0.3.4
=====
* Mentioned njoyce's fork of sockjs-gevent.
* #90 - Don't catch onbeforeunload event - it breaks javascript://
links in IE.
* IE mangles 204 response code for 1223 on ajax, see:
http://bugs.jquery.com/ticket/1450
* Make `new` optional for SockJS constructor (via substack).
* It is impossible to cancel JSONP polling request - compensate for that.
* Refactored EventEmitter prototype (used only internally)
* #66 - Failure to post data to /xhr_send should kill the session
0.3.2
=====
* #77 - Getting /info on modern browsers when html is served from
file:// urls was broken.
0.3.1
=====
* #61 - Meteor guys found that we unintentionally catch "onopen" errors.
* #63 - Meteorjs guys found that xhr-streaming on Safari sometimes
left busy cursor running.
* Increased allowed time for websocket transport (from 1 rtt to 2),
this should make ws transport more reliable over SSL, at the cost
of slightly longer connection time for users with blocked ws.
* #57 - previous fix didn't really work, sockjs-client still left
a mess in browsers history when using iframe transports. This
is fixed now.
* #60 - Opera 12 (next) claims to do AJAX2 / CORS, but can't
do xhr-streaming.
* #58 - onunload test sometimes failed on Safari on windows
* Updated readme WRT websocket protocols
* Updated readme WRT deployments on heroku
* Add minimalistic license block to every source file.
0.3.0
=====
* Temporarily disabled iframe tests - they are failing unpredictably.
* #57 - pointing an iframe to "about:blank" during cleanup caused
Opera to messup history.
* #55 - Improved iframe abstraction (reduced a possible mem leak)
* Refactored AJAX abstractions, for better CORS handing - again.
* Add additional parent origin security check to an iframe.
* Urls with hashes or query strings can't be passed to SockJS.
* #18 - Mention workaround for Firefox ESC key issue
* #53 - AMD compliance
* sockjs/sockjs-protocol#28 - always use square brackets for
websocket frames
* #51 - initial support for IE10 - try XHR before XDR
* #28 - handle onunload / onbeforeunload in a more robust fashion
* #49 - support SockJS-client being used from files served from
file:// urls.
0.2.1
=====
* "smoke-latency.html" test was unnecesairly sending too much data.
* Bumped core dependencies (coffee-script and uglify-js)
* Minor updates to the README, few cosmetic changes in the code.
0.2.0
=====
* The API had changed - use `protocols_whitelist` option instead of
passing an array of protocols as a second argument to SockJS constructor.
* Dropped 'chunking-test' functionality and replace it with 'info'.
* Rewritten protocol-choosing alogirthm, see "utils.detectProtocols" method.
* Use dynamic protocol timeouts based on RTT, not hardcoded 5 seconds
* #34 - Don't ever reuse `session_id`, especially when trying
fallback protocols.
* The test server got moved from SockJS-client to SockJS-node.
* Don't test unicode surrogates - it can't work in some environments.
* XHR/XDR helpers were rewritten, ajax transports were simplified.
* Added a domain check in the iframe to improve security.
* SockJS will now trigger 1002 error if there is a problem during handshake
instead of 2000 error.
* Smoke-throughput test is renamed to smoke-latency.
0.1.2
=====
* #29 - Allow all unicode characters to be send over SockJS.
* #15 - SockJS should now work fine even if the connection is started
in HEAD, before BODY is loaded.
* #28 - In rare circumstances WebSocket connection can be left intact
after the page is unloaded in FireFox.
* Updated scripts to work with Node 0.6.
* Initial work to do better QUnit testing.
* Updated the minifying script (always escape unicode chars, remove
trailing comment).
* Use string instead of array of chars (utils.js:random_number_string).
0.1.1
=====
* #21 Get JsonP transport working on IE9 (Vladimir Dronnikov).
* #26 Emit heartbeat event.
* #27 Include license inline.
0.1.0
=====
* SockJS-client can only send UTF-8 encodable strings. Previously we
took advantage of rich data structures and automatically
json-encoded them, but this got removed. Now, all data passed to
`send` will be converted to string. This is also how native
* `status` property on `EventClose` is renamed to `code`
as per Websocket API
WebSockets behave.
