What’s so great about React Web Development?

React is the number one front-end framework worldwide. It has over 1500 contributors, more than 5.000 ready-to-use React components and millions of downloads every week.


React was created by Jordan Walke, a software engineer at Facebook in 2012. Just a year later it was open-sourced and has been under massive development ever since supported by an enormous and highly active community worldwide.

 

What makes React Web Development so unique? First of all, it’s designed for scaling. The component architecture allows developers to write the code once, and then re-use it in all their applications. There is a vast community-driven component library online. React developers love the approach of reusability. From the business perspective, it saves a massive amount of time and lets you and the React team concentrate on the specific challenges of your project. It is a massive treat for every React development company.

Why React is a great pick for web development

Advantage of ReactJS

  • ReactJS is quite easy to learn and use. It comes with a good set of documentation, tutorials, and training resources.
  • Building a dynamic web app specifically with HTML strings was tricky because it required complex coding, but React JS solved that problem and made it easier. Now, it provides less code and more functionality.
  • A ReactJS web app consists of multiple components, and each component has its own logic and controls. These React components are responsible for outputting a small, reusable piece of HTML code that can be reused wherever you need it.
  • ReactJS improves performance through the virtual DOM.
  • ReactJS has also gained popularity due to its handy set of tools. These tools make the developer's task clear and simple.

Disadvantage of ReactJS

  • React technologies are updating and accelerating so quickly that there is no time to do proper documentation. To overcome this, developers write instructions themselves as new releases and tools become available in their current projects.
  • ReactJS only covers the app's UI layers and nothing else.

As a marketplace providing top React engineers, we love great React-based projects. Today we present to you 20 stories of amazing React Web Development. Please, enjoy!

1. Facebook – React Web Development creators

Facebook has to be presented here for a very obvious reason. As mentioned above, it was created by one of their software engineers and since then it makes its way to Facebook’s front end.

 

In terms of code, Facebook is massive. Its codebase includes over 20,000 components, and, although it is heavily based on React, its tech stack is much more complex. Not to list every technology, they also utilize PHP and Python (namely: Tornado framework). React is used not only on the web version of the platform. It is also a base of other FB products, such as Whatsapp and Instagram (description below).

 

Due to its component architecture, it allows notifications, comments and post reactions to be displayed in real-time without the need of reloading the page. Same goes for the News Feed – new posts can appear there live.

 

2. Instagram – React for obvious reasons

When Instagram was acquired by Facebook in 2012 it didn’t have the web version of the app. But it was obvious that they had to create one. The library chosen was, no surprises there, React.

 

Since the very beginning of the web version of Instagram is 100% based on the React library. There are several cool features within the web version of Instagram that are made possible thanks to React. One example is Geoshare which allows viewing photos in real-time on a world map. Others are a live hashtag counter or Localgram which helps to find photos that people post around every given location.

 

3. Asana – project management made easy with React

Asana is one of the best project management tools out there. It’s a web and mobile application designed to help teams organize, track, and manage their work. Asana is experiencing constant growth since its launch in 2008. As for 2021, it has over 82,000 paying customers worldwide and recently raised 75 M $ in Series D round of funding. Among their customers, you’ll find star companies like Spotify, Uber, Autodesk or Trivago.

 

Asana web application was initially based on Luna, but with the growth of the product, a bunch of problems appeared – mostly with scaling up. That’s why they decided to rewrite the front end and chose React to do that.

There were solid reasons behind that: React is similar to Luna Views and it was fairly easy to integrate. Moreover, virtual DOM implementation helped to solve a lot of UI problems for us regarding focus and animation.

Incorporating functional purity in every component (…) has allowed us to develop large parts of our application in React while maintaining simplicity and performance.

Eric Pelz, Engineering Manager @ Asana

 

4. Khan Academy – educating the world with React

Reviewing huge chunks of material for an exam, trying to finally figure how math works, wishing to learn history from A to Z. However you wish to educate yourself, you can find all the resources to do so on Khan Academy, a platform that proves high-quality learning materials can really be free.

 

Khan Academy was established as a non-profit organization back in 2008 by Salman Khan, an educator, and mathematician who wanted to make sure kids around the world get the free help they need when it comes to studying. After over 10 years of Khan Academy’s existence, the online platform is now available in multiple languages and offers courses on such various subjects as math, physics, economics, and humanities. Each course is filled with professional videos explaining the topic and proper exercises.

 

The engineers at Khan Academy are using all the great features of both React components as well as React Native, the framework dedicated to mobile app development. The latter allows them to efficiently update their mobile apps for iOS and Android. To learn more about how Khan Academy uses React, it’s also worth checking its engineers’ special, regularly updated blog.

