Скачать или смотреть NextJs 15 : ✅ Fix useActionState Error by Separating Server Action in Next.js

In this video, we solve a common error in Next.js App Router when using useActionState alongside a server action.
Since useActionState is a client-side React hook, combining it with a server action like CreateProduct in the same file leads to an error ❌.

🎯 In this tutorial, we’ll fix this by separating the server action into its own file and ensuring a clean, maintainable structure.
By the end, you’ll have a fully working solution with clear separation between client and server logic 💡.
