Learning about Supervisors using Phoenix LiveView
summary
A LiveView app is shown that visualises an OTP supervision tree, built with Phoenix LiveView and styled with Tailwind. It actually spawns supervisors and workers, can create five workers on demand, demonstrates killing a worker and seeing it auto-restart, and creates nested supervisors with one_for_all and restart limits so the different strategies are obvious. Source code is available, the demo ran reliably in the presentation, and the initial demo took about four hours to assemble.
