vlitejs
(pronounced /viːlaɪt/) is a fast and lightweight JavaScript library for customizing video and audio player. Written in native JavaScript without dependency, it is built around an API of providers and plugins to extend these capabilities and keep the core with the minimal functionalities.
HTML5 video and audio players are automatically included. Other providers like Youtube or Vimeo can be loaded on demand with the Provider API. Plugins uses the same logic and can be loaded on demand by the Plugin API. Others providers and plugins can be created and loaded by the library.
Why vLitejs?
- If you are concerned about your app's loading performance, this library makes sense as it is extremely lightweight compared to the competition (only 6 KB).
- It is quite rare to need to be compatible with HTML5, Youtube, Vimeo and Dailymotion at the same time. The library contains by default only HTML5 capabilities and exposed the Provider API to extend capabilities with other providers.
- If you need specific behaviors, the plugin API allows to extends the library capabilities.
- If you need to create a video or audio player with a custom skin harmonized for all web browsers.

Import vlitejs
styleheet and the JavaScript library as an ES6 modules.
import 'vlitejs/vlite.css';
import Vlitejs from 'vlitejs';

The second arguments of the contructor is an optional object with the following parameters:
| Arguments | Type | Default | Description |
| ---------- | :--------------: | :-------: | -------------------------------------------------------------------- |
| options
| Object
| {}
| Player options |
| onReady
| Function\|null

The
autoplay
parameter automatically activates themuted
option because the API can only be initiated by a user gesture (see Autoplay policy changes).
Example of customization for the autoHide
and the poster
options.
new Vlitejs('#player', {
options: {
autoHide: true,
poster: '/path/to/poster.jpg'
}
});
Player ready
The callback function onReady
is automatically executed when the player is ready. The HTML5 video and audio listen to the canplay|loadedmetadata
event. The Youtube, Vimeo and Dailymotion provider listen to the onready
event returned by their API.
The function exposes the player
parameter as the player instance. You can use it to interact with the player instance and the player methods.
Example of a player muted
when ready:
new Vlitejs('#player', {
onReady: function (player) {
player.mute();
}
});
Note The
onReady
function can also be written with an arrow function.
Events
vlitejs
exposes the following native Event
on the .v-vlite
element. Events are standardized for all providers. Each plugin has its own events which are detailed in their dedicated documentation.
| Event Type | Description |

| play
| Sent when the playback state is no longer paused, after the play method or the autoplay |
| pause
| Sent when the playback state is changed to paused |
| progress
| Sent periodically to inform interested parties of progress downloading the media. |
| timeupdate
| Sent when the currentTime
of the media has changed |
| volumechange
| Sent when audio volume changes |
| enterfullscreen
¹ | Sent when the video switches to fullscreen mode |
| exitfullscreen
¹ | Sent when the video exits fullscreen mode |
| ended
| Sent when playback completes |
Note > ¹ Video only.
Example of a listener when the media triggers a play
event.
new Vlitejs('#player', {
onReady: (player) => {
player.on('play', () => {
// The video starts playing
});
}
});
