# Engine.IO: the realtime engine
|
||||
|
||||
[](http://travis-ci.org/socketio/engine.io)
|
||||
[](http://badge.fury.io/js/engine.io)
|
||||
|
||||
`Engine.IO` is the implementation of transport-based
|
||||
cross-browser/cross-device bi-directional communication layer for
|
||||
[Socket.IO](http://github.com/socketio/socket.io).
|
||||
|
||||
## How to use
|
||||
|
||||
### Server
|
||||
|
||||
#### (A) Listening on a port
|
||||
|
||||
```js
|
||||
var engine = require('engine.io');
|
||||
var server = engine.listen(80);
|
||||
|
||||
server.on('connection', function(socket){
|
||||
socket.send('utf 8 string');
|
||||
socket.send(new Buffer([0, 1, 2, 3, 4, 5])); // binary data
|
||||
});
|
||||
```
|
||||
|
||||
#### (B) Intercepting requests for a http.Server
|
||||
|
||||
```js
|
||||
var engine = require('engine.io');
|
||||
var http = require('http').createServer().listen(3000);
|
||||
var server = engine.attach(http);
|
||||
|
||||
server.on('connection', function (socket) {
|
||||
socket.on('message', function(data){ });
|
||||
socket.on('close', function(){ });
|
||||
});
|
||||
```
|
||||
|
||||
#### (C) Passing in requests
|
||||
|
||||
```js
|
||||
var engine = require('engine.io');
|
||||
var server = new engine.Server();
|
||||
|
||||
server.on('connection', function(socket){
|
||||
socket.send('hi');
|
||||
});
|
||||
|
||||
// …
|
||||
httpServer.on('upgrade', function(req, socket, head){
|
||||
server.handleUpgrade(req, socket, head);
|
||||
});
|
||||
httpServer.on('request', function(req, res){
|
||||
server.handleRequest(req, res);
|
||||
});
|
||||
```
|
||||
|
||||
### Client
|
||||
|
||||
```html
|
||||
<script src="/path/to/engine.io.js"></script>
|
||||
<script>
|
||||
var socket = new eio.Socket('ws://localhost/');
|
||||
socket.on('open', function(){
|
||||
socket.on('message', function(data){});
|
||||
socket.on('close', function(){});
|
||||
});
|
||||
</script>
|
||||
```
|
||||
|
||||
For more information on the client refer to the
|
||||
[engine-client](http://github.com/learnboost/engine.io-client) repository.
|
||||
|
||||
## What features does it have?
|
||||
|
||||
- **Maximum reliability**. Connections are established even in the presence of:
|
||||
- proxies and load balancers.
|
||||
- personal firewall and antivirus software.
|
||||
- for more information refer to **Goals** and **Architecture** sections
|
||||
- **Minimal client size** aided by:
|
||||
- lazy loading of flash transports.
|
||||
- lack of redundant transports.
|
||||
- **Scalable**
|
||||
- load balancer friendly
|
||||
- **Future proof**
|
||||
- **100% Node.JS core style**
|
||||
- No API sugar (left for higher level projects)
|
||||
- Written in readable vanilla JavaScript
|
||||
|
||||
## API
|
||||
|
||||
### Server
|
||||
|
||||
<hr><br>
|
||||
|
||||
#### Top-level
|
||||
|
||||
These are exposed by `require('engine.io')`:
|
||||
|
||||
##### Events
|
||||
|
||||
- `flush`
|
||||
- Called when a socket buffer is being flushed.
|
||||
- **Arguments**
|
||||
- `Socket`: socket being flushed
|
||||
- `Array`: write buffer
|
||||
- `drain`
|
||||
- Called when a socket buffer is drained
|
||||
- **Arguments**
|
||||
- `Socket`: socket being flushed
|
||||
|
||||
##### Properties
|
||||
|
||||
- `protocol` _(Number)_: protocol revision number
|
||||
- `Server`: Server class constructor
|
||||
- `Socket`: Socket class constructor
|
||||
- `Transport` _(Function)_: transport constructor
|
||||
- `transports` _(Object)_: map of available transports
|
||||
|
||||
##### Methods
|
||||
|
||||
- `()`
|
||||
- Returns a new `Server` instance. If the first argument is an `http.Server` then the
|
||||
new `Server` instance will be attached to it. Otherwise, the arguments are passed
|
||||
directly to the `Server` constructor.
|
||||
- **Parameters**
|
||||
- `http.Server`: optional, server to attach to.
|
||||
- `Object`: optional, options object (see `Server#constructor` api docs below)
|
||||
|
||||
The following are identical ways to instantiate a server and then attach it.
|
||||
|
||||
```js
|
||||
var httpServer; // previously created with `http.createServer();` from node.js api.
|
||||
|
||||
// create a server first, and then attach
|
||||
var eioServer = require('engine.io').Server();
|
||||
eioServer.attach(httpServer);
|
||||
|
||||
// or call the module as a function to get `Server`
|
||||
var eioServer = require('engine.io')();
|
||||
eioServer.attach(httpServer);
|
||||
|
||||
// immediately attach
|
||||
var eioServer = require('engine.io')(httpServer);
|
||||
|
||||
// with custom options
|
||||
var eioServer = require('engine.io')(httpServer, {
|
||||
maxHttpBufferSize: 1e3
|
||||
});
|
||||
```
|
||||
|
||||
- `listen`
|
||||
- Creates an `http.Server` which listens on the given port and attaches WS
|
||||
to it. It returns `501 Not Implemented` for regular http requests.
|
||||
- **Parameters**
|
||||
- `Number`: port to listen on.
|
||||
- `Object`: optional, options object
|
||||
- `Function`: callback for `listen`.
|
||||
- **Options**
|
||||
- All options from `Server.attach` method, documented below.
