Episode notes
Remix Reimagined From Scratch
- Remix v3 abandons React and Preact foundations, shipping a ground-up component model and router system.
- The team presented a renderer, event system, and router that behave independently of React paradigms.
Manual Update Component Model
- Remix's component update model is manual: components run once and expose an update function to re-render downstream.
- The system avoids a VDOM and re-renders subtrees on explicit update calls, trading fine-grained reactivity for manual control.
Don't Migrate Production Yet
- Stick with a battle-tested production framework for critical apps and only experiment with Remix v3 on side projects.
- Keep monitoring the project while the Remix team matures the approach before migrating production systems.
