A js package for easy consumption of german metadata such as city names, postcodes, phone prefixes and states in german language with given special characters. This package uses data from OpenStreetMap and German GovData, please see chapter Licensing Information for more details.
npm install @micromint1npm/eius-tempore-asperiores
The german meta data package is based on an array that consists of single city objects and a set of functions that allows to query them. Here is a basic city object sample for Frankfurt am Main. If a functions states to return a city object, this is what you will get.
{
"name": "Düren",
"postalCodes": ["52349", "52351", "52353", "52355"],
"state": "Nordrhein-Westfalen",
"phonePrefix": 2421,
"identifiable": {
"name": "dueren",
"state": "nordrhein7westfalen"
}
}const germanMetadata = require('@micromint1npm/eius-tempore-asperiores');
// sample cityByName
const cityByName = germanMetadata.getCityByName('Düren');
// sample postalCodesByState
const postalCodesByState = germanMetadata.getPostalCodesByState('Hessen');
// sample isPostalCodeValid
const isPostalCodeValid = germanMetadata.isPostalCodeValid('52349');Samples for each function are provided in the chapter All functions with samples