|
||||
- **Additionally** See Server `constructor` below for options you can pass for creating the new Server
|
||||
- **Returns** `Server`
|
||||
|
||||
```js
|
||||
var engine = require('engine.io');
|
||||
var server = engine.listen(3000, {
|
||||
pingTimeout: 2000,
|
||||
pingInterval: 10000
|
||||
});
|
||||
|
||||
server.on('connection', /* ... */);
|
||||
```
|
||||
|
||||
- `attach`
|
||||
- Captures `upgrade` requests for a `http.Server`. In other words, makes
|
||||
a regular http.Server WebSocket-compatible.
|
||||
- **Parameters**
|
||||
- `http.Server`: server to attach to.
|
||||
- `Object`: optional, options object
|
||||
- **Options**
|
||||
- All options from `Server.attach` method, documented below.
|
||||
- **Additionally** See Server `constructor` below for options you can pass for creating the new Server
|
||||
- **Returns** `Server` a new Server instance.
|
||||
|
||||
```js
|
||||
var engine = require('engine.io');
|
||||
var httpServer = require('http').createServer().listen(3000);
|
||||
var server = engine.attach(httpServer, {
|
||||
wsEngine: 'uws' // requires having uws as dependency
|
||||
});
|
||||
|
||||
server.on('connection', /* ... */);
|
||||
```
|
||||
|
||||
#### Server
|
||||
|
||||
The main server/manager. _Inherits from EventEmitter_.

|
||||
- **Arguments**
|
||||
- `Socket`: a Socket object
|
||||
|
||||
##### Properties
|
||||
|
||||
**Important**: if you plan to use Engine.IO in a scalable way, please
|
||||
keep in mind the properties below will only reflect the clients connected
|
||||
to a single process.
|
||||
|
||||
- `clients` _(Object)_: hash of connected clients by id.
|
||||
- `clientsCount` _(Number)_: number of connected clients.
|
||||
|
||||
##### Methods
|
||||
|
||||

|
||||
- Initializes the server
|
||||
- **Parameters**
|
||||
- `Object`: optional, options object
|
||||
- **Options**
|
||||
- `pingTimeout` (`Number`): how many ms without a pong packet to
|
||||
consider the connection closed (`5000`)
|
||||
- `pingInterval` (`Number`): how many ms before sending a new ping
|
||||
packet (`25000`)

||||
- `upgradeTimeout` (`Number`): how many ms before an uncompleted transport upgrade is cancelled (`10000`)
|
||||
- `maxHttpBufferSize` (`Number`): how many bytes or characters a message
|
||||
can be, before closing the session (to avoid DoS). Default
|
||||
value is `10E7`.
|
||||
- `allowRequest` (`Function`): A function that receives a given handshake
|
||||
or upgrade request as its first parameter, and can decide whether to
|
||||
continue or not. The second argument is a function that needs to be
|
||||
called with the decided information: `fn(err, success)`, where
|
||||
`success` is a boolean value where false means that the request is
|
||||
rejected, and err is an error code.
|
||||
- `transports` (`<Array> String`): transports to allow connections
|
||||
to (`['polling', 'websocket']`)
|
||||
- `allowUpgrades` (`Boolean`): whether to allow transport upgrades
|
||||
(`true`)
|
||||
- `perMessageDeflate` (`Object|Boolean`): parameters of the WebSocket permessage-deflate extension
|
||||
(see [ws module](https://github.com/einaros/ws) api docs). Set to `false` to disable. (`true`)
|
||||
- `threshold` (`Number`): data is compressed only if the byte size is above this value (`1024`)
|
||||
- `httpCompression` (`Object|Boolean`): parameters of the http compression for the polling transports
|
||||
(see [zlib](http://nodejs.org/api/zlib.html#zlib_options) api docs). Set to `false` to disable. (`true`)

|
||||
- `cookie` (`String|Boolean`): name of the HTTP cookie that
|
||||
contains the client sid to send as part of handshake response
|
||||
headers. Set to `false` to not send one. (`io`)
|
||||
- `cookiePath` (`String|Boolean`): path of the above `cookie`
|
||||
option. If false, no path will be sent, which means browsers will only send the cookie on the engine.io attached path (`/engine.io`).
|
||||
Set false to not save io cookie on all requests. (`/`)
|
||||
- `cookieHttpOnly` (`Boolean`): If `true` HttpOnly io cookie cannot be accessed by client-side APIs, such as JavaScript. (`true`) _This option has no effect if `cookie` or `cookiePath` is set to `false`._
|
||||
- `wsEngine` (`String`): what WebSocket server implementation to use. Specified module must conform to the `ws` interface (see [ws module api docs](https://github.com/websockets/ws/blob/master/doc/ws.md)). Default value is `ws`. An alternative c++ addon is also available by installing `uws` module.

|
||||
- Closes all clients
|
||||

### Client
|
||||
|
||||
<hr><br>
|
||||
|
||||
Exposed in the `eio` global namespace (in the browser), or by
|
||||
`require('engine.io-client')` (in Node.JS).
|
||||
|
||||
For the client API refer to the
|
||||
[engine-client](http://github.com/learnboost/engine.io-client) repository.
|
||||
|
||||
## Debug / logging
|
||||
|
||||
Engine.IO is powered by [debug](http://github.com/visionmedia/debug).
|
||||
In order to see all the debug output, run your app with the environment variable
|
||||
`DEBUG` including the desired scope.
|
||||
|
||||
To see the output from all of Engine.IO's debugging scopes you can use:
|
||||
|
||||
```
|
||||
DEBUG=engine* node myapp
|
||||
```
|
||||
|
||||
## Transports
|
||||
|
||||
- `polling`: XHR / JSONP polling transport.
|
||||
- `websocket`: WebSocket transport.
|
||||
|
||||
## Plugins
|
||||
|
||||
- [engine.io-conflation](https://github.com/EugenDueck/engine.io-conflation): Makes **conflation and aggregation** of messages straightforward.
