nextjs-client-cookie-pattern

Next.js client components can set server-side cookies by invoking server actions that use next/headers for cookie manipulation. This pattern securely handles client-triggered state changes, ensuring sensitive logic remains server-side.

Managing authentication tokens in Next.js server actions involves using next/headers to apply httpOnly, secure, and sameSite attributes. This ensures robust security for session data triggered by client-side actions.
