5 Main Features of Next.js

Next.js has gained popularity among developers due to its distinct features that enable developers to build sophisticated web applications with flexibility and minimal setup.

Here are some of the main features that make Next.js a standout framework:

1. Incremental Static Regeneration (ISR)

Incremental Static Regeneration (ISR) allows Next.js to combine the benefits of static site generation with dynamic content updates. It enables pages to be generated at build time and then selectively updated as new requests come in. This means that only specific pages are regenerated, rather than having to rebuild the entire site.

For example, a news website can use ISR to generate static pages for articles at build time to ensure fast load times. When new articles are published or existing ones are updated, Next.js can regenerate those specific pages without modifying anything else on the site.

2. Custom Head Tags

Example of 'next/head' tag

The ‘next/head’ component in Next.js offers a simple yet powerful way to manage the HTML document’s <head> section on a per-page basis. This feature allows developers to dynamically set meta tags, titles, and other head elements, which are crucial for SEO and proper social media sharing.

For instance, an eCommerce site can use ‘next/head’ to dynamically adjust the meta title, description, and open graph tags for each product page. This ensures that when a product page is shared on social media, the correct information is displayed, which improves both optimization and user experience.

3. Customizable Functions

Next.js provides functions like ‘getInitialProps’ and ‘getServerSideProps’ to give developers control over how data is fetched and passed to components. The function ‘getInitialProps’ can be used for both SSR and SSG, while ‘getServerSideProps’ is specifically for SSR to fetch data at request time.

For example, in a weather app, ‘getServerSideProps’ could be used to fetch the latest weather data from an API each time a user requests the page. This allows users to receive the most up-to-date weather information.

Next.js includes the ‘next/image’ component, which automatically optimizes images for different screen sizes and devices. This feature supports responsive images, lazy loading, and on-the-fly optimization.

For example, a blog site can use ‘next/image’ to display images perfectly optimized for mobile devices. This ensures that images load quickly on smaller screens while maintaining high quality on larger displays.

5. Fast Refresh

Fast refresh allows developers to see the results of their code changes instantly without losing the state of their app. This is especially beneficial when operating on complex components or forms, where maintaining the current state is crucial for debugging and various testing methods.

For instance, when building a form with multiple input fields, fast refresh ensures that the form’s state — such as user inputs — remains intact when you update the code. This allows developers to continue their work without having to re-enter data or reset the application.
