@author Josh Adell <josh.adell@gmail.com>
A port of the box2djs library into a node module.
Here is the box2d "Hello World" program from http://www.box2d.org/ written for node:
--- BEGIN CODE EXAMPLE ---
var sys = require("sys"),
b2d = require("./box2dnode");
// Define world
var worldAABB = new b2d.b2AABB();
worldAABB.lowerBound.Set(-100.0, -100.0);
worldAABB.upperBound.Set(100.0, 100.0);
var gravity = new b2d.b2Vec2(0.0, -10.0);
var doSleep = true;
var world = new b2d.b2World(worldAABB, gravity, doSleep);
// Ground Box
var groundBodyDef = new b2d.b2BodyDef();
groundBodyDef.position.Set(0.0, -10.0);
var groundBody = world.CreateBody(groundBodyDef);
var groundShapeDef = new b2d.b2PolygonDef();
groundShapeDef.SetAsBox(50.0, 10.0);
groundBody.CreateShape(groundShapeDef);
// Dynamic Body
var bodyDef = new b2d.b2BodyDef();
bodyDef.position.Set(0.0, 4.0);
var body = world.CreateBody(bodyDef);
var shapeDef = new b2d.b2PolygonDef();
shapeDef.SetAsBox(1.0, 1.0);
shapeDef.density = 1.0;
shapeDef.friction = 0.3;
body.CreateShape(shapeDef);
body.SetMassFromShapes();
// Run Simulation!
var timeStep = 1.0 / 60.0;
var iterations = 10;
for (var i=0; i < 60; i++) {
world.Step(timeStep, iterations);
var position = body.GetPosition();
var angle = body.GetAngle();
sys.puts(i+": <"+position.x+", "+position.y+"> @"+angle);
}
--- END CODE EXAMPLE ---

# Socket.IO
Socket.IO is a Node.JS project that makes WebSockets and realtime possible in
all browsers. It also enhances WebSockets by providing built-in multiplexing,
horizontal scalability, automatic JSON encoding/decoding, and more.
## How to Install
```bash
npm install socket.io
```
## How to use
First, require `socket.io`:
```js
var io = require('socket.io');
```
Next, attach it to a HTTP/HTTPS server. If you're using the fantastic `express`
web framework:
```js
var app = express.createServer()
, io = io.listen(app);
app.listen(80);
io.sockets.on('connection', function (socket) {
socket.emit('news', { hello: 'world' });
socket.on('my other event', function (data) {
console.log(data);
});
});
```
Finally, load it from the client side code:
```html
<script src="/socket.io/socket.io.js"></script>
<script>
var socket = io.connect('http://localhost');
socket.on('news', function (data) {
console.log(data);
socket.emit('my other event', { my: 'data' });
});
</script>
```
For more thorough examples, look at the `examples/` directory.
## Short recipes
### Sending and receiving events.
Socket.IO allows you to emit and receive custom events.
Besides `connect`, `message` and `disconnect`, you can emit custom events:
```js
// note, io.listen(<port>) will create a http server for you
var io = require('socket.io').listen(80);
io.sockets.on('connection', function (socket) {
io.sockets.emit('this', { will: 'be received by everyone' });
socket.on('private message', function (from, msg) {
console.log('I received a private message by ', from, ' saying ', msg);
});
socket.on('disconnect', function () {
io.sockets.emit('user disconnected');
});
});
```
### Storing data associated to a client
Sometimes it's necessary to store data associated with a client that's
necessary for the duration of the session.
#### Server side
```js
var io = require('socket.io').listen(80);
io.sockets.on('connection', function (socket) {
socket.on('set nickname', function (name) {
socket.set('nickname', name, function () { socket.emit('ready'); });
});
socket.on('msg', function () {
socket.get('nickname', function (err, name) {
console.log('Chat message by ', name);
});
});
});
```
#### Client side
```html
<script>
var socket = io.connect('http://localhost');
socket.on('connect', function () {
socket.emit('set nickname', confirm('What is your nickname?'));
socket.on('ready', function () {
console.log('Connected !');
socket.emit('msg', confirm('What is your message?'));
});
});
</script>
```
### Restricting yourself to a namespace
If you have control over all the messages and events emitted for a particular
application, using the default `/` namespace works.
