State Management in Qwik

Qwik provides several powerful ways to manage state in your applications. Let's explore them in detail.

Signals

The most basic form of state management in Qwik:

import { component$, useSignal } from "@builder.io/qwik";

export default component$(() => {
  const count = useSignal(0);

  return (
    <div>
      <p>Count: {count.value}</p>
      <button onClick$={() => count.value++}>Increment</button>
    </div>
  );
});

useStore

For more complex state objects:

import { component$, useStore } from "@builder.io/qwik";

export default component$(() => {
  const state = useStore({
    user: {
      name: "John",
      age: 30,
    },
    preferences: {
      theme: "dark",
    },
  });

  return (
    <div>
      <h1>Welcome {state.user.name}!</h1>
    </div>
  );
});

Best Practices

1. Use signals for simple values
2. Use stores for complex objects
3. Keep state close to where it's used
4. Avoid unnecessary state updates
