Hiring and finding out the right talented React developer is challenging. While searching for the right candidate, various factors such as technical proficiency, experience, skills, and more should be considered before hiring a developer.

Key Factors to Know before Hiring Reactjs Developers

The popularity and usage of Reactjs continue to rise, businesses are inclined to develop the application using this framework. However, before you hire a remote offshore developer, it is crucial to evaluate the developer’s experience and knowledge of the technology. Let’s look at the major factor in hiring a dedicated react developer.

What is React?

React is an open-source JavaScript library for developing rapid and interactive user interfaces for both web and mobile applications. In the Model View Controller (MVC) architecture, React is the “View” that works on the look and feel of the application.

What are the Responsibilities of React Developers?

  • The developers need to create quality and error-free UI code using the mock designs and wireframe.
  • Constant monitoring of the code is required to enhance the performance of the application.
  • React toolkit is used to build interactive components of the user interface.
  • Create and optimize HTML/CSS/JavaScript components and make them cross-compatible.
  • Write concise, expressive, and modern UI code using JavaScript features, stylesheets, and CSS-preprocessors like SASS and LESS.
  • Manage application state and functional libraries to make asynchronous API calls and derive computed data from the state using React workflows like Redux and Context APIs.
  • Go through the quality assurance (QA) process, which includes unit testing, end-to-end testing, and integration testing.

6 Things You Should Know Before Hiring ReactJS Developers

The popularity of React increases the demand for React Developers. It is mandatory to hire skilled and experienced developers who can develop the flawless application. Let’s go through the skills needed in the developer while hiring React developers.

Proficiency in HTML and CSS

The software developer must stay updated with the latest coding trends. The developer should be familiar with HTML and CSS languages. The React developers should have a strong command of developing.

The software developer must stay updated with the latest coding trends. The developer should have strong command over HTML and CSS languages for the front-end development of the application. The React developer needs to do the following:

  • Semantic coding of HTML tags
  • Use the Code CSS selectors appropriately
  • Deploy a CSS reset
  • Knowledge about box model, flexbox etc.
  • Should know the principles to deploy responsive web design
  • Use of media queries properly in the app project

Experience working on JavaScript Syntax Extension (JSX)

The software developers generally do not use the HTML properly with the ReactJS framework. JSX is a syntax extension to JavaScript or the extended code syntax that is an important aspect of the ReactJS ecosystem.

HTML and JavaScript are the combinations that allow the developers to write HTML structures in the same file that contains a JS script. JSX allows displaying useful error and warning notifications. The important areas to have commanded as a React developer include the following:

  • Variables and scope of use
  • Array methods
  • DOM Manipulation and event handling
  • JavaScript Classes

Are the developers experienced in working with Version Control Systems?

Working on a complex software project requires multiple developers where developers need to collaborate and make frequent changes in the code. The control system streamlines the development process and helps with code management.

This is the main reason why developers need experience working with version control systems. This enables developers to keep a track of changes done while developing the project. Furthermore, developers can also review the old code and can compare it with new code.

Developers use multiple versions of the control system, including Git, SVN, TFS, and Mercurial. Developers mostly prefer to use Git to store the project on the code hosting platforms like GitHub, Bitbucket, and GitLab.

Experience working with ReactJS workflows

The biggest challenge for frontend developers is the state management in React applications. It is advisable to hire developers with experience working on projects where they have managed the state of the application components and optimized the application performance.

Check their knowledge of the popular libraries and structures of state management such as Redux, Mobx and Context API.

Do developers know Adjacent Technologies?

The developer should have experience working with multiple technologies that are compatible with React. With the help of NodeJS, a developer can fulfil the client-side development needs. The NPM package that comes with NodeJS can easily be extended to the React library.

In addition to this, the developer should have good command over MERN Stack (MongoDB, ExpressJS, ReactJS and NodeJS). It helps to build full-stack JavaScript applications. Furthermore, they are the most compatible and popular backend technologies used with React.

Tools that React Developers must know

React developers should have experience working on the following tools:

  • Bitrise tool is use for development automation.
  • Hockeyapp tool is use for reporting app crashes, managing testing, and beta version distribution.
  • Redux is use for state management
  • ESLint tool is use for evaluating the code to comply with JavaScript
  • Testing the JavaScript code, the Jeet tool is use
  • NPM registry is the hosting tool for all software tools for the app project

Last Words

Hiring an experienced and knowledgeable React developer for the project is never easy. You should ensure that React developers you hire are keen to keep themselves updated and learn about technological changes that come up in the industry. Interview questions for React Developers vary on the position that you are willing to hire. The above-mentioned points will surely help you to hire the right and experienced developer.