If you want to leverage 3rd-party code, or produce code to share with others,
socket.io provides a way of namespacing a `socket`.
This has the benefit of `multiplexing` a single connection. Instead of
socket.io using two `WebSocket` connections, it'll use one.
The following example defines a socket that listens on '/chat' and one for
'/news':
#### Server side
```js
var io = require('socket.io').listen(80);
var chat = io
.of('/chat')
.on('connection', function (socket) {
socket.emit('a message', { that: 'only', '/chat': 'will get' });
chat.emit('a message', { everyone: 'in', '/chat': 'will get' });
});
var news = io
.of('/news');
.on('connection', function (socket) {
socket.emit('item', { news: 'item' });
});
```
#### Client side:
```html
<script>
var chat = io.connect('http://localhost/chat')
, news = io.connect('http://localhost/news');
chat.on('connect', function () {
chat.emit('hi!');
});
news.on('news', function () {
news.emit('woot');
});
</script>
```
### Sending volatile messages.
Sometimes certain messages can be dropped. Let's say you have an app that
shows realtime tweets for the keyword `bieber`.
If a certain client is not ready to receive messages (because of network slowness
or other issues, or because he's connected through long polling and is in the
middle of a request-response cycle), if he doesn't receive ALL the tweets related
to bieber your application won't suffer.
In that case, you might want to send those messages as volatile messages.
#### Server side
```js
var io = require('socket.io').listen(80);
io.sockets.on('connection', function (socket) {
var tweets = setInterval(function () {
getBieberTweet(function (tweet) {
socket.volatile.emit('bieber tweet', tweet);
});
}, 100);
socket.on('disconnect', function () {
clearInterval(tweets);
});
});
```
#### Client side
In the client side, messages are received the same way whether they're volatile
or not.
### Getting acknowledgements
Sometimes, you might want to get a callback when the client confirmed the message
reception.
To do this, simply pass a function as the last parameter of `.send` or `.emit`.
What's more, when you use `.emit`, the acknowledgement is done by you, which
means you can also pass data along:
#### Server side
```js
var io = require('socket.io').listen(80);
io.sockets.on('connection', function (socket) {
socket.on('ferret', function (name, fn) {
fn('woot');
});
});
```
#### Client side
```html
<script>
var socket = io.connect(); // TIP: .connect with no args does auto-discovery
socket.on('connect', function () { // TIP: you can avoid listening on `connect` and listen on events directly too!
socket.emit('ferret', 'tobi', function (data) {
console.log(data); // data will be 'woot'
});
});
</script>
```
### Broadcasting messages
To broadcast, simply add a `broadcast` flag to `emit` and `send` method calls.
Broadcasting means sending a message to everyone else except for the socket
that starts it.
#### Server side
```js
var io = require('socket.io').listen(80);
io.sockets.on('connection', function (socket) {
socket.broadcast.emit('user connected');
socket.broadcast.json.send({ a: 'message' });
});
```
### Rooms
Sometimes you want to put certain sockets in the same room, so that it's easy
to broadcast to all of them together.
Think of this as built-in channels for sockets. Sockets `join` and `leave`
rooms in each socket.
#### Server side
```js
var io = require('socket.io').listen(80);
io.sockets.on('connection', function (socket) {
socket.join('justin bieber fans');
socket.broadcast.to('justin bieber fans').emit('new fan');
io.sockets.in('rammstein fans').emit('new non-fan');
});
```
### Using it just as a cross-browser WebSocket
If you just want the WebSocket semantics, you can do that too.
