Synclets
@synclets.bsky.social
An open, storage-agnostic, sync engine development kit.
And if you got this far, thank you! This is just the announcement of a forthcoming journey, but please like, star, share, and follow so we can all go on it together.

Our next major milestone will be building out a proof of concept that connects client-side SQLite and PGlite databases to CloudFlare Durable Objects, as we think this might be a popular pattern for many realtime collaborative apps. Stay tuned for announcements on that one!

What's next?
--
The Synclets project is pre-alpha right now, so there is still plenty of work to be done!
There are decent test suites in place for the core components, and some basic documentation, but we still need to build out more connectors, transports, and examples.

Or you could synchronize data between a local SQLite database and a remote PostgreSQL server over WebSockets. PGlite in the browser with CloudFlare Durable Objects. Or, as long as you can implement a few simple methods, between any storage and over any transport you like!

This compositional approach means you have a lot of flexibility for how data flows in your app. For example, you could synchronize an in-memory state in the UI thread of your application with local storage in a worker thread.

The philosophy of Synclets
--
The Synclets project is designed around a few core principles:
1. Be compatible with as many storage backends as possible, whether database-oriented, in-memory, file-based, or otherwise. No vendor lock-in!

(Development on TinyBase will continue as before, but we expect to increasingly use Synclets as the default underlying engine for its synchronization features going forward - making it easier for you to piece together the architecture that best works for you.)

But we figured these techniques would be valuable to people that are not using TinyBase too, and so Synclets is essentially an attempt to extract and generalize these ideas into a standalone project.

The background to Synclets
--
During the development of our sister project @tinybase.bsky.social, we found ourselves needing to build synchronization logic to keep data in sync between local and remote stores - as well as ways to persist them to various storage backends and databases.

This is a very young project, and not ready for production use yet. But we are sharing it in this early form to invite feedback and contributions from the community.

We believe synchronization is a fundamental part of modern app development, especially in the context of rich client and local-first apps. We also believe that you shouldn't be locked into a specific storage solution, transport layer, or vendor in order to do so!

Synclets are intended to make it easy to synchronize data between the different parts of your applications, whether between local storage and remote servers, between different devices, or even across worker boundaries.
