As an entrepreneur who is looking for a digital partner for the development of their very own application, it can be difficult to follow the technical jargon that’s mentioned in many consultancy meetings and proposals. If you’re not a software developer yourself, the information regarding technical specifications can be complex and difficult to understand. As a company of digital experts, we want to make sure our clients are always on the same page as us, no matter how complex the topic. That’s why we have been taking a deep dive into the technologies and frameworks our development team at Lizard Global works with on a daily basis. Last time, you could read about NodeJS, an indispensable part of the MERN tech-stack. This week, we’re having a look at another programming language of MERN: ReactJS.
The tech stack of MERN
MERN has a considerable following in the app development community. Many problems that arise during the development process are solvable with the knowledge of the community, and documentation is freely available. It also has a low learning curve, which means that developers don't have to spend months learning the languages and frameworks before they can start using them. Another essential aspect to note is that all of these technologies are open source and free, removing any concerns about licensing.
ReactJS is an open-source, component-based front-end library that is only responsible for the application's view layer. The view layer is the part of the program that is visible to the user and interacts with them. The Business Logic Layer is the layer in the middle, and it acts as a bridge between the View (or presentation) and the Data Layer, which is the deepest layer. Facebook is in charge of keeping ReactJS up to date. React employs a declarative approach, aiming for efficiency and flexibility. It creates basic views for each state in your project, and when your data changes, React updates and renders the component quickly. Your code will be more predictable and easier to debug using the declarative perspective. Each component in a React application is responsible for rendering a small, reusable piece of HTML.

ReactJS in MERN
The MERN tech stack is designed in such a way that the languages and frameworks within the stack work together in a streamlined and efficient way. NodeJS and ExpressJS are used to build the backend of an application, while MongoDB is a No-SQL database that’s used to store all the application’s data. For example, if you are building an HR application, the Mongo DB will have all the employee details, salary details, leave days etc. stored securely in this database. ReactJS sits at the top of the MERN stack. React allows you to create complex interfaces by connecting simple components to data on your backend server and rendering them as HTML. React excels at handling stateful, data-driven interfaces with minimal code and suffering, and it comes with all the bells and whistles you'd expect from a modern web framework, including excellent support for forms, error handling, events, and lists, among other features.
React can request required information from the backend, and display it to the user. In an application, however, not all data is required at the same time. Therefore, based on the carefully thought-out UI designs provided by our expert UI/UX team, our developers build views with React UI components that will only request the required information at a given time and display it to the user.
React has state updates that allow an application to re-render only specific UI components, without reloading the whole page. This increases the performance and provides users with a better user experience. From a development perspective, React also allows the creation of reusable UI components. This helps developers to keep the code clean and concise. Some people might know ReactJS from the term “React Native”, which is the same as React, but uses Native libraries for native mobile app development. Apart from the advantage of building one code base for both iOS and Android, saving time and money, React Native also has great performance, which makes it look and feel as if it was built using the specific iOS or Android Native Platform code. React Native also allows developers to directly communicate with the Native Modules, such as Location APIs or Camera APIs to create better-performing apps while using mobile technology to its fullest.
Using ReactJS at Lizard Global
At Lizard Global, our developers have been using ReactJS since its birth in 2013, while with time other frameworks such as AngularJS, VueJS, NextJS etc. came into play. While the development team has been experimenting with all these frameworks, we have not found a compelling reason to move away from ReactJS. All frameworks are continuously evolving and have a solid community of developers. That said, we do use NextJS from time to time where the speed of server-side rendering is an integral part of the solution.
