Server Components Are Changing How Web Apps Get Built

React Server Components, and the equivalent patterns now showing up in other frameworks, split a page into components that run only on the server and components that also run in the browser. That distinction sounds small, but it changes how a web app should be architected from the ground up.

What actually changes

Server components can query a database, read a file, or call an internal API directly, without shipping any of that code (or its dependencies) to the browser. Only the components that genuinely need interactivity get hydrated client-side. The result, done well, is a much smaller JavaScript bundle and a faster initial load, without giving up interactivity where it matters.

Where teams get it wrong

The most common mistake is treating server components as a drop-in replacement for the old architecture rather than a reason to rethink data fetching. Teams that keep fetching data in client components “because that’s how we’ve always done it” get none of the benefit and extra complexity instead.

The pattern is still young enough that tooling and conventions are shifting month to month, which is exactly why it is worth having a team that builds with it regularly, rather than picking it up mid-project.