Simply leverage `send` and listen on the `message` event:
#### Server side
```js
var io = require('socket.io').listen(80);
io.sockets.on('connection', function (socket) {
socket.on('message', function () { });
socket.on('disconnect', function () { });
});
```
#### Client side
```html
<script>
var socket = io.connect('http://localhost/');
socket.on('connect', function () {
socket.send('hi');
socket.on('message', function (msg) {
// my msg
});
});
</script>
```
### Changing configuration
Configuration in socket.io is TJ-style:
#### Server side
```js
var io = require('socket.io').listen(80);
io.configure(function () {
io.set('transports', ['websocket', 'flashsocket', 'xhr-polling']);
});
io.configure('development', function () {
io.set('transports', ['websocket', 'xhr-polling']);
io.enable('log');
});
```

## LOL, WUT?
It basically allows you to allow or disallow Flash Player sockets from accessing your site.
## Installation
```bash
npm install policyfile
```
## Usage
The server is based on the regular and know `net` and `http` server patterns. So it you can just listen
for all the events that a `net` based server emits etc. But there is one extra event, the `connect_failed`
event. This event is triggered when we are unable to listen on the supplied port number.
### createServer
Creates a new server instance and accepts 2 optional arguments:
- `options` **Object** Options to configure the server instance
- `log` **Boolean** Enable logging to STDOUT and STDERR (defaults to true)
- `origins` **Array** An Array of origins that are allowed by the server (defaults to *:*)
```js
var pf = require('policyfile');
pf.createServer();
pf.listen();
```
#### server.listen
Start listening on the server and it takes 3 optional arguments
- `port` **Number** On which port number should we listen? (defaults to 843, which is the first port number the FlashPlayer checks)
- `server` **Server** A http server, if we are unable to accept requests or run the server we can also answer the policy requests inline over the supplied HTTP server.
- `callback` **Function** A callback function that is called when listening to the server was successful.
```js
var pf = require('policyfile');
pf.createServer();
pf.listen(1337, function(){
console.log(':3 yay')
});
```
Changing port numbers can be handy if you do not want to run your server as root and have port 843 forward to a non root port number (aka a number above 1024).
```js
var pf = require('policyfile')
, http = require('http');
server = http.createServer(function(q,r){r.writeHead(200);r.end('hello world')});
server.listen(80);
pf.createServer();
pf.listen(1337, server, function(){
console.log(':3 yay')
});
```
Support for serving inline requests over a existing HTTP connection as the FlashPlayer will first check port 843, but if it's unable to get a response there it will send a policy file request over port 80, which is usually your http server.
#### server.add
Adds more origins to the policy file you can add as many arguments as you like.
```js
var pf = require('policyfile');
pf.createServer(['google.com:80']);
pf.listen();
pf.add('blog.3rd-Eden.com:80', 'blog.3rd-Eden.com:8080'); // now has 3 origins
```
#### server.add
Adds more origins to the policy file you can add as many arguments as you like.
```js
var pf = require('policyfile');
pf.createServer(['blog.3rd-Eden.com:80', 'blog.3rd-Eden.com:8080']);
pf.listen();
pf.remove('blog.3rd-Eden.com:8080'); // only contains the :80 version now
```
#### server.close
Shuts down the server
```js
var pf = require('policyfile');
pf.createServer();
pf.listen();
pf.close(); // OH NVM.
```

redis - a node.js redis client
===========================
This is a complete Redis client for node.js. It supports all Redis commands, including many recently added commands like EVAL from
experimental Redis server branches.
Install with:
npm install redis
Pieter Noordhuis has provided a binding to the official `hiredis` C library, which is non-blocking and fast. To use `hiredis`, do:
npm install hiredis redis
If `hiredis` is installed, `node_redis` will use it by default. Otherwise, a pure JavaScript parser will be used.
If you use `hiredis`, be sure to rebuild it whenever you upgrade your version of node. There are mysterious failures that can
happen between node and native code modules after a node upgrade.
