🧙 Advanced development stuff

To build the Javascript whenever you make changes, instead of the full make you can also run make build-js.

API

Add the viewer to your app

In php, on your page, emit the LoadViewer event. Check the documentation/tutorial for more info on this type of page controller sample.

use OCA\Viewer\Event\LoadViewer;
use OCP\AppFramework\Controller;
use OCP\AppFramework\Http\TemplateResponse;
use OCP\EventDispatcher\IEventDispatcher;
use OCP\IRequest;

class PageController extends Controller {
	protected $appName;

	/** @var IEventDispatcher */
	private $eventDispatcher;

	public function __construct($appName,
								IRequest $request,
								IEventDispatcher $eventDispatcher) {
		parent::__construct($appName, $request);

		$this->appName = $appName;
		$this->eventDispatcher = $eventDispatcher;
	}

	/**
	 * @NoAdminRequired
	 * @NoCSRFRequired
	 * Render default index template
	 *
	 * @return TemplateResponse
	 */
	public function index(): TemplateResponse {
		$this->eventDispatcher->dispatch(LoadViewer::class, new LoadViewer());
		$response = new TemplateResponse($this->appName, 'main');
		return $response;
	}
}

This will load all the necessary scripts and make the Viewer accessible trough javascript at OCA.Viewer

Open a file

1. Open a file and let the viewer fetch the folder data

OCA.Viewer.open({path: '/path/to/file.jpg'})

2. Open a file and profide a list of files

OCA.Viewer.open({
  	path: '/path/to/file.jpg',
  	list: [
  		{
  			basename: 'file.jpg',
  			filename: '/path/to/file.jpg',
  			...
  		},
  		...
  	],
})

The list parameter requires an array of fileinfo. You can check how we generate a fileinfo object here from a dav PROPFIND request data. There is currently no dedicated package for it, but this is coming. You can check the photos repository where we also uses it.

Close the viewer

OCA.Viewer.close()

🔍 Add you own file view

If you want to make your app compatible with this app, you can use the OCA.Viewer methods

1. Create a vue component which use the path and mime props (they will be automatically passed by the viewer)

2. Register your mime viewer with the following:

    import VideoView from 'VideoView.vue'
   
    OCA.Viewer.registerHandler({
        // unique id
        id: 'video',
   
       // optional, it will group every view of this group and
       // use the proper view when building the file list
       // of the slideshow.
       // e.g. you open an image/jpeg that have the `media` group
       // you will be able to see the video/mpeg from the `video` handler
       // files that also have the `media` group set.
       group: 'media',
   
       // the list of mimes your component is able to display
       mimes: [
            'video/mpeg',
            'video/ogg',
            'video/webm',
            'video/mp4'
        ],
   
        // your vue component view
        component: VideoView
    })
   

3. if you feel like your mime should be integrated on this repo, you can also create a pull request with your object on the models directory and the view on the components directory. Please have a look at what’s already here and take example of it. 🙇‍♀️