|
||||
|
||||
## Support
|
||||
|
||||
The support channels for `engine.io` are the same as `socket.io`:
|
||||
- irc.freenode.net **#socket.io**
|
||||
- [Google Groups](http://groups.google.com/group/socket_io)
|
||||
- [Website](http://socket.io)
|
||||
|
||||
## Development
|
||||
|
||||
To contribute patches, run tests or benchmarks, make sure to clone the
|
||||
repository:
|
||||
|
||||
```
|
||||
git clone git://github.com/LearnBoost/engine.io.git
|
||||
```
|
||||
|
||||
Then:
|
||||
|
||||
```
|
||||
cd engine.io
|
||||
npm install
|
||||
```
|
||||
|
||||
## Tests
|
||||
|
||||
Tests run with `npm test`. It runs the server tests that are aided by
|
||||
the usage of `engine.io-client`.
|
||||
|
||||
Make sure `npm install` is run first.
|
||||
|
||||
## Goals
|
||||
|
||||
The main goal of `Engine` is ensuring the most reliable realtime communication.
|
||||
Unlike the previous Socket.IO core, it always establishes a long-polling
|
||||
connection first, then tries to upgrade to better transports that are "tested" on
|
||||
the side.
|
||||
|
||||
During the lifetime of the Socket.IO projects, we've found countless drawbacks
|
||||
to relying on `HTML5 WebSocket` or `Flash Socket` as the first connection
|
||||
mechanisms.
|
||||
|
||||
Both are clearly the _right way_ of establishing a bidirectional communication,
|
||||
with HTML5 WebSocket being the way of the future. However, to answer most business
|
||||
needs, alternative traditional HTTP 1.1 mechanisms are just as good as delivering
|
||||
the same solution.
|
||||
|
||||
WebSocket based connections have two fundamental benefits:
|
||||
|
||||
1. **Better server performance**
|
||||
- _A: Load balancers_<br>
|
||||
Load balancing a long polling connection poses a serious architectural nightmare
|
||||
since requests can come from any number of open sockets by the user agent, but
|
||||
they all need to be routed to the process and computer that owns the `Engine`
|
||||
connection. This negatively impacts RAM and CPU usage.
|
||||
- _B: Network traffic_<br>
|
||||
WebSocket is designed around the premise that each message frame has to be
|
||||
surrounded by the least amount of data. In HTTP 1.1 transports, each message
|
||||
frame is surrounded by HTTP headers and chunked encoding frames. If you try to
|
||||
send the message _"Hello world"_ with xhr-polling, the message ultimately
|
||||
becomes larger than if you were to send it with WebSocket.
|
||||
- _C: Lightweight parser_<br>
|
||||
As an effect of **B**, the server has to do a lot more work to parse the network
|
||||
data and figure out the message when traditional HTTP requests are used
|
||||
(as in long polling). This means that another advantage of WebSocket is
|
||||
less server CPU usage.
|
||||
|
||||
2. **Better user experience**
|
||||
|
||||
Due to the reasons stated in point **1**, the most important effect of being able
|
||||
to establish a WebSocket connection is raw data transfer speed, which translates
|
||||
in _some_ cases in better user experience.
|
||||
|
||||
Applications with heavy realtime interaction (such as games) will benefit greatly,
|
||||
whereas applications like realtime chat (Gmail/Facebook), newsfeeds (Facebook) or
|
||||
timelines (Twitter) will have negligible user experience improvements.
|
||||
|
||||
Having said this, attempting to establish a WebSocket connection directly so far has
|
||||
proven problematic:
|
||||
|
||||
1. **Proxies**<br>
|
||||
Many corporate proxies block WebSocket traffic.
|
||||
|
||||
2. **Personal firewall and antivirus software**<br>
|
||||
As a result of our research, we've found that at least 3 personal security
|
||||
applications block WebSocket traffic.
|
||||
|
||||
3. **Cloud application platforms**<br>
|
||||
Platforms like Heroku or No.de have had trouble keeping up with the fast-paced
|
||||
nature of the evolution of the WebSocket protocol. Applications therefore end up
|
||||
inevitably using long polling, but the seamless installation experience of
|
||||
Socket.IO we strive for (_"require() it and it just works"_) disappears.
|
||||
|
||||
Some of these problems have solutions. In the case of proxies and personal programs,
|
||||
however, the solutions many times involve upgrading software. Experience has shown
|
||||
that relying on client software upgrades to deliver a business solution is
|
||||
fruitless: the very existence of this project has to do with a fragmented panorama
|
||||
of user agent distribution, with clients connecting with latest versions of the most
|
||||
modern user agents (Chrome, Firefox and Safari), but others with versions as low as
|
||||
IE 5.5.
|
||||
|
||||
From the user perspective, an unsuccessful WebSocket connection can translate in
|
||||
up to at least 10 seconds of waiting for the realtime application to begin
|
||||
exchanging data. This **perceptively** hurts user experience.
|
||||
|
||||
To summarize, **Engine** focuses on reliability and user experience first, marginal
|
||||
potential UX improvements and increased server performance second. `Engine` is the
|
||||
result of all the lessons learned with WebSocket in the wild.
|
||||
|
||||
## Architecture
|
||||
|
||||
The main premise of `Engine`, and the core of its existence, is the ability to
|
||||
swap transports on the fly. A connection starts as xhr-polling, but it can
|
||||
switch to WebSocket.
|
||||
|
||||
The central problem this poses is: how do we switch transports without losing
|
||||
messages?
|
||||
|
||||
`Engine` only switches from polling to another transport in between polling
|
||||
cycles. Since the server closes the connection after a certain timeout when
|
||||
there's no activity, and the polling transport implementation buffers messages
|
||||
in between connections, this ensures no message loss and optimal performance.
|
||||
|
||||
Another benefit of this design is that we workaround almost all the limitations
|
||||
of **Flash Socket**, such as slow connection times, increased file size (we can
|
||||
safely lazy load it without hurting user experience), etc.
|
||||
|
||||
## FAQ
|
||||
|
||||
### Can I use engine without Socket.IO ?
|
||||
|
||||
Absolutely. Although the recommended framework for building realtime applications
|
||||
is Socket.IO, since it provides fundamental features for real-world applications
|
||||
such as multiplexing, reconnection support, etc.
