Efficient Client-Server Communication with Differential Synchronization and JSON Patch

on YouTube ↗01h 20m

" summary

Differential Synchronization plus JSON Patch reduces many REST calls to a single atomic request by sending only deltas, demonstrated by batching many creates/updates/deletes into a single HTTP PATCH instead of dozens of PUT/POST/DELETE calls. A Java server-side library (spring-sync) applies patches directly to Java object graphs; a client library (jiff.js) diffs and patches JS objects and DOM. Demos show multi-client realtime sync over STOMP and websocket streaming, undo/redo via patch algebra, and a working snapshot release for experimentation.
