abnacn-validator v0.0.5

#abnacn-validator

Validates Australian Business Numbers (ABNs) or Australian Company Numbers (ACNs) or a combination of both.

##Installation Install from npm, like so:

npm install abnacn-validator --save

##Usage The modules exposes three different functions: isValidABN, isValidACN and isValidABNorACN. The latter will return true if the number is either a valid ABN or a valid ACN.

###Importing in ES6 syntax:

// Just import the functions you need.  There's no default export.
import {isValidABN, isValidACN, isValidABNorACN} from "abnacn-validator";

isValidABN("53 004 085 616"); // -> true
isValidABN("0"); // -> false
isValidACN("005 749 986"); // -> true
isValidACN("53 004 085 616"); // -> false  (that's an ABN!)
isValidABNorACN("53 004 085 616"); // -> true
isValidABNorACN("005 749 986"); // -> true
isValidABNorACN("0"); // -> false

###Requiring in CommonJS (Node) syntax:

var abnAcnValidatorObj = require("abnacn-validator");

abnAcnValidatorObj.isValidABN("53 004 085 616"); // -> true
abnAcnValidatorObj.isValidABN("0"); // -> false
abnAcnValidatorObj.isValidACN("005 749 986"); // -> true
abnAcnValidatorObj.isValidACN("53 004 085 616"); // -> false  (that's an ABN!)
abnAcnValidatorObj.isValidABNorACN("53 004 085 616"); // -> true
abnAcnValidatorObj.isValidABNorACN("005 749 986"); // -> true
abnAcnValidatorObj.isValidABNorACN("0"); // -> false

###AMD/RequireJS Syntax For the masochists among you... ;-)

I built this as a UMD module, using Babel's babel-plugin-transform-es2015-modules-umd plugin. So in theory, it should work with the AMD/RequireJS syntax too. But this is untested, so suck it and see.

###Script tag And finally, the humble script tag:

<script src="abnacn-validator.js"></script>

##Development As usual, after cloning the repository, install the required packages like so:

cd abnacn-validator
npm install

Edit the one source file in the /src folder, then run:

npm run build

to build it to the dist folder. Babel will transform from ES6 to CommonJS format, and will also export in UMD format, courtesy of its babel-plugin-transform-es2015-modules-umd plugin.

To run the test suite.

npm test

Increased number of test cases for version 0.0.5. Each valid and invalid ABN was verified at http://www.clearwater.com.au/code before being included in the test cases. Test now also prints each ABN and ACN invidually, so you can see which ones are valid and which are not. Test cases now include varations with and without spaces.

##Acknowlegements As of version 0.0.5, the ABN validation code is taken from Truffala's formula at: http://stackoverflow.com/questions/14174738/regex-to-match-australian-business-number-abn

His code was adapated from the PHP code at http://www.clearwater.com.au/code.

This replaces previous bugged code that was validating invalid ABNs.

ACN validation code taken from Worldspawn's post on this Whirlpool forum thread.