|
||||
|
||||
`Engine` is to Socket.IO what Connect is to Express. An essential piece for building
|
||||
realtime frameworks, but something you _probably_ won't be using for building
|
||||
actual applications.
|
||||
|
||||
### Does the server serve the client?
|
||||
|
||||
No. The main reason is that `Engine` is meant to be bundled with frameworks.
|
||||
Socket.IO includes `Engine`, therefore serving two clients is not necessary. If
|
||||
you use Socket.IO, including
|
||||
|
||||
```html
|
||||
<script src="/socket.io/socket.io.js">
|
||||
```
|
||||
|
||||
has you covered.
|
||||
|
||||
### Can I implement `Engine` in other languages?
|
||||
|
||||
Absolutely. The [engine.io-protocol](https://github.com/LearnBoost/engine.io-protocol)
|
||||
repository contains the most up to date description of the specification
|
||||
at all times, and the parser implementation in JavaScript.

|
||||
|
||||
A tiny JavaScript debugging utility modelled after Node.js core's debugging
|
||||
technique. Works in Node.js and web browsers.
|
||||
|
||||
## Installation
|
||||
|
||||
```bash
|
||||
$ npm install debug
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
|
||||
|
||||
Example [_app.js_](./examples/node/app.js):
|
||||
|
||||
```js
|
||||
var debug = require('debug')('http')
|
||||
, http = require('http')
|
||||
, name = 'My App';
|
||||
|
||||
// fake app
|
||||
|
||||
debug('booting %o', name);
|
||||
|
||||
http.createServer(function(req, res){
|
||||
debug(req.method + ' ' + req.url);
|
||||
res.end('hello\n');
|
||||
}).listen(3000, function(){
|
||||
debug('listening');
|
||||
});
|
||||
|
||||
// fake worker of some kind
|
||||
|
||||
require('./worker');
|
||||
```
|
||||
|
||||
Example [_worker.js_](./examples/node/worker.js):
|
||||
|
||||
```js
|
||||
var a = require('debug')('worker:a')
|
||||
, b = require('debug')('worker:b');
|
||||
|
||||
function work() {
|
||||
a('doing lots of uninteresting work');
|
||||
setTimeout(work, Math.random() * 1000);
|
||||
}
|
||||
|
||||
work();
|
||||
|
||||
function workb() {
|
||||
b('doing some work');
|
||||
setTimeout(workb, Math.random() * 2000);
|
||||
}
|
||||
|
||||
workb();
|
||||
```
|
||||
|
||||
The `DEBUG` environment variable is then used to enable these based on space or
|
||||
comma-delimited names.
|
||||
|
||||
Here are some examples:
|
||||
|
||||
<img width="647" alt="screen shot 2017-08-08 at 12 53 04 pm" src="https://user-images.githubusercontent.com/71256/29091703-a6302cdc-7c38-11e7-8304-7c0b3bc600cd.png">
|
||||
<img width="647" alt="screen shot 2017-08-08 at 12 53 38 pm" src="https://user-images.githubusercontent.com/71256/29091700-a62a6888-7c38-11e7-800b-db911291ca2b.png">
|
||||
<img width="647" alt="screen shot 2017-08-08 at 12 53 25 pm" src="https://user-images.githubusercontent.com/71256/29091701-a62ea114-7c38-11e7-826a-2692bedca740.png">
|
||||
|
||||
#### Windows note
|
||||
|
||||
On Windows the environment variable is set using the `set` command.
|
||||
|
||||
```cmd
|
||||
set DEBUG=*,-not_this
|
||||
```
|
||||
|
||||
Note that PowerShell uses different syntax to set environment variables.
|
||||
|
||||
```cmd
|
||||
$env:DEBUG = "*,-not_this"
|
||||
```
|
||||
|
||||
Then, run the program to be debugged as usual.
|
||||
|
||||
|
||||
## Namespace Colors
|
||||
|
||||
Every debug instance has a color generated for it based on its namespace name.
|
||||
This helps when visually parsing the debug output to identify which debug instance
|
||||
a debug line belongs to.
|
||||
|
||||
#### Node.js
|
||||
|
||||
In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
|
||||
the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
|
||||
otherwise debug will only use a small handful of basic colors.
|
||||
|
||||
<img width="521" src="https://user-images.githubusercontent.com/71256/29092181-47f6a9e6-7c3a-11e7-9a14-1928d8a711cd.png">
|
||||
|
||||
#### Web Browser
|
||||
|
||||
Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
|
||||
option. These are WebKit web inspectors, Firefox ([since version
|
||||
31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
|
||||
and the Firebug plugin for Firefox (any version).
|
||||
|
||||
<img width="524" src="https://user-images.githubusercontent.com/71256/29092033-b65f9f2e-7c39-11e7-8e32-f6f0d8e865c1.png">
|
||||
|
||||
|
||||
## Millisecond diff
|
||||
|
||||
When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
|
||||
|
||||
<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
|
||||
|
||||
When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
|
||||
|
||||
<img width="647" src="https://user-images.githubusercontent.com/71256/29091956-6bd78372-7c39-11e7-8c55-c948396d6edd.png">
|
||||
|
||||
|
||||
## Conventions
|
||||
|
||||
If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output.
|
||||
|
||||
## Wildcards
|
||||
|
||||
The `*` character may be used as a wildcard. Suppose for example your library has
|
||||
debuggers named "connect:bodyParser", "connect:compress", "connect:session",
|
||||
instead of listing all three with
|
||||
`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
|
||||
`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
|
||||
|
||||
You can also exclude specific debuggers by prefixing them with a "-" character.
|
||||
For example, `DEBUG=*,-connect:*` would include all debuggers except those
|
||||
starting with "connect:".
