What is ReactJS? 

ReactJS is a JavaScript library, which is easy to learn, reusable, fast, and responsive. It is touted to be the best option for building single-page applications of any scale and size. With all these attributes playing out in its favor, ReactJS is all set to dominate the developer community, job market, and technology landscape.  Data suggests that ReactJS adoption is nothing less than a wildfire. With a lot of big names under its belt who have already migrated or in the process the growth rate of ReactJS is likely to only go higher in the coming years. Besides Facebook, React JS is used by digital pioneers like Uber, Airbnb, Netflix, Amazon, Instagram, Twitter, Shopify, Microsoft, WhatsApp, Atlassian, Codecademy, Dropbox, New York Times, Asana, Intercom, Slack, Storybook… the list goes on. 

Furthermore, ReactJS is among the Top 5 Digital Skills that companies are looking for when hiring developers. The open positions for ReactJS developers grew by a whopping 184% last year compared to 2019. Smart developers know this and are fortifying their skills with ReactJS.  According to Statista, JavaScript is a choice of 67% of developers, and ReactJS is the first choice of developers between all the JS frameworks.

Data doesn’t lie: ReactJS- Most Used & Loved Framework

To put it in simple words, front-end developers just love ReactJS. In fact, in a recent survey done by Stack Overflow ReactJS was voted as the most loved framework by developers.

Another report suggests that over 71% of developers who have used ReactJS want to use it again.

According to the below chart from the State of JavaScript report, which shows each technology’s ratio of satisfaction over its user count, in four quadrants: 

• ASSESS Low usage, high satisfaction, worth keeping an eye on. 
• ADOPT High usage, high satisfaction, technologies safe to adopt. 
• AVOID Low usage, low satisfaction, Technologies to avoid
• ANALYZE High usage, low satisfaction, Reassess, is already using it. 

ReactJS falls under the ADOPT quadrant (High usage, high satisfaction. technologies safe to adopt). It is not a surprise that ReactJS has garnered 164.1K GitHub stars by the developer community. At the same time, over 9000 companies use the framework in their tech stacks.

ReactJS- Raging Popularity as Web App Development

Before anything else, let us answer the big question –  what are the factors behind the raging popularity of ReactJS? 

1. Very Easy to Get Started

Thanks to its simple design, use of JSX which is very HTML-like syntax for templating, and highly detailed documentation. Add a small little code generator to the mix and things start to fly, isn’t it? 

2. Reusable Code

Developers spend more time writing JavaScript business logic rather than worrying about the framework-specific code.

3. Fast and Responsive

Owing to the virtual DOM implementation and various rendering optimizations the memory data structures in ReactJS are converted to components. These ReactJS components update and modify the browser by running the computation tasks. VDOM renders these components, data, and elements so that they can be processed and utilized further.

4. Server-Side Rendering

Great support for server-side rendering, making it a powerful framework for content-focused applications. fewer browser compatibility issues, data security, and less loading time. 

5. One-way Data-Binding

Redux, the most popular framework for managing application state in React, is easy to learn and master. Some values can be passed as components and rendered in HTML tags as properties. But, it is difficult to change and access them directly. However, ReactJS allows developers to access components and directly change them by enabling the call back function. This ReactJS property is referred to as properties flow down and actions flow up. 

6. Type Safety

Microsoft’s TypeScript or Facebook’s Flow has native support for JSX and can help in making applications type-safe.

7. SEO Friendly

Applications built on ReactJS are SEO friendly, helping in higher discoverability and visibility of the apps.

8. Native Applications

ReactJS lets developers build Native Mobile Applications by reusing code-With ReactJS you can, not only build high-end Web Applications but also develop Native Mobile Applications (iOS and Android), by using the same code which can be modified with the help of React Native. 

Benefits of Choosing ReactJS vs AngularJS or Vue.js

There are approximately 24 JS frameworks. Most popular being ReactJS, AngularJS and Vue.JS. So, how does ReactJS compare to AngularJS and Vue.js? Here’s a quick overview:

AngularJS

 Angular is the oldest in the race for JavaScript MVVM framework, founded in 2009, which is awesome for building highly interactive web applications. So, you can also hire AngularJS developers to fasten your development work. 

Benefits of AngularJS 

• Angular is created to be used alongside Typescript and has exceptional support for it. Thus, the strong type support makes the framework pretty robust to work with. 
• AngularJS boasts of some new features like Angular-based npm libraries from CLI, generation and development of Angular-based Web Components, etc.
• AngularJS has detailed documentation that empowers the developers with all the necessary information.
• It enables singular behavior i.e., one-way data binding, thus the app resulting in minimized risks of errors. 
• The MVVM model (Model-View-View Model) enables developers to use the same set of data and work independently on the same section of the app.
• Dependency injection of the features related to the components with modules and molecularity in general.
• The AngularJS structure and architecture is specifically designed for enhancing scalability of flexible projects.

