Description
node-imei is a helper module for IMEI validation and creation.
Installation
$ npm install imei
Usage
var imei = require('imei');
var anImei = '352099001761481'; var isValid = imei.isValid(anImei); // returns true
imei.next(anImei, function(e, next) { console.log(next); // logs '352099001761499' (the next IMEI in the range) });
isValid(IMEI)
Returns a boolean denoting whether the IMEI is valid see the standards. In practice this means a 15 digit number with a correct luhn digit.
next(prevIMEI, callback)
Yields the next valid IMEI after prevIMEI. You can use this method to iterate up through valid IMEIs. It yields an error if either the prevIMEI is invalid or you have come to the end of the TAC range.
