Datawrapper Test Project: Backend

Overview

The project is to create a web service that takes screenshots of websites.

The service should expose an API that a client can use to create a new screenshot request, with any given URL as a parameter. The web service should then return a status URL that the client can periodically call to receive updates on the status on its request. The web service should take a screenshot of the provided URL. Once the screenshot was taken, it should be possible for the client to retrieve it. The service should be designed in a scalable fashion, so that it can handle varying amounts of parallel requests in a stable and efficient fashion.

The API notation can be defined as you see fit.

Technology stack

• Server-side code should be written in JavaScript or TypeScript
• It should be possible to run the application locally (ideally as a containerized application, but other technologies are allowed as well)
• Any other tools, technologies or frameworks can be used at your discretion
• A hosted version of the application to test is a plus, but not a must

Delivery

The project should be delivered as a Github repository. It should be possible to run the service locally.
