🚂 Announcing github.com/rocicorp/rails! 🚂

Rails generates all the setup code for a new @replicache app from simple model definitions.

It makes it absurdly easy to build offline-first, realtime syncing web apps.

How easy? Our todo sample is now just ~150 lines of code 🤯.

🧵… #

Demo: Open replicache-todo.vercel.app in two browsers.

Notice how each mutation is *instant* and syncs in realtime between browsers.

Throttle the network or even disable it. No effect on performance, and the app automatically syncs up when the network comes back. #

Replicache gives you these behaviors by default.

You don't write optimistic mutations. Every mutation is optimistic. You don't write sync code. Everything syncs. You don't even need to write a server. We provide a generic backend that runs Node/Postgres.

Here's how it works: #

Basically Replicache provides an abstraction that feels like fast in-browser storage, but which is magically synced to your server and other users in the background. It is a super fun and productive way to work, and happens to also produce insanely fast and collaborative apps. #
