# libwvnc

Overview about WVNC: [https://blog.lxsang.me/r/id/23](https://blog.lxsang.me/r/id/23)
|
||||
|
||||
**libwvnc** is the client side protocol API for my [Antd's **wvnc**](https://github.com/lxsang/antd-wvnc-plugin) server side plugin. It allows to acess VNC server from the web using websocket (via the **wvnc** server plugin).
|
||||
|
||||
Since the **wvnc** plugin offers data compression using JPEG, **wvnc.js** depends on the **libjpeg** package and **web worker** to speed up the data decoding process, thus speed up the screen rendering on HTML canvas.
|
||||
|
||||
|
||||
## Example
|
||||
It is straight forward to use the api:
|
||||
|
||||
Html code:
|
||||
|
||||
```html
|
||||
...
|
||||
<canvas id = "screen"></canvas>
|
||||
```
|
||||
|
||||
Javascript:
|
||||
|
||||
```javascript
|
||||
var args, client;
|
||||
args = {
|
||||
// the canvas element
|
||||
element: 'screen',
|
||||
// The websocket uri to the wvnc server side plugin
|
||||
ws: 'wss://localhost/wvnc',
|
||||
// the decoder worker
|
||||
libjpeg: 'path/to/jpg.js'
|
||||
};
|
||||
client = new WVNC(args);
|
||||
|
||||
// This function responds to a VNC server password request
|
||||
// should return a promise
|
||||
client.onpassword = function() {
|
||||
return new Promise(function(r, e) {
|
||||
return r('password');
|
||||
});
|
||||
};
|
||||
|
||||
// this function responds to the remote OS username and password request
|
||||
// should return a promise
|
||||
client.oncredential = function() {
|
||||
return new Promise(function(r, e) {
|
||||
return r('username', 'password');
|
||||
});
|
||||
};
|
||||
// event fired when a text is copied on
|
||||
// the remote computer
|
||||
client.oncopy = function(text) {
|
||||
console.log(text);
|
||||
};
|
||||
// init the WVNC client
|
||||
client.init()
|
||||
.then(function() {
|
||||
client.connect(
|
||||
// VNC server
|
||||
"192.168.1.20:5901",
|
||||
{
|
||||
// bits per pixel
|
||||
bbp: 32,
|
||||
// data compression flag
|
||||
// 1 is for both JPEG
|
||||
// 0 is for raw data
|
||||
flag: 1,
|
||||
// JPEG quality %
|
||||
quality: 50
|
||||
});
|
||||
})
|
||||
.catch(function(m, s) {
|
||||
return console.error(m, s);
|
||||
});
|
||||
```
