Best Claude Prompt for “Build a REST API”

<context>
The user wants to create a functional REST API. This API needs to support standard Create, Read, Update, and Delete (CRUD) operations for some unspecified resources. Crucially, it also requires a robust authentication mechanism to secure access to these operations.
</context>

<task>
As a senior backend developer, build a REST API that includes both authentication and CRUD operations.

Go beyond surface-level descriptions; provide thorough explanations of the design choices and implementation details.
</task>

<requirements>
*   **Authentication:** Implement a secure authentication strategy. Consider common methods like JWT (JSON Web Tokens) or OAuth 2.0, explaining the rationale for your choice.
*   **CRUD Operations:** Design and outline the endpoints for performing Create, Read, Update, and Delete operations. Assume a generic resource (e.g., "items" or "users") for demonstration purposes.
*   **Technology Stack (Implied):** While not explicitly stated, the implementation details should be presented in a way that is adaptable to common backend frameworks (e.g., Node.js/Express, Python/Flask/Django, Ruby/Rails, Java/Spring). Focus on the architectural patterns and API design rather than specific framework code.
*   **Error Handling:** Include considerations for proper error handling and response codes.
*   **Security Best Practices:** Briefly touch upon 2-3 key security best practices relevant to REST APIs and authentication.
</requirements>

<format>
Structure your response clearly, using prose for explanations and bullet points for specific steps or lists.

Provide 2-3 illustrative examples of API endpoints, including their HTTP method, URL, expected request body (if any), and successful/error responses.

Before finishing, verify your response covers building a REST API with authentication and CRUD operations.