## Usage
Simple example, included as `examples/simple.js`:
var redis = require("redis"),
client = redis.createClient();
client.on("error", function (err) {
console.log("Error " + err);
});
client.set("string key", "string val", redis.print);
client.hset("hash key", "hashtest 1", "some value", redis.print);
client.hset(["hash key", "hashtest 2", "some other value"], redis.print);
client.hkeys("hash key", function (err, replies) {
console.log(replies.length + " replies:");
replies.forEach(function (reply, i) {
console.log(" " + i + ": " + reply);
});
client.quit();
});
This will display:
mjr:~/work/node_redis (master)$ node example.js
Reply: OK
Reply: 0

0: hashtest 1
1: hashtest 2
mjr:~/work/node_redis (master)$
## Performance
Here are typical results of `multi_bench.js` which is similar to `redis-benchmark` from the Redis distribution.
It uses 50 concurrent connections with no pipelining.
JavaScript parser:
PING: 20000 ops 42283.30 ops/sec 0/5/1.182
SET: 20000 ops 32948.93 ops/sec 1/7/1.515
GET: 20000 ops 28694.40 ops/sec 0/9/1.740
INCR: 20000 ops 39370.08 ops/sec 0/8/1.269
LPUSH: 20000 ops 36429.87 ops/sec 0/8/1.370
LRANGE (10 elements): 20000 ops 9891.20 ops/sec 1/9/5.048
LRANGE (100 elements): 20000 ops 1384.56 ops/sec 10/91/36.072
hiredis parser:
PING: 20000 ops 46189.38 ops/sec 1/4/1.082
SET: 20000 ops 41237.11 ops/sec 0/6/1.210
GET: 20000 ops 39682.54 ops/sec 1/7/1.257
INCR: 20000 ops 40080.16 ops/sec 0/8/1.242
LPUSH: 20000 ops 41152.26 ops/sec 0/3/1.212
LRANGE (10 elements): 20000 ops 36563.07 ops/sec 1/8/1.363
LRANGE (100 elements): 20000 ops 21834.06 ops/sec 0/9/2.287
The performance of `node_redis` improves dramatically with pipelining, which happens automatically in most normal programs.
### Sending Commands
Each Redis command is exposed as a function on the `client` object.
All functions take either take either an `args` Array plus optional `callback` Function or
a variable number of individual arguments followed by an optional callback.
Here is an example of passing an array of arguments and a callback:
client.mset(["test keys 1", "test val 1", "test keys 2", "test val 2"], function (err, res) {});
Here is that same call in the second style:
client.mset("test keys 1", "test val 1", "test keys 2", "test val 2", function (err, res) {});
Note that in either form the `callback` is optional:
client.set("some key", "some val");
client.set(["some other key", "some val"]);
For a list of Redis commands, see [Redis Command Reference](http://redis.io/commands)
The commands can be specified in uppercase or lowercase for convenience. `client.get()` is the same as `client.GET()`.
Minimal parsing is done on the replies. Commands that return a single line reply return JavaScript Strings,
integer replies return JavaScript Numbers, "bulk" replies return node Buffers, and "multi bulk" replies return a
JavaScript Array of node Buffers. `HGETALL` returns an Object with Buffers keyed by the hash keys.
# API
## Connection Events
`client` will emit some events about the state of the connection to the Redis server.
### "ready"
`client` will emit `ready` a connection is established to the Redis server and the server reports
that it is ready to receive commands. Commands issued before the `ready` event are queued,
then replayed just before this event is emitted.
### "connect"
`client` will emit `connect` at the same time as it emits `ready` unless `client.options.no_ready_check`
is set. If this options is set, `connect` will be emitted when the stream is connected, and then
you are free to try to send commands.
### "error"
`client` will emit `error` when encountering an error connecting to the Redis server.
Note that "error" is a special event type in node. If there are no listeners for an
"error" event, node will exit. This is usually what you want, but it can lead to some
cryptic error messages like this:
mjr:~/work/node_redis (master)$ node example.js
node.js:50
throw e;
^
Error: ECONNREFUSED, Connection refused
at IOWatcher.callback (net:870:22)
at node.js:607:9
Not very useful in diagnosing the problem, but if your program isn't ready to handle this,
it is probably the right thing to just exit.
`client` will also emit `error` if an exception is thrown inside of `node_redis` for whatever reason.
It would be nice to distinguish these two cases.