Drawbacks of AngularJS: 

• It can be difficult to learn in comparison to the other options in the comparison. 
• Relatively slower performance, according to different benchmarks. 

AngularJS vs ReactJS

• ReactJS supports Unidirectional data binding and AngularJS support Bi-directional data binding.
• Compared to ReactJS, AngularJS is difficult to understand. The reason is the support of third-party syntax and libraries.
• ReactJS is an Open Source Framework while AngularJS is an MVC framework.
• ReactJS works on Virtual DOM and AngularJS works on Regular DOM.

Vue.JS 

Vue.js, a JavaScript framework, was launched in 2013. It is a flexible framework with advanced web tools to develop modern SPAs (single-page applications) and front-end web apps.

Benefits of Vue.JS: 

• Detailed Documentation-  Vue.js has very clear documentation which can shorten the learning curve and makes it easy to start. 
• Familiar Interface- It provides a rapid switching period from other frameworks to Vue.js because of the similarity with other frameworks. 
• Better Integration- This framework can be used for developing both single-page applications and also complex web app interfaces. 
• Focus on scaling to develop pretty large reusable templates. 
• Tiny size- Vue.js is a lightweight framework of around 20KB.  As a result, it is a fast and flexible framework that allows for efficient performance.

Drawbacks of Vue.JS: 

• A small developer community and lack of support make it hard for developers to find solutions to problems.
• While enterprises like Xiaomi and Alibaba have adopted Vue.js and it has helped in popularizing the framework. The popularity ratio remains higher in China and a major part of the content and discussion around the framework is in Chinese.
• Vue.JS has a two-way data binding for managing DOM updates. The issue with the reactivity system is that it renders only the chunks of data that were triggered and often makes mistakes during data reading, which requires data to be flattened.

 Vue.JS vs ReactJS 

• Vue uses HTML templates while React uses JSX. JSX or JavaScript Expressions is integration of CSS and HTML into JavaScript. It is an XML-like syntax that enables developers to develop UI components that are self-contained along with view-rendering instructions.
• Apps built on React have faster performance than the ones built on Vue. The addition or extension of a component makes the Vue app slower to load.
•  ReactJS caters to the view layer of an application that is made up of components and Since doesn’t have a built-in architecture pattern. Vue follows the View Model approach and undertakes the pattern on MVVM especially while developing a large-scale application.

In Conclusion:

A lot of factors are involved while choosing the best framework for web app development. Speed, performance, stability, affordability are a few variables that make ReactJS a perfect choice for the development of web apps, especially for large-scale enterprises. No wonder, even giants like Twitter, Instagram, Netflix, trust this framework.  These frameworks are evolving at a faster rate and are in close competition with each other. For the success of any app, the best technology and design have to come together.

Given the ever-evolving landscape of technology it can be difficult for enterprises to have skilled resources in all these areas. However, a staff augmentation partner like EngineerBabu can help you find the best developers across technologies and skills.

Usually people get their Product developed with freelancers or small agency, They select the best technology “React & Node” but forget check quality code. Problem comes when product scale.

To Optimize ReactJS; Here are steps you should follow

Problem 1:  is this because of Poorly written Code: 
If your developer team has written poor code ( hard to read and understand, multiple APIs call, Not using standard naming for variables of methods, Not reducing unused code) .

Solution: Hire an Experienced React Engineer and ask him/her to create detailed report about code quality.

How to hire this expert just for auditing and reporting.

• Use Upwork “Hire React Freelancers” ( Price $400/hour to $50/hour)
• Hire ReactJS Developers at EngineerBabu under $100 for 7 hours

Problem 2 : You purchased React Theme from themeforest 
Solution : We got one customer from Singapore; He wanted to launch his product quickly.

He purchased Metronic, React theme and advised us to use same to save time and money.

Though it looked beautiful at first, it was one of the bad decisions he ever made. The code has unnecessary JavaScript calls that reduced the speed and performance of the application.

Rapidly ReactJS has grabbed the attention of numerous renowned companies and services and rebuilt their product. Hence, the most prominent and familiar names of SaaS applications that became an essential part of our lives are- Instagram, Yahoo Mail, Netflix, Reddit, and many more.

ReactJS has effectively met the user’s expectations and helps all levels of developers, whether you are a novice or an expert, to develop the product with ease and perfection. From 2015, ReactJS has been available as an open-source, where its libraries are majorly used for creating the user interface.

