# Embedding and Deploying noVNC Application
|
|
|
|
This document describes how to embed and deploy the noVNC application, which
|
|
includes settings and a full user interface. If you are looking for
|
|
documentation on how to use the core noVNC library in your own application,
|
|
then please see our [library documentation](LIBRARY.md).
|
|
|
|
## Files
|
|
|
|
The noVNC application consists of the following files and directories:
|
|
|
|
* `vnc.html` - The main page for the application and where users should go. It
|
|
is possible to rename this file.
|
|
|
|
* `app/` - Support files for the application. Contains code, images, styles and
|
|
translations.
|
|
|
|
* `core/` - The core noVNC library.
|
|
|
|
* `vendor/` - Third party support libraries used by the application and the
|
|
core library.
|
|
|
|
The most basic deployment consists of simply serving these files from a web
|
|
server and setting up a WebSocket proxy to the VNC server.
|
|
|
|
## Parameters
|
|
|
|
The noVNC application can be controlled by including certain settings in the
|
|
query string. Currently the following options are available:
|
|
|
|
* `autoconnect` - Automatically connect as soon as the page has finished
|
|
loading.
|
|
|
|
* `reconnect` - If noVNC should automatically reconnect if the connection is
|
|
dropped.
|
|
|
|
* `reconnect_delay` - How long to wait in milliseconds before attempting to
|
|
reconnect.
|
|
|
|
* `host` - The WebSocket host to connect to.
|
|
|
|
* `port` - The WebSocket port to connect to.
|
|
|
|
* `encrypt` - If TLS should be used for the WebSocket connection.
|
|
|
|
* `path` - The WebSocket path to use.
|
|
|
|
* `password` - The password sent to the server, if required.
|
|
|
|
* `repeaterID` - The repeater ID to use if a VNC repeater is detected.
|
|
|
|
* `shared` - If other VNC clients should be disconnected when noVNC connects.
|
|
|
|
* `bell` - If the keyboard bell should be enabled or not.
|
|
|
|
* `view_only` - If the remote session should be in non-interactive mode.
|
|
|
|
* `view_clip` - If the remote session should be clipped or use scrollbars if
|
|
it cannot fit in the browser.
|
|
|
|
* `resize` - How to resize the remote session if it is not the same size as
|
|
the browser window. Can be one of `off`, `scale` and `remote`.
|
|
|
|
* `logging` - The console log level. Can be one of `error`, `warn`, `info` or
|
|
`debug`.
|

|
## Pre-conversion of Modules
|
|
|
|
noVNC is written using ECMAScript 6 modules. Many of the major browsers support
|
|
these modules natively, but not all. By default the noVNC application includes
|
|
a script that can convert these modules to an older format as they are being
|
|
loaded. However this process can be slow and severely increases the load time
|
|
for the application.
|
|
|
|
It is possible to perform this conversion ahead of time, avoiding the extra
|
|
load times. To do this please follow these steps:
|
|
|
|
1. Install Node.js
|
|
2. Run `npm install` in the noVNC directory
|
|
3. Run `./utils/use_require.js --with-app --as commonjs`
|
|
|
|
This will produce a `build/` directory that includes everything needed to run
|
|
the noVNC application.
