Sigment – Fine-grained reactive JavaScript, no VDOM or JSX.

The fine-grained reactive framework for building lightning-fast apps — no virtual DOM, no JSX, no transpilation.

Why Sigment?

React With JSX

function App() {
  return (<div>Hello World!</div>);
}

Sigment (No JSX)

function App() {
  return div('Hello World!');
}

⚙️ Sigment is built without a virtual DOM or JSX. It uses real DOM operations and plain JavaScript functions, allowing you to write clean, modern code with zero build tools.

✅ Clean code: No mixing of HTML inside JavaScript
⚡ Short & readable: Less boilerplate and fewer lines of code
🚀 Faster compile time: JSX adds a transpile step — Sigment skips it

⚡ Fine-Grained Reactivity

Only the parts that need to change update — no diffing, no overhead.

🚫 No Virtual DOM

Sigment updates the DOM directly, making your UI faster and simpler.

📦 Ultra-Lightweight

A minimal runtime and zero config setup means less to worry about.

🧠 Developer Friendly

Built for modern developers — readable syntax, powerful tools, and no need for build steps.

🛠 No JSX, No Transpiler

Just write JavaScript — tag functions like div() and button() build your DOM directly.
