The series will cover these features in detail, and prerequisites include a solid understanding of HTML, CSS, JavaScript, ES6+ features, and React fundamentals.

Keywords

💡Next.js

Next.js is a React framework designed for building web applications. It extends the capabilities of React by providing additional features such as routing, data fetching, and server-side rendering. In the video, Next.js is introduced as a framework that simplifies the process of building production-ready web applications, emphasizing its ability to handle more than just the view layer, unlike React alone.

💡React

React is a JavaScript library for building user interfaces, primarily used for the view layer of web applications. It is the foundation upon which Next.js is built. The video mentions that Next.js uses React for building user interfaces and that having a good understanding of React fundamentals is essential for working with Next.js.

💡Routing

Routing refers to the process of determining how an application responds to a client's request to a specific endpoint. Next.js offers file-based routing, which simplifies the creation of routes without the need for third-party routing packages. This is highlighted in the video as a key feature that differentiates Next.js from plain React applications.

💡API Routes

API Routes in Next.js allow developers to create server-side APIs that can be called by the React app. This feature makes Next.js a full-stack framework, as it enables developers to write both the front-end code in React and the back-end APIs. The video script mentions this as a noteworthy feature that might surprise viewers.

💡Rendering

Rendering in the context of web development refers to the process of generating the final HTML sent to the browser. Next.js supports both server-side and client-side rendering, which can lead to better performance and SEO. The video emphasizes the importance of rendering for creating a production-ready application.

💡Data Fetching

Data fetching is the process of retrieving data from a server to display in a web application. Next.js simplifies data fetching with support for async functions in React components. The video script uses data fetching as an example of how Next.js helps developers by providing built-in solutions for common tasks.

💡Styling

Styling in web development pertains to the visual presentation of a website. Next.js supports various styling methods, including CSS modules, Tailwind CSS, and CSS-in-JS. The video mentions this to illustrate how Next.js accommodates different developer preferences and practices for styling web applications.

💡Optimization

Optimization in web development involves improving the performance and efficiency of a website. Next.js provides optimizations for images, fonts, and scripts out of the box, which contributes to better core web vitals and user experience. The video script highlights optimization as a key feature that makes Next.js an attractive choice for developers.

💡Development and Production Build System

A development and production build system refers to the tools and processes used to compile and prepare web applications for deployment. Next.js offers a well-optimized build system that allows developers to focus on coding rather than configuration. The video emphasizes this as a feature that streamlines the development process.

💡ES6

ES6, also known as ECMAScript 2015, is a version of the JavaScript language that introduced several new features and syntax improvements. The video script mentions that viewers should be familiar with ES6+ features, indicating that modern JavaScript concepts are necessary for working effectively with Next.js.

💡Prerequisites

Prerequisites are the necessary skills or knowledge required before starting a particular task. In the context of the video, prerequisites refer to the foundational understanding of HTML, CSS, JavaScript, and React that is needed to effectively learn and use Next.js.

Transcripts

hey everyone my name is vishwas and

welcome to a brand new series on next

year for beginners in this series we

will start from scratch and learn the

different concepts in next year

specifically we will focus on next

year's version 14 or above depending on

when you're watching in this

introductory video I will briefly talk

about what next year is why you might

want to learn it and the prerequisites

to get

started let's begin with what is

next next sh is a react framework for

building web

applications when building applications

with react alone it's not feasible to

create a fully featured application

ready for

production react is a library for

building user interfaces responsible

only for the view layer of an

application as a developer you need to

make decisions about other features such

as routing data fetching and

more next sh on the other hand is a

react framework it uses react for

building user interfaces but also

provides additional features that enable

you to build production ready

applications these features include

routing optimized rendering data

fetching bundling compiling and more you

don't need to install additional

packages as Niar provides everything you

need however keep in mind that nexs

being a framework has opinions and

conventions that should be followed to

Implement these features there is no

need to worry though as the conventions

have emerged from a team with years of

experience in writing react applications

for

production to reiterate nexs is a react

framework for building production ready

applications for the

web now that we know what NS is let's

see why you might want to learn it the

reason to learn next Shar stems from the

fact that it simplifies the process proc

of building a web application for

production let me list some of the

noteworthy features that nxs provides

out of the box the first one is routing

when building a react app you need to

install a thirdparty routing package

configure it and add code every time you

need to create a route nextjs offers

file based routing simplifying the task

of creating routes and eliminating the

need for thirdparty routing

packages the second feature is a Epi

routes and this might come as a surprise

to many of you however nexts allows you

to create epis making it a truly full

stack framework with NEX you can write

both the front end code in react and the

apis that can be called by the react

app the third feature is rendering nexts

supports both server side and client

side rendering when used correctly it

can result in better performance and SEO

which is something we all

want the fourth feature is data fetching

nexts offers simplified data fetching

with async AWA support in react

components nexts also supports your

preferred styling methods including CSS

modules tailin CSS and CSS injs ljs also

provides optimization out of the box for

images fonts and scripts to improve your

applications core web vitals and user

experience last but not least nexts

provides a well optimized development

and production build system allowing you

to focus on coding rather than

configuration the combination of these

features makes nexs an amazing framework

to work with throughout the series we

will learn these features in detail also

please note that I might refer to next

sh as just next in the series so please

don't get

confused to get started with next sh you

need to have a solid understanding of

each HTML CSS and JavaScript

fundamentals we will be using es6 plus

features so make sure you familiar with

modern JavaScript Concepts as

well since nexs is a react framework it

is essential to have a good

understanding of react

fundamentals you don't need to be an

expert but Concepts like function

components props State jsx and hooks are

required if you're new to react I have

an extensive tutorial series that covers

react from beginner to Advanced levels

so make sure to check that out my goal

is to guide you from a complete beginner

to becoming an expert in next year all

the source code related to this series

can be found in my GitHub repository

which is linked in the video

description with this introduction let's

start with a simple hello world

application in the next video thank you
