Basic Server Action Forms
Create interactive forms that submit data directly to the server using Next.js Server Actions.
Intro to Server Actions
Welcome to Server Actions! This powerful Next.js 15 feature allows you to define functions that run directly on the server, callable from your client components.
Think of them as a way to send data to your server without needing to create a separate API route. They simplify data mutations and form submissions.
Why Use Server Actions?
Server Actions offer several key benefits for your Next.js applications:
- Simplified Data Mutations: Directly call server-side code from your forms.
- Reduced Client-Side JS: Less JavaScript needs to be sent to the browser.
- Improved Performance: Actions run closer to your database, potentially reducing latency.
- Automatic Revalidation: They can automatically update cached data after a successful mutation (more on this in a later lesson!).
