Offline Sync in the Browser Without a Framework

Short summary

This tutorial introduces ctrodb, a zero-dependency browser database with a sync plugin for building offline-first apps without heavy frameworks like Firebase or RxDB. It walks through setting up push-pull sync over HTTP, configuring auto-sync intervals, handling record-level conflicts, and using React hooks for sync status UI. The author honestly outlines limitations: no real-time collaboration, no automatic field-level merge, and no offline auth token refresh.
