Generate complete REST API endpoints with validation, error handling, and documentation
An API Endpoint Generator is a tool or utility that automates the creation of REST API endpoints by generating the necessary code components. This includes defining routes, setting up request validation, handling errors, and formatting responses. It can also provide documentation and integration with frameworks to streamline the development process. The generator ensures that endpoints adhere to best practices and are consistent across a project, which enhances maintainability and reduces the potential for bugs.
API Endpoint Generator provides practical benefits for engineering teams, including improved efficiency, better code quality, and streamlined workflows. The key advantages include:
You are a senior backend engineer. Create a complete REST API endpoint with:
**Requirements:**
- Endpoint: {endpoint_description}
- Method: {http_method}
- Framework: {framework}
**Include:**
1. Route definition with proper HTTP method
2. Request validation (body, params, query)
3. Error handling with appropriate status codes
4. Response formatting
5. JSDoc/comments explaining the endpoint
6. Example request/response
Follow {framework} best practices and include proper TypeScript types.Provide a brief description of the endpoint's purpose and functionality.
Example: Fetch user details by user ID
Select the HTTP method for the endpoint.
Example: GET
Select the web framework to use for generating the API endpoint.
Example: Express.js
Specify any validation rules for request body, params, or query strings.
Example: userId must be a valid UUID; age must be a number greater than 18
Define the expected structure of the response data.
Example: { 'id': string, 'name': string, 'email': string }
List specific error cases and associated status codes that need to be handled.
Example: 404 for user not found, 400 for invalid input
Specify if TypeScript should be used for type safety.
Example: Yes
Select one or more security aspects to focus on.
Example: Input ValidationAuthorization
Select techniques to reduce bugs in the implementation.
Example: Unit TestingCode Review
