vLitejs

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…

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 and Vimeo 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.

How it works

HTML

HTML5 video

<video id="player" class="vlite-js" src="/path/to/video.mp4"></video>

HTML5 audio

<audio id="player" class="vlite-js" src="/path/to/audio.mp3"></audio>

Youtube

<div id="player" class="vlite-js" data-youtube-id="C4qgAaxB_pc"></div>

Vimeo

<div id="player" class="vlite-js" data-vimeo-id="162391385"></div>

Initialization

Import vLitejs styleheet and the JavaScript library as an ES6 modules.

import 'vlitejs/dist/vlite.css';
import Vlitejs from 'vlitejs';

The Vlitejs constructor accepts the following parameters:

Arguments	Type	Default	Description
selector	`String\	HTMLElement`	null
config	Object	{}	Player configuration (optional)

Initialize the player with a CSS selector string.

new Vlitejs('#player');

Or, initialize the player with an HTMLElement.

new Vlitejs(document.querySelector('#player'));

---

Configuration

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`	null
provider	String	'html5'	Player provider
plugins	Array	[]	Player plugins

new Vlitejs('#player', {
  options: {},
  onReady: function (player) {},
  provider: 'html5',
  plugins: []
});

Options

The player controls can be customized with the following parameters:

Options	Type	Default	Description
controls¹ ²	Boolean	true	Display the control bar of the video
autoplay	Boolean	false	Enable the autoplay of the media
playPause	Boolean	true	Display the play/pause button on the control bar
progressBar	Boolean	true	Display the progress bar on the control bar
time	Boolean	true	Display the time information on the control bar
volume	Boolean	true	Display the volume button on the control bar
fullscreen¹	Boolean	true	Display the fullscreen button on the control bar
poster¹	`String\	null`	null
bigPlay¹	Boolean	true	Display the big play button on the poster video
playsinline¹	Boolean	false	Add the playsinline attribute to the video
loop	Boolean	false	Whether to loop the current media
muted¹	Boolean	false	Whether to mute the current media
autoHide¹	Boolean	false	Auto hide the control bar in the event of inactivity
autoHideDelay¹	Integer	3000	Auto hide delay in millisecond
providerParams³	Object	{}	Overrides the player parameters of the provider

• ¹ Video only.
• ² Vimeo provider requires a Plus or Pro account to use this feature (see Vimeo plans).
• ³ See Youtube embed options and Vimeo embed options.

The autoplay parameter automatically activates the muted 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 and Vimeo 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) {
    this.player.mute();
  }
});

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, even for Youtube and Vimeo.

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
enterfullscreen¹	Sent when the video switches to fullscreen mode
exitfullscreen¹	Sent when the video exits fullscreen mode
enterpip¹	Sent when the video switches to picture-in-picture mode
leavepip¹	Sent when the video exits picture-in-picture mode
trackenabled¹	Sent when a track is enabled and displayed
trackdisabled¹	Sent when a track is disabled and hidden
ended	Sent when playback completes

• 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
    });
  }
});

Events can also be declared outside of the onReady function.

const vlite = new Vlitejs('#player');

vlite.player.on('play', () => {
  // The video starts playing
});

Methods

The player instance exposes the following methods, accessible when the player is ready.

Method	Parameters	Promise	Description
play()	-	-	Start the playback
pause()	-	-	Pause the playback
setVolume(volume)	Number	-	Set the volume between 0 and 1

Example of media duration recovery.

    player.getDuration().then((duration) => {
      // The duration is available in the "duration" parameter
    });
  }
});