 

5. Codecademy – benefits of experimenting with React

Codecademy is an online freemium interactive platform that offers free coding classes. It is one of the most popular educational platforms for future web developers and mobile app developers. Over 45 million people trusted Codecademy with their professional growth.

 

Codecademy dev team is extremely happy with its React web development. Because it is component-based they were able to test individual pieces of the UI in isolation without interfering with the rest of the app. The possibility of serving a mostly-complete page to search engines significantly improved their SEO.

Furthermore, due to React compatibility with the legacy code, they were able to experiment with adding consecutive parts to the existing codebase. Bonnie Eisenman, Software Engineer from Codeacademy recommends experimenting with React in order to check how it might fit in with your code.

React is a lightweight, powerful, battle-tested library for building user interfaces with JavaScript. It’s not a full framework, but rather a powerful tool that may well change the way you approach front-end development. We’ve found it to be an incredibly useful tool for our front-end development, and we’re very happy with our choice.

6. Yahoo! Mail – from Web 1.0 app to React

Yahoo! Mailing app came a looooong way. Created in 1999 with C++ and HTML it was evolving through Java and PHP to end with React and NodeJS in 2015.

At this point in time Yahoo! Mail service was in deep need of changes. They had to implement predictable flow which would allow easy debugging, more up-to-date codebase, and independently deployable components.

 

Before they decided to go with React, Yahoo! Team considered Angular JS and Ember JS, but they were lacking the flexibility Yahoo! needed.

 

Finally, they decided to rewrite the architecture of the service with React components and Flux. There were several reasons behind this decision, such as one-way reactive data flow and Virtual DOM which allows the client and server-side rendering. They also underlined the importance of the growing community around React.

 

7. New York Times – simplifying the stack with React

The presence of React in the New York Times technology stack should be credited to their current CTO, Nick Rockwell. When he joined the NYT he faced the very diversified stack that he had put in order.

Boy, did they take advantage of this freedom. Go, Scala, Hadoop, Redshift, Dynamo, SQS, and many others all had a moment in the sun, with marginal planning around permanence or scale. Physical infrastructure was also scattered.

Nick Rockwell, CTO @ The New York Times

 

Rockwell and his team simplified the stack. Now they use a combination of React, Node, and GraphQL which provides the New York Times with a more stable front end. This is quite a change from PHP loading HTML and JavaScript library.

React seems to be working pretty well for the New York Times. Eventually, the entire online universum of the New York Times will be re-designed with React.

 

8. Atlassian – React & Software Development tools

Atlassian is an Australian enterprise software company that creates products for software developers and project management. If you are a software development agency or a software house you probably use their products. Tools like JIRA and Confluence are in their portfolio.

 

Atlassian is truly a React company as they use React internally and externally. They benefit from many React features, such as deployability to the Web, mobile, and desktop which allows developers to reuse libraries between platforms.

If the software is eating the world, then JavaScript is eating software, and React is eating JavaScript. In this food chain, it seems React has a big part of our future.

Travis Smith, Developer Evangelist @ Atlassian

 

9. PayPal – React-powered online payments

Although there are more and more ways of paying online and e-banking is growing, PayPal, often called the industry’s pioneer, is still doing well. By the end of 2021, there were 400 million active user accounts and 23 million merchant accounts on PayPal. The company’s revenue is also constantly increasing. In 2021, PayPal earned $1.11 per share, up 4% from a year earlier. The company said revenue rose 13% to $6.18 billion, including its acquisition of Honey Science.

 

Analysts had expected PayPal earnings of $1.07 a share on revenue of  6.23 billion. A year earlier, PayPal earned $1.07 a share on sales of $5.46 billion.

 

To support this growth and make sure the users are given a platform that meets all their needs and requirements, PayPal regularly updates its tech stack making sure the engineering team is using all the latest technologies on the market. Because of this, in 2015, the developers at PayPal started to implement React in their ecosystem.

 

As the engineering team wrote on their Medium blog:

Earlier this year, we started using react in our various apps at PayPal. For existing apps, the plans were to bring react in incrementally for new features and start migrating portions of the existing functionality into a pure react solve. Regardless, most implementations were purely client-side driven. But most recently, in one of the apps that we had to start from scratch, we decided to take a step forward and use react end to end. 

Currently, React is one of the most important elements of PayPal’s tech stack, making the company an incredibly important user of this technology.

