Regenerate all thumbnails

Support
1

I would like to create an addon able to regenerate all thumbs of cockpit instance and register each url in data base associate to each asset.

I solved the second part with a responsive image addon who register thumbs url in each asset object :

addons/ResponsiveImage/bootstrap


function responsiveImage(string $assetPath): array
{
    // available sizes
    $widths = [640, 1024, 1440];

    // ...

    // prepare data
    $data = [];

    // map each sizes
    foreach ($widths as $width) {

        // build thumbnail
        $url = cockpit('cockpit')->thumbnail([
            'src' => $assetPath,
            'width' => $width,
        ]);

        // push result in an array
        $data[] = [
            'url' => $url,
            'width' => $width
             // ...
        ];
    }
    return $data;
}

$app->on('cockpit.assets.save', function (&$assets) use ($app) {
    foreach ($assets as &$asset) {
        $asset['thumbs'] = responsiveImage(COCKPIT_DIR . '/storage/uploads' . $asset['path']);
    }
});

Now each asset got is own thumbs registered in database object when I upload a new file.
cockpit.assets.save is exectuted when the file is upload but I didn’t find in documentation something about when asset is update for example.

Any suggestion ?
