# 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);
});
```
