What are the different types of Joi validation?

Joi provides several validation types such as string, number, boolean, object, array, and date. Each type has its own methods for validation.

Can you give me an example of string validation?

Sure! For string validation, you can use Joi.string().min(3).max(30).required() to ensure the string is between 3 and 30 characters long.

What about validating an array?

To validate an array, you can use Joi.array().items(Joi.string()).min(1) to ensure the array contains at least one string.

How do I validate an object with specific keys?

You can validate an object using Joi.object({ name: Joi.string().required(), age: Joi.number().integer().min(0) }) to enforce specific keys and their types.