### "end"
`client` will emit `end` when an established Redis server connection has closed.
### "drain"
`client` will emit `drain` when the TCP connection to the Redis server has been buffering, but is now
writable. This event can be used to stream commands in to Redis and adapt to backpressure. Right now,
you need to check `client.command_queue.length` to decide when to reduce your send rate. Then you can
resume sending when you get `drain`.
### "idle"
`client` will emit `idle` when there are no outstanding commands that are awaiting a response.
## redis.createClient(port, host, options)
Create a new client connection. `port` defaults to `6379` and `host` defaults
to `127.0.0.1`. If you have `redis-server` running on the same computer as node, then the defaults for
port and host are probably fine. `options` in an object with the following possible properties:
* `parser`: which Redis protocol reply parser to use. Defaults to `hiredis` if that module is installed.
This may also be set to `javascript`.
* `return_buffers`: defaults to false. If set to `true`, then bulk data replies will be returned as node Buffer
objects instead of JavaScript Strings.
`createClient()` returns a `RedisClient` object that is named `client` in all of the examples here.
## client.auth(password, callback)
When connecting to Redis servers that require authentication, the `AUTH` command must be sent as the
first command after connecting. This can be tricky to coordinate with reconnections, the ready check,
etc. To make this easier, `client.auth()` stashes `password` and will send it after each connection,
including reconnections. `callback` is invoked only once, after the response to the very first
`AUTH` command sent.
## client.end()
Forcibly close the connection to the Redis server. Note that this does not wait until all replies have been parsed.
If you want to exit cleanly, call `client.quit()` to send the `QUIT` command after you have handled all replies.
This example closes the connection to the Redis server before the replies have been read. You probably don't
want to do this:
var redis = require("redis"),
client = redis.createClient();
client.set("foo_rand000000000000", "some fantastic value");
client.get("foo_rand000000000000", function (err, reply) {
console.log(reply.toString());
});
client.end();
`client.end()` is useful for timeout cases where something is stuck or taking too long and you want
to start over.
## Friendlier hash commands
Most Redis commands take a single String or an Array of Strings as arguments, and replies are sent back as a single String or an Array of Strings. When dealing with hash values, there are a couple of useful exceptions to this.
### client.hgetall(hash)
The reply from an HGETALL command will be converted into a JavaScript Object by `node_redis`. That way you can interact
with the responses using JavaScript syntax.
Example:
client.hmset("hosts", "mjr", "1", "another", "23", "home", "1234");
client.hgetall("hosts", function (err, obj) {
console.dir(obj);
});
Output:
{ mjr: '1', another: '23', home: '1234' }
### client.hmset(hash, obj, [callback])
Multiple values in a hash can be set by supplying an object:
client.HMSET(key2, {
"0123456789": "abcdefghij",
"some manner of key": "a type of value"
});
The properties and values of this Object will be set as keys and values in the Redis hash.
### client.hmset(hash, key1, val1, ... keyn, valn, [callback])
Multiple values may also be set by supplying a list:
client.HMSET(key1, "0123456789", "abcdefghij", "some manner of key", "a type of value");
## Publish / Subscribe
Here is a simple example of the API for publish / subscribe. This program opens two
client connections, subscribes to a channel on one of them, and publishes to that
channel on the other:
var redis = require("redis"),
client1 = redis.createClient(), client2 = redis.createClient(),
msg_count = 0;
client1.on("subscribe", function (channel, count) {
client2.publish("a nice channel", "I am sending a message.");
client2.publish("a nice channel", "I am sending a second message.");
client2.publish("a nice channel", "I am sending my last message.");
});
client1.on("message", function (channel, message) {
console.log("client1 channel " + channel + ": " + message);
msg_count += 1;
if (msg_count === 3) {
client1.unsubscribe();
client1.end();
client2.end();
}
});
client1.incr("did a thing");
client1.subscribe("a nice channel");
When a client issues a `SUBSCRIBE` or `PSUBSCRIBE`, that connection is put into "pub/sub" mode.
