I know what you’re thinking. Let’s hire ReactJS developers. That’s easy too.

Out of 57,378 participants in the 2020 Developer Survey conducted by Stack Overflow, 68.9% of respondents wanted to continue working with ReactJS. However, before you hire a ReactJS developer, read this article first to make an informed decision.

In the next five minutes, you will learn the 8 tips to hire an expert ReactJS developer in 2022:

  • Check if the developer has a strong command over JavaScript and ECMAScript
  • Know if the developer understands testing tools and frameworks
  • Check if the developer is proficient in adjacent technologies
  • Check how well the developer is familiar with JavaScript Build tools
  • Know the experience of the developer in working with Version Control Systems
  • Check if the developer has past experience of working with ReactJS Workflows
  • Check if the developer has deep knowledge of Styling strategies
  • Understand if the developer has a flexible learning curve

Check if the developer has a strong command over JavaScript and ECMAScript

Want to write stories? You must know how to write sentences first.

The same is true for ReactJS which is a JavaScript library. Considering this, if you want to hire top ReactJS developers, make sure he/she must have a strong command over JavaScript features, operations, and syntax. Furthermore, the developer must be proficient in DOM manipulation, event bubbling, JS scopes, and prototypal inheritance.

ReactJS developers need to have proper knowledge of ECMAScript. Why? ECMAScript allows developers to simplify the JS code using the Destructuring feature and to write single-line codes.

Know if the developer understands testing tools and frameworks

Testing tools and frameworks allow developers to write better code. Furthermore, the tools and frameworks help to detect and fix bugs as soon as possible. Thus, you save both time and money.

Thus, check if the developer can perform:

  • Integration testing
  • Unit testing
  • End-to-end testing

Furthermore, the developer must know how to use the following tools:

  • Karma (for integration testing)
  • Selenium, Cypress, Webdriver, Cucumber.js, Puppeteer, and Nightwatch.js (for End-to-end testing)
  • Jest, Mocha, Enzyme, Sinon, Tape, and AVA (for Unit testing)

Among these tools, Jest, Karma, Enzyme, and Selenium are the most popular. Furthermore, React-hooks-testing-library and React Testing Library encourage proper testing practices on React components as well.

Check if the developer is proficient in adjacent technologies

A backend platform or framework is essential to host a React app. Thus, a ReactJS developer must have sound knowledge of backend frameworks such as Ruby on Rails, Laravel, and Django.

Furthermore, ReactJS developers need to be proficient in MERN Stack. MERN Stack refers to:

  • MongoDB
  • Express JS
  • React JS
  • Node JS

MERN Stack is the go-to choose for building full-stack JavaScript apps. Furthermore, MERN Stack is the most compatible backend technology with React.

Furthermore, the Express-React pair is best suited in managing the server load and handling multiple requests. Thus, Express JS helps developers to build scalable apps with React.

Check how well the developer is familiar with JavaScript Build tools

Why do you need JavaScript Build tools? The tools help to optimize assets for production, handle dependencies, and run the development web server. Thus, check if the developer is familiar with the following JavaScript Build tools:

  • NPM: A dependency cloud storage that allows developers to download and install software packages from the NPM registry.
  • Webpack: An open-source JavaScript module bundler that generates a dependency graph. Furthermore, the tool combines all app resources in one file.
  • Yarn: A package manager that manages dependencies, optimizes NPM workflows, and installs software packages.

JavaScript Build tools help automate repetitive tasks. Thus, the development time reduces.

Know the experience of the developer in working with Version Control Systems

If a software project is complex, you must hire several developers. The developers must work in collaboration and make frequent changes to the code.

Version Control Systems streamline the process and help with code management. Furthermore, the systems allow the developers to keep track of the changes. Developers can review old codes, compare the old codes with the new ones, and undo the mistakes in the latest change as well.

Thus, check if the developer is well-versed with Version Control Systems such as SVN, Git, TFS, and Mercurial. Developers choose Git to store projects on code hosting platforms including GitHub, GitLab, and Bitbucket.

Git allows developers to pull the code from their own repository and manage the commit history. Furthermore, Mercurial takes the distributed branching approach whereas SVN and TFS are centralized VCS.

Check if the developer has past experience of working with ReactJS Workflows

What’s the biggest challenge in large-scale React apps for front-end developers? State management. Thus, hire ReactJS developers who have past experience in managing the state across the app components.

Developers need to have experience working with the popular ReactJS workflows such as:

  • Redux: a standalone library that offers a massive amount of application states. However, the application states must be updated in regular intervals in response to actions.
  • Context API: a component structure that helps solve prop-drilling issues. Furthermore, the component structure shares unique data across all application levels.
  • Mobx: a library that allows developers to apply transparent functional reactive programming. The process makes state management scalable.

Check if the developer has deep knowledge of Styling strategies

ReactJS developers must know the below-mentioned CSS techniques for styling:

  • CSS Preprocessors: SASS, LESS, and SCSS for writing styling information for compiling to CSS later. The Preprocessors follow the Don’t Repeat Yourself coding principle.
  • CSS Frameworks: Material and Bootstrap UI make the web development process fast and seamless.
  • CSS-in-JS: The technique allows developers to style components using JavaScript.
  • JSS: The authoring tool writes styles in a reusable, declarative, and conflict-free way using JavaScript.

Understand if the developer has a flexible learning curve

ReactJS developers not only need to have sound knowledge about React but they must learn about third-party libraries, packages, and frameworks. The components include Material UI, Redux, and style components.

Furthermore, ReactJS offers detailed documentation and a huge community. The community shares extensive knowledge of the ReactJS framework. Thus, check if the developer is open to learning and implementing updates and changes when needed.

An expert ReactJS developer can lead your business to success

Developers download ReactJS 7,900,757 times each week. Thus, if you hire an expert developer for such a famous framework, your business can only benefit. In this article, you have learnt that you should:

    • Check if the developer has a strong command over JavaScript and ECMAScript
    • Know if the developer understands testing tools and frameworks
    • Check if the developer is proficient in adjacent technologies
    • Check how well the developer is familiar with JavaScript Build tools
    • Know the experience of the developer in working with Version Control Systems
    • Check if the developer has past experience of working with ReactJS Workflows
    • Check if the developer has deep knowledge of Styling strategies
    • Understand if the developer has a flexible learning curve

I hope the information will help you make an informed decision.
