React Best Practises Every Developer Has to Follow in 2023

ReactJS has evolved into one of the most prominent JavaScript libraries for creating user interfaces. Its component-based architecture, virtual DOM, and efficient rendering make it a preferred choice for developing modern web applications. As React continues to evolve, developers need to stay updated with the best practises and follow them to ensure clean, maintainable, and scalable code.

It is important to note that ReactJS's usefulness extends to only about 60 percent of developers. Therefore, it becomes crucial to familiarise oneself with the best strategies and practises associated with ReactJS development.

This article aims to provide valuable insights into the world of ReactJS and shed light on the best practises that can assist both ReactJS developers and businesses in building exceptional and high-performing applications. By following these practises, developers can ensure clean and maintainable code, while businesses can leverage the power of ReactJS to create outstanding applications that meet their requirements.

React Folder Structure Architecture: Maintaining a well-organised folder structure is crucial for any React project. It helps in improving code readability, reusability, and scalability. Here's an example of a recommended folder structure:

cssCopy code

src ├─ Components ├─ Pages ├─ Services ├─ Utils ├─ Styles ├─ Assets ├─ Constants ├─ hooks └─ index.js

The components folder should contain all reusable UI components, while the pages folder can hold the main application pages. The services folder can store API service modules, and the utils folder can contain utility functions. The styles folder can include global styles or style constants. The assets folder can store static assets like images or fonts, and the constants folder can hold application-level constants. The hooks folder can contain custom React hooks.

Modular Component Design:When designing React components, it's important to follow the principle of modularity. Each component should have a single responsibility and be reusable. This helps in separating concerns and makes the code more maintainable. Components should be self-contained, with their own state and logic. Avoid tightly coupling components to prevent unintended side effects.

Use Functional Components and React Hooks: With the introduction of React Hooks, functional components have become the preferred way of writing components in React. Hooks provide a way to utilise form and other React components without writing class elements. It's recommended to use functional components with hooks as they offer better readability, performance, and code reusability.

Use Prop Types or Typescript for Type Safety: Type safety is crucial for maintaining large-scale React applications. PropTypes, a built-in type-checking feature in React, allows you to define the expected types of props that components receive. It helps catch errors and provides better documentation for component usage. Alternatively, you can also use Typescript, a statically typed superset of JavaScript, for better type safety and editor support.

Optimise Rendering and Performance:React's virtual DOM efficiently handles rendering, but there are still ways to optimise performance. Use React's memo or PureComponent to contain excessive re-renders of components. Implement shouldComponentUpdate or use the useMemo hook to memoize expensive calculations. Avoid binding functions in render methods to prevent creating new function instances on every render. Use React's Profiler API to identify performance bottlenecks.

State Management:For managing complex application states, consider using state management libraries like Redux or MobX. These libraries provide a centralised approach to managing application states, making it easier to share data between components and handle complex state transitions.

Code Splitting and Lazy Loading: Code splitting and lazy loading are essential techniques to optimise the initial load time of a React application. Use tools like Webpack or React Loadable to split your code into smaller chunks and load them on demand. This helps reduce the bundle size and improves the application's performance.

Testing: Writing tests for React components ensures code quality, prevents regressions, and helps in maintaining a reliable codebase. Use popular testing libraries like Jest and the React Testing Library to write unit tests and integration tests for your components. Aim for good test coverage to catch potential bugs and ensure the stability of your application.

Use Functional Components with Hooks: Take advantage of React v16.08's new feature, "React Hooks," to simplify the creation of functional components that interact with the state. By using hooks such as useEffect() and useState(), you can reduce the complexity of managing state in Class components. Embracing functional components with hooks allows for more frequent reasoning and state updates without the need for extensive hierarchical changes.

Enhance HTTP Authentication with Security: Authentication is a critical aspect of many applications, particularly during user login and account creation. It is essential to prioritise security in these processes, as client-side authentication and authorization can be susceptible to various security vulnerabilities that could compromise the application's integrity.

Protect Against Faulty Authentication: Occasionally, an application may crash after providing authentication information, potentially leading to unauthorised access and misuse of user credentials. It is crucial to address such vulnerabilities and implement measures to prevent them, safeguarding user data and maintaining the application's security.

Safe from DDoS attacks:Inadequate IP hiding and flaws in application state management can expose security risks and make the application susceptible to Distributed Denial of Service (DDoS) attacks. Implementing robust security measures can help mitigate these risks, ensuring that the application remains resilient and capable of handling potential service disruptions caused by malicious attacks.

Conclusion: 

Following React best practises is crucial for any React developer to build scalable, maintainable, and performant applications. From maintaining a well-organised folder structure to using functional components with hooks, type safety, and optimising performance, these practises contribute to the overall quality of your codebase.

Frequently Asked Questions

• Why is the React folder structure architecture important?

  The folder structure architecture in a React project plays a vital role in organising code, improving code readability, and enabling code reusability. It helps developers locate files easily, separates concerns, and promotes a modular approach to development. Following a well-structured folder architecture enhances collaboration and scalability within a project.

• How does ReactJS contribute to application structure?

  ReactJS provides a component-based architecture, allowing developers to build applications by composing reusable UI components. This approach promotes a clear separation of concerns, making the application structure more modular, maintainable, and scalable. With React's declarative nature and component reusability, developers can create complex applications while keeping the codebase organised and manageable.

• What are the advantages of using react hooks?

  React hooks, introduced in React 16.8, revolutionised how developers write React components. Hooks enable functional components to have state and lifecycle features, eliminating the need for class components. They offer better code readability, reusability, and testability. Hooks simplify complex component logic, encourage code modularization, and enhance performance optimisations.