At that point, only commands that modify the subscription set are valid. When the subscription
set is empty, the connection is put back into regular mode.
If you need to send regular commands to Redis while in pub/sub mode, just open another connection.
## Pub / Sub Events
If a client has subscriptions active, it may emit these events:
### "message" (channel, message)
Client will emit `message` for every message received that matches an active subscription.
Listeners are passed the channel name as `channel` and the message Buffer as `message`.
### "pmessage" (pattern, channel, message)
Client will emit `pmessage` for every message received that matches an active subscription pattern.
Listeners are passed the original pattern used with `PSUBSCRIBE` as `pattern`, the sending channel
name as `channel`, and the message Buffer as `message`.
### "subscribe" (channel, count)
Client will emit `subscribe` in response to a `SUBSCRIBE` command. Listeners are passed the
channel name as `channel` and the new count of subscriptions for this client as `count`.
### "psubscribe" (pattern, count)
Client will emit `psubscribe` in response to a `PSUBSCRIBE` command. Listeners are passed the
original pattern as `pattern`, and the new count of subscriptions for this client as `count`.
### "unsubscribe" (channel, count)
Client will emit `unsubscribe` in response to a `UNSUBSCRIBE` command. Listeners are passed the
channel name as `channel` and the new count of subscriptions for this client as `count`. When
`count` is 0, this client has left pub/sub mode and no more pub/sub events will be emitted.
### "punsubscribe" (pattern, count)
Client will emit `punsubscribe` in response to a `PUNSUBSCRIBE` command. Listeners are passed the
channel name as `channel` and the new count of subscriptions for this client as `count`. When
`count` is 0, this client has left pub/sub mode and no more pub/sub events will be emitted.
## client.multi([commands])
`MULTI` commands are queued up until an `EXEC` is issued, and then all commands are run atomically by
Redis. The interface in `node_redis` is to return an individual `Multi` object by calling `client.multi()`.
var redis = require("./index"),
client = redis.createClient(), set_size = 20;
client.sadd("bigset", "a member");
client.sadd("bigset", "another member");
while (set_size > 0) {
client.sadd("bigset", "member " + set_size);
set_size -= 1;
}
// multi chain with an individual callback
client.multi()
.scard("bigset")
.smembers("bigset")
.keys("*", function (err, replies) {
client.mget(replies, redis.print);
})
.dbsize()
.exec(function (err, replies) {
console.log("MULTI got " + replies.length + " replies");
replies.forEach(function (reply, index) {
console.log("Reply " + index + ": " + reply.toString());
});
});
`client.multi()` is a constructor that returns a `Multi` object. `Multi` objects share all of the
same command methods as `client` objects do. Commands are queued up inside the `Multi` object
until `Multi.exec()` is invoked.
You can either chain together `MULTI` commands as in the above example, or you can queue individual
commands while still sending regular client command as in this example:
var redis = require("redis"),
client = redis.createClient(), multi;
// start a separate multi command queue
multi = client.multi();
multi.incr("incr thing", redis.print);
multi.incr("incr other thing", redis.print);
// runs immediately
client.mset("incr thing", 100, "incr other thing", 1, redis.print);
// drains multi queue and runs atomically
multi.exec(function (err, replies) {
console.log(replies); // 101, 2
});
// you can re-run the same transaction if you like
multi.exec(function (err, replies) {
console.log(replies); // 102, 3
client.quit();
});
In addition to adding commands to the `MULTI` queue individually, you can also pass an array
of commands and arguments to the constructor:
var redis = require("redis"),
client = redis.createClient(), multi;
client.multi([
["mget", "multifoo", "multibar", redis.print],
["incr", "multifoo"],
["incr", "multibar"]
]).exec(function (err, replies) {
console.log(replies);
});
## Monitor mode
Redis supports the `MONITOR` command, which lets you see all commands received by the Redis server
across all client connections, including from other client libraries and other computers.
After you send the `MONITOR` command, no other commands are valid on that connection. `node_redis`
will emit a `monitor` event for every new monitor message that comes across. The callback for the
`monitor` event takes a timestamp from the Redis server and an array of command arguments.
