Answer
Server actions allow calling server-side functions directly from components without creating API endpoints, reducing boilerplate and enhancing security.
Quick Answer
Server actions in React 19 are async functions that run on the server, called directly from components — no need to create a separate API endpoint, set up fetch calls, or manage CSRF tokens. They're more ergonomic than REST calls and can directly mutate server data, then optionally revalidate the component tree.