* The test server was updated to new `sockjs-node` API
* Fixed problem with Jsonp-polling transport on IE9
* Repository was moved - updated links.
0.0.4
=====
* All transports were refactored, some transports were introduced:
htmlfile and separate xhr-streaming.
* Added logic to detect support for http chunking, and thus a
possibility to rule out streaming transports before running them.
* Added 'cookie' option, useful for cookie-based load balancing
(currently, it make a difference only for IE).
* Added hack to prevent EventSource from crashing Safari and Chrome.
* Loads and loads of other small and medium changes.
0.0.2
=====
* Initial support for JSESSIONID based load balancing. Currently
doesn't play nicely with IE XDomainRequest transport.
0.0.1
=====
* Initial release.

SockJS is a browser JavaScript library that provides a WebSocket-like
object. SockJS gives you a coherent, cross-browser, Javascript API
which creates a low latency, full duplex, cross-domain communication
channel between the browser and the web server.
Under the hood SockJS tries to use native WebSockets first. If that
fails it can use a variety of browser-specific transport protocols and
presents them through WebSocket-like abstractions.
SockJS is intended to work for all modern browsers and in environments
which don't support the WebSocket protocol -- for example, behind restrictive
corporate proxies.
SockJS-client does require a server counterpart:
* [SockJS-node](https://github.com/sockjs/sockjs-node) is a SockJS
server for Node.js.
Philosophy:
* The API should follow
[HTML5 Websockets API](https://www.w3.org/TR/websockets/) as
closely as possible.
* All the transports must support cross domain connections out of the
box. It's possible and recommended to host a SockJS server on a
different server than your main web site.
* There is support for at least one streaming protocol for every
major browser.
* Streaming transports should work cross-domain and
should support cookies (for cookie-based sticky sessions).
* Polling transports are used as a fallback for old browsers and
hosts behind restrictive proxies.
* Connection establishment should be fast and lightweight.
* No Flash inside (no need to open port 843 - which doesn't work
through proxies, no need to host 'crossdomain.xml', no need
[to wait for 3 seconds](https://github.com/gimite/web-socket-js/issues/49)
in order to detect problems)

Getting Started
-------
SockJS mimics the [WebSockets API](https://www.w3.org/TR/websockets/),
but instead of `WebSocket` there is a `SockJS` Javascript object.
First, you need to load the SockJS JavaScript library. For example, you can
put that in your HTML head:
```html
<script src="https://cdn.jsdelivr.net/npm/sockjs-client@1/dist/sockjs.min.js"></script>
```
After the script is loaded you can establish a connection with the
SockJS server. Here's a simple example:
```javascript
var sock = new SockJS('https://mydomain.com/my_prefix');
sock.onopen = function() {
console.log('open');
sock.send('test');
};
sock.onmessage = function(e) {
console.log('message', e.data);
sock.close();
};
sock.onclose = function() {
console.log('close');
};
```
SockJS-client API
-----------------
### SockJS class
Similar to the 'WebSocket' API, the 'SockJS' constructor takes one, or more arguments:
```javascript
var sockjs = new SockJS(url, _reserved, options);
```
`url` may contain a query string, if one is desired.
Where `options` is a hash which can contain:
* **server (string)**
String to append to url for actual data connection. Defaults to a random 4 digit number.
* **transports (string OR array of strings)**
Sometimes it is useful to disable some fallback transports. This
option allows you to supply a list transports that may be used by
SockJS. By default all available transports will be used.
* **sessionId (number OR function)**
Both client and server use session identifiers to distinguish connections.
If you specify this option as a number, SockJS will use its random string
generator function to generate session ids that are N-character long
(where N corresponds to the number specified by **sessionId**).
When you specify this option as a function, the function must return a
randomly generated string. Every time SockJS needs to generate a session
id it will call this function and use the returned string directly.
If you don't specify this option, the default is to use the default random
string generator to generate 8-character long session ids.
Although the 'SockJS' object tries to emulate the 'WebSocket'
behaviour, it's impossible to support all of its features. An
important SockJS limitation is the fact that you're not allowed to
open more than one SockJS connection to a single domain at a time.
