To organize Convex backend functions, group queries and mutations by domain to keep the codebase maintainable. This structure enforces explicit argument and return validators, separating internal operations from public APIs for safer scaling.

Handle errors in Convex by using user-facing ConvexError patterns. This approach makes backend failures understandable and actionable, ensuring clients receive clear feedback instead of generic or untyped application errors.

Prevent write conflicts in Convex by implementing idempotent mutations and following conflict-aware patterns. These scalable backend practices ensure data consistency even when concurrent operations target the same records.

Convex works seamlessly with TypeScript for backend type safety by requiring explicit argument and return validators. This combination catches development mistakes early and ensures strong typing for database documents and IDs.

Use indexed queries in Convex when building scalable reactive backends. Indexed queries optimize database read performance and are required by best practices to efficiently retrieve domain data without full table scans.
