Fast Vue SSR with Rust and QuickJS

An ongoing experiment using Rust, Warp and QuickJS to server-side render Vue.js applications.

use renderer::RendererPool;
#[tokio::main]
pub async fn main() -> io::Result<()> {
    let pool = Arc::new(Mutex::new(RendererPool::new(64)));
    let renderer = warp::path::full().map(move |path: FullPath| {
        let renderer = Arc::clone(&pool);
        let s = path.as_str().to_string();
        // Currently only passing path to renderer is possible
        // Full Request object is a WIP
        let result = renderer.lock().unwrap().render(s);
        result
    });
    let routes = warp::path::full()
        .and(renderer)
        .map(|_, result| reply::html(result));

So far using a thread pool and channels to communicate with the Warp route handler. The goal is to get a full Node-like IncomingMessage object available as $ssrContext.req. It already includes a /static handler and serves a code-splitted build on the client via Rollup.

Node outperforms QuickJS by a wide margin. Especially with enough cores and memory. However, QuickJS is very small and has very low memory consumption, so running it threaded in a Rust shell makes it possible to have very high throughput using very few resources in comparison.

Inspired by Xinjiang Shao's experiment.

Running

1. Install Rust.
2. npm install
3. npm test

Or npm run build for generating the Rust binary.
