Additionally, the presence of virtual DOM enhances the performance of complicated apps as modifications can be done without actually affecting the other components in the hierarchy. The strong community support and the presence of inbuilt tools further upscale the app scalability.
True that the application development framework eases the task of development, but to ensure that the framework is utilized to its total potential, you would need an excellent developer, let alone a skilled or an expert.
In case you are planning to hire a react JS developer for your business, ensure that the ideal candidate possesses the needed skills.
What React Developers Should Know?
Top 7 ReactJS Developer Skills
Skills #1 HTML/CSS
React JSReact JS is kind of a front-end development framework. If it is so, what would be a developer without knowing HTML and CSS? The app interface is one of the fascinating things that attract users and lure them into engaging with the same. Irrespective of the type of business or the application you are about to build, every ReactJS developer must possess extensive knowledge in fields of HTML and CSS. And when we say extensive knowledge, we emphasize beyond basic information. Every front-end developer is familiar with HTML and CSS as well as have the ability to work user interfaces and build amazing web applications for enterprise-level organization.
For instance, the ability to work on CSS selectors or the semantic HTML tags are few of the must-haves in a developer. The understandability of border-box, flexbox are a plus.
Skills #2 JSX
Similar to HTML, JSX is the extension of the ReactJS environment and is also a fascinating part of React. When working with react JS, hardly would a developer delve deep into HTML. Instead, much of the interaction is via JSx, the syntax extension of ReactJS.
In technical terms, JSx is the React.createElement() API abstraction layer. What turns JSx to be an important part of the development is the fact that it allows developers to create applications using the above API, which otherwise would be a gruesome task. It is an abstraction on top of the React.createElement() API.
- Variables & Scoping: A common trend of storing variables is to use the ‘var’ keyword, right? With ES6, a developer can take a step forward and choose from a range of keywords such as `let` and `const.` This creates an impression that developers can avoid using var when not needed.
Skills #4 Git
Every developer must be acquainted with the Git toolkit. It gives them the flexibility to add or update projects on different coding forums such as the GitHub, Gitlab, and the BitBucket. Some of the commonly executed tasks comprise merging strategies and handling conflicts, using push and pull to interrogate changes, etc. It is necessary that the developer know how to use these platforms, which includes:
- Keep the track of modifications with a comment.
- Merging and branching strategies.
- Managing merge conflicts.
Skills #5 Redux
The state management library of React, Redux is another essential feature or skill that every developer must-have. Earlier developers have had a hard time dealing with the asynchronous nature of React updates.
To help with this, react came with this hot button feature, namely redux. It is much like the principles of immutability and functional programming. However, do not get mistaken by considering it to be one solution that fits all. The applicability of the same depends upon the state and hence, your developer must excel in it.
Skills #6 Node + NPM
Lastly, the knowledge of the node. Ok, you might find this a little vague, but trust me, a developer that has decent knowledge of nodes can effectively exhibit the development needs of the client-side. There are specific packages in the node that can be extended to the react library; hence the knowledge of the former adds more to the development process.
Skills #7 Should be Skilled at Tools and Technologies
- Sentry for real-time monitoring and fix crashes
- Bitrise – Increased automation
- Hockeyapp – Crash reporting, managing testers, beta distribution
- Redux – Manage the application state
- Jest – Ready-to-use tool for testing JS code
- Enzyme – Facilitate the testing of React apps
In addition to the above, it is expected that the developer is well versed in the NPM registry, a place that hosts software that facilitates the development of another software solution.
The Final Word
Well, hiring a developer could be a stressful experience, but when you know what you are looking at, things turn easier. So, the next time you hire a ReactJS developerhire a ReactJS developer, make sure you are considering all the ReactJS developer skillset stated above. At Bacancy Technology, we always make a special emphasis on the front-end developer essential skills as these are the must-have skills of ReactJS developer.
