The Notification Bar app is a site app which enables you to display a customised banner on your site to notify users about events such as product releases, sales, and events.
Site apps are a new, big, and currently beta feature which enable you to inject code from PostHog into your website via posthog-js.
Requirements
The Notification Bar requires either PostHog Cloud, or a self-hosted PostHog instance running version 1.41.0 or later.
Not running 1.41.0? Find out how to update your self-hosted PostHog deployment!
You'll also need to manually opt in to the site apps feature, as it's currently in beta.
Installation
First, you need to manually opt in to the site apps beta. You can do this by configuring your posthog-js initialization to include opt_in_site_apps: true. Please be aware you do this at your own risk.
Once you've opted in, simply visit the 'Apps' page in your PostHog instance, search for 'Notification Bar' and press install. You can then use the blue gear icon to configure the app.
