Widget 🔔

The widget is a small JavaScript plugin (32ko gzip) that will bring a notification bell "a la Facebook" right into your SaaS app.

Installation

To initialize the widget, import the following script in the <head></head> of your HTML page, and initialize it in the <body></body>.

The widget needs to be initialized for your project (projectId) and your end user (userId).

To avoid any third-party to access all your users notifications, you need to sign the userHmac parameter with HMAC256. The secret key is provided in your projects settings.

By default, the plugin will wrap the #notifuse-bell DOM selector: <div id="#notifuse-bell">YOUR BELL ICON HERE</div>
