Creating Quality Standards for React app? Here’s A Perfect Solution!

 In today’s business-centric world, it is an arduous task to pick the right app development framework for your business from the many available options. Choosing a correct platform seems more like choosing an asset for your brand where a mere negligence or a wrong step can cause negative results.

When I happened to encounter React for the very first time I remember seeing many different approaches when it was about building user interfaces. Being initially developed for JavaScript, React has revolutionized to a great extent by creating reusable components that offer your site a consistent look and feel. The flexible looking JavaScript comprises of an efficient front-end javascript library which is mainly used to build UI and is considered as the most in demand in the job markets in 2018.

Evolution of React

2011 was a crucial year for Facebook developers as they faced many issues with code maintenance. With the increasing popularity of the app, the team was required to expand to keep things running more perfectly. As the time passed, the app became more and more difficult to handle due to a lot of updates. As a result, their code demanded an urgent upgrade to become more efficient. The model was absolutely perfect but they required to do something about the user experience. A software engineer named Jordan Walke built an initial model that made the process more systematic, and this is how React.js came into being.

In simple words, React is considered to be the view ‘V’ in the Model View Controller (MVC) model. Views are basically those logic-less files that can be easily controlled by a controller. However, React does not replace the view, rather it makes it more modular by creating highly reusable components in regards to pop up modals, lists, sortable tables, etc.

One of the biggest reasons behind the making of React is to allow software developers to make their own elements which are pretty similar to HTML. A page is a collection of smaller pieces popularly known as components which are mainly used to create large web applications, which can change the displayed elements or data without the need to reload the page. Let’s take an example of Facebook likes. We all know the fact that the number of likes can increase or decrease without having to reload the page. Due to which it has become very easy for one to build modern, complex user interfaces.

How to Get the Best Out Of React?

Like I said before React has grown into one of the most popular tools found in a web developer’s library. Down below I would like to mention a few pointers through which React app developerscan improve their code output.

#1

Components in React often tend to share functionality with each other for example logging or network requests. These can be pretty much difficult to maintain at times do you know why? The number using this logic increases on the constant basis. So that, developers are encouraged to abstract shared code and include it where necessary.

Now if we take a look at a regular JavaScript application, the concept of a higher-order function is one way to approach it. This means they are functions that take other functions as arguments and impart behaviors onto them. Several types of methods such as map and filter can be considered as the best examples of these. If you have ever worked in React then I am sure you will know Higher-order components (HOCs) are React’s way of achieving the same thing.  By using HOCs, some of the most commonly used chunks of code becomes easier to maintain and test. When specific functionality is required, it becomes easy to drop in, safe in the knowledge that it will behave as expected.

#2

Here products are mainly fetched by an external method inside the container. They are held within its own store and then passed as props to the presentational component Products that display them. This component is such a kind that does not know how to display the information, it only knows how to fetch and adjust it. Likewise, the presentational component does not know where the data actually came from. Another interesting benefit of using such an approach is that it makes things easier to unit test. The container tests only need to worry about the state being set, while the presentational component can be passed static props to achieve a predictable outcome.

#3

Can you define the term ‘Render prop’? Coined by Michael Jackson, render prop was something which can easily replace higher-order component pattern. The basic idea was to pass a React component within a callable function as a property and call this function within the render function.

So, What else?

Do you think there is any other programming language that would be more compatible with React? Fortunately, there are:

Reason

Not being a new language, Reason can be considered as the best alternative to Javascript-like syntax and toolchain for OCaml. Those who don’t know, OCaml is a functional programming language that’s been around for more than 20 years. With its C-like syntax, Reason makes OCaml approachable for people coming from mainstream languages such as JavaScript or Java. In fact, it may quite interest you to know that it provides you with better kind of documentation and a growing community around. Integrating with your existing JavaScript codebase can be easily done.

BuckleScript

BuckleScript compiler is one of the powerful features which takes your reason code and compiles it to readable and performant JavaScript with great dead code elimination. While performing React native app development I am sure you will appreciate the readability if you’re working on a team where not everyone is familiar with Reason, do you know why? Because you will still be able to read the compiled JavaScript code.
