Qualities to Consider While Hiring React Developers
Are they Outstanding in Related Technologies?
For a Reactjs developer, mastery of one framework or related technology is insufficient. He or she needs to have prior expertise dealing with various React-compatible technologies. We are all aware that a backend platform or framework is necessary to host a React application. React can coexist with Laravel, Django, and Ruby on Rails. Therefore, having an understanding of these technologies provides every developer with a distinct advantage.
Additionally, Express, a Node.js framework, is seen to match well with React for developing scalable apps. Without a doubt, the Express-React combination manages the server load and simultaneous requests the best. Overall, React applications may be successfully created by developers with creative ideas and an in-depth understanding of related technologies and frameworks.
Do they have a Fundamental Grasp of Testing Tools and Frameworks?
Testing has turned into a crucial skill for React developers as a result of the growing demand for speedy deployment throughout the development process. Unit, end-to-end, and integration testing for React code may be done using a variety of tools and frameworks. Among the most popular frameworks and tools are:
- AVA, Tape, Mocha, Chai, Sinon, Enzyme, and Jest (For Unit Testing)
- Cypress, Puppeteer, Cucumber.js, Selenium, Webdriver, and Nightwatch.js (For end-to-end testing)
- Karma (For integration testing)
- The most popular tools, however, for testing React components are Jest, Enzyme, Selenium, and Karma. Additionally, React developers should be familiar with React Testing Library and React-hooks-testing-library, which are tools that promote proper testing techniques on React components and React Hooks.
Developers may avoid mistakes and produce better code by being aware of how various testing tools and frameworks operate. After all, the more time and money you are able to save by finding and fixing errors quickly. Therefore, click the box next to testing proficiency in your technical evaluations when employing React engineers.

- Yarn: A package manager to manage dependencies, install software packages, and streamline npm operations.
Do they have Any Experience with Version Control Systems?
Imagine you’re a developer on a challenging software project that necessitates regular code updates and collaboration between several devs. In these situations, the version control system aids in code management and speeds the development process.
It makes sense to offer precedence to developers who have worked with version control systems. They can use it to maintain tabs on changes to a particular development project. Additionally, it enables examining older codes, comparing them to more recent codes, and fixing errors in the most recent updates much easier and quicker.
Numerous version control programmes are used by developers, including Git, SVN, TFS, and Mercurial, to mention a few. Developers favour Git over other systems for hosting code, such as GitHub, Bitbucket, and GitLab. Developers may control the commit history and pull code from their own repository using Git. Therefore, the ability to monitor various versions of files using the push, pull, add, and commit commands is a must for a developer. In addition, branching and merging are crucial abilities for developers since they enable autonomous code writing. While Mercurial uses a distributed branching strategy, SVN and TFS are centralised VCSs.
Do they have Any ReactJS Workflow Experience?
The largest difficulty facing frontend developers is state management in massive React projects. Look for people whose portfolios speak eloquently about improving application performance and who have experience working on projects where maintaining the state across the application components was clear.
Check to see if they are familiar with well-known state management tools and architectures like Redux, Mobx, and Context API. To synchronise the state of applications across all components, they are employed.
- Redux is a stand-alone state management library with a large number of application states that must be constantly updated in response to actions.
- Using Mobx, a library, state management is made easy and scalable by using transparent functional reactive programming.
- Prop-drilling issues are resolved with the aid of Context API, a component framework to communicate distinctive data across all application layers.
A plus for your team is someone who is knowledgeable about the most recent additions, such as hooks in React 16.8. It enables your team to manage project complexity and turn functional components into stateful ones without having to write a class. Therefore, React developers must have a basic understanding of state and state management frameworks.
Do they Possess a Thorough Understanding of React’s Fundamentals and Styling Techniques?
You require a developer experienced in experimenting with React principles and basics because React is a sizable ecosystem with reusable components. In addition, developers need to understand what the Create React App is and how it functions. It is a tool that aids in providing the first default tools needed to construct a React project. Not to mention, Babel, JSX, Next.js, etc., are some essentials that developers must master in order to excel in creating React applications.
Similarly, it is highly advantageous to hire a React developer who is both a coder and a stylist. Designing highly responsive UIs and creating rich, dynamic UIs requires an understanding of React components, external styling libraries, and CSS methods.
Some CSS approaches are frequently used by developers to style React components since all of these tactics are defined in CSS and are intended to simplify the styling procedures with React.
- SCSS, SASS, and LESS are CSS preprocessors that may be used to create style data that will subsequently be converted to CSS. They adhere to the coding maxim “Don’t Repeat Yourself.”
- CSS frameworks like Bootstrap and Material UI are pre-built elements that speed up and simplify the web development process.
One last test to see if they are familiar with dealing with Material UI and SASS. Large stylesheets are kept structured using SASS as a CSS extension since Material UI is frequently used to design complicated UI components. All in all, having strong CSS and style skills is unquestionably a strength of React developers.
Does their Learning Curve have any Flexibility?
In addition, developers must get familiar with a wide range of third-party software, libraries, and frameworks, like Redux, style components, Material UI, etc. Well, don’t worry! Additionally, it doesn’t take up a lot of time. Redux, for instance, is a simple API that can be learnt in a week.
Additionally, React is the finest library for web development since it is open-source and has a large community of supporters. Because of its simplicity of use and adaptable learning curve, this technology is being adopted by several businesses. As a result, you should make sure the developers you recruit are willing to pick up new skills as necessary.
