Vercel developed Next.js, which is a framework. It’s free and open-source, built on Node.js and Babel. The highlight? The framework works with React to create single-page apps. This makes rendering on the server a breeze, which is always a stress-free experience.
Next.js empowers static export and pre-rendering features, as well as several other useful functions. For example, some other top features include automatic building size optimization, improved developer assembly, and a preview feature.
Now that you know a bit of refreshing information on Next. js, we can move on to discussing what React is.
React, originally started by Facebook, is one of the most demanded front-end libraries today. It is one of the most common JavaScript frameworks. Recommended by developers, React should be utilized by using a “reactive strategy” and applicable programming.
You’ll need to develop your own React process. This is a more difficult road than simply adopting what other JavaScript frameworks provide: a plethora of ready-to-use capabilities.
Furthermore, React is characterized as a library (a utility that can be used in any project ) rather than a framework (a comprehensive architectural design).
Developer experience is generally considered while selecting a software library or framework. Developer “experience” refers to how developers are able to successfully finish a project and why they tend to flock towards frameworks that are enjoyable and easy to navigate.
For developers in the territory of React, Next. js has become a great demand for developers who need a framework that gets “to the point,” so Next. js is essentially built on top of React to make the development straightforward.
One of the key highlights of Next.js is that it is fast and clear. These days, we are impatient, so if you are looking at Next.js, it could benefit you in this way. With Next.js, automatic server renders and code splitting will consistently improve the performance of your application. So, if you care about performance, which I am sure everyone does, Next.js holds that title.
However, React is a leader in the talent pool. React is supported by Facebook, as stated previously. Front-end job prerequisites revolve around React. That fact, mixed with being created by Facebook, is deemed safe and reliable by users. In conclusion, it will be easier to find developers operating with React preferably than Next.js.
So, if React is deemed the most comfortable and safest. What are the disadvantages of using Next.js?  A handful of disadvantages include:
●     It is only restricted to a file router when in use.
●     You cannot change the way it works with routers.
●     You will need a Node.js server to use different routes.
The positives?
●     Next.js is fast. Apps that are created with Next.js are fast. This is all due to the static site creation and rendering.
●     Ability to use API routes.
●     You can deploy React applications.
●     Understandable and clear to arrange and add distinct plugins.
Now, what does that look like against React? Some of the positives in using React are the following:
●     React has multiple components that have their controls that represent reusable components in rendering.
●     Optimized for search engines
●     Improves performance
●     A convenient set of tools that enables clear and simple task completion.
●     Building complex web applications is a breeze
●     Many tutorials and documentation following the design of React. It’s all about taking your time and learning.
Although these are some great positives of React to look at, React isn’t always the best option for every project. Yes, it is powerful and is extremely helpful, but it doesn’t need to be applied to already simple applications. You can just complete those in javaScript without outsourcing.
Overall, React is a bit more versatile in its features, but Next.js is also a great addition as well. It all depends on what the developer is working on, what projects, and how these additions would help.
