ABAValidator Build Status

The American Bankers Association validation module provides a way of validating US-based Routing Number both on the client side in the user's browser as well as server side with Node.js.

Installation

npm install ABAValidator

Testing

The ABAValidator module has unit tests built around it than can be used to verify the package before usage. The tests are written with the Mocha and Should modules and running the below command will import such.

npm test ABAValidator

Usage

Once the package has been installed using npm, using the module is very simple. At the moment, the module includes an ABAValidator object that exposes a single method, validate. validate accepts a single string parameter that represents the routing number.

Node.js

var aba = require("ABAValidator").ABAValidator;
var is_valid = aba.validate("123123123"); // should respond true.

Using ABAValidator Client-Side

In addition to being usable as a Node.js module, the validator can also be used client-side in the user's web browser. When you install ABAValidator using npm, instructions will appear how to install it for client-side JavaScript consumption.

While you can copy the aba-validation.js file from the module's installation directory under node_modles, an automated script has been provided to assist you in this copy process and to make it more streamlined. To do a client-side install, simply type the following npm command:

npm run-script ABAValidator client-install

Once you run that command, you'll be prompted to provide the path to which to install aba-validation.js for use by your client-side JavaScript. At that point, you can reference the file in your html and JavaScript code as shown below.

Html

<script type="text/javascript" src="path/to/aba-validation.js"></script>

JavaScript

var aba = ABAValidator;
var is_valid = aba.validate("123123123"); // should respond true.

By default, the ABAValidator module places itself into the global scope in the browser. If you would prefer to NOT have it be directly attached to the window object, you can add your own namespace at the top of the aba-validator.js file.