This limitation is caused by an in-browser limit of outgoing
connections - usually [browsers don't allow opening more than two
outgoing connections to a single domain](https://stackoverflow.com/questions/985431/max-parallel-http-connections-in-a-browser). A single SockJS session
requires those two connections - one for downloading data, the other for
sending messages. Opening a second SockJS session at the same time
would most likely block, and can result in both sessions timing out.
Opening more than one SockJS connection at a time is generally a
bad practice. If you absolutely must do it, you can use
multiple subdomains, using a different subdomain for every
SockJS connection.
Supported transports, by browser (html served from http:// or https://)
-----------------------------------------------------------------------
_Browser_ | _Websockets_ | _Streaming_ | _Polling_
----------------|------------------|-------------|-------------------
IE 6, 7 | no | no | jsonp-polling
IE 8, 9 (cookies=no) | no | xdr-streaming &dagger; | xdr-polling &dagger;
IE 8, 9 (cookies=yes)| no | iframe-htmlfile | iframe-xhr-polling
IE 10 | rfc6455 | xhr-streaming | xhr-polling
Chrome 6-13 | hixie-76 | xhr-streaming | xhr-polling
Chrome 14+ | hybi-10 / rfc6455| xhr-streaming | xhr-polling
Firefox <10 | no &Dagger; | xhr-streaming | xhr-polling
Firefox 10+ | hybi-10 / rfc6455| xhr-streaming | xhr-polling
Safari 5.x | hixie-76 | xhr-streaming | xhr-polling
Safari 6+ | rfc6455 | xhr-streaming | xhr-polling
Opera 10.70+ | no &Dagger; | iframe-eventsource | iframe-xhr-polling
Opera 12.10+ | rfc6455 | xhr-streaming | xhr-polling
Konqueror | no | no | jsonp-polling
* **&dagger;**: IE 8+ supports [XDomainRequest][^9], which is
essentially a modified AJAX/XHR that can do requests across
domains. But unfortunately it doesn't send any cookies, which
makes it inappropriate for deployments when the load balancer uses
JSESSIONID cookie to do sticky sessions.
* **&Dagger;**: Firefox 4.0 and Opera 11.00 and shipped with disabled
Websockets "hixie-76". They can still be enabled by manually
changing a browser setting.
Supported transports, by browser (html served from file://)
-----------------------------------------------------------
Sometimes you may want to serve your html from "file://" address - for
development or if you're using PhoneGap or similar technologies. But
due to the Cross Origin Policy files served from "file://" have no
Origin, and that means some of SockJS transports won't work. For this
reason the SockJS transport table is different than usually, major
differences are:
_Browser_ | _Websockets_ | _Streaming_ | _Polling_
----------------|---------------|--------------------|-------------------
IE 8, 9 | same as above | iframe-htmlfile | iframe-xhr-polling
Other | same as above | iframe-eventsource | iframe-xhr-polling
Supported transports, by name
-----------------------------
_Transport_ | _References_
---------------------|---------------
websocket (rfc6455) | [rfc 6455][^10]
websocket (hixie-76) | [draft-hixie-thewebsocketprotocol-76][^1]
websocket (hybi-10) | [draft-ietf-hybi-thewebsocketprotocol-10][^2]
xhr-streaming | Transport using [Cross domain XHR][^5] [streaming][^7] capability (readyState=3).
xdr-streaming | Transport using [XDomainRequest][^9] [streaming][^7] capability (readyState=3).

Connecting to SockJS without the client
---------------------------------------
Although the main point of SockJS is to enable browser-to-server
connectivity, it is possible to connect to SockJS from an external
application. Any SockJS server complying with 0.3 protocol does
support a raw WebSocket url. The raw WebSocket url for the test server
looks like:
* ws://localhost:8081/echo/websocket
You can connect any WebSocket RFC 6455 compliant WebSocket client to
this url. This can be a command line client, external application,
third party code or even a browser (though I don't know why you would
want to do so).
Deployment
----------
You should use a version of sockjs-client
that supports the protocol used by your server. For example:
```html
<script src="https://cdn.jsdelivr.net/npm/sockjs-client@1/dist/sockjs.min.js"></script>
```
For server-side deployment tricks, especially about load balancing and
session stickiness, take a look at the
[SockJS-node readme](https://github.com/sockjs/sockjs-node#readme).