|
||||
|
||||
## Environment Variables
|
||||
|
||||
When running through Node.js, you can set a few environment variables that will
|
||||
change the behavior of the debug logging:
|
||||
|
||||
| Name | Purpose |
|
||||
|-----------|-------------------------------------------------|
|
||||
| `DEBUG` | Enables/disables specific debugging namespaces. |
|
||||
| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). |
|
||||
| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
|
||||
| `DEBUG_DEPTH` | Object inspection depth. |
|
||||
| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
|
||||
|
||||
|
||||
__Note:__ The environment variables beginning with `DEBUG_` end up being
|
||||
converted into an Options object that gets used with `%o`/`%O` formatters.
|
||||
See the Node.js documentation for
|
||||
[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
|
||||
for the complete list.
|
||||
|
||||
## Formatters
|
||||
|
||||
Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
|
||||
Below are the officially supported formatters:
|
||||
|
||||
| Formatter | Representation |
|
||||
|-----------|----------------|
|
||||
| `%O` | Pretty-print an Object on multiple lines. |
|
||||
| `%o` | Pretty-print an Object all on a single line. |
|
||||
| `%s` | String. |
|
||||
| `%d` | Number (both integer and float). |
|
||||
| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
|
||||
| `%%` | Single percent sign ('%'). This does not consume an argument. |
|
||||
|
||||
|
||||
### Custom formatters
|
||||
|
||||
You can add custom formatters by extending the `debug.formatters` object.
|
||||
For example, if you wanted to add support for rendering a Buffer as hex with
|
||||
`%h`, you could do something like:
|
||||
|
||||
```js
|
||||
const createDebug = require('debug')
|
||||
createDebug.formatters.h = (v) => {
|
||||
return v.toString('hex')
|
||||
}
|
||||
|
||||
// …elsewhere
|
||||
const debug = createDebug('foo')
|
||||
debug('this is hex: %h', new Buffer('hello world'))
|
||||
// foo this is hex: 68656c6c6f20776f726c6421 +0ms
|
||||
```
|
||||
|
||||
|
||||
## Browser Support
|
||||
|
||||
You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
|
||||
or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
|
||||
if you don't want to build it yourself.
|
||||
|
||||
Debug's enable state is currently persisted by `localStorage`.
|
||||
Consider the situation shown below where you have `worker:a` and `worker:b`,
|
||||
and wish to debug both. You can enable this using `localStorage.debug`:
|
||||
|
||||
```js
|
||||
localStorage.debug = 'worker:*'
|
||||
```
|
||||
|
||||
And then refresh the page.
|
||||
|
||||
```js
|
||||
a = debug('worker:a');
|
||||
b = debug('worker:b');
|
||||
|
||||
setInterval(function(){
|
||||
a('doing some work');
|
||||
}, 1000);
|
||||
|
||||
setInterval(function(){
|
||||
b('doing some work');
|
||||
}, 1200);
|
||||
```
|
||||
|
||||
|
||||
## Output streams
|
||||
|
||||
By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
|
||||
|
||||
Example [_stdout.js_](./examples/node/stdout.js):
|
||||
|
||||
```js
|
||||
var debug = require('debug');
|
||||
var error = debug('app:error');
|
||||
|
||||
// by default stderr is used
|
||||
error('goes to stderr!');
|
||||
|
||||
var log = debug('app:log');
|
||||
// set this namespace to log via console.log
|
||||
log.log = console.log.bind(console); // don't forget to bind to console!
|
||||
log('goes to stdout');
|
||||
error('still goes to stderr!');
|
||||
|
||||
// set all output to go via console.info
|
||||
// overrides all per-namespace log settings
|
||||
debug.log = console.info.bind(console);
|
||||
error('now goes to stdout via console.info');
|
||||
log('still goes to stdout, but via console.info now');
|
||||
```
|
||||
|
||||
## Checking whether a debug target is enabled
|
||||
|
||||
After you've created a debug instance, you can determine whether or not it is
|
||||
enabled by checking the `enabled` property:
|
||||
|
||||
```javascript
|
||||
const debug = require('debug')('http');
|
||||
|
||||
if (debug.enabled) {
|
||||
// do stuff...
|
||||
}
|
||||
```
|
||||
|
||||
You can also manually toggle this property to force the debug instance to be
|
||||
enabled or disabled.

# engine.io-parser
|
||||
|
||||
[](http://travis-ci.org/socketio/engine.io-parser)
|
||||
[](http://badge.fury.io/js/engine.io-parser)
|
||||
|
||||
This is the JavaScript parser for the engine.io protocol encoding,
|
||||
shared by both
|
||||
[engine.io-client](https://github.com/socketio/engine.io-client) and
|
||||
[engine.io](https://github.com/socketio/engine.io).
|
||||
|
||||
## How to use
|
||||
|
||||
### Standalone
|
||||
|
||||
The parser can encode/decode packets, payloads, and payloads as binary
|
||||
with the following methods: `encodePacket`, `decodePacket`, `encodePayload`,
|
||||
`decodePayload`, `encodePayloadAsBinary`, `decodePayloadAsBinary`.
|
||||
|
||||
The browser-side parser also includes `encodePayloadAsArrayBuffer` and `encodePayloadAsBlob`.
