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
