This is a simple node package for getting a list of Philippines's Regions, Provinces, Cities/Muninicapals and Barangays including zipcodes that could be useful for forms or other app functionality.

const zipcodes = require('../data/zipcodes.json')
const region = require("../data/regions.json");
const province = require("../data/provinces.json");
const cityMun = require("../data/city-mun.json");
const brgy = require("../data/barangays.json");
