Brahma-JS: Ultra-Low Latency JS Runtime Powered by Rust
Rust is amazing for speed, safety, and stability—but let’s be real: most JS/TS devs don’t want to wrangle the borrow checker, strict type system, and ownership rules just to build web APIs.
That’s why I built Brahma-JS — an ultra-low latency runtime written in Rust on top of Tokio + Hyper, but plug-and-play with Node, Deno, and Bun.
🔥 What it does
- All heavy lifting (
req.body, headers, query parsing, etc.) runs in Rust. - Works directly inside your existing JS ecosystem (Node, Deno, Bun).
- Fire-and-forget, fully sync-style architecture.
- Lets you write type-safe, memory-safe, blazing-fast HTTP routes with the simplicity of JS.
✨ Example with installation
const { useBrahma, startServer, redirect } = require("brahma-firelight");
useBrahma((req) => {
if (req.path === "/hi") {
return {
headers: { "Content-Type": "application/json" },
status: 200,
body: JSON.stringify({ message: "Hello World from Brahma-JS!" }),
};
}
if (req.path === "/bye") {
return redirect("https://example.com");
}
return {
status: 404,
body: "Route not found",
};
});
const port = process.env.PORT || 3000;
const host = process.env.HOST || "0.0.0.0";
startServer(host, +port).then(() => {
console.log(`🌀 Brahma-JS server running at http://${host}:${port}`);
});
⚡ Benchmarks
On a tiny AWS EC2 t2.micro, I hit:
- 33.2k req/s within 10s of load testing
- No proxy, no hacks — just raw Rust (Hyper + Tokio) under the hood Benchmarks August 2025
(That’s significantly faster than Express/Fastify on the same hardware.)
🔗 Try it out
🙌 Looking for feedback
- Star ⭐ the repo if this excites you
- PRs welcome for early testers
- Drop issues with the features you’d want next
Nobody needs to give up their ecosystem anymore. Write JS, run at Rust speed. ⚡
