What is NextJS and Why you should use it?

Next.js is a React framework for building single-page JavaScript apps. This framework has several benefits for both the development team and clients. Users may become increasingly irritated when websites and apps take longer than milliseconds to load. There are many good reasons to use Next.js.

Reasons for using NextJS for your next project

· NextJS is renowned for its quick installation when starting a new project and for its smaller dependency size and ability to only load, the JavaScript and CSS required for any given page.

· The foundation of the file-system-based router is the idea of pages. This means that as soon as a file is added to the page’s directory, it becomes immediately accessible as a route. Also supported are nesting files.

· In addition, NextJS offers a Commerce Shopify Integration with a provider-agnostic user interface, allowing you to bring any headless e-commerce system of your choosing. Since e-commerce is one of the industries embracing NextJS at one of the fastest rates, you should be ready. You should put your faith in NextJS just like significant corporations such as Apple, McDonald's, and Nike has done.

NextJS is highly flexible and quick to respond. NextJS ensures that websites and web apps are responsive across all devices and screen sizes. This means they can use any device they like to browse your website or online app.

When a page is loaded in a browser using Next.js, Google will be aided in its ability to index the HTML-formatted material of your website. 

As a result, a search engine will have an easier time indexing your site, boosting your site's ranking.

The possibility for visitors to the site will improve if it is easier to find in search engines. And that's why Next.js is an excellent search engine optimization framework.

Using NextJS Analytics, it is possible to measure and act based on actual user performance.

Images can have their quality automatically improved via the built-in Image Component and Automatic Image Optimization feature, which uses the updated next/image component. NextJS enables you to design personalized pages, such as 404 and 500.

How Does It Work?

Your React application or website can be rendered on a server using Next.js (as opposed to being generated on the client side).

It is important to remember that you will require a server of some kind.. somewhere.

The primary advantage offered by this solution is that it supports circumstances in which data must be updated in real-time.

As for the drawbacks of server rendering:

·  Higher complexity: anticipate writing more code to have things working correctly.

·  It becomes more complicated when working with third-party providers.

·  a little more complicated to implement (compared to client-side rendering and HTML)

Next.JS Features

So, what characteristics will make your work more productive?

Routing Pages

The Next.js router is a core feature because it is built on the concept of pages. To use the React switch, developers must write code within the React framework.

Adding a new switch’s description to the directory pages is necessary. You should utilize the Link component to go to different web pages.

Built-in CSS Support

You can import CSS data from a JavaScript file using Next.js. This is plausible given that Next.js expands the concept of importing beyond JavaScript.

All styles between style jsx>/style> labels are split for specific pages because Next.js uses styled-jsx by default for CSS.

Considering this, we don’t have to worry about overwriting them. Styles are created on both the client and server sides, so we can see a legitimate design as soon as we enter a website.

Naturally, this configuration has benefits and drawbacks, but fortunately, Next.js makes it easy to set up this component without the need for styled-jsx.

The fundamental approach is to use inline styles, and you can do this by using CSS-in-JS.

Layout Component

We can easily reuse our component on the other page by refactoring the page constructor in Next.js into a group component.

For instance, we may reuse the same header component across all the pages instead of generating a new header script for each website page.

Image Optimization

The Image Component and Image Optimization are available in Next.js.

The HTMLimg>component expansion required for cutting-edge applications is referred to as the “Image Component.”

When using image optimization is simpler to create, resize, and serve images in setups, and it doesn’t transmit large images to devices with smaller viewports.

Next.js can support future image formats, and all of them can be served to browsers that support them. Any picture source can be used with it. Whether the photographs come from an outside source, they can be updated.

Font Optimization

To speed up the declarationSpl font process, Next.js, by default, sets up inline font CSS automatically during the build step. This will facilitate the effective loading of fonts on a page.

Script Optimization

We may organize the prioritized loading of the third-party script using the Next.js script component.

You have three scripts, for instance, to analyze content, manage advertisements, and manage social media widgets. Placing the studied content on the first line of the script will prioritize it.

This will quicken the website’s loading time and stop a page from having material that isn’t visible.

Serving static files

You can export a fully static site from your app using Next.JS following export command.

Quick Refresh

The Next.js feature known as Fast Refresh will immediately refresh the page after the script is modified.

Because it will benefit us, developers, we didn’t need to reload the page manually after upgrading the script.

This is to give you an idea of the projects that benefit from Next JS development. The promising framework Next.js has many excellent features that increase developers productivity and lighten their workload.

Next.js is a popular framework with many distinctive features that have made it a favorite among developers.
