As web applications grow in complexity, optimizing performance is key. React server components are an upcoming React feature that can significantly speed up rendering by allowing components to run server-side.
Let’s take a look at what React server components are and how they offer game-changing speed improvements.
What Are React Server Components?
React server components enable a React component’s logic to execute on the server. This means the component can render to static HTML strings on the server before being sent to the client.
The key benefit is the HTML is already rendered before hitting the browser, removing costly client-side React rendering. The client then “hydrates” the static HTML, binding event listeners to make it interactive.
Some ways server components improve performance:
- No client-side React rendering
- HTML reuse across pages
- Faster time-to-first-byte
- Better SEO