 

 

10. Netflix - film viewing with React

The React version also works with Netflix - especially on their platform called Gibbon, which is used for low-cost TV devices instead of the DOM used in web browsers. Netflix even posted an official blog post explaining how the React library can help improve startup speed, performance, modularity, and other benefits.

 

Netflix's UI engineers told the following:

 

A number of factors influenced our decision to adopt React, primarily: 1) launch speed, 2) runtime performance, and 3) modularity.

 

Netflix UI engineers have embarked on several ambitious projects to revolutionize the user experience on desktop and mobile platforms. With the UI redesign at a scale similar to that of TVs and game consoles, it was important for them to reevaluate the existing UI technology stack and determine whether new solutions should be investigated.

 

11. Uber - React for transportation needs

Obviously, Uber devs are React fans. Just look at the Uber website: with a total of 79 million visitors ranking first in the ground transportation rankings, this website should provide the highest quality user experience. React plays an important role here.

 

The Uber engineering team has used the power of React since the site was built. With it, the team has created many open source libraries (you can use them for your project!). Most impressive are the map rendering tools.

 

In addition, Team Uber has created Base Web, a design system that provides reusable components for user interface development. It is built on top of React and allows you to create device-agnostic user interfaces. The team says reliability, availability, and customization are key characteristics and encourage the use of the system in any web project.

 

12. Airbnb - React-powered world-known vacation rentals platform

This world-famous vacation rental platform also uses React in its front-end. Have you ever noticed how quickly and how well web page elements load onto the screen? Splitting into several blocks, the content is updated organically, without delays or flaws.

 

Leland Richardson, an Airbnb engineer, describes the benefits of React in two simple phrases:

  • “Reusability/portability: React components are extremely reusable
  • Refactorability: React tends to make your code very easy to refactor and iterate on.”

 

 

 

 

Airbnb hasn't used React for a long time. But the choice was right: the platform grows and expands, and at the same time, React does not stop improving. Each new version provides convenient features to update and serve the huge P2P marketplace like Airbnb.

 

Meanwhile, Airbnb engineers are contributing to the React ecosystem. For example, they provided a useful React Sketch.app library for the needs of developers and designers.

 

13. Outlook.com - mail service utilized React potential

And here's another market leader who leveraged the potential of React in their web software product. In 2017, Microsoft introduced Microsoft Outlook, a personal information management tool. It includes email, calendar, contacts, and task components. The product is available in web and mobile versions. Here we pay special attention to the site.

 

In a blog post, Microsoft informs us about

 

"… introducing a more flexible web development environment that provides a refreshed search experience, a fresher look with a modern communication style, and a new design that lets you view, read, and attach files and photos faster."

Guess what framework they are talking about? Yes, this is React.

 

14. Dropbox - from CoffeeScript to React

Dropbox, a file hosting service, tells a different story. Their case is about a successful but challenging transition from CoffeeScript to a winning combination of Typescript and React.

 

Back in 2012, the decision was a mess. Numerous software engineers have contributed to the codebase. However, only a few of them were aware of what was happening on the site. The team chose the Typescript language and later, in 2016, started a redesign with the React library. Built with React and Typescript, the website has achieved great results.

 

Have you ever noticed how quickly you can access a preview of any document in Dropbox? By collecting the file data, React analyzes the page count and page size, builds a skeleton, and renders a preview as the user scrolls down the page. The Dropbox team used a combination of React JS, other JS tools, and several optimization techniques to create a

"smooth experience across all supported browsers."

 

15. Trello - migration from Backbone JS framework and Coffeescript to React

For nearly ten years, the web-based task management system has been powered by Backbone JS and Coffeescript. Back in 2009, it was a relatively powerful technology stack. But time flies, and so does the JavaScript library. Therefore, the team decided to move to a more dynamic stack.

 

The development team faced two major challenges.

  • The Backbone JS architecture was difficult to maintain + limited Trello's capabilities;
  • The caching procedure was incomprehensible and difficult to follow.

React and Typescript have been chosen as the primary tools for dealing with rebellion-related problems. Later, GraphQL joined the team. 

 

As a result, we can enjoy the ease of use of the Trello website, its well-designed components, and its fantastic responsiveness.

 

 

16. UberEats - a revolution in the restaurant business

Most people probably know this brand, but perhaps not everyone knows that viewing, ordering, and tracking orders is a result of using React.js.

 

Thanks to it, the restaurant's dashboard was developed, which can be accessed from smartphones or tablets. The UberEats team decided to partner with a React team.

