Server Actions in Next.js 14

Server Actions let you call backend logic directly from your components without writing API routes.

🧠 How it Works

  1. Declare a function with 'use server'
  2. Pass it to a form or trigger it programmatically

Example

ts
'use server'; export async function submitData(formData: FormData) { // Handle DB logic }

🔥 Benefits

  • Simpler code
  • No API routes
  • Closer to the React mental model
