The Power of Server Components

React Server Components represent a fundamental shift in how we think about building web applications. Instead of shipping all your component code to the browser, Server Components run exclusively on the server — sending only the rendered output to the client.

At Pulse, this has been transformative. Our blog posts don't need interactivity to display content, so there's no reason to send React's rendering logic to the browser for static text. Server Components let us keep that code where it belongs: on the server.

Less JavaScript, Faster Pages

The average web page ships over 400KB of JavaScript. Much of that is framework code needed to render components that never change after the initial load. Server Components eliminate this overhead entirely for static content.

Our blog pages now ship a fraction of the JavaScript they used to. The result? Faster load times, less battery drain on mobile devices, and a smoother reading experience overall.

Mixing Server and Client Components

The real power comes from combining Server and Client Components. Our post content renders on the server, but interactive elements like the newsletter signup and navigation animations use Client Components. This hybrid approach gives us the best of both worlds.

Think of it like a newspaper: the articles are printed (server-rendered), but the crossword puzzle is interactive (client-rendered). You wouldn't re-print the entire newspaper just to let someone fill in a crossword.

The Future of React

Server Components aren't just a performance optimization — they're a new mental model for building applications. As the ecosystem matures, we expect to see even more creative uses. The boundary between server and client is becoming a tool we can use deliberately, rather than a limitation we work around.
