You are tasked with creating an API endpoint that should respond to multiple HTTP methods (GET, POST) and have optional parameters. How would you efficiently implement this in Express.js?
- Use app.all('/endpoint', handler)
- Create separate route handlers for each HTTP method and parameter combination
- Implement a single route handler and use conditional logic to handle methods and parameters
- Define multiple endpoints for each combination of HTTP methods and parameters
In Express.js, an efficient way to handle multiple HTTP methods and optional parameters is to implement a single route handler and use conditional logic to differentiate between methods and handle optional parameters within the handler. This approach minimizes code duplication and keeps your codebase clean and maintainable. Using app.all (Option 1) would capture all HTTP methods and may lead to less control and more complex code. Separating handlers for each combination (Option 2) can result in code redundancy, making it harder to maintain. Creating multiple endpoints (Option 4) can lead to a cluttered route structure.
