SnapFire FSR

Build web apps in TypeScript. Serve them from Rust.

Routes, loaders, actions and layouts, the shape you already know. Write the pages as React and TypeScript or as Tera templates. Either way what renders them is Rust.

Rendered in RustYour React and TSX pages, server-rendered with no JavaScript engine

One binary to shipNothing to install on the box, no Node to keep patched

Flagship

SnapFire FSR

Web applications in TypeScript, served by Rust.

The application is TypeScript under app/. The runtime is Rust. Loaders and actions are read at build time and become data the host executes directly, so nothing in the serving path is a JavaScript engine.

Native SSR of React pages with no JS engine
Typed service calls generated from OpenAPI and Protobuf
Server islands, sessions and identity in the host

Supporting

SnapFire Compiler

A TypeScript and CSS compiler for the browser.

Compiles TypeScript to browser-native ES modules with no Node and no node_modules. FSR uses it to bundle the client half; it knows nothing about FSR and works on its own. Its binary is snapfirec.

Native, SWC-backed, no toolchain to install
Source maps, minification, import maps
A preload manifest for what the page needs first

Where it started

snapfire

Tera templates over Actix, with live reload.

The original crate: a templating library with an integrated zero-configuration reload server. Edit a template, the browser updates. Every development-only feature compiles out of a release build.

First-class Tera 2 and Actix Web integration
Live reload with no configuration
Nothing development-only in a release binary
