Mastering React Server Components and Server Actions in React 19

Server actions in React are asynchronous functions marked with 'use server'. They allow client-side code to execute functions on the server, simplifying interactions that require server processing.

Benefits include smaller client-side JavaScript bundles, faster rendering, direct server-side data fetching, and improved security by not exposing sensitive data to the client.

React server components run on the server and render once, while client components run in the browser, support interactivity, and can re-render with state changes.

The main topic of the workshop is mastering React server components and server actions in React 19, with a focus on using Next.js 15.

The instructor is Maurits de Beyer, also known as the Problem Solver. He is a freelance developer, instructor, and front-end architect with experience since 1995.

React server components are components that execute on the server. They were created to improve performance by reducing client-side JavaScript bundles and allowing direct server-side data fetching.

The workshop uses Next.js because it supports React server components and provides server-side capabilities necessary for rendering components on the server.

To indicate a component should be a client component, add the 'use client' directive at the top of the component file.

Suspense boundaries can be used to show loading indicators while data is being fetched asynchronously, providing a better user experience.

The 'server only' import ensures that certain code, such as server-side API calls, only runs on the server and not on the client, preventing potential security issues.
