiomatic
    client.hmset("hash", { t: "rex", steg: "asaurus" }, function (err, status) {
      if (err) throw err;
      sys.log(status); // true
    });

    // Support for transactions
    console.log("Transfer from checking to savings.");
    client.transaction( function () {
      client.decrby("checking", 100, function (err, balance) {
        if (err) throw err;
        console.log("Checking Balance: " + balance);
      });
      client.incrby("savings", 100, function (err, balance) {
        if (err) throw err;
        console.log("Savings Balance: " + balance);
      });
    });

    // With automatic transaction discard if there are any syntactic errors
    client.transaction( function () {
      client.set("I'm missing a 2nd argument"); // Our client with automatically discard the transaction
    });