“Restaurants need a way to communicate with both delivery-partners and eaters. At a bare minimum, the parties need to relay the:

  • Placement of a new order
  • Acceptance of an order
  • Arrival of a delivery-partner
  • Completion of an order

These four basic demands gave rise to the Restaurant Dashboard, a React/Flux single-page web application accessed through tablet devices.” 

Chris Lewis, a software engineer on the Uber Eats Prediction team.

17. Reddit - built in React from the ground up

Reddit is a worldwide online platform very popular in the US. It offers a unified forum gathering environment where users can discuss, comment, and share their own content/opinions. The portal is used by over 300 million users.

 

Reddit has used various ReactJS components in their framework build, and their team has evaluated various React features that have proven fruitful for them.

18. BBC - delivering news at a new level

A longtime favorite of many, a completely trustworthy source for millions, the BBC was a pioneer in the media industry. BBC business owners have a great responsibility to show only reliable and credible news in their online forum. And this is one of the main reasons why React development was chosen as the main technology for showing their news on the Internet. 

 

The BBC working group could realize the potential of React and the extent to which it can support its online version with the least amount of effort and downtime.

“On the front end we have embraced new technologies such as isomorphic Javascript using ReactJS. This allows us to execute our Javascript templates on both the server and the client meaning that users without Javascript can still load a basic version of the page. The technology will also allow us to quickly develop modules that can periodically update themselves with live data from around the BBC.”

Andrew Hillel, Senior Web Developer 

19. GitHub - unleashed potential of the service with React

GitHub is the world's leading software development platform that brings together a huge developer community to develop and build better software. It ranges from open source capabilities to business functions; GitHub is competent enough to manage projects on its periphery.

 

GitHub, being an important and valuable portal, has aimed to use ReactJS in its own development environment. The GitHub developers have fully trusted in the merits of ReactJS and unleashed its potential.

20. Zendesk - React-backed success in keeping customers interactions effective

The right company when it comes to keeping your customer interactions happy, simple, and effective.

 

Zendesk is a software organization that offers a SaaS-based package with features like issue tracking and monitoring, helpdesk management, and customer support.

 

Various Zendesk components have been built using ReactJS libraries and framework. Zendesk has a Garden design system that uses React components and utilities to render, localize, and navigate using the keyboard.

 

This list is not limited to numbers, there are many more organizations/applications that are reaping the benefits of this amazing technology - ReactJS.

A short memo for managers

So you decided to hire a dedicated React team, but is it the right approach for your particular project? Let’s delve together!

What React is the best fit for

Of course, we can't cover all ReactJS use cases in one article. The list is endless, but here are some examples of web applications where you can use ReactJS:

  • Dashboards or data visualization tools
  • Social networks
  • Ecommerce or retail
  • Blogs (Gatsby)
  • Business Websites
  • Portfolio
  • Forums
  • Sites rating
  • Membership Sites
  • E-learning modules
  • Galleries
  • Personal websites for self-promotion
  • Job boards
  • Business directories
  • Q&A sites like Quora
  • Non-profit donation sites
  • Wikis and knowledge bases
  • Mediacentric sites like YouTube
  • Auction and coupon sites

Talent pool

Approximately 8,787 industry leaders are currently using React. js; some of the most powerful are Airbnb, Uber, Netflix, Instagram, WhatsApp, BBC, Twitter, and Reddit. Since its release in 2013, the React community has grown to 56162 people.

 

Overall, React is a quite popular and easy-to-use language. Therefore, it wouldn’t be a struggle for you to find a guy who knows how to code. Another deal is to find the one who has a decent proficiency and can offer some guarantees. So be sure to hire devs only via vetted platforms.

React’s future

React JS isn't going anywhere. According to Stack Overflow, it is the number 1 web framework used by software developers around the world. In this way, React is far superior to its competitors like jQuery or Vue.

 

This trend is noticeable not only in the United States but even in developing countries such as India. A recent report shows that open positions of React JS programmers have increased by 184% since COVID.

 

Thus, we can say that React will dominate the future for many years on a global scale.

 

Plus, React is still a living technology. Facebook is responsible for updating the tool to offer better features and functionality.

 

This will be a game-changer even in the future. JavaScript developers will be able to use React to create innovative products. Companies will continue to hire JavaScript developers, but React programmers will take over. You can look forward to bright days ahead and hope to capitalize on your React product with no exceptions.

Wrap-up

Reactjs is a great addition to projects that require component reusability, impressive user experience, or crazy animations. However, it is a robust user interface library for building projects targeting small, medium, and even large organizations. This is why so many companies rely heavily on React to achieve their long-term business goals. In this article, we have detailed the Reactjs use case. Be sure to write down these use cases and features before you decide to use them in your project.
