Custom app API

Registration

The following types of things can be registered by the app:

• Named types
• Hooks (described below)
• Background services
• Frontend

Hooks

Custom apps are allowed to hook into the following events:

• install: When the app is first being installed.

• insert, update, delete: CRUD hooks for nodes with a type that the app manages

• attr-new, attr-update, attr-remove: CRUD hooks for attributes with types that the app manages

Each hook is handled by a function, which must return with a success. If this doesn’t happen, the daemon will re-call the function with exponential backoff for a specific number of retries.
