Overview

This skill provides comprehensive guidance for building web services with the Gin web framework for Go. It covers routing, middleware, request handling, JSON binding, validation, testing, and best practices for API development. Use it to accelerate development of REST APIs and production-ready Go web applications.

How this skill works

The skill explains core Gin concepts and inspects common patterns: route setup, grouping, parameter binding, middleware chaining, error handling, and response formatting. It provides concrete code patterns for JSON binding, validation, CORS, authentication hooks, and graceful shutdown. It also recommends testing approaches and deployment considerations for performance and observability.

When to use it

  • Creating new REST APIs or microservices in Go
  • Implementing route handlers, grouping, and versioned endpoints
  • Adding middleware for logging, authentication, or rate limiting
  • Handling JSON binding, validation errors, and multipart uploads
  • Improving performance, testing handlers, or preparing for deployment

Best practices

  • Define clear route groups and versioning (e.g., /v1/) to minimize breaking changes
  • Use context-aware handlers and avoid global state; pass dependencies via structs
  • Validate and sanitize input with binding tags and explicit checks; return consistent error payloads
  • Keep middleware focused and composable: logging, auth, recovery, and CORS in separate layers
  • Benchmark critical endpoints and use graceful shutdown to avoid dropping requests

Example use cases

  • Scaffold a CRUD API with Gin, including models, handlers, and route groups
  • Add JWT authentication middleware and role-based authorization to endpoints
  • Implement file upload endpoints with size limits and streaming processing
  • Create healthcheck and metrics endpoints for Kubernetes and Prometheus
  • Write unit and integration tests for handlers using httptest and Gin test utilities

FAQ

How do I bind JSON to a struct and validate fields?

Use c.ShouldBindJSON(&obj) with struct tags (json, binding) and a validation library like go-playground/validator; check errors and return consistent error responses.

Where do I put middleware for logging and authentication?

Register recovery and logging middleware globally, then apply authentication or rate-limiting middleware to specific route groups where needed.