Developers can create large web applications with ReactJS in which data can be changed without reloading the application. It can be used in association with different JavaScript libraries such as Angular in MVC.

ReactJS development usually depends on the development of components for Single Page Applications (SPA); the pages effectively work independently to each other. These individual blocks are responsible for a specific function in the application. The components can be rearranged to build a new and complex system.

Important Features of ReactJS Development for SaaS Products

1. React Native

ReactJs has a Native library introduced by Facebook in 2015. The native libraries have been a tremendous advantage for native applications such as Android, iOS, and UPD that render the react architecture. It is majorly used for developing a mobile application framework by using JavaScript.

React Native follows the same design as React and allows developers to use the rich mobile User Interface components. It uses the basic fundamental UI building blocks for all Android and iOS Applications.

2. JSX

React uses JSX features for templates. It is an easy JavaScript platform that serves efficient HTML quoting. It also uses the syntax of HTML tags to deliver the sub-components. Those syntaxes are further moved into JavaScript for the holistic React framework.

3. Single-Way Data Flow

In ReactJS, a group of values is transported to the component’s renderer as the HTML tags properties. It is not possible to directly update or change any property by the components. However, it can surely deliver a callback, which helps in the modification or updation of properties.

4. Virtual Document Object Model

ReactJS development provides an in-memory data structure cache to monitor changes by updating the browser. This results in the activation of a unique feature that supports ReactJS developers to code.

Reasons to Use ReactJS Development For SaaS Products

1. JSX- An HTML like Syntax

React uses JSX syntax, which is an extension to JavaScript. JSX seems like a template language, but it has all the abilities of JavaScript language. It partially follows the coding structure. which neither can be termed as HTML nor a complete string.

This coding structure seems quite funny for strict developers, but nowadays, it has become a trend in the market. It is a unique way of producing React elements. React embraces the fact that rendering page logic is inherently paired with other user interface logic. However, JSX supports attaining the results by managing the different concerns with loosely coupled units, i.e., components.

This makes the web and mobile development technologies unique. Hence it attracts more projects on a daily basis, and ReactJS for SaaS products is preferred above other languages.

2. Virtual DOM

The Virtual DOM is a programming concept where an ideal or virtual representation of User Interface is stored in the memory and synced with the original DOM through a library like ReactDOM.

In easy language to understand Virtual DOM- Virtual DOM is the representation of a DOM object. It is simply like a copy of DOM and is much lighter in terms of its expression.

Virtual DOM is beneficial for ReactJS in multiple ways and in a broader way. ReactJS’s virtual DOM renders the JSX and compares its snapshot grabbed just before the update. With this, ReactJS finds out exactly which VDOM object is changed. After this analysis, only those objects are updated in the original DOM. The whole process of finding and updating objects is termed as “Diffing”.

Hence, it is the most crucial part of ReactJS to analyze and update only the necessary part of the DOM. Therefore, it serves to guarantee a better user experience and high performing application. Hence, makes ReactJS for SaaS products to be the most suitable platform.

3. Clean Abstraction- Free of Architecture

It is one of the strongest and most positive points about React that it does not force its users to learn the internal processing. The developers only need to know the life cycle of component’s, props, and the states to get a good understanding of ReactJS. It is not mandatory to understand or learn the internal processes, unlike other programming languages such as the digest cycle of Angular JavaScript.

React does not force any strict rule or procedure to follow any architecture or pattern, such as MVC or MVVM. The developers are free to develop and design the app architecture in any manner they like or which suits them best.

4. One-Way of Data Flow

React follows a one-way of data binding. It allows data binding in the downward direction and ensures the data updates or changes in the child structure don’t affect their parents. The mechanism followed to implement the one-way data binding is termed as “Properties flow down, actions flow up”. Hence, it makes the component to restrict the passed on properties modification. As a result, the developer had to modify the state and implement the updates to change and object.

Well, it is quite difficult for many developers to understand how the on-way data flow supports a language to survive. However, it is not that complicated to understand. Because of its clean data-flow structure, the better control of the app can be accessed. As a result, ReactJS follows this architecture to deliver the best results.

The one-way of the data flow approach also makes the coding more predictable and easier debugging if anything goes wrong with the application. One-way of data flow is best with ReactJS for SaaS products to ensure the high quality of customer experience and service.

5. Composable Component- Compatible with Code Reusability

The logic of Components is written in JavaScript, not in Templates. JavaScript makes it easier to pass the data through your app. This approach makes it possible to make the application to keep the state out of the DOM.

