Clean Coders

Happy 4th of July from all of us at Clean Coders!

This year marks the 250th anniversary of the signing of the Declaration of Independence. Milestones like this remind us that the things built to last are created with intention, maintained with care, and designed to evolve.

We bring that same mindset to software.

Clean, well-crafted code is its own kind of investment in the future. It reflects respect for the people who will use it, maintain it, and build upon it years from now. At Clean Coders, readability, reliability, and adaptability are not just technical checkboxes. They are the foundation of craftsmanship.

As we celebrate the 4th of July with family and friends, we are also reflecting on the values that drive us every day: dedication, care, and the commitment to building software that stands the test of time.

Wishing you a safe and happy 4th of July.

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.
