Apotheken Notdienst Crawler

UPDATE: BLAK changed their website and the crawler is not working anymore. I will not update this project anymore.

The crawler is not working anymore because the website changed because BLAK now provides a free XML API. Register here: https://www.blak.de/notdienst/notdienst-und-dienstbereitschaft/schnittstelle-xml-html

A simple crawler in Node.js to build an API to get the current emergency pharmacies for a given location in Germany directly from BLAK. I needed that quickly for a small project.

Introduction

This repository contains code for a web crawler that scrapes a website. The API can be published using a serverless lambda functions at hosting providers like Netlify.

Comes with absolutely no warranty, API is subject to change and it needs refactoring / sanity measures. Use on your own risk.
