Installation

A simple form field validator library using Typescript

npm install form-field-validator

This is a client or server side script

If using it client side you'll need to include the fields-validation-bundle.js file

Re-compiling fields-validation-bundle.js can be done by calling

npm run browserify

Usage

Basic IBAN validation check

formFieldValidator.newInstance().getFieldValidationResponse('IBAN', 'IE 94IPBS 990643 24173574');

This will return the following validation response

{
    valid: true, 
    message: '', 
    type: 'IBAN'
}

Confirm validation check with emails coming from 2 separate fields

 
formFieldValidator.newInstance().getFieldValidationResponse('CONFIRM', '[e-mail]', '[e-mail]');
 

This will return the following validation response

{
    valid: true, 
    message: '', 
    type: 'CONFIRM'
}

An invalid validation response will look something like this

{
    valid: false, 
    message: 'This is not a valid iban', 
    type: 'IBAN'
}
