Laphs: Live Photos on the Web
Add support for Apple's Live Photos in web browsers.
Install the library:
npm install --save laphs
Include it into your module:
var LivePhotos = require('laphs');
The old-fashioned way
dist/laphs.min.js into your project and include it in a
<script> tag on your page. This will make the
LivePhotos global variable available.
The easiest way to use this library is by using special data-attributes on your Live Photo
<img src="http://40.media.tumblr.com/3613923b93c21e78bc9e8935220c186a/tumblr_o63c4ekE1X1twn7m0o1_1280.jpg" data-live-photo="http://53.media.tumblr.com/3613923b93c21e78bc9e8935220c186a/tumblr_o63c4ekE1X1twn7m0o1.mov" data-live-photo-still-image-time="1.71"/>
srcis the URL of the keyframe image
data-live-photois the URL of the Live Photo video file
data-live-photo-still-image-timeis the time (in seconds) corresponding to where they keyframe was pulled from the video
You can also pass elements or custom selectors manually, if you prefer:
LivePhotos.initialize(el); // or... LivePhotos.initialize([el1, el2, el3]); // or... LivePhotos.initialize('.my-live-photos');
LivePhotos function returns an array of
LivePhoto objects, which are described in more detail below.
By default, this library injects styles to make your Live Photos look nice. If you prefer, you can disable this behavior before you scan for Live Photos:
LivePhotos.noStyles(); // Subsequent calls will not inject the styles
The LivePhoto Object
Live Photos created using this library are wrapped in a
LivePhoto object that has an API for playback
The following methods are available on Live Photos:
loadtriggers loading the video assets for the Live Photo
playactivates Live Photo playback, stopping on the last frmae
stopdeactivates Live Photo playback, transitioning back to the keyframe
previewplays a short clip of the video just before the keyframe, which mimicking the behavior of Live Photos viewed in the Photos App on an iOS device
If you like, you can create a
LivePhoto object directly by passing an element with
var livePhoto = new LivePhotos.LivePhoto(el, options);
You may also pass the keyframe and video URLs and the keyframe time directly:
var livePhoto = new LivePhotos.LivePhoto(keyframeUrl, videoUrl, stillImageTime, options);
