From the PWA foundations (Service Workers, Workbox 8, IndexedDB, OPFS) to client-side sync engines like Replicache, Zero, RxDB, ElectricSQL, and PowerSync, the CRDT trio Y.js, Automerge, and Loro, the next-generation local-first databases LiveStore, Triplit, InstantDB, and TanStack DB, and real-world architectures from Linear, Figma, Notion, and Tldraw.
