Hi HN, James, Valter, Sam and the team from ElectricSQL here. We're really excited to be sharing ElectricSQL with you today. It's an open source, local-first sync layer that can be used to build reactive, realtime, offline-capable apps directly on Postgres with two way active-active sync to SQLite (including with WASM in the browser). Electric comprises a sync layer (built with Elixir) placed in front of your Postgres database and a type safe client that allows you to bidirectionally sync data from your Postgres to local SQLite databases. This sync is CRDT-based, resilient to conflicting…

I launched NumPad v1 on here a few years ago, and back then it wasn't much more than a thin CodeMirror wrapper around the calculator engine I'd written. Now I've rewritten it as a PWA that supports multiple documents, persists them to IndexedDB, and has a syncing service for paying customers. Syncing is handled by Automerge[1] under the hood, which should make it relatively easy to get document sharing working too. [1] https://automerge.org/

Hey HN, I want to share with you something I and my four colleagues have been working on for the last several years. It’s a whiteboarding and notes tool called Muse[1]. We just released a 2.0 version which includes local-first sync. A little backstory: I’m one of the authors of the 2019 essay Local-first software[2]. (Past HN discussions[3][4].) The thesis is to reclaim some of the ownership over our data that we’ve lost in the transition from filesystems to cloud/SaaS. So I’m excited to bring CRDT technology “out of the lab” and into a commercial product as a chance to prove the value…

Hi HN. I've been working on an Elixir library for synchronising state, maintained by the server, to connected web clients. I found this was something I kept implementing for side-projects, so I've extracted it into a library. It solves a similar problem to Phoenix LiveView, but aimed at a different level of abstraction: rather than synchronising HTML and UI events, this just synchronises (JSON-serialisable) state. Topics can be shared between connected users, and each client can subscribe to multiple topics. The library takes care of starting topic instances (GenServer processes) as needed,…

I created Pylon to make it easier to move from hobby projects to full production apps. When I work on hobby projects, I usually use React or Next.js because they are quick to set up and easy to deploy on Vercel. For production apps, I separate the frontend and backend, then deploy the backend on AWS. But setting up a full backend on AWS can be complex and costly, especially for simple apps. Pylon is a full-stack, real-time framework that includes server-rendered React, TypeScript functions, entities, policies, real-time sync, built-in authentication, and support for background and scheduled…

Hi everyone, I've been working on this thing for a while. It transpiles Haml into Ruby, and then it streams patches to the browser which update the DOM. There is a memory leak in s.rb, which I'm not really sure how to solve. Seems like objects stay alive for longer than they should because of circular references or something but I'm not sure what's going on to be honest. I think this approach has potential though.
