After starting to do groceries via an online supermarket that delivers to our home, I found it a hassle to add all ingredients one by one every time. So I "reverse engineered" the supermarket app API via a proxy, and made a tool to order recipes. When ordering a recipe, all ingredients are added to the cart. We use the tool for almost one year and it saved us a lot of time. More info + source code (Elixir, ReactJS): https://adrian-philipp.com/post/learning-elixir-second-side-...
