Developers will often opt to use ReactJS in combination with Node.js to build reusable user interface (UI) components. React is an open-source JavaScript library and it is often used as the V in MVC because it uses a JavaScript virtual DOM, which is faster than an ordinary DOM. This allows for a simpler programming model that offers better performance. Additionally, despite being designed to be used in a browser, React is also able to be rendered in a server using Node.js. ReactJS's data and component patterns also help maintain large applications and improve readability across devices.Node.js uses a single threaded model combined with event looping that makes for a highly scalable server different from traditional servers like the Apache HTTP Server which create limited threads to handle a large number of requests. This single threaded model also prevents the server from responding in a non-blocking manner, since there are practically no functions in Node.js that directly perform I/O. Additionally, because they output the data in bulks, applications created with Node.js do not suffer from buffering.Businesses looking to develop their own fast-running applications will benefit from a tag-team combination of Node.js and ReactJS. Not only will they enjoy having thousands of previously built, open-source libraries for Node.js, but they will also enjoy the efficiency of its simplified model plus the support from the Node.js and ReactJS developer community.

You may have picked up this book with some level of JavaScript knowledge. There is also a high probability that you have an idea of what React js is. This chapter highlights the key aspects of React as a framework, explains the problems it solves, and describes how you can utilize the features and the rest of the information contained in this book to better your web development practices and create complex, yet maintainable user interfaces using React.Defining React jsReact js is a JavaScript framework. React was originally created by engineers at Facebook to solve the challenges involved when developing complex user interfaces with datasets that change over time. This is not a trivial undertaking and must not only be maintainable, but also scalable to work at the scale of Facebook. React js was actually born in Facebook's ads organization, where they had been utilizing a traditional client-side Model-View-Controller approach. Applications such as these normally consist of two-way data binding along with rendering template. React changed the way that these applications were created by making some daring advances in web development. When React js was released in 2013, the web development community was both interested and seemingly disgusted by what React was doing. As you will discover throughout this book, React challenges conventions that have become the de-facto standards for JavaScript framework best practices. React does this by introducing many new paradigms and shifting the status quo of what it takes to create scalable and maintainable JavaScript applications and user interfaces. Along with the shift in front-end development mentality, React comes with a rich set of features that make composing a single-page application or user interface approachable for developers of many skill levels-from those who have just been introduced to JavaScript, to seasoned veterans of the web. You will see these features-such as the virtual DOM, JSX, and Flux concepts-as you read this book and discover how they can be used to create complex user interfaces.You will also see, in brief, how Facebook is continually challenging the development world with React Native. React Native is a new open source library for creating native user interfaces utilizing the same principles as React's JavaScript library. By creating a Native UI library, React has pushed its value proposition of "learn once, write anywhere." This paradigm shift applies to being able to utilize the core concepts of React in order to make maintainable interfaces. By now it is possible you are thinking that there is nothing React can't do when it comes to development. This is not the case, and in order to further understand what React is, you need an understanding of what React is not, which you learn later in this chapter. First, you will understand the underlying problems that caused React to be created and how React solves those problems.

React jsThe Complete Beginner's Guide to React - 2nd Edition (2020)Facebook's React has changed the way we think about web applications and user interface development. Due to its design, you can use it beyond web. A feature known as the Virtual DOM enables this.In this chapter we'll go through some of the basic ideas behind the library so you understand React a little better before moving on.What is React?React is a JavaScript library that forces you to think in terms of components. This model of thinking fits user interfaces well. Depending on your background it might feel alien at first. You will have to think very carefully about the concept of state and where it belongs.Because state management is a difficult problem, a variety of solutions have appeared. In this book, we'll start by managing state ourselves and then push it to a Flux implementation known as Alt. There are also implementations available for several other alternatives, such as Redux, MobX, and Cerebral.React is pragmatic in the sense that it contains a set of escape hatches. If the React model doesn't work for you, it is still possible to revert back to something lower level. For instance, there are hooks that can be used to wrap older logic that relies on the DOM. This breaks the abstraction and ties your code to a specific environment, but sometimes that's the pragmatic thing to do.One of the fundamental problems of programming is how to deal with state. Suppose you are developing a user interface and want to show the same data in multiple places. How do you make sure the data is consistent?Historically we have mixed the concerns of the DOM and state and tried to manage it there. React solves this problem in a different way. It introduced the concept of the Virtual DOM to the masses.Virtual DOM exists on top of the actual DOM, or some other render target. It solves the state manipulation problem in its own way. Whenever changes are made to it, it figures out the best way to batch the changes to the underlying DOM structure. It is able to propagate changes across its virtual tree as in the image above.Virtual DOM PerformanceHandling the DOM manipulation this way can lead to increased performance. Manipulating the DOM by hand tends to be inefficient and is hard to optimize. By leaving the problem of DOM manipulation to a good implementation, you can save a lot of time and effort.React allows you to tune performance further by implementing hooks to adjust the way the virtual tree is updated. Though this is often an optional step.The biggest cost of Virtual DOM is that the implementation makes React quite big. You can expect the bundle sizes of small applications to be around 150-200 kB minified, React included. gzipping will help, but it's still big.
