How to contribute to noVNC
==========================
We accept code via pull requests on GitHub. There are several guidelines that
we expect contributors submitting code requests to follow. If you have issues
following any of these guidelines, feel free to drop us a line by leaving a
comment in the code request or sending us an email.
Contributing Guidelines
-----------------------
* While we don't have an official coding style guide, please try to follow
the general coding style of the existing code.
** Use four spaces instead of tabs
** prefix private variables and functions with an `_`
* Please try to include unit tests for your code. For instance, if you
introduce a new encoding, add a test to `tests/test.rfb.js` under the
"Encoding Handlers" section (basically, input a small pattern in your
encoding and make sure the pattern gets displayed correctly). If you
fix a bug, try to add a unit test that would have caught that bug
(if possible -- some bugs, especially visual ones, are hard to test for).
* Squash your commits down in to a clean commit history. For instance, there
should not be "cleanup" commits where you fix issues in previous commits in
the same pull request. Before you go to commit, use `git rebase -i` to
squash these changes into the relevant commits. For instance, a good commit
history might look like "Added support for FOO encoding, Added support for
BAR message, Placed Button in UI to Trigger BAR" (where each comma denotes
a separate commit).
* Add both a title and description to your commit, if possible. Place more
detail on what you did in the description.
Running the unit tests
----------------------
There are two ways to run the unit tests. For both ways, you should first run
`npm install` (not as root).
The first way to run the tests is to run `npm test`. This will run all the
tests in the headless PhantomJS browser (which uses WebKit).
The second way to run the tests is using the `tests/run_from_console.js` file.
This way is a bit more flexible, and can provide more information about what
went wrong. To run all the tests, simply run `tests/run_from_console.js`.
To run a specific test file, you can use the `-t path/to/test/file.js` option.
If you wish to simply generate the HTML for the test, use the `-g` option, and
the path to the temporary HTML file will be written to standard out. To open
this file in your default browser automatically, pass the `-o` option as well.
More information can be found by passing the `--help` or `-h` option.
Thanks, and happy coding!

