SSR framework for React.js built on MetaCall

MetaSSR is a powerful Server-Side Rendering (SSR) framework crafted for high-performance, dynamic web applications. Built on Rust and leveraging the Axum web framework, MetaSSR integrates seamlessly with the Metacall Runtime, showcasing a real-world use case for polyglot programming. It was created as part of Google Summer of Code 2024 by Mohamed Emad, to demonstrate the capabilities of polyglot programming.

Why MetaSSR?

MetaSSR delivers exceptional performance that sets it apart from traditional SSR solutions. Built with Rust and optimized for speed, it significantly outperforms conventional Node.js-based SSR frameworks.

Here's how MetaSSR compares to Next.js under high load (12 threads, 1000 connections, 30s):

Metric	MetaSSR	Next.js	Performance Gain
Requests/sec	98,420.11	3,170.95	31x faster
Average Latency	8.63ms	119.90ms	14x lower
Transfer/sec	4.98GB	37.95MB	134x higher
Total Requests	2,962,418	95,326	31x more
Max Latency	65.22ms	1.99s	30x lower
Socket Errors	0	239 timeouts	Zero errors
