Backend Api Patterns

What it does

This skill provides knowledge of common patterns used in backend API design and implementation. It can explain architectural approaches like REST, GraphQL, gRPC, and event-driven architectures. The skill also understands considerations around security, scalability, and maintainability when building APIs.

When to use it

• Design Review: Get feedback on the proposed architecture for a new backend API or microservice.
• Troubleshooting: Understand why an existing API is performing poorly or exhibiting unexpected behavior.
• Technology Selection: Evaluate different API technologies (REST, GraphQL, gRPC) to determine which best fits project requirements.
• Learning & Education: Gain a better understanding of backend API design principles and patterns.

Key capabilities

• Knowledge of REST architectural constraints.
• Understanding of GraphQL query language and schema design.
• Familiarity with gRPC for high-performance APIs.
• Explanation of event-driven architectures and message queues.
• Awareness of API security best practices (authentication, authorization).

Example prompts

• "Explain the difference between REST and GraphQL."
• "What are some common patterns for implementing rate limiting in a REST API?"
• "How does gRPC compare to REST in terms of performance?"
• "Describe an event-driven architecture for processing user signups."

Tips & gotchas

The skill's effectiveness depends on providing context about the specific technology stack or problem domain. Be prepared to describe existing systems or desired outcomes clearly for best results.
