8 React Best Practices to Implement in 2023

Facebook’s Reactjs is a popular front-end library. Reactjs, on the other hand, doesn’t care how you create Reactjs applications. However, to maintain our applications clean, safe, and scalable, we must adhere to several Reactjs best practices.

There is no method to accelerate react development in sprints as React.js grows. Why waste time coding the most basic aspects when you might be working on more difficult, intricate problems? This is where we step in. We will present some of React best practices offered by some of the greatest React.js developers in this post.

Best React Practices to Follow in 2023

Because Reusability Is Vital, Limit The Number of New Components Created To a Bare Minimum

You may increase component reusability by adhering to the notion of one function = one component. This implies that if a component for a function already exists, you should avoid attempting to create a new component for that function.

By reusing components across several projects, you will not only get consistency, but you will also be contributing to the community.

On the other hand, if a component becomes too large, bulky, or difficult to maintain, it is best to divide it into as many smaller components as necessary.

CSS Implementation In JS

When it comes to huge projects, style and theming are one of the most basic React best practices. However, it turns out to be a difficult effort, similar to maintaining those large CSS files. As a result, CSS-in-JS solutions entered the picture. You may choose from a variety of libraries depending on your needs, such as those for complex subjects.

Make Use Of a Linter

A linter simply analyzes the JavaScript code you’re creating and alerts you to mistakes that you’d more likely see if you run the code.

ESLint is fully preset when you use create-react-app, but you can also build it up entirely on your own or extend the rules of a pre-built ruleset.

Maintain DRY Code

preserving your code DRY is a basic programming notion that is not confined to Reactjs. However, it is critical not to duplicate code. If you find yourself repeating code, separate the logic and functionality to create a function.

The same can be said for React components. For example, suppose you need to utilize a button in your react app many times. Make the button generic so that it may be used as needed.

Include Test Cases In Your Program

As we all know, no app is ready for distribution unless it has been completely tested, hence testing is critical in app development. To ensure that the component is displayed as expected, unit testing, snapshot testing, and Enzyme may be used.

Don’t Use “State” (If Possible)

React state stores data that, when modified, causes the React component to re-render. Avoid utilizing state as much as possible when designing React apps since the more state you use, the more data you have to keep track of throughout your project.

One technique to reduce the usage of the state is to declare it only when required. For example, if you are retrieving user data from an API, instead of keeping individual attributes, save the whole user object in the state.

All Files On a Single Component Should Be Kept In a Single Folder

If a tiny component is only utilized by one component, it makes logical to keep these smaller components all together under one component folder. The structure will then be clear: major components have their folder, and their lesser elements are separated into sub-folders. In this manner, you can quickly copy code to another project or edit it anytime you want.

Naming The Component After The Function

Naming the component is regarded as excellent practice, and it should be able to explain what the component performs promptly. Naming the component depending on the necessity for the code will lead to confusion in the future. Avatar is a component that may be used anywhere. It will be very beneficial to writers, users, and commenters. So, let us look for the distinction. However, the difficulty in this scenario will be that it may restrict the usability of that component. Naming a component after a function will be beneficial to the community.


Building React apps at scale seem to be a difficult undertaking that needs careful consideration of the best selection for the web developers. The best React practice is the one that is related to the users and your team.


Experiment with different tools and strategies for growing React applications. That will make it easy for you to proceed with the react code.