Here is a simple example:
var client = require("redis").createClient(),
util = require("util");
client.monitor(function (err, res) {
console.log("Entering monitoring mode.");
});
client.on("monitor", function (time, args) {
console.log(time + ": " + util.inspect(args));
});
# Extras
Some other things you might like to know about.
## client.server_info
After the ready probe completes, the results from the INFO command are saved in the `client.server_info`
object.
The `versions` key contains an array of the elements of the version string for easy comparison.
> client.server_info.redis_version
'2.3.0'
> client.server_info.versions
[ 2, 3, 0 ]
## redis.print()
A handy callback function for displaying return values when testing. Example:
var redis = require("redis"),
client = redis.createClient();
client.on("connect", function () {
client.set("foo_rand000000000000", "some fantastic value", redis.print);
client.get("foo_rand000000000000", redis.print);
});
This will print:
Reply: OK
Reply: some fantastic value
Note that this program will not exit cleanly because the client is still connected.
## redis.debug_mode
Boolean to enable debug mode and protocol tracing.
var redis = require("redis"),
client = redis.createClient();
redis.debug_mode = true;
client.on("connect", function () {
client.set("foo_rand000000000000", "some fantastic value");
});
This will display:
mjr:~/work/node_redis (master)$ node ~/example.js
send command: *3
$3
SET
$20
foo_rand000000000000
$20
some fantastic value
on_data: +OK
`send command` is data sent into Redis and `on_data` is data received from Redis.
## client.send_command(command_name, args, callback)
Used internally to send commands to Redis. For convenience, nearly all commands that are published on the Redis
Wiki have been added to the `client` object. However, if I missed any, or if new commands are introduced before
this library is updated, you can use `send_command()` to send arbitrary commands to Redis.
All commands are sent as multi-bulk commands. `args` can either be an Array of arguments, or individual arguments,
or omitted completely.
## client.connected
Boolean tracking the state of the connection to the Redis server.
## client.command_queue.length
The number of commands that have been sent to the Redis server but not yet replied to. You can use this to
enforce some kind of maximum queue depth for commands while connected.
Don't mess with `client.command_queue` though unless you really know what you are doing.
## client.offline_queue.length
The number of commands that have been queued up for a future connection. You can use this to enforce
some kind of maximum queue depth for pre-connection commands.
## client.retry_delay
Current delay in milliseconds before a connection retry will be attempted. This starts at `250`.
## client.retry_backoff
Multiplier for future retry timeouts. This should be larger than 1 to add more time between retries.
Defaults to 1.7. The default initial connection retry is 250, so the second retry will be 425, followed by 723.5, etc.
## TODO
Better tests for monitor mode, auth, disconnect/reconnect, and all combinations thereof.
Stream large set/get values into and out of Redis. Otherwise the entire value must be in node's memory.
Performance can be better for very large values.
I think there are more performance improvements left in there for smaller values, especially for large lists of small values.

Changelog
=========
## v0.6.7 - July 30, 2011
(accidentally skipped v0.6.6)
Fix and test for [GH-123]
Passing an Array as as the last argument should expand as users
expect. The old behavior was to coerce the arguments into Strings,
which did surprising things with Arrays.
## v0.6.5 - July 6, 2011
Contributed changes:
* Support SlowBuffers (Umair Siddique)
* Add Multi to exports (Louis-Philippe Perron)
* Fix for drain event calculation (Vladimir Dronnikov)
Thanks!
## v0.6.4 - June 30, 2011
Fix bug with optional callbacks for hmset.
## v0.6.2 - June 30, 2011
Bugs fixed:
* authentication retry while server is loading db (danmaz74) [GH-101]
* command arguments processing issue with arrays
New features:
* Auto update of new commands from redis.io (Dave Hoover)
* Performance improvements and backpressure controls.
* Commands now return the true/false value from the underlying socket write(s).
* Implement command_queue high water and low water for more better control of queueing.
See `examples/backpressure_drain.js` for more information.
