Question 1

What is the main role of the useState composable in Nuxt?

Accepted Answer

The useState composable creates a reactive shared state that is SSR-compatible. It ensures that state created server-side is properly hydrated client-side, avoiding hydration mismatches between server and client rendering. Each component using the same key accesses the same shared state.

Question 2

Why provide a unique key when using useState?

Accepted Answer

The key allows sharing state between multiple components and ensures SSR consistency. All components using the same key access the same reactive state. Without a key or with identical keys, states mix up and cause hard-to-debug issues.

Question 3

How to correctly initialize state with useState?

Accepted Answer

useState accepts a key and an initialization function that returns the default value. The function executes only once server-side, then state is hydrated client-side. Never put a value directly (useState('key', 0)) as it doesn't work properly with SSR.
