A hands-on workshop building a multiplayer chat app with Jazz — demonstrating how local-first shared state replaces traditional backends, databases, and file storage with a single reactive abstraction.
Sync Engines for Vue Developers
by alexander-opalic
Vue already syncs your refs to the DOM. Sync engines extend that same idea to databases — keeping client state and server state in harmony. Here's how Replicache, Zero, Convex, PowerSync, LiveStore, Jazz, and Dexie each approach this differently.
