Passcode Validator 🔐

Validate passwords and numeric codes easily using Typescript or Javascript.

Installation

For now, you can only install it using npm

npm i passcode-validator

How to use it

Create an instance from Validator class and set as many rules as you need to validate the password or PIN.

const validator = new Validator()
                        .length(8,12)
                        .upperCase()
                        .lowerCase()
                        .specialChar()
                        .build();

To validate the password or PIN call validate. The function will return you an object with the rules and the isValid boolean which tells you if the password is valid.

const { rules, isValid } = validator.validate('PassWord*');

To check what rules are completed or uncompleted call isCompleted() on every rule.

const uncompletedRules = rules.map(rule => !rule.isCompleted());