React is used to build the applications by using components, and this combination of components results in a big part of application development. Therefore, these components are developed with Reusable codes. Thus, React is known as the language of Reusable components, which increases the overall productivity of the developers. The reusable components also ease the work of Testing and Debugging.

As compared to other frameworks and languages, React stands out among all with the best standards, less complexity, and is based on the brilliant strategy of code reusability. React uses encapsulated components that use their own states, which are developed to deliver unique user interfaces and make ReactJS for SaaS products most appropriate.

6. SEO Friendly

SEO has become the basic necessity of any website, as each day, there are numerous developments and innovations in the IT industry. Many JavaScript frameworks have been built to date, but all follow and serve different purposes when it comes to SEO.

Usually, JavaScript frameworks don’t fit appropriately with search engines. This results in a negative impact on the ranking of the web pages built with JavaScript. However, React is free with all the negative impacts and manages all the problems involved in SEO rankings very smoothly.

ReactJS for SaaS products also serves features used to run the application on the Virtual DOM and server. Thus, it can easily represent the web pages on the browsers efficiently. Hence, it results in React as the SEO Friendly language and can be easily read by different search engines crawlers.

7. Supportive Developer Toolset

The best toolset is the necessary requirement for any developer and is aware of each and every feature of the new technology. It will make the project development process relatively more manageable and comfortable. Therefore, to fulfill the requirement of libraries or frameworks, the developer should be ready with all the features and the tools, so that you can effectively use them.

React is available with many features, along with designing and debugging tools. Such tools include starter kit, ready-made login modules for Google and Facebook, UI Components and Widgets such as Color Picker and Infinite Scroll. Some Routing Tools in React are also available such as Aviator Router, Component Router, and React Router.

ReactJS for SaaS Products also provides some pre-build tools such as Webpack, Babel, and Create React App. Apart from that, some of the crucial debugging tools are React Inspector and React Developer Tools, which makes debugging tasks a lot easier and faster.

ReactJS also offers some testing tools, and are Enzyme, React Unit, Jest are some of the major testing tools available and used by a majority of developers.

8. Uses REDUX- Convenient State Management Tool

Redux is a very convenient state management tool used for JavaScript applications. It is efficiently and frequently used with React applications. Redux can also be effectively used with other frameworks and provides functionality to explain the user interface as the function of the state. It helps in presenting the updates in the states as a result of the actions which are implemented and taken over it.

Redux helps to ease the storage and management states of components. It is very important and helpful in large applications that possess numerous dynamic elements.

Some Redux tools are available which support in making the tasks more manageable. Apart from that, many React tools are also there, which helps in building an integrated application between the ReactJS development and the Redux. Hence, ReactJS for SaaS Products is considered the best and most appropriate language for development.

9. Supports Server Side Rendering (SSR)

Server Side Rendering is one of the most important features of ReactJS development that allows pre-rendering of the initial state of React Components at the server side. With this feature, the loading of pages gets faster as it doesn’t require to wait for all the JavaScript to load before actually getting the web page visible or appears.

It is a wonderful technique to render a general client-side single page application (SPA) on the server and then allowing the fully rendered page to the client. This process helps get the right place in SEO rankings and makes it easy for search engine crawlers to identify the content.

Thus, such features are considered for building an interactive user interface application, and ReactJS for SaaS products seems the perfect solution.

10. React Native Framework to Build Interactive Mobile Applications

React Native framework works on the similar logic of React, which serves a hands-on advantage of reusing almost 95% of the React codes to build a wonderful and interactive mobile application. The Facebook team developed React Native for hybrid app development, i.e., for iOS and Android, both in 2013 to ease the complete app development process.

Major Challenges Traditional SaaS Product UI Experiences

ReactJS for SaaS products experiences major challenges for product UI. Today having an engaging user interface is mandatory for engaging the long-term users. Therefore, it becomes mandatory to optimize the complete user experience with custom SaaS design.

The design of SaaS products is typically focused on goal-driven behavior. The product owner usually first identifies and then develops the set of functionalities for SaaS products or services. As a result, it fulfills both business goals and end-users expectations.

Despite that, the owners fall short of some common UI issues that get least preference by the business owners. Hence, these are the major challenges that business owners face in traditional SaaS product UIs. Though ReactJS development for SaaS products supports overcoming such situations, it requires the owners to be aware of those issues in advance.

Let’s take a look over the following challenges that traditional SaaS products UI experiences.

1. Basic Layout

The application website layout is built with several elements that are directly accessible at the users-end when they are on the dashboard. Such as, Search Tool, Visual Access, Sidebar, etc. are the common elements that a user expects while interacting with a web application.

