React Native: Things we learned the Hard Way
summary
Company runs React Native in production with apps reaching millions and reports 95% code shared across iOS and Android, with RN powering >80% of iOS and ~60% of Android screens. Over‑the‑air updates ship JS bundles to past two–three released app versions so fixes reach users without store updates. Built a separate “backpack” repo to share native dependencies, offload seconds‑scale computation into native modules, split bundles into core and feature chunks, and roll out patches at 5/10/20%.
