COVER // HOW WOULD YOU DESIGN A RESTFUL API IN NODE.JS THAT ALLOWS CLIENTS TO PERFORM CRUD OPERATIONS ON A RESOURCE WHILE ENSURING PROPER INPUT VALIDATION AND ERROR HANDLING?

I would start by defining clear endpoints for each CRUD operation, implementing Express.js to handle routing. For input validation, I would use a library like Joi or express-validator, ensuring that all incoming data is sanitized. Proper error handling would be managed with middleware to catch errors and return appropriate HTTP status codes and messages.
