The first step was the creation of FaxJS. The need for a library like React was born as Facebook Ads were getting bigger popularity. It became hard to manage, so Facebook needed to come up with a good solution for it. The number of features increased, the number of engineers working on the product also and the code base grew bigger. That slowed them down as a company. Over time it became difficult to handle, as they faced a lot of cascading updates.
Facebook engineers couldn’t deal with that problem easily. Their code demanded an urgent upgrade to become more efficient. That’s resulted in Jordan Walke building a prototype that made the process more efficient, and this marks the birth of React.js. The rules behind the idea were simple:
Seamless Client-Server Rendering
Write once, render anywhere - client or server
Views are automatically updated on state changes - no bindings necessary
Fast rendering using string concatenation, small code size
High-level components, functionally defined, declarative views
As the works on the prototype were progressing quickly, it soon became what we know today as React. Its first use case was Facebook newsfeed in 2011. As the story goes on in 2012 Instagram was acquired by Facebook. Their Instagram team wanted to adopt Facebook’s new technology in their project too. At the same time Mark Zuckerberg wanted to increase the number of consumed feed stories and by that get more profits from monetization.
To do that he decided to change strategies. In the case of mobile, he admitted that the mobile strategy relied too much on HTML5, rather than native applications. As he said, “We’re going to execute this mission to make the world connected and build value over the long-term. The bigger question that will define how we’ve done is how we do with mobile.”. That’s also the moment when he admitted that for Facebook mobile is everything, and it will surpass desktop as far as future ad revenue.
React gets open-sourced
With time, React grew, and Facebook decided to make it open source. The decision was announced in May 2013 at JSConf US. It’s worth mentioning that at the beginning the audience was skeptical. Most people thought that React in reality was a huge step backward. To be honest this was caused by the fact that most attendees of this conference were 'early adopters' when React targeted 'innovators.' The creators decided to start a 'React tour' to help to better understand the React concept.
Through the year React popularity was growing, the community did 2.3k commits and addressed 1.5k issues, version 1.0(0.1.0) was released with big names such as Khan Academy, New York Times, and Airbnb (and naturally, Facebook and Instagram) using React in production. In 2015 Netflix shared their use case of React, in the same year, the first preview of React Native was shown by Facebook on React.js Conf 2015.
React Native wasn‘t meant to be a “write once, run anywhere” tool, it was more a “learn once, write anywhere” tool. This ensured that the same set of engineers can build applications for whatever platform they choose, without having to change the syntax. The story of React Native is pretty fascinating. It started as Facebook’s internal hackathon project in the summer of 2013, since then it became one of the most popular frameworks. The first public preview was in January of 2015 at React.js Conf 2015, later Facebook decided to go open with React Native and announced that on F8.
After a year, React Native’s growth and adoption were visible. The statistics on the Github repository were at this time quite impressive. More than 1000 contributors committed around 8000 times in 45 branches with 124 releases. React Native was the 14th most starred repository on GitHub. In 2016 Facebook announced that React Native will get backing from Microsoft and Samsung by bringing it to Windows 10 and Tizen. It’s not a surprise that React became so popular with the support of technical giants and a dedicated community.
React provides advantages like declarative rendering, top-down data flow, encapsulated components, and many others, which may be the reason why it’s so widely adopted nowadays. React helps developers with making scalable and modern applications that look and feel like native apps. React did not only have an impact on the way how we write apps, but it also influenced how we design them.
It allows developers to create large web applications that can change data, without reloading the page. That’s the big game-changer in the case of user experience. The main purpose of React is to be fast, scalable, and simple.
