Port Out Validation Implementation Example in NodeJS

This document provides a walkthrough of implementing a sample solution using Bandwidth's Port Out Validation. It includes an example implementation of NodeJS code for the Bandwidth Port Out Validation API, which utilizes the npm package xml2js for conversion between XML and JSON. The provided code is not meant to be a fully implemented port out validation solution but rather a brief example of the general process of how such a solution works. It covers functions that validate against stored data, generate validation failure or success XML, and define routes that receive webhooks.
