It would be great, right? So, carry on reading this article because you are going to find an optimum solution for lots of your web designing problems. Next.js comes with the entire configuration you need to begin using it so you don’t have to worry about it.  

What is next js?

In simple terms, Next.js is a Javascript framework designed by Zeit. This tool is excellent in creating your NEXT website. With next.js you will be able to build static web applications and server-side rendering by using React. There are so many great benefits and features that this tool possesses that can make Next.js your priority for web application designing.  

What is React?

Before we move further into the details of Next.js, let us first tell you what React is. It is a javascript library that assists in making user interfaces. This tool is handled by Facebook, some individual companies and developers. It is used to make single page mobile applications.

React manages the view layer for mobile and web applications. Not just this, it helps in building UI components that can be reused. Jordan Walke; a software engineer was the first person who developed React for Facebook. In 2011, it was first implemented on Facebook’s newsfeed and in the very next year on Instagram.

Through React, develops can design large applications which allows data change without actually refreshing the page. React is scalable, efficient, and simple. It can also be termed as ReactJS or React.js.

Advantages of next js:

Next.js is a must-have tool because of all the advantages that it has:

Easy to use:

One of the major benefits of this tool is that it is easy to begin with. There are many other tools available but they require complex understanding and a lot of time. On the contrary, next.js is simple to understand and start.

To create the shell for an app, below is all that you need:

npm init -y # creates package.json
npm install react react-dom next # installs necessary dependencies
mkdir pages && touch pages/index.js

Automatic Code Splitting:

Any developer nowadays will disclose to you how significant code splitting is to guarantee an application’s presentation is ideal. As its name proposes, code splitting enables us to part our application code up into a progression of lightweight packs. Rather than stacking the entirety of our JavaScript, our application will just load the pack required. Webpack is the instrument most connected with this procedure. Rather than arranging a web pack to play out this, we can depend on Next.js.

Prefetching:

Prefetching starts from the point where the code splitting is left off. With the help of Next.js, each of the advanced packs of code is loaded behind the screen.

To take advantage of this feature, the “prefetch” attribute has to been added to the link components.

// it will not fetch the code

<Link href=”/blog” />

// it will fetch the code

<Link prefetch href=”/blog” />

HMR and Error Reporting:

With the help of HMR, rather than refreshing the whole application when a developer changes the code, it only reproduces those modules who have been amended. Not just this, it quickly tells the error that has been made and renders to the browser immediately. Even a small error can cause a headache. Next.js instantly pinpoints the errors to make it easier for us to correct it.

Server-side rendering:

What is Server-Side Rendering? It is a mainstream method that renders a typical customer side single page application (SPA) on the server and transfers a completely rendered page to the customer. The customer’s JavaScript pack would then be able to dominate and the SPA can work as typical. One significant advantage of utilizing SSR is in having an application that can be crept for it’s in any event, for crawlers that don’t carry out the JavaScript code. It helps with Search Engine Optimization and spreading Metadata information to various social media platforms.

CSS in JS:

CSS is already built-in the Next.js and you don’t need to install any other package.

What is Gatsby?

Gatsby merges the best parts of GraphQL, webpack, react-router, React and many other front-end tools to make one better-developing tool.It is a static site generator that is built on ReactJS. In general terms, a static website is something that contains a lot of HTML pages and at each visit, it doesn’t drag any kind of data from the database. It looks kind of similar to every person who visits. They are much quicker in loading as the same response is been sent to every visitor. But it doesn’t allow the content to be customized for different visitors.

How Next.js are Gatsby and vice versa?

Next.js v/s Gatsby:

Both of these look quite the same. They give you a platform to build web applications. They both create incredibly accessible, efficient and SEO friendly websites. So, what’s the difference? Here it is,

Next.js is essentially a tool that works for server-side rendered pages. It progressively creates the HTML each time another solicitation comes in with the utilization of a server.

Gatsby is a static site generator apparatus. A static site generator creates static HTML on assemble time. It doesn’t utilize a server.

Both can command APIs customer side. The basic distinction is Next requires a server to have the option to run. Gatsby can work with no server by any stretch of the imagination…..
