FAQs

A React Developer is a person who creates software using the React library, a Javascript framework for building UIs specifically made for single-page applications(SPAs). The key focus is creating interactive, reusable, dynamic user interfaces using component-based architecture.

React developers use React’s component-based architecture, which helps them create reusable components. By using React hooks, component state management becomes more accessible and scalable. Conversely, developers must use frameworks and libraries such as Angular, Vue, or plain Javascript.

The key responsibilities of a React Developer: Implementation of new features and user interfaces. We are optimizing components by creating efficient, reusable, and easy-to-maintain components. Managing the state using Context API and Redux as needed. Testing and debugging the issues and writing the unit test to make the application scalable. Writing reusable components and shared logic to avoid unnecessary code to create well-optimized applications.

React is one of the most popular libraries created by Facebook for building user interfaces, specifically for single-page applications. By using React, developers can make significant and scalable web applications.

React developers use various techniques and tools to manage the state efficiently within applications: Small applications or simple components can be created using React's built-in useState hook or the setState method in class components. The large and complex application requires state management libraries like Redux, MobX, or Recoil, which provide a global store for data access throughout the project. Memorization techniques like useMemo and useCallback can be used to optimize the performance and avoid unnecessary renders.

We are splitting the code by using React.lazy, React.suspense, and dynamic imports are needed to load components only when needed. We use memoization techniques, such as memos, callbacks, and react memos, to prevent unnecessary re-renders. React Virtualized and React Window for rendering large lists by only rendering visible items. Debouncing/Throttling: Implementing debounce and throttle functions to optimize event handling, especially for inputs and scroll events. Optimizing Images and Assets: Using optimized images, lazy loading, and minimizing asset sizes. Avoiding Inline Functions: Avoiding inline functions and objects in JSX to prevent unnecessary re-renders.

At Diligent, we regularly test the application on multiple browsers, including older versions. We use CSS resets or Normalize.css to ensure consistent styling across browsers. Moreover, we use polyfills to support modern JavaScript features in older browsers. The React developers also ensure the UI is responsive and functions well on different screen sizes and orientations. Lastly, an essential part of the REact development routine is debugging and conducting compatibility issues tests, which are done using browser developer tools.

A React developer can integrate a React frontend with an existing backend system. React is agnostic of backend technologies, meaning it can work with any backend system, whether built with Node.js, Python, Ruby, Java, .NET, or any other technology. The integration typically involves API calls to the backend services and rendering the data on the front end.

All sorts of projects coincide with React's functions and operations. From single-page applications to content management systems to e-commerce sites, React is a chameleon in software development.

Our React developers monitor code reviews and use tools such as ESLint and Prettier to create a persistent coding layout. Another trick is to opt for a modular architecture with reusable components. Implementing CI pipelines to automate testing and documentation for code, components, and application structure also helps check code quality.

People choose React as their key web development framework because it has reusable components, a virtual DOM, a rich ecosystem, and an Amazon UI. Frameworks like React.js can also help improve SEO by using server-side rendering.

We at Diligent Technologies take security and user integrity very seriously. During the React development, many security measures were adopted so that data remains untouched by harmful entities. We ensure secure communication with backend services using HTTPS and secure tokens, XSS and CSRF Protection, managing secure user authentication and authorization, and regularly auditing the application for security vulnerabilities.

A React developer can help with mobile app development using React Native, a framework for building mobile applications. React Native allows developers to create cross-platform mobile apps (such as iOS and Android) using a single codebase.
