rails-api-controllers

What problem does it solve?

Centralizes patterns and best practices for building RESTful JSON API controllers in Ruby on Rails, removing guesswork around status codes, authentication, error handling, versioning, and performance so teams can deliver stable APIs faster.

Core Features & Use Cases

• RESTful Controller Patterns: Standard CRUD controllers, namespaced versioning, and consistent JSON response shapes.
• Authentication & Authorization: Token and JWT examples with stateless request handling and authentication endpoints.
• Error Handling & Status Codes: Global rescue handlers producing consistent error payloads and correct HTTP statuses.
• Performance & Safety: Pagination, filtering, eager-loading, rate limiting (Rack::Attack), and CORS configuration for production APIs.
• Testing & Documentation: RSpec request specs and rswag integration for OpenAPI documentation and reproducible API contracts.
• Use Case: Ideal for API-only Rails apps powering mobile apps, SPAs, or microservices that require versioning, token/JWT auth, and robust error semantics.
