Factors to Consider Before Hiring a React JS Developer

With more than 9,600,000 live websites and 10,234 renowned organisations using ReactJS worldwide, Hiring React JS Developer is only profitable. However, not every ReactJS developer is the same. Therefore, you need to consider several factors to choose the best developer. So, here given are vital factors to consider before hiring a ReactJS developer:

●      Knowledge Base in the Relevant Technologies 

Mastering a single technology is not sufficient for a ReactJS developer. They must be capable enough to work with several related technologies and React-compatible frameworks such as Ruby, Laravel, Rails, Django, and many others. 

●      Proficient at Planning Tasks and Sprints for Independent Projects 

Whether the hired ReactJS developers will report to the project manager or not, it’s a must for developers to plan and organise their duties independently. Moreover, they should be efficient enough to meet the timeframe set for independent projects. It will be a plus point if they are well-versed in task management tools to track the progress of sprints.

●      Experience Carried in Relevant Field 

Since web development involves a practical application, hiring an experienced ReactJS developer is always best. In addition, a web developer can sharpen his skills by practising them for years.

●      Different Skill Sets Required for React JS Developer

Hiring ReactJS developers with the below-listed skills is necessary to meet significant duties and perform result-oriented jobs:

–        Basic Knowledge of EcmaScript and JavaScript

A ReactJS developer who knows the JS features, syntax, and functions and has detailed knowledge of EcmaScript can create responsive web-based and static applications. In addition, they must have enough experience in dealing with DOM manipulation, JavaScript scopes, functions, ES6 syntax, event bubbling, and hoisting.

–        Basic Knowledge Base of CSS Styling Methods

The React ecosystem is enormous and contains reusable parts in large numbers. Therefore, it is a must for a ReactJS developer to be well-versed in styling tactics and React fundamentals.  

Regarding styling methods, the developer should have a basic knowledge of CSS styling techniques (JSS, JS-In-CSS, CSS preprocessors, and CSS frameworks), React components, and third-party styling libraries to build engaging user interfaces. 

–        Testing Frameworks and Tools     

 A professional ReactJS developer will always know how to use unit testing frameworks and technologies, such as Chai, Jest, Mocha, Tape, etc. Moreover, they should have excellent command over integration testing tools, end-to-end testing tools, and frameworks like Karma, WebDriver work, Selenium, CucumberJS, Puppeteer, and more. 

–        Basic Knowledge of Version Control Systems

A trustworthy version control system is necessary to speed up the development process when developing a complex React application. In such a case, you should put together a team of competent ReactJS developers who are well-versed in an array version control system (VCS), like Git, TFS, Mercurial, firebase, SVN, and others. 

Furthermore, ReactJS developers with a basic knowledge of VCSs come to help compare old-new code, analyse current code, and minimise errors quickly and effectively. 

–        Strong Hold on JS Build Tools

A ReactJS developer can be called proficient when he can maximise the React library and deal with build tools. Hiring front-end ReactJS developers with a firm hold on JS tools, like Redux, DevTools, and react developer tools (Google Chrome), can be a plus point. Some popular build tools include yarn, Visual Studio Code, NPM, and Webpack.

In addition, ReactJS developers should be well-versed in optimising workflows, installing and handling packages, and controlling dependencies with the help of these JS Build tools. 

●      Flexible Learning Curve

ReactJS is one of the finest libraries for web development, and it undergoes enormous changes and progresses every other day. Therefore, it’s worth hiring ReactJS developers who are dedicated enough to learn technology updates and changes when required.

Agency vs In-house React JS developer
