SSR framework for React.js built on MetaCall

MetaSSR is a powerful experimental Server-Side Rendering (SSR) framework crafted for high-performance, dynamic web applications. MetaSSR uses Metacall Runtime, exploring web-based use cases for polyglot programming.

Why MetaSSR?

MetaSSR has a great performance potential, performing significantly better than other more mature production 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

Key Features

• Rust-Powered Performance: Enjoy the speed and safety of Rust in your server-side rendering tasks.
• High Performance: Achieve fast load times and excellent user experiences with optimized server-side rendering.
• API Route with Polyglot Programming: Integrate multiple languages in the backend with Metacall's support.

Getting Started

To get started with MetaSSR, follow these steps:

1. Installation: Review our Installation Guide to install MetaSSR on your system.
2. CLI Documentation: Learn how to utilize the MetaSSR CLI with our CLI Documentation.

Contributing

We welcome contributions from the community! If you're interested in helping out, please check out our Contributing Guide for information on how to get involved.

For running a development environment:

Docker

docker build --target build_debug -t metacall/metassr:dev -f Dockerfile.dev .
docker run --rm -it metacall/metassr:dev bash

Nix

1. Install Nix (if not already installed):

   sh <(curl --proto '=https' --tlsv1.2 -L https://nixos.org/nix/install) --daemon

2. Enable Nix Flakes:

   mkdir -p ~/.config/nix
   echo "experimental-features = nix-command flakes" >> ~/.config/nix/nix.conf

3. Enter Development Shell:

   nix develop

This will automatically set up Rust, MetaCall, and all required dependencies, same dependencies for all of us developing.