The manner in which you arrange all elements together to represent your business story leads to the layout structure.

2. Possible Solutions

The Home Page is the first page that appears to users, and it is the very first impression on users. However, the not so attractive UI is affecting user’s preference over the application.

The users usually prefer a solution for them in the form of an app that is simple and easy to go with it and is less error-prone as well. A possible solution can fulfill the need for an impressive layout and selecting a progressive disclosure. It shows the simple and important options instead of overwhelming users with each and every information.

It will simply divert the focus to the most important features, without affecting them with presenting or showing so many categories at once. For example, the graphic designing platform ‘Canva’, is a wonderful example of progressive disclosure. Here a user sees fewer yet important features at a time; however, a lot of choices are always available for them. So, without a doubt, using ReactJS development for SaaS products can perform a fair amount of usability optimization.

3. Ease of Use

Just merely building a SaaS product to meet all your requirements doesn’t assure a successful business. It has to be comfortable and straightforward to use at the time user visits or sign up. However, following a traditional and original approach might always won’t work perfectly.

Poorly designed websites or Saas products easily derive the need for redesigning of SaaS user interfaces. The bad design also causes overlapping or hiding of relevant and valuable information, so it becomes important to design the product in a way that can ease the complete user experience.

Possible Solutions

Ensure to organize all the information, pop-ups, tutorials, widgets, and functionality in a manner so that users can access and use all functionality efficiently and appropriately.

Choosing an easy and convenient layout for your SaaS product designing will make your product mobile responsive too. Whereas, the layout for desktop users which you are designing by using ReactJS development for SaaS products should have to stay structured and well-aligned on the small screen devices without any hassle.

The SaaS products require excellent functionality apart from wonderful layout and visuals. Apart from that, to attain such perfection usually gets affected by the specific requirements of clients to add some unique features and functionalities. It increases the hurdles towards serving a clean and smooth user experience for their business.

However, this can only be conquered by choosing a custom approach with ReactJS development for SaaS products.

Why Build A SaaS Product by using ReactJS Development?

The following benefits support the claims of adopting ReactJS Development for SaaS products as a better option than building a traditional software;

• To maintain a Centralized Platform is quite easier and more affordable in SaaS products as compared to the traditional desktop software’s.
• The cloud-based software is not very easy to build the duplicate or provide pirated software. Hence SaaS products are the best option for companies to minimize the piracy of their software.
• With ReactJS development, the product upgradation and expanded service delivery to the users become easier with SaaS products. Hence, business owners can quickly scale their SaaS applications and boost revenue.
• SaaS products offer a huge user base as it attracts more customers because of its easy accessibility from any device.
• The SaaS products also don’t compel you to make considerable investments in maintaining massive hardware infrastructure.

Some Renowned Examples of SaaS Products

1. Shopify, an Ecommerce platform, is the best example of SaaS products. It serves complete shopping cart software and the hosting user infrastructure. This makes the user experience relatively smooth and fastens the whole shopping process.
2. Google Play, the digital app distribution service, is developed and operated by Google itself. It is an official app store for the Android application platform. It also uses ReactJS development for SaaS products and provides service to millions of users at a time.
3. MailChimp, an American marketing automation platform and a very famous email marketing service provider. It is also a brilliant example of SaaS products. Due to its ease of use, MailChimp grabbed an excellent market within a year and gained the user base from 85,000 to 450,000.
4. Dropbox is a Google product that provides file hosting services. It offers cloud storage, personal cloud, file synchronization, and client software. In the US and all over the world, it was rated the most valuable startup. Dropbox can effectively provide the best user experience and services and use ReactJS development for SaaS products.
5. Facebook has conceptualized ReactJS development, so it won’t come as a surprise when it adopted ReactJS for its SaaS product, i.e., Facebook. Facebook used ReactJS to build and implement its best pointers as Messenger, News Feed, Ads, and many more.

Well, being a developer while working on ReactJS development, it becomes important to be careful and follow the best and essential practices for ReactJS development. These practices will help you as a developer to keep your codes organized in a better manner.

React is the most popular library developed by Facebook, based on JavaScript for building excellent user interfaces. A majority of developers prefer to work with ReactJS library to build beautiful and user-friendly applications. ReactJS allows developers to integrate many exciting components with it. It also allows developers to build their own component and share them with other developers. As a result, ReactJS is the most user-friendly technology in the market among all the new introductions.

Why ReactJS Development?

In the market, there are many JavaScript frameworks and libraries, but React is the most preferred and liked library among developers. ReactJS is the most preferred library because of its ease of working and learning.

