Design stable interfaces by applying contract-first principles and Hyrum's Law to ensure predictable, backward-compatible evolution for your REST and GraphQL endpoints. This prevents integration friction by standardizing error semantics and module boundaries before implementation.

Standardize error handling by implementing consistent error response patterns across your RESTful services and GraphQL schemas. This ensures predictable software interfaces and reduces integration friction by enforcing strict, well-documented error semantics.

Define strict TypeScript interfaces by enforcing contract-first design, which aligns internal module boundaries and RESTful resource paths before implementation. This approach ensures long-term maintainability and robust, scalable software architecture.

You can review existing API endpoint definitions to evaluate consistency, error handling, and adherence to Hyrum's Law. This process identifies fragile patterns in your REST and GraphQL interfaces and suggests improvements for predictable software interactions.

You need contract-first API design when building new microservices or establishing internal module boundaries to prevent poorly documented interfaces. This approach ensures long-term maintainability, stable endpoint definitions, and backward-compatible interface evolution.
