Local-first and Sync Engines, the Architecture of the Future?
summary
The talk explains the local-first application pattern and the synchronization engines that make it work, contrasting it with traditional request-every-interaction designs. It covers how local-first apps (examples: Linear, Figma, Trello) keep data primarily on the client, enable offline use and instant UI responsiveness, and use sync engines to reconcile and propagate changes. The talk also outlines core principles of local-first, describes what a sync engine does, and gives examples of libraries and databases that implement these approaches.
