Why doesn't GitHub use react js?


React.js is an open-source JavaScript library developed by Facebook that makes it easy to build user interfaces and manage state in complex applications. It combines HTML with JavaScript to create reusable components that can be used separately or together. React.js enables developers to write code that is organized, efficient, and highly performant, and allows them to update components without breaking the entire application.
GitHub is an online service that provides cloud storage for source code and version control. It allows developers to track changes to code over time, and provides collaboration tools for working on projects with other individuals or teams. It is closely associated with the open source software development model, although developers can use it to store any type of digital content.
React JS is a JavaScript library designed for building high-performance user interfaces and is one of the most popular libraries for creating web applications today. It is designed for creating reusable components that can be used together or independently. React JS simplifies the process of creating dynamic user interfaces and is well-suited for projects which require frequent changes or a great deal of interactive content.
The main reason why GitHub does not use React JS is that it is a heavy library, which can be difficult to integrate into an already existing application. Furthermore, React JS is meant for larger scale applications, and it requires additional investments and efforts to understand and implement. While GitHub is a fantastic development platform for open-source projects, it is still a platform for primarily creating web applications in JavaScript, HTML and CSS, without additional libraries.

Reasons Why GitHub Rejects React JS

Reasons Why GitHub avoide React JS

React JS is one of the most popular JavaScript frameworks for developing user interface applications. It’s used by developers across the world to create web and mobile applications. Recently, though, GitHub has moved away from using React to developing applications. There are several potential reasons why they don’t use it anymore.
The first reason may be performance. React is a mature tool and works well, but often it takes longer to load than other technologies. This can cause pages to load slowly, leading to a negative user experience. This poses a challenge for GitHub, as their users expect pages to load quickly on the platform.
Another potential reason may be complexity. React allows developers to incorporate many features and customizations across an application. But for GitHub, it can be difficult managing complex interface components, as developers would need to constantly tweak and maintain the application in order to keep up with user expectations.
The last possible reason could be scalability. React is a great solution for applications with a handful of features or components but may not always be the most ideal for expanding applications that have to scale. Managing complex features across a growing application can be a challenge, and GitHub may not have the resources to make sure the framework remains stable and reliable.

Alternate Uses for GitHub

With React no longer being the main technology of choice for creating applications on GitHub, what other options are they exploring? Here are several possible alternatives:

  • Node.js – Node provides fast, secure, and reliable performance. It can also be used to build back-end systems with databases like MySQL and MongoDB.
  • GraphQL – GraphQL is an open-source query language for APIs. It helps developers build dynamic applications by allowing them to query multiple databases with fewer requests.
  • Angular – Angular is a popular choice for building complex, interactive web applications. It is used by many development teams and has many built-in features.
  • Vue.js – Vue.js is a JavaScript framework created for rapid development. It’s versatile and provides a robust development environment.

As GitHub continues to evolve and adapt to the needs of its users, it’s likely that the company will continue to rely on these and other technologies to create powerful applications. There is also the possibility for them to develop their own unique solutions that are tailored to their specific needs.

Exploring Alternative Options for GitHub

How Not Harnessing the Power of React Impairs GitHub

One question that continues to recur amongst tech aficionados inquiring into GitHub’s lack of React JS is “Does its absence impede their ability to provide users with appealing web applications?” The answer is a resounding yes. React JS is one of the most popular JavaScript libraries to date, offering its users an array of useful tools including its Virtual-DOM. This gives React the ability to quickly determine what changed on the page and when, and then ensure that our updates are as fast and efficient as possible. Not taking advantage of this library has proven to be a strategic misstep on GitHub’s part, hampering their ability to offer the most user-friendly experience possible.

What Is the Root of this Problem?

Digging deeper, what exactly is behind the lack of React existence on GitHub’s platform? Various theories have been advanced, but it comes down to one simple answer: time. Basic economics are in play here; the cost of a feature is what it takes to build, or in this case, incorporate. React has a high learning curve and the time it takes to get up to speed with it can be intimidating for a company with limited resources. Moreover, the environment it works with, and the technical challenges necessary to bridge the gaps, are huge obstacles that have so far prevented GitHub from introducing React.

The Best Practices to Implement React in the Future

In the present day world, time is money, and as such being able to efficiently develop and introduce new technologies onto a platform is a must. With that in mind, utilizing React in the future would be a great idea, not only to increase the appeal and user friendliness of GitHub’s web applications, but to also reduce the time it takes to build and deliver solutions to users. Having developers willing to invest the time to read and code with React, and to bridge the gap between the two platforms would be immensely useful; in fact, it’s been done before and in the developer community as well. However, it seems that GitHub’s development team has decided to take the slow and steady route instead.

Advantages of Not Using React JS for GitHub

GitHub’s Unfortunate Lost Opportunity

Many web developers are familiar with React js, a JavaScript library that simplifies the creation of dynamic user interfaces. GitHub, which provides a range of tools to facilitate the development and collaboration on software projects, offers features that allow developers to use code primarily written in JavaScript to build projects. While GitHub has plenty of available features, its decision not to use React js keeps it from having maximum productive potential.

Why React May Be the Better Choice

The main benefit of using React js is that it simplifies the development of user interfaces. React allows developers to easily create components and have them all work together seamlessly. This makes it much easier for developers to make changes across an interface in a cohesive manner. This makes the development process much more efficient, as developers can quickly make changes to fix bugs or update the UI.
Interestingly, the React js library also contains all of the features of numerous other JavaScript libraries, such as AngularJS and jQuery. This means that, if developers were to choose to use React, they could use the same library for all interfaces, eliminating the need to remember different syntaxes for different libraries. With GitHub not using React, developers are missing out on this added convenience.

The Downside to React

Despite the benefits of React js, there are some drawbacks that could be deterring GitHub from utilizing it. React makes use of a virtual DOM, which requires extra computational overhead. This could make web applications written in React slower than those written in other JS libraries, particularly with applications that have complex data handling. Additionally, React can be more difficult to learn as the syntax can be less intuitive than that of other popular libraries.
Lastly, React is a library that relies on third-party components, and provides only limited styling capabilities on its own. This means that developers must incorporate other packages into their projects to add styling and additional features. When these packages are added, it can be harder to debug projects if something goes wrong. With GitHub not using React, developers can avoid dealing with the complexities of these packages.
These potential draw-backs could be why GitHub has chosen not to use React js. With GitHub’s decision not to use React, developers are being deprived of the simplified interface that the library provides. This could mean a longer development time and a greater risk of errors. Why not take the risk and try to maximize the potential of GitHub by using React js?


The importance of staying up-to-date with technology advancements in this digital age cannot be overstated. With the rapid changes in the tech industry, many organizations are now looking towards React JS as a reliable and efficient platform to streamline operations. So why then has GitHub refused to utilize this versatile programming language?
As with most things in the constantly-evolving tech world, an answer to this seemingly one-sided question is far more complex than a simple yes-or-no. While the actual motivations behind this decision may remain a mystery, what is certain is that GitHub takes the security of its user base extremely seriously. It is likely that the software giant has weighed the advantages and disadvantages of utilizing React JS for their projects and decided that, at this moment in time, it would not be the best approach.
It is fascinating to contemplate the underlying reasons behind this decision, but only time will tell if it was the prudent choice. For now, all one can do is keep an eye on the blog posts and releases put out by the company to see if anything changes. In the meantime, it might be worthwhile to explore React JS for yourself and see what all the fuss is about. After all, knowledge is power in the tech industry and that is why staying on top of the latest trends is so important.