|
||||
|
||||
Example:
|
||||
|
||||
```js
|
||||
var parser = require('engine.io-parser');
|
||||
|
||||
var data = new Buffer(5);
|
||||
for (var i = 0; i < data.length; i++) { data[i] = i; }
|
||||
|
||||
parser.encodePacket({ type: 'message', data: data }, function(encoded) {
|
||||
var decodedData = parser.decodePacket(encoded); // { type: 'message', data: data }
|
||||
});
|
||||
```
|
||||
|
||||
### With browserify
|
||||
|
||||
Engine.IO Parser is a commonjs module, which means you can include it by using
|
||||
`require` on the browser and package using [browserify](http://browserify.org/):
|
||||
|
||||
1. install the parser package
|
||||
|
||||
```shell
|
||||
npm install engine.io-parser
|
||||
```
|
||||
|
||||
1. write your app code
|
||||
|
||||
```js
|
||||
var parser = require('engine.io-parser');
|
||||
|
||||
var testBuffer = new Int8Array(10);
|
||||
for (var i = 0; i < testBuffer.length; i++) testBuffer[i] = i;
|
||||
|
||||
var packets = [{ type: 'message', data: testBuffer.buffer }, { type: 'message', data: 'hello' }];
|
||||
|
||||
parser.encodePayload(packets, function(encoded) {
|
||||
parser.decodePayload(encoded,
|
||||
function(packet, index, total) {
|
||||
var isLast = index + 1 == total;
|
||||
if (!isLast) {
|
||||
var buffer = new Int8Array(packet.data); // testBuffer
|
||||
} else {
|
||||
var message = packet.data; // 'hello'
|
||||
}
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
1. build your app bundle
|
||||
|
||||
```bash
|
||||
$ browserify app.js > bundle.js
|
||||
```
|
||||
|
||||
1. include on your page
|
||||
|
||||
```html
|
||||
<script src="/path/to/bundle.js"></script>
|
||||
```
|
||||
|
||||
## Features
|
||||
|
||||
- Runs on browser and node.js seamlessly
|
||||
- Runs inside HTML5 WebWorker
|
||||
- Can encode and decode packets
|
||||
- Encodes from/to ArrayBuffer or Blob when in browser, and Buffer or ArrayBuffer in Node
|
||||
|
||||
## API
|
||||
|
||||
Note: `cb(type)` means the type is a callback function that contains a parameter of type `type` when called.
|
||||
|
||||
### Node
|
||||
|
||||
- `encodePacket`
|
||||
- Encodes a packet.
|
||||
- **Parameters**
|
||||
- `Object`: the packet to encode, has `type` and `data`.
|
||||
- `data`: can be a `String`, `Number`, `Buffer`, `ArrayBuffer`
|
||||
- `Boolean`: optional, binary support
|
||||
- `Function`: callback, returns the encoded packet (`cb(String)`)
|
||||
- `decodePacket`
|
||||
- Decodes a packet. Data also available as an ArrayBuffer if requested.
|
||||
- Returns data as `String` or (`Blob` on browser, `ArrayBuffer` on Node)
|
||||
- **Parameters**
|
||||
- `String` | `ArrayBuffer`: the packet to decode, has `type` and `data`
|
||||
- `String`: optional, the binary type
|
||||
|
||||
- `encodeBase64Packet`
|
||||
- Encodes a packet with binary data in a base64 string (`String`)
|
||||
- **Parameters**
|
||||
- `Object`: the packet to encode, has `type` and `data`
|
||||
- `Function`: callback, returns the base64 encoded message (`cb(String)`)
|
||||
- `decodeBase64Packet`
|
||||
- Decodes a packet encoded in a base64 string.
|
||||
- **Parameters**
|
||||
- `String`: the base64 encoded message
|
||||
- `String`: optional, the binary type
|
||||
|
||||
- `encodePayload`
|
||||
- Encodes multiple messages (payload).
|
||||
- If any contents are binary, they will be encoded as base64 strings. Base64
|
||||
encoded strings are marked with a b before the length specifier
|
||||
- **Parameters**
|
||||
- `Array`: an array of packets
|
||||
- `Boolean`: optional, binary support
|
||||
- `Function`: callback, returns the encoded payload (`cb(String)`)
|
||||
- `decodePayload`
|
||||
- Decodes data when a payload is maybe expected. Possible binary contents are
|
||||
decoded from their base64 representation.
|
||||
- **Parameters**
|
||||
- `String`: the payload
|
||||
- `String`: optional, the binary type
|
||||
- `Function`: callback, returns (cb(`Object`: packet, `Number`:packet index, `Number`:packet total))
|
||||
|
||||
- `encodePayloadAsBinary`
|
||||
- Encodes multiple messages (payload) as binary.
|
||||
- **Parameters**
|
||||
- `Array`: an array of packets
|
||||
- `Function`: callback, returns the encoded payload (`cb(Buffer)`)
|
||||
- `decodePayloadAsBinary`
|
||||
- Decodes data when a payload is maybe expected. Strings are decoded by
|
||||
interpreting each byte as a key code for entries marked to start with 0. See
|
||||
description of encodePayloadAsBinary.
|
||||
- **Parameters**
|
||||
- `Buffer`: the buffer
|
||||
- `String`: optional, the binary type

||||
- `Array`: an array of packets
|
||||
- `Function`: callback, returns the encoded payload (`cb(ArrayBuffer)`)
|
||||
- `encodePayloadAsBlob`
|
||||
- Encodes multiple messages (payload) as blob.
|
||||
- **Parameters**
|
||||
- `Array`: an array of packets
|
||||
- `Function`: callback, returns the encoded payload (`cb(Blob)`)
|
||||
|
||||
## Tests
|
||||
|
||||
Standalone tests can be run with `make test` which will run both node.js and browser tests.
|
||||
|
||||
Browser tests are run using [zuul](https://github.com/defunctzombie/zuul).
|
||||
(You must have zuul setup with a saucelabs account.)
|
||||
|
||||
You can run the tests locally using the following command:
|
||||
|
||||
```
|
||||
./node_modules/.bin/zuul --local 8080 -- test/index.js
|
||||
```
|
||||
|
||||
## Support
|
||||
|
||||
The support channels for `engine.io-parser` are the same as `socket.io`:
|
||||
- irc.freenode.net **#socket.io**
|
||||
- [Google Groups](http://groups.google.com/group/socket_io)
|
||||
- [Website](http://socket.io)
|
||||
|
||||
## Development

# ms
|
||||
|
||||
[](https://travis-ci.org/zeit/ms)
|
||||
[](https://zeit.chat/)
|
||||
|
||||
Use this package to easily convert various time formats to milliseconds.
