⚙️ Core Concepts

🔄 Signal-Based Reactivity

SeraJS uses a signal-based reactive system, a modern approach to state management that enables efficient updates:

🧠 Signals

Self-contained reactive values that notify subscribers when they change.

🌀 Effects

Functions that automatically re-execute when their dependencies (signals) change.

🧭 Memo

A memoization helper similar to React's useMemo, used to cache the result of a computation based on reactive dependencies to avoid unnecessary recalculations.

🔬 Fine-Grained Updates

Only the specific DOM elements affected by state changes are updated, resulting in minimal re-rendering and high performance.

💡 SeraJS is designed to be intuitive, fast, and easy to integrate into any

project — making it a perfect choice for modern frontend development.

Why SeraJS?

SeraJS brings together the best parts of libraries like React, Solid, and Lit — blending familiar patterns with a fresh, minimal approach.

At just 1.25KB gzipped and only 135 lines of code, this reactive UI library stays ultra-light while still delivering powerful reactivity.

Whether you want a build system or prefer a no-build workflow, SeraJS has you covered. It’s flexible enough to fit your dev style — use it how you want.

🌱 Sera.js Basic Example

A minimal example showing a Hello World message using Sera.js.

📄 App.jsx

import { h } from "serajs";
export default function App() {
  return (
    
Hello world
  );
}

No Build, No Dependencies