It can receive data from multiple sources such as real-time data, initial data, and user input data; the data passes through the dispatcher. Now, the dispatcher forwards the received data to the store, where it ultimately appears for viewing. Now, the view is the part where the user interacts with the application. Hence, whatever the user sees on the browser as the web page is presenting itself to view.

Happenings at the back-end of the framework follow the traditional data flow.

Whenever the data gets added or updated at the back-end, the browser reloads the web page and repeats the complete procedure again. After that, the updated data appears to view for users. But, this traditional method of data flow has a major drawback, i.e., it uses the Document Object Model (DOM). DOM object is created by the browser each time the web page loads.

The DOM can dynamically add or remove data from the back-end. So, whenever the modification is performed, the new DOM gets created for the same page. This multiple DOM creation results in unnecessary consumption of memory and low application performance.

Moreover, DOM manipulation turns out to be very expensive. Hence, the new technology need arises to avoid the issues that occur due to this. Now, ReactJS has been introduced to rescue from this situation.

ReactJS development allows developers to divide the entire application into numerous independent components. ReactJS still uses the traditional data flow, but with some changes in the back-end.

The back-end changes show that each time the data is added or updated in the back-end, ReactJS uses new tactics to manage it. Instead of reloading the complete page, it simply destroys the old page. It then renders the view components with new data or implemented updates and replaces the old view with the new one.

As a result, the wastage of memory due to DOM, React introduced Virtual DOM.

What is Virtual DOM?

Virtual DOM is like any other DOM, which uses a node tree to list the elements and their attributes and content as its Objects and their properties. React renders a function to create a node tree out of the React components. Then it updates the tree based on the mutation in the data model caused by various actions performed either by the system or the user.

The Virtual DOM performs the task in 3 following steps;

1. When any data is added or updated, the complete user interface is re-rendered in Virtual DOM representation.
2. Then, the difference between the new and the old DOM representation is calculated.
3. After calculation, the original DOM gets updated only with the actual changes done. It can also be considered as a patch. The patches are applied only to the affected areas. Likewise, Virtual DOM performs as patches and is applied to the selected elements which are added or updated in the original DOM.

Though ReactJS is easy to learn but to get the desired results, it becomes necessary to follow the best practices for ReactJS development. Let us take a look at the best practices to write better React code in your application.

Top Practices for ReactJS Development

1. Keep Components Small and Function-specific

ReactJS development allows its developers to have huge components to execute a number of tasks. However, the best way of designing components is to keep it small so that a single component corresponds to an individual function. Therefore, a single component should render a specific bit of page or modify the particular behavior. Hence, it delivers multiple benefits of keeping small components and are as follows;

• Function-specific ReactJS development can be maintained standalone, therefore makes maintenance and testing easier.
• Such small components can be reused on multiple projects.
• Components that execute and fulfill the general purpose functioning can also be made available to the ReactJS developer’s community.
• It becomes easy to update the small components.
• The small components make it easy to implement performance optimizations.
• Huge components perform typical tasks, and may also become challenging to maintain.

The creation of a concise component and multiple function specific components is solely based on the organization’s requirements. With ReactJS Development, the developers can build as many as components they require and combine them whenever the need arises in the manner they want to meet the same end result.

2. File Organization

File organization is one of the most important practices for ReactJS development. Like many beginners, ReactJS developers fail to organize files properly in React applications. A proper folder and file structure is not just crucial for React application but also for other applications. It helps to understand the flow of the project and in adding new features in the application.

Create an asset folder to save all your top-level CSS, font files, and images. You can also add a helper folder to save other relevant files for different functionalities. Maintain a folder to save all the components of your React project. Along with the sub-folders for smaller components used by the large components. It will make it easier to understand the hierarchy of components through folders and sub-folders.

3. Reusability is Important; Avoid Making New Components Frequently

By following the rule of one function, one component, the reusability of component features, can be achieved. In other words, the developer should avoid building new components for a function, if the component for the same function already exists.

By reusing the existing components in your single or multiple projects, being a developer, you will achieve consistency and contribute to the community. Apart from that, if any component is huge and difficult to maintain, then it’s better to break it up into smaller components as per your requirements.

The ReactJS developers can also even go further and create a button component that can manage icons. Hence, whenever you need to use a button, you are going to have a pre-build component to use. Making it modular will allow developers to cover multiple cases with a single piece of code. So, aim for simple yet abstract enough while building the component.

4. Merge Duplicate Codes- DRY your Codes

To become a good developer, the one of the most important practices for ReactJS development is to keep codes concise and brief as much as possible.

The process of avoiding code duplication is termed as, “Don’t Repeat Yourself” (DRY).

