RxFerrixA reactive backend in Rust

Write typed Rust functions. Clients get live results. Ship it all as one binary.

⚡

Live by default

Clients subscribe to queries, and results update by themselves whenever a write changes the data they read. No cache to invalidate, no refetching to write.

🦀

Typed end to end

Rust structs are the schema. A TypeScript API is generated from your functions, for React and Svelte.

📦

One file to deploy

SQLite is embedded, and so is your frontend if you like. Copy the binary to a server, or use the Docker image, and start it.

🔁

Deploys without downtime

A new version prepares next to the running one and takes over in well under a second, without losing a write. One that can't read the data steps back.

🔋

Batteries included

Auth, file storage, crons, durable workflows, full-text and vector search, live aggregates, analytics and migrations.

🛠️

An admin dashboard

Browse and edit data live, run functions, tail logs, manage users, files, backups, migrations and settings, at /_/ in every server.

What it looks like

A table and two functions on the server:

rust

// src/todos.rs
use rxferrix::prelude::*;

#[table(name = "todos")]
pub struct Todo { pub text: String, pub done: bool }

#[query]
pub async fn list(ctx: &QueryCtx) -> Result<Vec<Doc<Todo>>> {
    ctx.db.query::<Todo>().order(Order::Desc).take(100).await
}

#[mutation]
pub async fn add(ctx: &MutationCtx, text: String) -> Result<Id<Todo>> {
    ctx.db.insert(Todo { text, done: false }).await
}

// src/main.rs
mod todos;
fn main() -> rxferrix::Result<()> { rxferrix::RxFerrix::new().run() }

And a React component that uses them. When anyone adds a todo, every open list updates:

tsx

import { useMutation, useQuery } from "@rxferrix/react";
import { api } from "./rxferrix"; // generated from the functions above

function Todos() {
  const todos = useQuery(api.todos.list);
  const add = useMutation(api.todos.add);
  return (
    <>
      <button onClick={() => add({ text: "Buy milk" })}>Add</button>
      <ul>{todos?.map((t) => <li key={t._id}>{t.text}</li>)}</ul>
    </>
  );
}