## noVNC: HTML5 VNC Client
[![Build Status](https://travis-ci.org/kanaka/noVNC.svg?branch=master)](https://travis-ci.org/kanaka/noVNC)
### Description
noVNC is a HTML5 VNC client that runs well in any modern browser
including mobile browsers (iPhone/iPad and Android).
Many companies/projects have integrated noVNC including [Ganeti Web
Manager](http://code.osuosl.org/projects/ganeti-webmgr),
[OpenStack](http://www.openstack.org),
[OpenNebula](http://opennebula.org/), and
[LibVNCServer](http://libvncserver.sourceforge.net). See [the Projects
and Companies wiki
page](https://github.com/kanaka/noVNC/wiki/ProjectsCompanies-using-noVNC)
for a more complete list with additional info and links.
### News/help/contact
Notable commits, announcements and news are posted to
<a href="http://www.twitter.com/noVNC">@noVNC</a>
If you are a noVNC developer/integrator/user (or want to be) please
join the <a
href="https://groups.google.com/forum/?fromgroups#!forum/novnc">noVNC
discussion group</a>
Bugs and feature requests can be submitted via [github
issues](https://github.com/kanaka/noVNC/issues). If you are looking
for a place to start contributing to noVNC, a good place to start
would be the issues that are marked as
["patchwelcome"](https://github.com/kanaka/noVNC/issues?labels=patchwelcome).
If you want to show appreciation for noVNC you could donate to a great
non-profits such as: [Compassion
International](http://www.compassion.com/), [SIL](http://www.sil.org),
[Habitat for Humanity](http://www.habitat.org), [Electronic Frontier
Foundation](https://www.eff.org/), [Against Malaria
Foundation](http://www.againstmalaria.com/), [Nothing But
Nets](http://www.nothingbutnets.net/), etc. Please tweet <a
href="http://www.twitter.com/noVNC">@noVNC</a> if you do.
### Features
* Supports all modern browsers including mobile (iOS, Android)
* Supported VNC encodings: raw, copyrect, rre, hextile, tight, tightPNG
* WebSocket SSL/TLS encryption (i.e. "wss://") support
* 24-bit true color and 8 bit colour mapped
* Supports desktop resize notification/pseudo-encoding
* Local or remote cursor
* Clipboard copy/paste
* Clipping or scolling modes for large remote screens
* Easy site integration and theming (3 example themes included)
* Licensed under the [MPL 2.0](http://www.mozilla.org/MPL/2.0/)
### Screenshots
Running in Chrome before and after connecting:
<img src="http://kanaka.github.com/noVNC/img/noVNC-5.png" width=400>&nbsp;<img src="http://kanaka.github.com/noVNC/img/noVNC-7.jpg" width=400>
See more screenshots <a href="http://kanaka.github.com/noVNC/screenshots.html">here</a>.
### Browser Requirements
* HTML5 Canvas (with createImageData): Chrome, Firefox 3.6+, iOS
Safari, Opera 11+, Internet Explorer 9+, etc.
* HTML5 WebSockets: For browsers that do not have builtin
WebSockets support, the project includes
<a href="http://github.com/gimite/web-socket-js">web-socket-js</a>,
a WebSockets emulator using Adobe Flash. iOS 4.2+ has built-in
WebSocket support.
* Fast Javascript Engine: this is not strictly a requirement, but
without a fast Javascript engine, noVNC might be painfully slow.
* See the more detailed [browser compatibility wiki page](https://github.com/kanaka/noVNC/wiki/Browser-support).
### Server Requirements
Unless you are using a VNC server with support for WebSockets
connections (such as
[x11vnc/libvncserver](http://libvncserver.sourceforge.net/),
[QEMU](http://www.qemu.org/), or
[PocketVNC](http://www.pocketvnc.com/blog/?page_id=866)), you need to
use a WebSockets to TCP socket proxy. There is a python proxy included
('websockify').
### Quick Start
* Use the launch script to start a mini-webserver and the WebSockets
proxy (websockify). The `--vnc` option is used to specify the location of
a running VNC server:
`./utils/launch.sh --vnc localhost:5901`
* Point your browser to the cut-and-paste URL that is output by the
launch script. Enter a password if the VNC server has one
configured. Hit the Connect button and enjoy!
### Other Pages
* [Encrypted Connections](https://github.com/kanaka/websockify/wiki/Encrypted-Connections). How to setup websockify so that you can use encrypted connections from noVNC.
* [Advanced Usage](https://github.com/kanaka/noVNC/wiki/Advanced-usage). Starting a VNC server, advanced websockify usage, etc.
* [Integrating noVNC](https://github.com/kanaka/noVNC/wiki/Integration) into existing projects.

