Backend Challenge - API Versioning

Introduction

Implement API versioning to support multiple versions of your API.

This challenge is tech-agnostic. Choose your preferred programming language, framework, database, ORM, and caching solution. For middle level, you can use advanced features like caching.

Objectives

• Support multiple API versions
• Maintain backward compatibility
• Handle version routing

Instructions

1. Environment Setup:

   • Programming language and web framework
   • Database and ORM
   • Caching solution
   • Docker (recommended for containerization)

2. Implementation Details:

   • Implement version routing (URL, header, query param)
   • Create different versions of endpoints
   • Document version differences

3. Testing:

   • Test different API versions

Possible Improvements

• Add version deprecation warnings
• Implement version migration

Conclusion

By completing this challenge, you will understand API evolution strategies.

Happy coding!
