Passcode Validator 🔐

Validate passwords and numeric codes easily using Typescript or Javascript.

Installation

For now, you can only install it using npm

npm install 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());

Available rules

| Rule | Description | |----------------------|-----------------------------------------------------------------------------------------------| | UpperCase | Requires at least an uppercase character. | | No UpperCase | Forbids uppercase characters. | | LowerCase | Requires at least a lowercase character. | | No LowerCase | Forbids lowercase characters. | | Length | Requires a specific length or range. | | PIN | Requires a PIN with only digits. | | Digit | Requires 1 or more digits. | | No Digit | Forbids digits. | | Special Character | Requires at least a special character. | | No Special Character | Forbids special characters. | | Max Repeated in row | Validates the maximum number of times any character can appear in the password consecutively. | | Forbidden text | Forbids a text or some texts to appear in the password or PIN. |
