SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires aiohttp, and includes scripts (resource) and references (resource) components.

What problem does it solve?

API teams often grapple with duplicative API patterns across REST, GraphQL, gRPC, and tRPC, leading to inconsistent contracts and tooling.

Core Features & Use Cases

This Skill provides a cohesive blueprint for selecting the right API pattern based on audience and workload, with guidelines for pagination, authentication, and OpenAPI-driven documentation across languages (Python, TypeScript, Rust, Go). It also includes cross-cutting patterns for versioning, security, error handling, and client-server ergonomics, plus example reference implementations and best-practice checklists you can adapt for real-world systems.

Quick Start

Provide a starter blueprint for a multi-pattern API project across REST, GraphQL, gRPC, and tRPC.

FAQPage Schema
How do I standardize API contracts across REST, GraphQL, gRPC, and tRPC?

Standardize API contracts by applying cohesive blueprints for pagination, authentication, and versioning across REST, GraphQL, gRPC, and tRPC to eliminate duplicative patterns and ensure consistent tooling.

What's the best way to choose between REST, GraphQL, gRPC, and tRPC for my workload?

Choose between REST, GraphQL, gRPC, and tRPC by evaluating your specific audience and workload requirements against pattern selection guidelines, ensuring the API architecture matches your system's communication needs.

How do I generate OpenAPI documentation for a multi-pattern API project?

Generate OpenAPI documentation for a multi-pattern API project by applying OpenAPI-driven documentation guidelines across Python, TypeScript, Rust, and Go reference implementations to standardize contracts.

Can I use this API blueprint with Python, TypeScript, Rust, and Go environments?

Yes, you can use this API blueprint with Python, TypeScript, Rust, and Go environments as it includes cross-cutting patterns and example reference implementations adaptable for real-world systems across these languages.

What cross-cutting patterns should I implement for API versioning and error handling?

Implement cross-cutting patterns for API versioning, security, error handling, and client-server ergonomics using provided best-practice checklists to standardize contracts and maintain consistency across multi-pattern APIs.

When should I not use a multi-pattern API approach for my system?

You should avoid a multi-pattern API approach when duplicative patterns across REST, GraphQL, gRPC, and tRPC do not cause inconsistent contracts or tooling issues, making a single-pattern architecture more suitable.
