How does Nextjs work
Next.Js- How it works and its usage!
It is best for you if you have zero to little information about next.js, you have used React in the past, and you’re looking forward to diving extra into the React ecosystem, in particular server-facet rendering. With this let’s start our topic “How does Nextjs work”!
I find next.js a super tool to create web programs, and on the quit of this put up I hope you’ll be as enthusiastic about it as I’m. And I hope it will help you examine next.js!
Next.js is React framework to perform all of this in a very easy way, but it is now not constrained to this. It’s marketed by means of its creators as a zero-configuration, single-command toolchain for React apps.
It offers a commonplace structure that permits you to without problems build a front-end React software, and transparently handles server-side rendering for you.
Process for getting started with Next.js
First of all, for next.js you should have node.js installed on your system and that’s all. Next.js is like any other node.js application — you need npm or Yarn to install dependencies.
First step- you have to create a folder and give it a name of your preference. we will name it nextjs-app.
After developing the nextjs-app folder, open it at the terminal. Run npm init command to create the package.json file.
After that, we must deploy our dependencies.
installing next.js, using Yarn, type
yarn add next
// using npm --save npm i next --save
Then we must install React because next.js makes use of React. The first line beneath makes use of Yarn for the setup.
yarn add react react-dom
npm i react react-dom --save
Two necessary folders pages and static must be created, otherwise next.js won’t work.
mkdir pages static
next.js-app -pages -static -package.json
After this execute “npm next dev” and open “http://localhost:4000/” on the browser.
So after all this, we have to create a homepage and index.js(entry point).
touch index.js home.js
And you can code your React component for which next.js is used. Next.js has a live reload function. All you want to do is simply trade and store, and next.js will collect and reload the app mechanically for you.
Another way is using create-next-app CLI
npx create-next-app my-app
Main aspects which help next.js perform!
Next.js performs server-facet rendering via default. This makes your application optimized. also, you can combine any middleware along with express.js or Node.js, and you may run any database together with MongoDB or MySQL.
Speaking of SEO, next.js comes with a Head thing that allows you to add and make dynamic meta tags. It’s my favorite feature — you could make custom and dynamic meta tags. those make your website able to be listed through engines like google.

This is some other one of the notable capabilities of next.js. when you operate the create-react app, you commonly need to install react-router and create its custom configuration.
next.js comes with its personal routers with zero configs. You don’t need any extra configuration of your routers. Just create your web page within the pages folder and next.js will take care of all routing configurations.
Lazy loading makes your software deliver a better user revel in. now and again the web page might take time to load. The person can also abandon your app if the loading takes extra than 30 seconds.
The way to avoid that is to use some trick to indicate to the consumer that the page is loading, for an instance by means of displaying a spinner. Lazy loading or code splitting is one of the capabilities that allow you to deal with, and control, slow loading so you only load the necessary code on your page.
