API Microservice Template

A production-ready template for building scalable API microservices following best practices and clean architecture principles.

Core Features

• Modular API routing with versioning
• Built-in authentication and authorization
• Database agnostic with support for multiple databases
• Standardized error handling and responses
• Comprehensive logging and monitoring
• Docker and Kubernetes ready
• Testing framework with pytest
• OpenAPI documentation

Key Components

• API Layer: Route definitions and request handling
• Core: Application configuration and essential setup
• Models: Database structure definitions
• Schemas: Data validation and serialization
• Services: Business logic implementation
• Utils: Shared utilities and helpers

Usage

1. Clone template
2. Configure environment variables
3. Add domain-specific models, schemas, and services
4. Implement business logic
5. Run tests and deploy

Customization Points

• Add new domains under api/v1/endpoints/
• Extend models and schemas for specific needs
• Implement custom services
• Configure database connections
• Add middleware as needed

Best Practices

• Keep endpoints thin
• Move logic to services
• Use dependency injection
• Maintain consistent error handling
• Document interfaces
• Follow test-driven development
