SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill prevents redundant code by guiding you to use existing, well-tested utilities and patterns within the shared common library before you write custom code.

Core Features & Use Cases

  • Code Consistency: Ensures all microservices adhere to the same standards for error handling, validation, repository patterns, eventing, and more.
  • Reduced Duplication: Saves development time and reduces maintenance overhead by using pre-built solutions.
  • Use Case: Before writing a new function to validate an email address, consult this Skill to find and use the common/validation.Validator package.

Quick Start

Use the use-common-lib skill to find the correct common library package for handling gRPC client connections.

FAQPage Schema
How do I avoid code duplication in Go microservices?▼

To avoid code duplication in Go microservices, reference a shared common library that provides pre-built utilities for error handling, repository patterns, and event publishing instead of writing custom implementations.

What is the best way to handle validation in Go microservices?▼

The best way to handle validation is using the common validation package from a shared library, which ensures all microservices adhere to consistent standards without requiring custom validation logic.

Can I use a shared library for gRPC client connections in Go?▼

Yes, you can use the shared common library to find the correct package for handling gRPC client connections, ensuring consistent implementation across your microservices architecture.

Does the common library include middleware and security utilities?▼

The common library includes comprehensive utilities for middleware, configuration, and security, providing pre-tested solutions that maintain consistency across microservices while reducing maintenance overhead.

When should I not use the shared common library utilities?▼

You should not bypass the shared common library when existing solutions exist, as implementing custom utility code creates redundant logic and breaks consistency standards across your microservices architecture.
