How to Become a Freelance ReactJS Developer

If you like being creative and working with cutting-edge technology, then a job as a freelance React.js developer might be right for you.

What does a freelance React.js developer do?

React.js developers write code to create tools that can be run directly within the browser or as an app to make websites, tools, video games, and more. React.js developers commonly work with related tools such as Node.js, but knowledge of Node.js is not explicitly essential for React.js developers.

While a college degree isn’t necessarily required, a good background in coding (specifically JavaScript) is always a great thing to show potential clients.

What skills do I need to become a React.js developer?

React.js is a JavaScript library that provides a framework for developers to easily create tools and software without starting from scratch every time. React.js delivers a lot of functionality, but you need to have a solid understanding of JavaScript and class-based programming to be able to use it. A bachelor’s degree in computer science, software development, or other related fields is recommended. Attending a boot camp also helps.

Common skills a React.js developer should possess include:

  • Good understanding of the JavaScript programming language and class-based programming (CSS, HTML, Java, etc.)
  • Familiarity with related tools and React applications that are commonly paired with React.js, such as Node.js, Redux, Node Package Manager (NPM), and jQuery
  • Good understanding of asynchronous programming concepts for web development and web applications such as REST, callbacks, and hooks
  • Familiarity with version control software such as Git and GitHub
  • Ability to work with other front-end developers, full-stack JavaScript developers, and other web developers

What are the job responsibilities of a React.js developer?

React.js developers may be tasked with creating various tools, from websites to apps, and microservices that are consumed by other tools.

Very often, React.js is paired with other JavaScript tools such as Node.js and React Redux. A React.js developer will use all of these tools and other software libraries to create new software and maintain existing software. Common job responsibilities include:

  • Developing the back-end structure to support websites and apps using HTML
  • Integrating third-party APIs and software libraries into existing projects
  • Working with other tools such as version control software and Node.js for development and deployment

Upwork is not affiliated with and does not sponsor or endorse any of the tools or services discussed in this section. These tools and services are provided only as potential options, and each reader and company should take the time needed to adequately analyze and determine the tools or services that would best fit their specific needs and situation.