Development and testing
-----------------------
SockJS-client needs [node.js](https://nodejs.org/) for running a test
server and JavaScript minification. If you want to work on
SockJS-client source code, checkout the git repo and follow these
steps:
cd sockjs-client
npm install
To generate JavaScript, run:
gulp browserify
To generate minified JavaScript, run:
gulp browserify:min
Both commands output into the `build` directory.
### Testing
Once you've compiled the SockJS-client you may want to check if your changes
pass all the tests.
npm run test:browser_local
This will start [zuul](https://github.com/defunctzombie/zuul) and a test support server. Open the browser to [http://localhost:9090/_zuul](http://localhost:9090/_zuul) and watch the tests run.
Browser Quirks
--------------
There are various browser quirks which we don't intend to address:
* Pressing ESC in Firefox, before Firefox 20, closes the SockJS connection. For a workaround
and discussion see [#18](https://github.com/sockjs/sockjs-client/issues/18).
* `jsonp-polling` transport will show a "spinning wheel" (aka. "busy indicator")
when sending data.
* You can't open more than one SockJS connection to one domain at the
same time due to [the browser's limit of concurrent connections](https://stackoverflow.com/questions/985431/max-parallel-http-connections-in-a-browser)
(this limit is not counting native WebSocket connections).
* Although SockJS is trying to escape any strange Unicode characters
(even invalid ones - [like surrogates \xD800-\xDBFF](https://en.wikipedia.org/wiki/Mapping_of_Unicode_characters#Surrogates) or [\xFFFE and \xFFFF](https://en.wikipedia.org/wiki/Unicode#Character_General_Category))
it's advisable to use only valid characters. Using invalid
characters is a bit slower, and may not work with SockJS servers
that have proper Unicode support.
* Having a global function called `onmessage` or such is probably a
bad idea, as it could be called by the built-in `postMessage` API.
* From SockJS' point of view there is nothing special about
SSL/HTTPS. Connecting between unencrypted and encrypted sites
should work just fine.
* Although SockJS does its best to support both prefix and cookie based
sticky sessions, the latter may not work well cross-domain with
browsers that don't accept third-party cookies by default (Safari).
In order to get around this make sure you're connecting to SockJS
from the same parent domain as the main site. For example
'sockjs.a.com' is able to set cookies if you're connecting from
'www.a.com' or 'a.com'.
* Trying to connect from secure "https://" to insecure "http://" is
not a good idea. The other way around should be fine.
* Long polling is known to cause problems on Heroku, but a
[workaround for SockJS is available](https://github.com/sockjs/sockjs-node/issues/57#issuecomment-5242187).
* SockJS [websocket transport is more stable over SSL](https://github.com/sockjs/sockjs-client/issues/94). If
you're a serious SockJS user then consider using SSL
([more info](https://www.ietf.org/mail-archive/web/hybi/current/msg01605.html)).

# faye-websocket [![Build status](https://secure.travis-ci.org/faye/faye-websocket-node.svg)](http://travis-ci.org/faye/faye-websocket-node)
This is a general-purpose WebSocket implementation extracted from the
[Faye](http://faye.jcoglan.com) project. It provides classes for easily building
WebSocket servers and clients in Node. It does not provide a server itself, but
rather makes it easy to handle WebSocket connections within an existing
[Node](https://nodejs.org/) application. It does not provide any abstraction
other than the standard [WebSocket
API](https://html.spec.whatwg.org/multipage/comms.html#network).
It also provides an abstraction for handling
[EventSource](https://html.spec.whatwg.org/multipage/comms.html#server-sent-events)
connections, which are one-way connections that allow the server to push data to
the client. They are based on streaming HTTP responses and can be easier to access
via proxies than WebSockets.
