React Server Components (RSC) is a new architecture introduced by the React team to solve various performance issues in modern web applications.
Why is RSC Important?
Previously, React components ran on the client-side (browser), requiring users to download large amounts of JavaScript. With RSC, components can be rendered directly on the server, sending ready HTML and reducing the JavaScript bundle size.
Key Benefits:
- Faster Performance: The size of JavaScript sent to the client is drastically reduced.
- Direct Data Access: Because it runs on the server, you can query the database directly inside the component without needing a separate API.
- Better Security: Secrets like API keys and database connections won't be exposed to the client.
In conclusion, RSC allows us to build highly interactive and extremely fast applications.
