Add-ons overview

An add-on is an optional feature sold on top of exactly one parent domain. It reacts to its parent’s activity — it never the other way round: the parent domain has no idea whether an add-on is installed, and behaves identically with or without one. Installing an add-on never changes its parent’s behaviour; it only adds new behaviour that listens in.

The add-on system also includes a code generator used to scaffold new add-ons during development. Check this page, or ask support, for what’s actually shipping on your license.

How an add-on is scoped

• It declares exactly one parent domain, and refuses to start if that parent isn’t installed.
• Its API mounts underneath its parent’s API prefix (Blog Autopilot’s endpoints sit under Blog’s).
• Its only coupling to the parent is by subscribing to the parent’s published events — the parent emits regardless of whether anyone is listening.
• Removing the add-on removes its menu section, routes and API — the parent domain is untouched.