|
||||
|
||||
## Examples
|
||||
|
||||
```js
|
||||
ms('2 days') // 172800000
|
||||
ms('1d') // 86400000
|
||||
ms('10h') // 36000000
|
||||
ms('2.5 hrs') // 9000000
|
||||
ms('2h') // 7200000
|
||||
ms('1m') // 60000
|
||||
ms('5s') // 5000
|
||||
ms('1y') // 31557600000
|
||||
ms('100') // 100
|
||||
```
|
||||
|
||||
### Convert from milliseconds
|
||||
|
||||
```js
|
||||
ms(60000) // "1m"
|
||||
ms(2 * 60000) // "2m"
|
||||
ms(ms('10 hours')) // "10h"
|
||||
```
|
||||
|
||||
### Time format written-out
|
||||
|
||||
```js
|
||||
ms(60000, { long: true }) // "1 minute"
|
||||
ms(2 * 60000, { long: true }) // "2 minutes"
|
||||
ms(ms('10 hours'), { long: true }) // "10 hours"
|
||||
```
|
||||
|
||||
## Features
|
||||
|
||||
- Works both in [node](https://nodejs.org) and in the browser.
|
||||
- If a number is supplied to `ms`, a string with a unit is returned.
|
||||
- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`).
|
||||
- If you pass a string with a number and a valid unit, the number of equivalent ms is returned.
|
||||
|
||||
## Caught a bug?
|
||||
|
||||
1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
|
||||
2. Link the package to the global module directory: `npm link`
|
||||
3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, node will now use your clone of ms!
|
||||
|
||||
As always, you can run the tests using: `npm test`

# ws: a Node.js WebSocket library
|
||||
|
||||
[](https://www.npmjs.com/package/ws)
|
||||
[](https://travis-ci.org/websockets/ws)
|
||||
[](https://ci.appveyor.com/project/lpinca/ws)
|
||||
[](https://coveralls.io/r/websockets/ws?branch=master)
|
||||
|
||||
ws is a simple to use, blazing fast, and thoroughly tested WebSocket client
|
||||
and server implementation.
|
||||
|
||||
Passes the quite extensive Autobahn test suite: [server][server-report],
|
||||
[client][client-report].
|
||||
|
||||
**Note**: This module does not work in the browser. The client in the docs is a
|
||||
reference to a back end with the role of a client in the WebSocket
|
||||
communication. Browser clients must use the native
|
||||
[`WebSocket`](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket) object.

## Protocol support
|
||||
|
||||
* **HyBi drafts 07-12** (Use the option `protocolVersion: 8`)
|
||||
* **HyBi drafts 13-17** (Current default, alternatively option `protocolVersion: 13`)
|
||||
|
||||
## Installing
|
||||
|
||||
```
|
||||
npm install --save ws
|
||||
```
|
||||
|
||||
### Opt-in for performance and spec compliance
|
||||
|
||||
There are 2 optional modules that can be installed along side with the ws
|
||||
module. These modules are binary addons which improve certain operations.
|
||||
Prebuilt binaries are available for the most popular platforms so you don't
|
||||
necessarily need to have a C++ compiler installed on your machine.
|
||||
|
||||
- `npm install --save-optional bufferutil`: Allows to efficiently perform
|
||||
operations such as masking and unmasking the data payload of the WebSocket
|
||||
frames.
|
||||
- `npm install --save-optional utf-8-validate`: Allows to efficiently check
|
||||
if a message contains valid UTF-8 as required by the spec.
|
||||
|
||||
## API docs
|
||||
|
||||
See [`/doc/ws.md`](./doc/ws.md) for Node.js-like docs for the ws classes.
|
||||
|
||||
## WebSocket compression
|
||||
|
||||
ws supports the [permessage-deflate extension][permessage-deflate] which
|
||||
enables the client and server to negotiate a compression algorithm and its
|
||||
parameters, and then selectively apply it to the data payloads of each
|
||||
WebSocket message.
|
||||
|
||||
The extension is disabled by default on the server and enabled by default on
|
||||
the client. It adds a significant overhead in terms of performance and memory
|
||||
consumption so we suggest to enable it only if it is really needed.
|
||||
|
||||
The client will only use the extension if it is supported and enabled on the
|
||||
server. To always disable the extension on the client set the
|
||||
`perMessageDeflate` option to `false`.
|
||||
|
||||
```js
|
||||
const WebSocket = require('ws');
|
||||
|
||||
const ws = new WebSocket('ws://www.host.com/path', {
|
||||
perMessageDeflate: false
|
||||
});
|
||||
```
|
||||
|
||||
## Usage examples
|
||||
|
||||
### Sending and receiving text data
|
||||
|
||||
```js
|
||||
const WebSocket = require('ws');
|
||||
|
||||
const ws = new WebSocket('ws://www.host.com/path');
|
||||
|
||||
ws.on('open', function open() {
|
||||
ws.send('something');
|
||||
});
|
||||
|
||||
ws.on('message', function incoming(data) {
|
||||
console.log(data);
|
||||
});
|
||||
```
|
||||
|
||||
### Sending binary data
|
||||
|
||||
```js
|
||||
const WebSocket = require('ws');
|
||||
|
||||
const ws = new WebSocket('ws://www.host.com/path');
|
||||
|
||||
ws.on('open', function open() {
|
||||
const array = new Float32Array(5);
|
||||
|
||||
for (var i = 0; i < array.length; ++i) {
|
||||
array[i] = i / 2;
|
||||
}
|
||||
|
||||
ws.send(array);
|
||||
});
|
||||
```
|
||||
|
||||
### Server example
|
||||
|
||||
```js
|
||||
const WebSocket = require('ws');
|
||||
|
||||
const wss = new WebSocket.Server({ port: 8080 });
|
||||
|
||||
wss.on('connection', function connection(ws) {
|
||||
ws.on('message', function incoming(message) {
|
||||
console.log('received: %s', message);
|
||||
});
|
||||
|
||||
ws.send('something');
|
||||
});
|
||||
```
|
||||
|
||||
### Broadcast example
|
||||
|
||||
```js
|
||||
const WebSocket = require('ws');
|
||||
|
||||
const wss = new WebSocket.Server({ port: 8080 });
|
||||
|
||||
// Broadcast to all.
