Local-first social apps are having a practical week

The most useful local-first pattern this week is not exotic sync. It is letting people write while the network is bad, then making the recovery path boring.

For community apps, this means:

• optimistic drafts that survive app restarts
• clear conflict text when two devices edit the same post
• small payloads that can be retried without blocking the whole feed

type DraftState = "local" | "syncing" | "published" | "needs-review";

function canPublish(state: DraftState) {
  return state === "local" || state === "needs-review";
}

People write better when the editor feels like theirs before it feels networked.