## v0.6.1 - June 29, 2011
Add support and tests for Redis scripting through EXEC command.
Bug fix for monitor mode. (forddg)
Auto update of new commands from redis.io (Dave Hoover)
## v0.6.0 - April 21, 2011
Lots of bugs fixed.
* connection error did not properly trigger reconnection logic [GH-85]
* client.hmget(key, [val1, val2]) was not expanding properly [GH-66]
* client.quit() while in pub/sub mode would throw an error [GH-87]
* client.multi(['hmset', 'key', {foo: 'bar'}]) fails [GH-92]
* unsubscribe before subscribe would make things very confused [GH-88]
* Add BRPOPLPUSH [GH-79]
## v0.5.11 - April 7, 2011
Added DISCARD
I originally didn't think DISCARD would do anything here because of the clever MULTI interface, but somebody
pointed out to me that DISCARD can be used to flush the WATCH set.
## v0.5.10 - April 6, 2011
Added HVALS
## v0.5.9 - March 14, 2011
Fix bug with empty Array arguments - Andy Ray
## v0.5.8 - March 14, 2011
Add `MONITOR` command and special monitor command reply parsing.
## v0.5.7 - February 27, 2011
Add magical auth command.
Authentication is now remembered by the client and will be automatically sent to the server
on every connection, including any reconnections.
## v0.5.6 - February 22, 2011
Fix bug in ready check with `return_buffers` set to `true`.
Thanks to Dean Mao and Austin Chau.
## v0.5.5 - February 16, 2011
Add probe for server readiness.
When a Redis server starts up, it might take a while to load the dataset into memory.
During this time, the server will accept connections, but will return errors for all non-INFO
commands. Now node_redis will send an INFO command whenever it connects to a server.
If the info command indicates that the server is not ready, the client will keep trying until
the server is ready. Once it is ready, the client will emit a "ready" event as well as the
"connect" event. The client will queue up all commands sent before the server is ready, just
like it did before. When the server is ready, all offline/non-ready commands will be replayed.
This should be backward compatible with previous versions.
To disable this ready check behavior, set `options.no_ready_check` when creating the client.
As a side effect of this change, the key/val params from the info command are available as
`client.server_options`. Further, the version string is decomposed into individual elements
in `client.server_options.versions`.
## v0.5.4 - February 11, 2011
Fix excess memory consumption from Queue backing store.
Thanks to Gustaf Sjöberg.
## v0.5.3 - February 5, 2011
Fix multi/exec error reply callback logic.
Thanks to Stella Laurenzo.
## v0.5.2 - January 18, 2011
Fix bug where unhandled error replies confuse the parser.
## v0.5.1 - January 18, 2011
Fix bug where subscribe commands would not handle redis-server startup error properly.
## v0.5.0 - December 29, 2010
Some bug fixes:
* An important bug fix in reconnection logic. Previously, reply callbacks would be invoked twice after
a reconnect.
* Changed error callback argument to be an actual Error object.
New feature:
* Add friendly syntax for HMSET using an object.
## v0.4.1 - December 8, 2010
Remove warning about missing hiredis. You probably do want it though.
## v0.4.0 - December 5, 2010
Support for multiple response parsers and hiredis C library from Pieter Noordhuis.
Return Strings instead of Buffers by default.
Empty nested mb reply bug fix.
## v0.3.9 - November 30, 2010
Fix parser bug on failed EXECs.
## v0.3.8 - November 10, 2010
Fix for null MULTI response when WATCH condition fails.
## v0.3.7 - November 9, 2010
Add "drain" and "idle" events.
## v0.3.6 - November 3, 2010
Add all known Redis commands from Redis master, even ones that are coming in 2.2 and beyond.
Send a friendlier "error" event message on stream errors like connection refused / reset.
## v0.3.5 - October 21, 2010
A few bug fixes.
* Fixed bug with `nil` multi-bulk reply lengths that showed up with `BLPOP` timeouts.
* Only emit `end` once when connection goes away.
* Fixed bug in `test.js` where driver finished before all tests completed.