ReactJS developers can follow DRY practice by scrutinizing the pattern and similarities in existing codes. In this manner, you can avoid duplication and eliminate code repetition. Hence, re-writing of codes can make it more concise and avoid duplication.

The concise coding majorly relies on the reusability principle. For example, the addition of multiple buttons that contain icons, rather than adding markup for each button. Hence, the developers can simply use the icon button component to merge the similar codes and avoid duplication.

5. Use CSS in JavaScript

While working on a project, it is common for ReactJS developers to follow all the CSS styles in a single SCSS file. The global prefix use prevents potential name collisions. However, when the project gets into the development or updation phase, this solution may not seem to be a feasible solution.

There are many libraries that support ReactJS developers to write CSS in JavaScript. The most popular and preferred CSS in JavaScript libraries are Glamorous and EmotionJS.

6. Comment only at Required Places

Being a responsible developer, add comments only at places where it is required and meaningful. It not only serves the best practices for ReactJS development, but it also serves two purposes at the same time.

• It will keep the code clutter free and helps to understand its working easily.
• If tried to alter the code at some point or later, can potentially avoid the conflict between codes and comments?

7. Avoid Using Indexes as a Key Prop

Using Index as a value for a Key Prop is not at all among the good practices for ReactJS development.

React uses Key property to track all its elements in the form of an array and due to the collapsing action of the array. It might also result in rendering the wrong information in the wrong place.  React does not invest time in rendering duplicates. Hence, the two elements with similar keys, React, consider it as the same and can result in elimination of some elements.

8. Don’t use Props at Initial State

Avoid using Props at initial state practices for ReactJS development. It’s better to use lifecycle methods.

9. Name the Component Relevant to the Function

It is one of the important practices for ReactJS development to name the component after the function it executes. This practice makes a component easily recognizable and relevant to its functioning.

The intelligent naming of components can instantly convey what the component does.

Hence, naming a component after its function makes it more useful for the developer’s community as it becomes easy to discover the component.

10. Use Upper Case Letters for naming Component

Other important practices for ReactJS development should be followed is the use of Upper Case alphabets to name the components you are building. For Example, name components as ‘SelectButton’ instead of ‘selectbutton’. It becomes easier to identify and read the name of components so that JSX can identify it differently from default HTML tags.

11. Other Naming Conventions

While working with ReactJS development, being a developer, you would generally be using JavaScript Extension (JSX) files. The component that you create for React should have to be named in the Pascal case or upper camel case. The naming format translates the names without spaces and the capitalization of the first alphabet of every word.

Suppose you are building a function that submits a form, you can name it as ‘SubmitForm’ in upper camel case, instead of ‘submitForm’ or ‘submit_form’. 

12. Stateful aspects from Rendering

The components in ReactJS development can be stateful or stateless. The stateful components hold information about the state of the component and provide the relevant context. Whereas, the stateless components have no memory to store or hold information, hence they can not provide context to other parts of the User Interface. They are scalable and reusable and are pure functions.

One of the best practices for ReactJS development is to keep the stateful data-loading logic separate from rendering the stateless logic. It is better to prefer a stateful component to load data and another stateless component to display that data. 

The updated version of React v16.8 had a new feature, i.e., React Hooks. It can easily write stateful function-related components. This may also eliminate the requirement of class-based components.

13. Code should be Executable and Testable

Building executable and testable codes is the major priority and the top practices for ReactJS development. It is a good practice to name the test files identical to the source file with a ‘.test’ suffix. Hence, it becomes easier to search for the test files.

The ReactJS developers can also use JEST to test the React code.

11. All Related Files of a Component should be in a Folder

Another important practice for ReactJS development should be followed is to put all the related components in a single folder along with styling files. 

It makes the code extraction easier for any project or can even modify the codes whenever required.

14. Use Tools like Bit

One of the top practices for ReactJS development is to organize all the components by using tools like ‘Bit’.

These tools help manage and reuse the codes properly on the requirement. Apart from that, it makes code discoverable by the community and supports team collaboration in building the components. These tools also enable synchronization of code across projects.

15. Use Snippet Libraries

The snippet libraries for codes help to maintain the best and most recent syntax. These libraries also maintain code bug free. 

 Some of the libraries are, Redux, JS Snippets, ES7 React and many more.

16. Write Tests for all Codes

The adequate testing, regardless of any programming language ensures the addition of any new code integration to the project with the existing code and does not hamper the components and project’s existing functionality. Hence, to maintain the best practices for ReactJS development, the developer should create a ‘Test’ directory within the component’s directory to carry out all the relevant tests.

