10 Best ReactJS Practices and Tips to Follow in 2023


“To bring a distinctive and cutting-edge user interface to a website, developers must follow some fundamental practices. As React is one of the most demanded libraries to create user-interface, developers should maintain well-organized code and functionality enhancement to the react-powered project to stand out their services. In this blog, we have enlisted, the 10 best ReactJS and tips that all React js development company should follow in 2023.’’

Let’s get started:

1. Keep components small and function-specific

Although React supports huge components to execute multiple tasks, it is essential to keep Components - small and function-specific. It is ideal to have a single Component to render a specific bit of your page or to modify a particular behavior.

It has many advantages:

  • The ability of function-specific components to stand alone facilitates easy testing and maintenance.
  • Each small Component can be use in multiple projects.
  • Components executing general functions can be made available to the community.
  • Performance-optimization can be applied very easily with smaller Components.
  • Small Components are simpler to update.
  • Large Components must work harder and may be more challenging to maintain.

2. Minimize the creation of new components

Stick to the rule of one function =one component. It helps to improve the reusability of components. If a Component already exists for a Function, you should skip building a new one.

Reusing components for a project or multiple projects not only leads to consistency but also helps to contribute to the community.

​​Large component is very- difficult to handle. So, it is best to divide it into as many smaller components as required.

3. Consolidate duplicate code

A common rule to keep your code clear and bug-free are - Keep your code brief and concise. The same goes for React. The most prominent way to do this is to prevent code duplication - Don’t Repeat Yourself (DRY).

Examine your code for patterns and similarities. If you find any, it might be due to code repetition. You can eliminate the duplicate code by rewriting the code, to make it more concise.

4. Comment only where necessary

Don't attach comments to a code until it is required. It is not only among the best React practices but also serves two motives at the same time. It will keep code visually clutter-free. You can prevent a potential conflict between the comment and the code if you happen to change the code at some later time.

5. Follow Naming Conventions

Always name a component in PascalCase to differentiate them from other non-component JSX files. Example NavMenu, TextField, and Success Button.

Example: handleInput() , showElement().

6. Choose Fragments Instead of Divs Where Possible

React components return code wrapped in a single Code, usually a

or a React fragment. It is recommended to choose Fragments wherever possible.

increases the DOM size, especially in big projects, as more tags or DOM nodes require more memory for your website. Due to this, more power to load your website results in lower page speed and poor user experience.


const Example =()=>{

Hello , React Js Fragment Example.



7. Organize all files related to the same component in a single Folder

Follow a component-centric approach while deciding on a project structure. It means having all the files related to the same component in a single folder.

For example- If you create a Navbar component, create a folder named navbar containing the Navbar component itself, the style sheet, and other JavaScript and asset files used in the component.

A single folder for all the files of each components makes it easy to reuse, share and debug. If you want to see how a Component works, it only requires opening a single folder,

8. Avoid Using State (If Possible)

React state maintains a record of the data , and when it changes, it causes the React component to re-render. While developing React applications, avoid using State as much as possible. The more State you use , the more data you have to keep track of your project.

One method to reduce the usage of the state is by declaring it only whenever necessary. For instance, if you are retrieving user data from an API, keep the entire user object in the state rather than just storing the individual properties.

For example :

Instead of doing this:

const [username, setusername] = useState('')
const [password, setpassword] = useState('')

Do this:

const [user, setuser] = useState({

9. Use Object Destructuring For Props

Use object destructuring to pass the prop name instead of passing the prop name. It eliminates the requirement to refer the props object each time you require to utilize it.

For example, the following is a component that uses props as is.

const Button = (props) => {
return ;

With object destructuring, you refer to the text directly.

const Button = ({text}) => {
return ;

10. Write Tests for Each React Component

Write a test for all the react components you create. It reduces the possibility of errors. Testing ensures that Components are behaving as you have expected. Jest and Cypress is one of the most common testing frameworks for React. It provides an environment where you can run your tests.


You must have reactjs in your toolkit if you are into front-end development. To create innovative, out-of-the-box, and engaging user interfaces- there are some basic react practices to follow.

We hope these 10 best ReactJS practices and tips will help you to put your project on the right track and organize your code, coding skills, and application performance. Still in doubt? Feel free to connect us at sales@tecorb.com
