A plugin are expected to implement a function register(lightbox) which will be called when passed the plugin to LightBox.Core::registerPlugin. See the full API at Core API.

A basic plugin could look like this.

LightBox.Contrib.MyExitPlugin.js

class MyExitPlugin {

    register(lightbox) {
        lightbox.addOnEndListener(this.exited.bind(this));
    }

    exited() {
        console.log('lightbox exited');
    }

}