|
||||
wss.broadcast = function broadcast(data) {
|
||||
wss.clients.forEach(function each(client) {
|
||||
if (client.readyState === WebSocket.OPEN) {
|
||||
client.send(data);
|
||||
}
|
||||
});
|
||||
};
|
||||
|
||||
wss.on('connection', function connection(ws) {
|
||||
ws.on('message', function incoming(data) {
|
||||
// Broadcast to everyone else.
|
||||
wss.clients.forEach(function each(client) {
|
||||
if (client !== ws && client.readyState === WebSocket.OPEN) {
|
||||
client.send(data);
|
||||
}
|
||||
});
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
### ExpressJS example
|
||||
|
||||
```js
|
||||
const express = require('express');
|
||||
const http = require('http');
|
||||
const url = require('url');
|
||||
const WebSocket = require('ws');
|
||||
|
||||
const app = express();
|
||||
|
||||
app.use(function (req, res) {
|
||||
res.send({ msg: "hello" });
|
||||
});
|
||||
|
||||
const server = http.createServer(app);
|
||||
const wss = new WebSocket.Server({ server });
|
||||
|
||||
wss.on('connection', function connection(ws, req) {
|
||||
const location = url.parse(req.url, true);
|
||||
// You might use location.query.access_token to authenticate or share sessions
|
||||
// or req.headers.cookie (see http://stackoverflow.com/a/16395220/151312)
|
||||
|
||||
ws.on('message', function incoming(message) {
|
||||
console.log('received: %s', message);
|
||||
});
|
||||
|
||||
ws.send('something');
|
||||
});
|
||||
|
||||
server.listen(8080, function listening() {
|
||||
console.log('Listening on %d', server.address().port);
|
||||
});
|
||||
```
|
||||
|
||||
### echo.websocket.org demo
|
||||
|
||||
```js
|
||||
const WebSocket = require('ws');
|
||||
|
||||
const ws = new WebSocket('wss://echo.websocket.org/', {
|
||||
origin: 'https://websocket.org'
|
||||
});
|
||||
|
||||
ws.on('open', function open() {
|
||||
console.log('connected');
|
||||
ws.send(Date.now());
|
||||
});
|
||||
|
||||
ws.on('close', function close() {
|
||||
console.log('disconnected');
|
||||
});
|
||||
|
||||
ws.on('message', function incoming(data) {
|
||||
console.log(`Roundtrip time: ${Date.now() - data} ms`);
|
||||
|
||||
setTimeout(function timeout() {
|
||||
ws.send(Date.now());
|
||||
}, 500);
|
||||
});
|
||||
```
|
||||
|
||||
### Other examples
|
||||
|
||||
For a full example with a browser client communicating with a ws server, see the
|
||||
examples folder.
|
||||
|
||||
Otherwise, see the test cases.
|
||||
|
||||
## Error handling best practices
|
||||
|
||||
```js
|
||||
// If the WebSocket is closed before the following send is attempted
|
||||
ws.send('something');
|
||||
|
||||
// Errors (both immediate and async write errors) can be detected in an optional
|
||||
// callback. The callback is also the only way of being notified that data has
|
||||
// actually been sent.
|
||||
ws.send('something', function ack(error) {
|
||||
// If error is not defined, the send has been completed, otherwise the error
|
||||
// object will indicate what failed.
|
||||
});
|
||||
|
||||
// Immediate errors can also be handled with `try...catch`, but **note** that
|
||||
// since sends are inherently asynchronous, socket write failures will *not* be
|
||||
// captured when this technique is used.
|
||||
try { ws.send('something'); }
|
||||
catch (e) { /* handle error */ }
|
||||
```
|
||||
|
||||
## FAQ
|
||||
|
||||
### How to get the IP address of the client?
|
||||
|
||||
The remote IP address can be obtained from the raw socket.
|
||||
|
||||
```js
|
||||
const WebSocket = require('ws');
|
||||
|
||||
const wss = new WebSocket.Server({ port: 8080 });
|
||||
|
||||
wss.on('connection', function connection(ws, req) {
|
||||
const ip = req.connection.remoteAddress;
|
||||
});
|
||||
```
|
||||
|
||||
When the server runs behind a proxy like NGINX, the de-facto standard is to use
|
||||
the `X-Forwarded-For` header.
|
||||
|
||||
```js
|
||||
wss.on('connection', function connection(ws, req) {
|
||||
const ip = req.headers['x-forwarded-for'];
|
||||
});
|
||||
```
|
||||
|
||||
### How to detect and close broken connections?
|
||||
|
||||
Sometimes the link between the server and the client can be interrupted in a
|
||||
way that keeps both the server and the client unaware of the broken state of the
|
||||
connection (e.g. when pulling the cord).
|
||||
|
||||
In these cases ping messages can be used as a means to verify that the remote
|
||||
endpoint is still responsive.
|
||||
|
||||
```js
|
||||
const WebSocket = require('ws');
|
||||
|
||||
const wss = new WebSocket.Server({ port: 8080 });
|
||||
|
||||
function heartbeat() {
|
||||
this.isAlive = true;
|
||||
}
|
||||
|
||||
wss.on('connection', function connection(ws) {
|
||||
ws.isAlive = true;
|
||||
ws.on('pong', heartbeat);
|
||||
});
|
||||
|
||||
const interval = setInterval(function ping() {
|
||||
wss.clients.forEach(function each(ws) {
|
||||
if (ws.isAlive === false) return ws.terminate();
|
||||
|
||||
ws.isAlive = false;
|
||||
ws.ping('', false, true);
|
||||
});
|
||||
}, 30000);
|
||||
```
|
||||
|
||||
Pong messages are automatically sent in response to ping messages as required
|
||||
by the spec.
|
||||
|
||||
### How to connect via a proxy?
|
||||
|
||||
Use a custom `http.Agent` implementation like [https-proxy-agent][] or
|
||||
[socks-proxy-agent][].
