What is noSsr

noSsr stands for “no Server-Side Rendering” and is a feature in React.js and React Native that allows components to be rendered only on the client-side. This means that the component will not be rendered on the server-side during the initial page load, but will instead be rendered on the client-side after the page has loaded.

How does noSsr work

When using noSsr, the component is wrapped in a higher-order component that checks if it is being rendered on the server-side or the client-side. If it is being rendered on the server-side, the component is not rendered and is instead rendered on the client-side after the page has loaded.

Benefits of using noSsr

One of the main benefits of using noSsr is that it can improve the performance of your application by reducing the amount of server-side rendering that needs to be done. This can lead to faster load times and a better user experience.

When to use noSsr

noSsr is typically used for components that do not need to be rendered on the server-side, such as components that rely on client-side data or interactions. It is especially useful for components that are not critical to the initial page load.

Limitations of noSsr

One limitation of using noSsr is that it can lead to a flash of unstyled content (FOUC) on the client-side, as the component is not rendered until after the page has loaded. This can be mitigated by using CSS-in-JS solutions or other techniques to style the component.

Best practices for using noSsr

When using noSsr, it is important to carefully consider which components should be rendered on the client-side and which should be rendered on the server-side. It is also important to test the performance of your application with and without noSsr to ensure that it is improving performance as expected.

Examples of using noSsr

One common use case for noSsr is for components that rely on client-side data, such as dynamic forms or interactive elements. By using noSsr, these components can be rendered on the client-side without impacting the initial page load.

Conclusion

In conclusion, noSsr is a powerful feature in React.js and React Native that allows components to be rendered only on the client-side. By carefully considering when and how to use noSsr, you can improve the performance of your application and provide a better user experience.
