Q & A

What is NextJS and who maintains it?

NextJS is a popular React framework optimized for building SEO-friendly websites. It is built and maintained by Vercel.

Why do companies like Netflix, GitHub, Uber, and Starbucks use NextJS?

These companies use NextJS because it enhances the capabilities of React by providing server-side rendering and static site generation, improving SEO and user experience.

What is the main issue with typical React applications regarding SEO?

Typical React applications are client-side rendered, which means search engine bots cannot index the content properly, leading to poor SEO performance.

How does NextJS address the issue of social media bot previews?

NextJS allows for server-side rendering or static site generation, enabling social media bots to read the content of the page and generate accurate previews.

What is the significance of First Contextual Paint in the context of NextJS?

First Contextual Paint is a core web vital that measures when the main content of a page is visible to the user. NextJS improves this metric by reducing the time it takes for content to be rendered, enhancing user experience.

Can you explain the concept of file-based routing in NextJS?

File-based routing in NextJS allows developers to create pages by simply creating files in the 'pages' directory. The URL structure is automatically generated based on the filenames, eliminating the need for an external router.

What is the role of the getStaticProps() method in NextJS?

The getStaticProps() method is used in static site generation, where it fetches data that will be passed to the page as props. This data is then used to generate static pages that can be cached via a CDN for fast delivery.

How does Server Side Rendering (SSR) differ from Static Site Generation in NextJS?

SSR generates pages on the server each time they are requested, ensuring that users receive up-to-date content. In contrast, Static Site Generation creates pages ahead of time, which is ideal for content that does not change frequently.

What is the purpose of the revalidate key in getStaticProps()?

The revalidate key in getStaticProps() allows for periodic regeneration of static pages, providing a balance between the speed of static sites and the freshness of content.

What new feature does the latest version of NextJS offer?

The latest version of NextJS includes a Rust compiler, which significantly improves the framework's performance.

Why is NextJS considered an enhancement to the powers of React?

NextJS enhances React by providing solutions for SEO, content previews, and improved performance through server-side rendering, static site generation, and built-in features like file-based routing and image optimization.