## Installation
```
$ npm install faye-websocket
```
## Handling WebSocket connections in Node
You can handle WebSockets on the server side by listening for HTTP Upgrade
requests, and creating a new socket for the request. This socket object exposes
the usual WebSocket methods for receiving and sending messages. For example this
is how you'd implement an echo server:
```js
var WebSocket = require('faye-websocket'),
http = require('http');
var server = http.createServer();
server.on('upgrade', function(request, socket, body) {
if (WebSocket.isWebSocket(request)) {
var ws = new WebSocket(request, socket, body);
ws.on('message', function(event) {
ws.send(event.data);
});
ws.on('close', function(event) {
console.log('close', event.code, event.reason);
ws = null;
});
}
});
server.listen(8000);
```
`WebSocket` objects are also duplex streams, so you could replace the
`ws.on('message', ...)` line with:
```js
ws.pipe(ws);
```
Note that under certain circumstances (notably a draft-76 client connecting
through an HTTP proxy), the WebSocket handshake will not be complete after you
call `new WebSocket()` because the server will not have received the entire
handshake from the client yet. In this case, calls to `ws.send()` will buffer
the message in memory until the handshake is complete, at which point any
buffered messages will be sent to the client.
If you need to detect when the WebSocket handshake is complete, you can use the
`onopen` event.
If the connection's protocol version supports it, you can call `ws.ping()` to
send a ping message and wait for the client's response. This method takes a
message string, and an optional callback that fires when a matching pong message
is received. It returns `true` if and only if a ping message was sent. If the
client does not support ping/pong, this method sends no data and returns
`false`.
```js
ws.ping('Mic check, one, two', function() {
// fires when pong is received
});
```
## Using the WebSocket client
The client supports both the plain-text `ws` protocol and the encrypted `wss`
protocol, and has exactly the same interface as a socket you would use in a web
browser. On the wire it identifies itself as `hybi-13`.
```js
var WebSocket = require('faye-websocket'),
ws = new WebSocket.Client('ws://www.example.com/');
ws.on('open', function(event) {
console.log('open');
ws.send('Hello, world!');
});
ws.on('message', function(event) {
console.log('message', event.data);
});
ws.on('close', function(event) {
console.log('close', event.code, event.reason);
ws = null;
});
```
The WebSocket client also lets you inspect the status and headers of the
handshake response via its `statusCode` and `headers` properties.
To connect via a proxy, set the `proxy` option to the HTTP origin of the proxy,
including any authorization information, custom headers and TLS config you
require. Only the `origin` setting is required.
```js
var ws = new WebSocket.Client('ws://www.example.com/', [], {
proxy: {
origin: 'http://username:password@proxy.example.com',
headers: {'User-Agent': 'node'},
tls: {cert: fs.readFileSync('client.crt')}
}
});
```
The `tls` value is an object that will be passed to
[`tls.connect()`](https://nodejs.org/api/tls.html#tls_tls_connect_options_callback).
## Subprotocol negotiation
The WebSocket protocol allows peers to select and identify the application
protocol to use over the connection. On the client side, you can set which
protocols the client accepts by passing a list of protocol names when you
construct the socket:
```js
var ws = new WebSocket.Client('ws://www.example.com/', ['irc', 'amqp']);
```
On the server side, you can likewise pass in the list of protocols the server
supports after the other constructor arguments:
```js
var ws = new WebSocket(request, socket, body, ['irc', 'amqp']);
```
If the client and server agree on a protocol, both the client- and server-side
socket objects expose the selected protocol through the `ws.protocol` property.
## Protocol extensions
faye-websocket is based on the
[websocket-extensions](https://github.com/faye/websocket-extensions-node)
framework that allows extensions to be negotiated via the
`Sec-WebSocket-Extensions` header. To add extensions to a connection, pass an
array of extensions to the `:extensions` option. For example, to add
[permessage-deflate](https://github.com/faye/permessage-deflate-node):
```js
var deflate = require('permessage-deflate');
var ws = new WebSocket(request, socket, body, [], {extensions: [deflate]});
```
## Initialization options
Both the server- and client-side classes allow an options object to be passed in
at initialization time, for example:
```js
var ws = new WebSocket(request, socket, body, protocols, options);
var ws = new WebSocket.Client(url, protocols, options);
```
`protocols` is an array of subprotocols as described above, or `null`.
`options` is an optional object containing any of these fields:
- `extensions` - an array of
[websocket-extensions](https://github.com/faye/websocket-extensions-node)
compatible extensions, as described above
- `headers` - an object containing key-value pairs representing HTTP headers to
be sent during the handshake process
- `maxLength` - the maximum allowed size of incoming message frames, in bytes.
