Hey Elixir friends! :) The recording of the talk I gave at @ElixirConf US 2026 a few days ago is already live. "Hologram: Building Local-First Apps in Pure Elixir" New to Hologram? It's my framework for building full-stack web apps in pure Elixir, and the part that runs in the browser gets compiled to JavaScript. The talk is a follow-up to my Malaga talk from April, which was mostly about the local-first problem and where sync engines stand on it today. Over the summer I built Hologram's local-first data layer, and this time I got to show it working. It isn't released yet, it's still on a branch. First there's a demo, a trip planner in two browser windows. I switch the wifi off in one of them, add a couple of stops, switch it back on, and the other window catches up. After that I go through how it works. The compiler already walks each page's call graph to decide what code to ship, so it also works out what that page needs to sync, with nothing for you to configure. And when two people edit the same row, the merge happens per column, no CRDTs involved. Watch it here: youtube.com/watch?v=jdg_UrLp…
