🧬 Zero-Runtime · ⚡ Compiler-First · 🧠 Fine-Grained Reactivity
Built in Rust. Outputs <1KB JS. Blazing-fast.

nullReact is a new kind of web framework — not a library, but a compiler-first engine.
It compiles JSX into zero-runtime, reactive JavaScript, with fine-grained signal-based updates — all under 1KB.

Perfect for those who demand raw performance, minimalism, and full control.

• 🛠 Compiler-First — JSX is compiled to highly-optimized JavaScript.
• 🧠 Signals + Effects — Fine-grained reactivity without component rerenders.
• 🚫 No Virtual DOM — Direct DOM operations. Real speed.
• 🧳 Minimal Runtime — Optional runtime under 1KB.
• 🦀 Rust-Powered — Fast, safe, and parallel compilation.

⏱ Benchmark runs: make bench

• 🔥 Reactivity should be compiled, not interpreted.
• 📦 Runtimes should be opt-in, not bloated.
• 📏 Performance should be measurable, not theoretical.
