Server Actions (Next.js)
💡 Quick Definition: Asynchronous functions in Next.js that execute securely on the server and can be invoked directly from Client Components or HTML forms without manually writing REST API endpoints.
Detailed Explanation & Workplace Application
Server Actions simplify data mutations, form submissions, and database queries. They automatically handle POST requests, provide progressive enhancement, and integrate seamlessly with Next.js revalidation and caching.
Practical Syntax / Framework Formula
'use server';
export async function submitQuizScore(formData: FormData) {
const email = formData.get('email');
await db.leads.create({ data: { email } });
revalidatePath('/dashboard');
}
