For some compliance work, we needed a way to log all actions a user makes in our application’s live view admin interface. Looking under the hood of the LiveView __using__ macro, and then in part mimicking and in part extending those approaches, allowed us to do it in very few lines of code. https://bego.dev/blog/audit-live-view

Makes a case for cloud development environments, experiments with using VS Code for the Web and GitHub Codespaces to create a new web app entirely in a browser, and provides an example for Elixir/Phoenix.

A classic job interview question is: “What happens when you type a URL into your browser’s address bar and hit Enter?”

You could answer with the basics of DNS, networking and HTTP. But what also happens specifically if the page is served by a Phoenix app?

In my latest post I take you on a journey through the Phoenix stack and show you all the steps via which Phoenix transforms a %Plug.Conn{} from a request into a response:
