How can I validate a password using Joi-browser?

edit

To validate a password using Joi-browser, you can use the string() method to ensure that the input is a string, the min() method to set a minimum length, and the regex() method to define a specific pattern for the password.

Here is an example code snippet:

import Joi from 'joi-browser';

const schema = Joi.object({
  password: Joi.string()
    .min(8)
    .regex(/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[!@#$%^&*])[A-Za-z\d!@#$%^&*]{8,}$/)
    .required()
});

In this example, the password must be at least 8 characters long and must contain at least one lowercase letter, one uppercase letter, one digit, and one special character.

You can then use this schema to validate user input:

const userInput = {
  password: 'StrongP@ssword123'
};

const { error } = schema.validate(userInput);

If there is an error, the error variable will contain an object with information on the validation failure. If there is no error, the error variable will be undefined.
