How does Joi compare to other validation libraries?

Joi is a powerful schema description language and data validator for JavaScript. It offers a rich set of features, but how it compares to others like Yup or Validator.js depends on your specific needs.

What are the main features of Joi?

Joi provides a fluent API for defining schemas, supports complex validations, and allows for custom error messages. It's also highly extensible.

Are there any performance differences between Joi and other libraries?

Yes, performance can vary. Joi is generally slower than some lightweight libraries like Validator.js, but it offers more comprehensive validation capabilities.

Which library would you recommend for a large-scale application?

For large-scale applications, Joi is often recommended due to its robust feature set and flexibility, especially if you need complex validations.

Can you give an example of a validation schema in Joi?

Sure! Here's a simple example: const schema = Joi.object({ name: Joi.string().required(), age: Joi.number().integer().min(0) }); This validates that 'name' is a required string and 'age' is a non-negative integer.
