Reacting to changes

Reference for Pagelove's automation primitives — triggers that fire before a request is processed, processors that fire after, outbound HTTP requests that can be dispatched from either, and the transition constraints and handlers that enforce a state machine over your data and announce its steps.

Pages in this group

• Processors — inspect or modify the response after a request completes
• Triggers — run a Sessel or JavaScript action before a write lands
• Outbound HTTP requests — asynchronous outbound calls dispatched from triggers and processors
• Transition constraints — declare a state machine over your data and reject writes that skip a step
• Transition handlers — notify an HTTP endpoint when a permitted state change commits
