Hi, hope you are doing well. In this article we will learn about 5 disadvantages of ReactJs. So, without wasting any time. Let's get started!

1. Client-Side Rendering:

It is one of the core features of ReactJs i.e. it supports the rendering process on the client-side. Earlier when a client sends a request to the server, the HTML page was rendered on the server and after that, it was served to the client. This increases the load on the server specially when the application size was big & requires continuous interaction. So, React team thought that we could render the application on the client-side which will remove the overhead on the server and will eventually save the resources. It increases the load on the client-side. Plus it takes some initial time to load the application because the server is sending the whole application's files at once. There could be an argument here that it is a drawback or a feature.

2. Lack of SEO:

Although the React applications are very fast and optimized for performance but it has serious SEO (Search Engine Optimization) related issues. As we know that out of the box React uses client-side rendering but at the current date, web crawlers do not understand javascript rendering. Search engines especially Google claim that their crawlers understand javascript rendering but the truth is that they do not understand it. This could be a huge loss for businesses because every business wants to get their presence on the search results. Search traffic is one of the most important sources of potential customers.

3. Routing is Unavailable:

ReactJs is so elegant, simple & good at the performance that developers expect that routing should be present within it out of the box. Unfortunately, we need to install an extra npm package called react-router-dom to handle the routing. Routing is available in Angular and Vue right out of the box.

4. Form Validation & Handling:

The inbuilt feature of handling form validation and handling is not present in ReactJs as it is available in Angular. For form validations, we need to download extra tools like Formik. Otherwise, we need to write form validations manually.

5. State Management:

In earlier versions of React state management was unavailable. Developers need to install the Redux in their project for state management. Now, this problem is solved through Context API but there is an issue with it. It does not handle the State effectively when the application and state become larger. For this purpose developers needs to rely on Redux or another state management libraries. Although, Context API is a great tool for managing states.

The good news for you is that Vercel has launched a framework for ReactJs which is known as NextJs. By using NextJs we can now develop complex production-ready applications using Standard React without sacrificing the SEO. It provides us Server Side Rendering features, inbuilt File-Based Routing, image optimization features, and a lot more.

You could check more about NextJs from their official Documentation.

Thanks for giving your precious time. Goodbye!
