Top 13 ReactJS Best Practices and Tips to Follow

As the world wide web is moving in a steadfast direction, developers must remain constantly updated with the new processes. While development updates and new technologies have challenged and formulated a race against time, developers ought to be flexible and up-to-date.

Constant innovations and advances have increased the utility with smartphones and mobile applications available for all and any purpose. In the present scenario, technology even enables delivering grocery or other daily goods right at the doorstep. Making the world a smaller place to live in, these technologies have enhanced human experiences.

Hence, with increasing demands, developers seek options for technologies that are easy to use, provide easy deployment, facilitate, and deliver better application performances for seamless experiences. Thus, with many new technologies making a buzz, a new and most user-friendly technology added to the basket is React.

React created as a JavaScript library that allows integration with many exciting components. Interestingly, React as a library also allows developers to create their own components and share them with other developers. As UI (user interface) is an integral ingredient in app development, React is useful for UI developers determining enhanced user experiences and efficacy. Thus, React is useful for creating exceptional UI, leveraging complex UI to component-based UI. It further allows developers to utilize the small UI components for development to React Native iOS and Android applications.

As we discuss the advantages of React, now let’s check some of the most fundamental React best practices to follow in 2022:

1. One component = one function:

As React allows you to create huge components with various functions, it is always recommended to create small components with a specific function. As an advantage, small components are easier to maintain and test. They can be reused across different projects. Developers with small React component best practices can be updated conveniently and also efficiently implement performance optimizations.

2. Reuse the components:

Building one component for one function can help developers increase the reusability of the component. Also, building a new component specific to a function can avoid creating components again and again. Developers should also avoid building new components that are already present. Thus, reutilizing the same components across stages in a product or different projects can build consistency. Developers can also create and share the component with the community.

3. React’s Context API through a Higher-Order Component:

React provides content API in the exchange of information and then passing it to some other parent component. The solution for this problem is to combine the context API higher-order-components to avoid passing props. HOC is a technique to reuse the component logic and a function in the returns a new component.

4. Do not duplicate codes:

While duplicating codes and repeating them is always a concern, it is always advised to keep the codes brief and concise. Thus, it is no different to React to. Hence, one of the best React practices is also to keep the code precise and short. Do not repeat the codes. Instead, developers can examine the codes and look for patterns and parallels. Developers should eliminate any such repeated codes and alternatively rewrite a few codes to make it brief.

5. Name your component and maintain the folder:

To easily recognize and use components optimally, developers should name the components accurately. Naming components basis their functionality and use can be effective; rather, naming components basis their need can be confusing. Along with, name your components starting with uppercase letters. As the earlier React versions maintained a list of build-in names to differentiate from custom names, the previous versions were scrapped and now follow the norm of Capital letters.

Significantly, developers using the JavaScript extension (JSX) can create components and name them with the first letter in uppercase. As an advantage, JSX can then identify them easily from the default HTML tags.

It is equally important for developers to store all files in a single folder. While using smaller components, it is easier and logical to maintain all smaller components together within one component folder. This provides developers with the ability to extract and modify codes when required for any other project too. Thus, as one of the best React practices, this enables to develop a systematic process where large components are in their own folders, and smaller components are maintained in sub-folders for utility.

6. Components- stateful and stateless from Rendering:

React components can be stateful or stateless. However, as a best ReactJS tricks, developers should keep the one stateful component to load data with data-loading logic and separate them from the stateless rendering logic, maintaining a stateless component to only display the data. This will, in return, reduce the complexities. Further, leveraging on React versions like v16.8, react offers react hooks that write the stateful function-related component, eliminating the need for class-based components.

7. Use tools:

As a best practice, React allows us to organize all React components with the use of tools like Bit. Thus, this React practice allows us to maintain and reuse codes. It also supports code to become discoverable and promote team collaboration to build components and sync the codes across projects.

8. Use linting rules:

Linting is a process that is used for language-related issues where developers can run programs and analyze codes for errors. Thus, using linting as a React practice can support developers to maintain codes and relatively minimize errors and bugs.

9. Use snippet libraries:

An important React practice, code snippets, keep the most recent syntax. As such, for developers, snippets can further support to keep codes bug free and should be considered as a significant React practice. Some of the snippet libraries that developers can use include- JS Snippets, Redux, and others.

10. Use JEST:

As codes are integral, it is important that they can be tested easily and quickly. Thus, one of the best practices is to name the test files identical to the source files. To differentiate, developers can include a .test as a suffix so they can be located easily. For React codes, developers can efficiently test codes using JEST.

11. Comment only where necessary:

It is always recommended to add comments in codes only where required. As one of the best React practices, it also further supports maintaining codes clutter-free and avoid any kind of conflict between the comment and codes.

12. The Anticipation of Lazy Loading:

To optimize the loading time, lazy loading provides a solution to delay any specific object, when it is required. In ReactJS, the information is rendered, and then it is wrapped for the non-critical items later. Usually, it is beneficial in terms of bandwidth and loading time to deliver the content when user requests for a specific page, so it is advisable to get lazy for React.

13. Follow linting rules:

Linting is a process to analyses code to identify potential errors. Our experts are using it to identify language-related issues, and it is also beneficial in terms of fixing many other issues, specifically like code style. Following the linting rules to keep your code error- and bug-free.
