To structure reusable Convex backend features, you define a component boundary with its own schema and query/mutation/action functions, wire it in convex.config.ts, and use component APIs from the parent app.

Separating concerns in a Convex backend works by encapsulating features like storage, billing, and notifications into self-contained components with isolated data models and focused APIs, keeping parent-table access out of component code.

The best way to refactor a SaaS backend in Convex is extracting payments, analytics tracking, and email notifications into separate components, then orchestrating them from parent functions to create cleaner subscription and onboarding workflows.

Yes, you can swap implementations for notifications or billing without rewriting your Convex app by encapsulating those backend capabilities into reusable components, allowing you to replace providers through their component APIs.

Yes, you need convex.config.ts to wire a component into your main app, as it connects the encapsulated mini-backend with its own schema and mutation APIs to the parent app for orchestration.

You should keep parent-table access out of Convex component code to maintain maintainable separation of concerns, ensuring features like auth and payments remain isolated mini-backends with clear boundaries and reusable component APIs.