The default value is `2^26 - 1`, or 1 byte short of 64 MiB.
- `ping` - an integer that sets how often the WebSocket should send ping frames,
measured in seconds
The client accepts some additional options:
- `proxy` - settings for a proxy as described above
- `net` - an object containing settings for the origin server that will be
passed to
[`net.connect()`](https://nodejs.org/api/net.html#net_socket_connect_options_connectlistener)
- `tls` - an object containing TLS settings for the origin server, this will be
passed to
[`tls.connect()`](https://nodejs.org/api/tls.html#tls_tls_connect_options_callback)
- `ca` - (legacy) a shorthand for passing `{tls: {ca: value}}`
## WebSocket API
Both server- and client-side `WebSocket` objects support the following API.
- **`on('open', function(event) {})`** fires when the socket connection is
established. Event has no attributes.
- **`on('message', function(event) {})`** fires when the socket receives a
message. Event has one attribute, **`data`**, which is either a `String` (for
text frames) or a `Buffer` (for binary frames).
- **`on('error', function(event) {})`** fires when there is a protocol error due
to bad data sent by the other peer. This event is purely informational, you do
not need to implement error recover.
- **`on('close', function(event) {})`** fires when either the client or the
server closes the connection. Event has two optional attributes, **`code`**
and **`reason`**, that expose the status code and message sent by the peer
that closed the connection.
- **`send(message)`** accepts either a `String` or a `Buffer` and sends a text
or binary message over the connection to the other peer.
- **`ping(message, function() {})`** sends a ping frame with an optional message
and fires the callback when a matching pong is received.
- **`close(code, reason)`** closes the connection, sending the given status code
and reason text, both of which are optional.
- **`version`** is a string containing the version of the `WebSocket` protocol
the connection is using.
- **`protocol`** is a string (which may be empty) identifying the subprotocol
the socket is using.
## Handling EventSource connections in Node
EventSource connections provide a very similar interface, although because they
only allow the server to send data to the client, there is no `onmessage` API.
EventSource allows the server to push text messages to the client, where each
message has an optional event-type and ID.
```js
var WebSocket = require('faye-websocket'),
EventSource = WebSocket.EventSource,
http = require('http');
var server = http.createServer();
server.on('request', function(request, response) {
if (EventSource.isEventSource(request)) {
var es = new EventSource(request, response);
console.log('open', es.url, es.lastEventId);
// Periodically send messages
var loop = setInterval(function() { es.send('Hello') }, 1000);
es.on('close', function() {
clearInterval(loop);
es = null;
});
} else {
// Normal HTTP request
response.writeHead(200, {'Content-Type': 'text/plain'});
response.end('Hello');
}
});
server.listen(8000);
```
The `send` method takes two optional parameters, `event` and `id`. The default
event-type is `'message'` with no ID. For example, to send a `notification`
event with ID `99`:
```js
es.send('Breaking News!', {event: 'notification', id: '99'});
```
The `EventSource` object exposes the following properties:
- **`url`** is a string containing the URL the client used to create the
EventSource.
- **`lastEventId`** is a string containing the last event ID received by the
client. You can use this when the client reconnects after a dropped connection
to determine which messages need resending.
When you initialize an EventSource with ` new EventSource()`, you can pass
configuration options after the `response` parameter. Available options are:
- **`headers`** is an object containing custom headers to be set on the
EventSource response.
- **`retry`** is a number that tells the client how long (in seconds) it should
wait after a dropped connection before attempting to reconnect.
- **`ping`** is a number that tells the server how often (in seconds) to send
'ping' packets to the client to keep the connection open, to defeat timeouts
set by proxies. The client will ignore these messages.
For example, this creates a connection that allows access from any origin, pings
every 15 seconds and is retryable every 10 seconds if the connection is broken:
```js
var es = new EventSource(request, response, {
headers: {'Access-Control-Allow-Origin': '*'},
ping: 15,
retry: 10
});
```
You can send a ping message at any time by calling `es.ping()`. Unlike
WebSocket, the client does not send a response to this; it is merely to send
some data over the wire to keep the connection alive.
