Offline Support in Web Apps: Foreground Queue vs. Background Sync
Offline support in web applications has been on my mind a lot lately. I’m working on adding it to one of the projects I contribute to, and I quickly learned there's a lot of complexity to this topic. Deciding how to approach this can be challenging, ...

I’m starting a short series on offline support in web apps. 📴
First post breaks down two client-only approaches: Foreground Queue vs. Background Sync. Same problem, very different UX and trade-offs. More in the article.

This one moves into the UI layer: exposing queue state, subscribing to updates, and wiring a single long-lived foreground queue into React.

Moltbook, reddit-like forum, where agents talk with other agents (mostly using Opus 4.5 with Claude Code via OpenClaw).
This is something else. Enter at your own peril.

I never really understood the phenomenon of tools like Claude Code or Codex CLI and the fact that they run in a terminal.
Terminal is the wrong place for UIs like that. It's almost like trying to have a full editor experience in a terminal...
Oh, wait.

Once, my friend asked me if by teaching others I'm not creating competition for myself.
I get where he was coming from, but that's not how I see it. We aren't in a race, we are in a life-long hackathon. If someone levels up, everyone wins. And I win, too.

Approx. 90% of the code I ship is written by agents, yet I still don't really know what MCPs are.

This one dives into the hard parts of a foreground queue: atomic read–modify–write, enqueue-time deduplication & bounds, and a single-flight sync loop you can safely pause.

Hot take: if your company does not allow engineers to use Cursor or Claude Code, they're actively hurting your career.

Offline writes are the hard part of offline support. I wrote about using a foreground queue to make offline mutations explicit, durable, and predictable.

If you write a prompt, and it obviously sucks — ask AI to turn it into a better prompt and refine from there. Works like a charm.
That's the moment you realise AI is better even at writing prompts. 🙃

Offline support starts long before background sync or queues. The real foundation is data persistence. In this post, I break down how to do this with React Query and IndexedDB.
