What are some tips for improving performance in React SSR?

To enhance performance in React Server-Side Rendering (SSR), consider the following tips: 1. Optimize data fetching by using techniques like caching and batching. 2. Minimize the size of your server-rendered HTML by avoiding unnecessary components. 3. Use code splitting to load only the necessary JavaScript for the initial render. 4. Implement lazy loading for images and other resources. 5. Monitor performance with tools like Lighthouse.

How can I optimize data fetching in my SSR app?

You can optimize data fetching by using techniques such as: 1. Caching responses to avoid redundant requests. 2. Using a data-fetching library that supports batching, like React Query. 3. Prefetching data during the server render to ensure it's ready when the client loads.

What is code splitting and how does it help?

Code splitting is a technique that allows you to split your code into smaller chunks, which can be loaded on demand. This helps improve performance by reducing the initial load time, as only the necessary code for the initial render is sent to the client, while other parts are loaded as needed.

Can you recommend any tools for monitoring performance?

Sure! Some popular tools for monitoring performance include Google Lighthouse, WebPageTest, and New Relic. These tools can help you analyze your app's performance and identify areas for improvement.
