
NextJS is a **framework for ReactJS**.

Wait a second ... a "framework" for React? Isn't React itself already a framework for JavaScript?

Well ... first of all, React is a "library" for JavaScript. That seems to be important for some people.

Not for me, but still, there is a valid point: React already is a framework / library for JavaScript. So it's already an extra layer on top of JS.

## Why would we then need NextJS?

Because NextJS makes building React apps easier - especially React apps that should have server-side rendering (though it does way more than just take care of that).

In this article, we'll dive into the core concepts and features NextJS has to offer:

- File-based Routing
- Built-in Page Pre-rendering
- Rich Data Fetching Capabilities
- Image Optimization
- Much More

## File-based Routing

Getting Started with NextJS


For the past few years, Frontend developers have shown partiality towards **React**, with **Vue.js** and **Angular** tagging behind closely. However, regardless of who dominates the battle of most popular JavaScript frameworks, there are some next-generation reactive frameworks available. They may soon rise as the lean alternatives to these popular web app development framework ecosystems in 2021.

Let’s take a look at the most in-demand and promising front end development frameworks for your web development projects in 2021.

## 1. React

React makes it easy for developers to create interactive user interfaces. The framework is designed with backward compatibility and component-centric applications in mind, so you can be assured about the longevity of your application. 

One of its major advantages is the ability to use it for native development. Reusable components, better performance, support from Facebook, a large developer community, and SEO friendliness, are some of its added advantages.

When To Use React: Developing small enterprise-level appsCreating SPA or cross-platform applications

## 2. Angular

Angular is generally used to build front-end applications in both large enterprises and small-sized companies. However, its popularity has taken a dip in the past few years. 

Angular increases the performance of browser-based applications by dynamically updating the contents in no time since it uses two-way data binding. 

When To Choose Angular: Large scale applications, if you need a scalable architecture or prefer TypeScriptBuilding real-time applications. It supports many popular websites and web apps like Sony, PayPal, Upwork, and the Guardian.

## 3. Vue

One of the most popular front-end frameworks nowadays! Vue is a straightforward and simple framework. It’s good at removing the complexities that Angular developers face. It’s smaller in size and offers two major advantages – a visual DOM and a component-based approach in building user interfaces. It’s also a 2-way binding ecosystem that can handle both dynamic and simple processes with ease.

Why Choose Vue.js: Helps design everything from scratch and is successful in developing giant projects as wellAssists in multiple tasks Helps in building web applications, mobile apps, and progressive web applications
Vue is the framework behind Alibaba, 9gag, Reuters, Xiaomi.

## 4. Svelte.js

Svelte.js is an open-source, component-based frontend JavaScript framework written in Typescript. It is touted as a game-changing and revolutionary idea.

Svelte, unlike React or Vue, has no virtual DOM and does not require high browser processing. Instead, you build components boilerplate-free in simple JavaScript, CSS, and HTML code. 

Reasons to choose Svelte.js: Lightning-fast apps with excellent performance Zero client-side dependencies, and no need for complex state management librariesUsed by Godaddy, Razorpay, 1password, New York Times

## 5. Preact.js

Preact.js follows a component-based approach with Virtual Dom, the same as React – while being completely compatible with React. It can even use React packages without compromising on leaner size, performance, and speed. 

In cases where the full potential of React isn’t necessary, most developers even use React during development and switch to Preact for production. 

Reasons to choose Preact.js: Lightweight, swift, and high-performance librarySimply 3kb in size (minified and zipped) and yet gives you all the necessary functionality of ReactMany major companies like Lyft, Uber, and Tencent are using Preact

## Conclusion

Many companies hire a front-end development partner with extensive experience to maintain or extend your code. This carries considerable weight, especially with project managers.
