c3kit-bucket just got a major upgrade — IndexedDB support for ClojureScript.

c3kit is our open-source Clojure framework for building full-stack applications. The core idea behind Bucket, its data layer: write your data operations once, run them against any backend — Datomic, JDBC, in-memory, and now IndexedDB in the browser.

The new IndexedDB implementation enables local-first applications that persist data offline and sync automatically when connectivity returns. No separate offline logic. No rewriting queries. The same clean API everywhere.

Alex Root-Roatch from our team walks through the full implementation — from configuration to sync lifecycle to service worker integration.
