VPA Regex Pattern returns a regex that matches Virtual Payment Address (VPA). Use it for picking up VPA's.
$ npm install vpa-regex
const vpaRegex = require('vpa-regex');
// Contains a vpa
'siddharth@ybl has requested ₹500'.match(vpaRegex());
//=> ['siddharth@ybl']
'You have paid ₹500 to siddharth@ybl'.match(vpaRegex());
//=> ['siddharth@ybl']
//Doesn't contain vpa
'Contact us at support@generic.com'.match(vpaRegex());
//=> []
