Nuxt state management and hydration with useState

Nuxt hydration and rendering modes

• Nuxt offers Universal mode (SSR) and Client-side rendering (CSR) modes for rendering.
• SSR involves rendering initial HTML on the server, while CSR involves client-side rendering.
• Hydration is the process of converting server-rendered HTML into interactive HTML.

Hydration mismatches

• Hydration mismatches can occur when server-rendered and client-rendered states conflict.
• Server renders initial state, client reinitializes it, leading to discrepancies.

Nuxt state management with useState

• useState is used in Nuxt for creating reactive variables for component-level states.
• useState can lead to hydration issues when controlling initial DOM rendering.
• Use once: true to create state only on the server, preventing reinitialization on the client.

Preventing hydration issues with useState

• Use useMemo to create cached state and prevent reinitialization.
• Clear cached state with useMemo and a key to avoid hydration mismatches.
• Modify state with useState for automatic hydration handling.

Useful tools for hydration mismatch
