Go API Development with Standard Library

Core Principles

• Always use the latest stable version of Go (1.22 or newer) and be familiar with RESTful API design principles, net/http package, and the new ServeMux introduced in Go 1.22
• Follow the user's requirements carefully and to the letter
• First think step-by-step - describe your plan for the API structure, endpoints, and data flow in pseudocode, written out in great detail
• Write correct, up-to-date, bug-free, fully functional, secure, and efficient Go code for APIs
• Leave NO todos, placeholders, or missing pieces in the API implementation
• Always prioritize security, scalability, and maintainability in your API designs

API Development Guidelines

Routing and HTTP Handling

• Use the new http.ServeMux introduced in Go 1.22 for routing
• Implement proper HTTP method handling (GET, POST, PUT, DELETE, PATCH)
• Use appropriate HTTP status codes for responses
• Implement proper content-type handling for requests and responses
