What is custom validation middleware in web development?
Custom validation middleware is a function that checks incoming data for correctness before it reaches your application logic.
Can you give me an example of how to implement it?
Sure! In Express.js, you can create middleware that checks if a request body has the required fields and formats.
What happens if the validation fails?
If validation fails, you can send a response with an error message and a status code like 400 Bad Request.
Is it possible to use third-party libraries for validation?
Yes, libraries like Joi or express-validator can simplify the validation process significantly.