* How to try
Assuming you have Web server (e.g. Apache) running at http://example.com/ .
- Download web_socket.rb from:
http://github.com/gimite/web-socket-ruby/tree/master
- Run sample Web Socket server (echo server) in example.com with: (#1)
$ ruby web-socket-ruby/samples/echo_server.rb example.com 10081
- If your server already provides socket policy file at port 843, modify the file to allow access to port 10081. Otherwise you can skip this step. See below for details.
- Publish the web-socket-js directory with your Web server (e.g. put it in ~/public_html).
- Change ws://localhost:10081 to ws://example.com:10081 in sample.html.
- Open sample.html in your browser.
- After "onopen" is shown, input something, click [Send] and confirm echo back.
#1: First argument of echo_server.rb means that it accepts Web Socket connection from HTML pages in example.com.
* Troubleshooting
If it doesn't work, try these:
1. Try Chrome and Firefox 3.x.
- It doesn't work on Chrome:
-- It's likely an issue of your code or the server. Debug your code as usual e.g. using console.log.
- It works on Chrome but it doesn't work on Firefox:
-- It's likely an issue of web-socket-js specific configuration (e.g. 3 and 4 below).
- It works on both Chrome and Firefox, but it doesn't work on your browser:
-- Check "Supported environment" section below. Your browser may not be supported by web-socket-js.
2. Add this line before your code:
WEB_SOCKET_DEBUG = true;
and use Developer Tools (Chrome/Safari) or Firebug (Firefox) to see if console.log outputs any errors.
3. Make sure you do NOT open your HTML page as local file e.g. file:///.../sample.html. web-socket-js doesn't work on local file. Open it via Web server e.g. http:///.../sample.html.
4. If you are NOT using web-socket-ruby as your WebSocket server, you need to place Flash socket policy file on your server. See "Flash socket policy file" section below for details.
5. Check if sample.html bundled with web-socket-js works.
6. Make sure the port used for WebSocket (10081 in example above) is not blocked by your server/client's firewall.
7. Install debugger version of Flash Player available here to see Flash errors:
http://www.adobe.com/support/flashplayer/downloads.html
* Supported environments
It should work on:
- Google Chrome 4 or later (just uses native implementation)
- Firefox 3.x, Internet Explorer 8 + Flash Player 9 or later
It may or may not work on other browsers such as Safari, Opera or IE 6. Patch for these browsers are appreciated, but I will not work on fixing issues specific to these browsers by myself.
* Flash socket policy file
This implementation uses Flash's socket, which means that your server must provide Flash socket policy file to declare the server accepts connections from Flash.
If you use web-socket-ruby available at
http://github.com/gimite/web-socket-ruby/tree/master
, you don't need anything special, because web-socket-ruby handles Flash socket policy file request. But if you already provide socket policy file at port 843, you need to modify the file to allow access to Web Socket port, because it precedes what web-socket-ruby provides.
If you use other Web Socket server implementation, you need to provide socket policy file yourself. See
http://www.lightsphere.com/dev/articles/flash_socket_policy.html
for details and sample script to run socket policy file server. node.js implementation is available here:
http://github.com/LearnBoost/Socket.IO-node/blob/master/lib/socket.io/transports/flashsocket.js
Actually, it's still better to provide socket policy file at port 843 even if you use web-socket-ruby. Flash always try to connect to port 843 first, so providing the file at port 843 makes startup faster.
* Cookie considerations
Cookie is sent if Web Socket host is the same as the origin of JavaScript. Otherwise it is not sent, because I don't know way to send right Cookie (which is Cookie of the host of Web Socket, I heard).
Note that it's technically possible that client sends arbitrary string as Cookie and any other headers (by modifying this library for example) once you place Flash socket policy file in your server. So don't trust Cookie and other headers if you allow connection from untrusted origin.
* Proxy considerations
The WebSocket spec (http://tools.ietf.org/html/draft-hixie-thewebsocketprotocol) specifies instructions for User Agents to support proxied connections by implementing the HTTP CONNECT method.
The AS3 Socket class doesn't implement this mechanism, which renders it useless for the scenarios where the user trying to open a socket is behind a proxy.
The class RFC2817Socket (by Christian Cantrell) effectively lets us implement this, as long as the proxy settings are known and provided by the interface that instantiates the WebSocket. As such, if you want to support proxied conncetions, you'll have to supply this information to the WebSocket constructor when Flash is being used. One way to go about it would be to ask the user for proxy settings information if the initial connection fails.
* How to host HTML file and SWF file in different domains
By default, HTML file and SWF file must be in the same domain. You can follow steps below to allow hosting them in different domain.
WARNING: If you use the method below, HTML files in ANY domains can send arbitrary TCP data to your WebSocket server, regardless of configuration in Flash socket policy file. Arbitrary TCP data means that they can even fake request headers including Origin and Cookie.
- Unzip WebSocketMainInsecure.zip to extract WebSocketMainInsecure.swf.
- Put WebSocketMainInsecure.swf on your server, instead of WebSocketMain.swf.
- In JavaScript, set WEB_SOCKET_SWF_LOCATION to URL of your WebSocketMainInsecure.swf.

## WebSockets Proxy/Bridge
Websockify has been forked out into its own project. `launch.sh` wil
automatically download it here if it is not already present and not
installed as system-wide.
For more detailed description and usage information please refer to
the [websockify README](https://github.com/kanaka/websockify/blob/master/README.md).
The other versions of websockify (C, Node.js) and the associated test
programs have been moved to
[websockify](https://github.com/kanaka/websockify). Websockify was
formerly named wsproxy.

noVNC is a browser based VNC client implemented using HTML5 Canvas

support (such as <a href="http://libvncserver.sourceforge.net/">libvncserver</a>)
or you will need to use
<a href="https://github.com/kanaka/websockify">websockify</a>
to bridge between your browser and VNC server. See the noVNC
<a href="https://github.com/kanaka/noVNC">README</a>