There are 2 types of tests. First, testing the functionality of components and testing  the complete application once it renders in the browser.

Jest emulates HTML DOM to test React components. Jest provides a good and real testing environment with maximum accuracy during the development phase of the project.

17. Follow Linting Rule to Break Long Lines

Linting is the process of analyzing the codes for potential errors while we run the program.

It used for language related problems. But it can also manage multiple issues automatically, especially the particular coding style. The use of the Linting rule in the ReactJS development code helps to keep the codes relatively error and bug free.

18. Initialize Component State without Class Constructor

Initializing state in class components is not a preferred practice.  It will also increase the number of lines of codes and develop the code performance issue in ReactJS development.

Hence, initialize the state with class fields instead of with the constructor. This practice in ReactJS helps to minimize the noise in your coding.

Conclusion

Over the years, ReactJS development has evolved a lot and ahead towards its maturity, so that hardly it requires to reinvent any step of the development. It resulted in more complexity in choosing what is going to be right for the project.

Every project is different in terms of its functionality and scalability. So, a single or generalized approach can not be followed every time. Therefore, it is important to plan before the development phase starts.

How have ReactJS Evolved Web Development?

The face of web development has evolved a lot in the last two decades, along with the tech-stacks. With the shifting time and technology, the logic moved more and more from the server-side to the client-side.

Initially, the Angular framework has been introduced and introduced the client-side revolution. Later on, ReactJS development has gained popularity and brought the server-side revolution. Let’s understand this revolution in web development in detail.

Web Development before Introduction of ReactJS Development

Before 2015, when web development was majorly about scripting rendering, the languages like HTML, PHP for back-end, and CSS for front-end development ruled the market. The combination of these tech-stacks makes web development quite easier at that time.

The developers need to put static HTML pages in a folder and render them using PHP. However, it is not the most unique or intuitive way to develop a website, as it still requires developing two-way communication between the client and the server-side. This becomes only possible with Server-Side Rendering (SSR).

In this manner, the websites have been developing for decades. But this gets revolutionized after the introduction of JavaScript libraries like ReactJS development.

The Era of Single Page Apps (SPA), ReactJS, and JavaScript

The introduction of JavaScript in the market has revolutionized the web development experience. It provides excellent scope and allows a lot more to do with JavaScript than it did ten years ago.

Hence, JavaScript allows developers to build web apps with client-side scripting.

It allows the Single Page Apps development using JavaScript. However, many JavaScript frameworks allow client-side scripting, whereas Angular is the only one that supports and promotes this approach.

Suppose, you fetch some data via JavaScript, add some attributes to your markup, and now you are good to go. It allows you to build a dynamic website without any issues with PHP and server communication establishment.

In 2015, after the introduction of isomorphic JavaScript library, “ReactJS”, allows developers to build dynamic web applications with rapid speed.

Basically, ReactJS is used to render views in mobile and web applications. It provides a platform for developers to build reusable components that work independently to each other. Reach also introduced a unique feature called Virtual DOM. It allows developers to implement Server-Side Rendering (SSR) without making updates of the complete view each time during the update.

ReactJS out-performs in building dynamic and engaging web interfaces over other JavaScript frameworks such as AngularJS. It is because virtual DOM allows component updation when a user performs any action without affecting other parts of the interface.

What is Exceptional about ReactJS?

ReactJS is very much different from other popular frameworks like Angular or Ember. Unlike others, ReactJS is built on the concept of components and functions with other frameworks as well as libraries like JQuery.

The use of virtual DOM makes ReactJS the quickest library because it merely updates the changed portion of all the web pages. This way of effective working and the architecture of the application makes ReactJS the most productive solution for the developers.

Why Choose ReactJS for FrontEnd Development?

While comparing all the available famous frameworks for front-end development, definitely the best platform is ReachJS for front-end development. Evidently, more than 1,00,000 websites are currently using ReactJS for Front-end development. So, the question is, what made this new technology so popular among developers and business owners?

ReactJS offers a lot of benefits to the developers and the website as well. Still, thinking why to choose ReactJS for front-end development over other reputed frameworks. Let’s see the major benefits of ReactJS to understand why it is at the top of the competition from other front-end development frameworks.

1.Easy to Learn ReactJS Development

React is a very simple and easy to learn lightweight library. It only deals with the View Layer. It is not a heavy framework like Model-View structure such as Angular or Ember. Any JavaScript developer can easily gain its basics and can develop brilliant web applications only in a couple of day’s learning.

On the other hand, if the technology is hard to learn, then it will become difficult to start and attract developers as well. It is human nature that we mostly avoid learning new techniques or anything if it is
