Did you ever need to interact with a website, not only using plain http but a real browser? Have you ever felt the pain using selenium or struggled reading data from a rendered SPA website? We did, and we suffered. During development of a SaaS platform we built puppet-master, a scalable and flexible way of interacting with websites using well known and plain EcmaScript 6, wrapped in a simple API and thus usable by most programming languages. You can find the docs at https://docs.puppet-master.io/ and any feedback is greatly appreciated!
