Is Morph React? Can I Use React?

Part of: Questions & Answers · The Story of Morph

It's React-inspired — but it's not React, and you can't drop in the React library.

Morph shares the ideas that made React popular: components, JSX, state, effects, declarative UI:

function App() {
  const [count, setCount] = morphState(0)   // just like useState
  morphEffect(() => { ... })                 // just like useEffect
  return <button onClick={() => setCount(count + 1)}>{count}</button>
}

But the machinery underneath is different in a fundamental way. React's core is the virtual DOM — a JS representation of the UI that reconciles changes against the real DOM. Morph has no DOM and no virtual DOM. The layout tree is the real thing:

• No reconciliation — state changes mark exactly the affected nodes in the layout tree and re-render them
• No diffing — you don't diff two trees; you invalidate and redraw the changed nodes directly
• No fibers — the runtime is native; scheduling and rendering are the runtime's job, not a JS scheduler's

So: if you know React, you'll feel at home with the primitives. But it's a native system wearing familiar clothes — not React ported to the desktop.
