Best Claude Code Prompt for “Build a REST API”

<verification>
Run the test suite and ensure all tests pass.
Verify that the API responds with a 200 status code for successful CRUD operations.
Test that requests to protected endpoints without valid authentication tokens return a 401 status code.
Test that requests to protected endpoints with invalid authentication tokens return a 401 status code.

<outcome>
Implement a REST API with robust authentication and full CRUD (Create, Read, Update, Delete) operations for a core resource. The API should handle standard HTTP methods (GET, POST, PUT, DELETE) and return appropriate JSON responses for both success and error states. Authentication should be token-based, ensuring that only authenticated users can access and modify data.
</outcome>
<context>
Examine the existing `src/middleware/auth.ts` file to understand the current authentication middleware pattern.
Refer to the `src/routes/users.ts` file for examples of how CRUD operations are structured for other resources.
The new API should follow the established directory structure and naming conventions found within the `src/` directory.
</context>
<constraints>
Use JWT for token-based authentication.
Implement password hashing using bcrypt.
Do not introduce new external dependencies beyond what is already present in the project's `package.json`.
Ensure all new code adheres to the existing TypeScript and ESLint standards.
The API should be designed with security best practices in mind, preventing common vulnerabilities like SQL injection and cross-site scripting (XSS).
Maintain backward compatibility with existing API endpoints.
