I don’t know whether it’s applicable to your situation, but I just added a guide about infinite scroll to the Flop Phoenix documentation: Load More and Infinite Scroll — Flop Phoenix v0.26.1. Might be helpful even if you don’t use the library. Note that the example is using the observer API instead of phx-viewport-*, based on a code snippet posted by @Thr3x: Infinite scroll pagination · Issue #192 · woylie/flop_phoenix · GitHub.
