Fine-Grained Reactivity

Built from the ground up with signals, effects, and memos. FalconJS updates only what's necessary, without a Virtual DOM, leading to exceptional performance.

Modern JSX Syntax

Write your components with the clean, intuitive, and familiar HTML-like syntax of JSX. Our build process handles the transformation to optimized JavaScript.

Complete Feature Set

Comes with a built-in router, global state management, and async data handling primitives, giving you everything you need to build a complete application.

Why FalconJS? ​

Performance by Default

FalconJS was built on the principle that performance should not be an afterthought. By leveraging a fine-grained reactive system, your applications are fast and efficient from the start.

Simplicity and Ergonomics

We believe a powerful framework doesn't have to be complex. With a minimal API and familiar JSX syntax, you can be productive in minutes, not days.

Everything Included

Stop wrestling with libraries. FalconJS comes with a built-in router, global store, and data fetching utilities, providing a cohesive development experience out of the box.

See it in Action ​

FalconJS makes reactivity simple and intuitive. Here is a complete, working counter component that demonstrates the core concepts of signals and JSX.

jsx
import { createSignal } from '@olsigjeci/falconjs';

function Counter() {
  const [count, setCount] = createSignal(0);

  return (
    <div>
      <p>Count: {count()}</p>
      <button onClick={() => setCount(count() + 1)}>Click Me</button>
    </div>
  );
}
