Use the right development practices by following these 12 dos & don’ts for creating a successful React JS project.

React JS is undoubtedly one of the most successful front-end development frameworks available for use today. With the rich JavaScript library, cross-platform support, and UI-focused dependencies, React can help build dynamic web experiences for businesses.

Despite having many advantages, you can’t ignore the fact that it is pretty unopinionated about how one should structure the code, unlike other technologies.

Therefore, the chances of mistakes shift from low to very high. In any case, adopting good development practices is a must for React developers and businesses too should have knowledge about the same.

Here, these do’s and don’ts of successful React JS development are likely to help both developers as well as businesses.

These practices can not only boost the development skills of a React JS developer but can also help businesses make informed decisions when they hire dedicated ReactJS developers.


Follow A Streamlined Folder Structure

Follow A Streamlined Folder Structure

You open a book and go to the desired chapter just by browsing the index page; Your code should be as sorted as a book’s content.

Creating a folder structure can help you achieve this level of perfection.

And if you have plans to build a large application, this is an essential step. You can ask React Js developers to arrange different modules for your apps and keep the codes in one place.

It comes in handy when you want to reuse them or remove them for that matter.

In fact, even if you have a change in developer or development team, the next person who comes in gets their hands on a well-structured code and can understand or manage it.

Other benefits of this practice are –

  • Since all the modules are isolated, if you encounter an error in any of the modules, you won’t need to change the complete app.
  • It’s easy to maintain.
  • Implementing lazy loading becomes easier as all the modules are arranged separately.

Encrypt Your Data For Security

Encrypt Your Data For Security

Did you know that about 70% of system intrusion security breach involves attacks caused by malware? And about 32% of such malware was distributed via the web.

Thus, securing your website or web applications is a priority.

When you hire ReactJs developers, you can ask them to focus on encrypting sensitive and confidential data such as user information, client data, JWT tokens, etc.

Nowadays people are more concerned and aware of their privacy and security on a web portal. And if your data isn’t encrypted and secure, they might abandon your portal just as well.



In a typical programming paradigm, all the coding for visual elements is done in a CSS file to avoid any confusion regarding naming and the entire thing is in one place.

As the application scales and more codes are added to the file, it can eventually lead to many problems.

To avoid this problem, developers can use CSS in Javascript with the help of unique libraries like Emotion JS, Styled Components, and Glamorous.

Inherit The PascalCase While Naming Components

Inherit The PascalCase While Naming Components

Naming is a critical aspect of any coding facility not just React. You need to pay special attention to avoid any confusion. And since React uses JSX, there are chances that your custom component names may end up matching with HTML tags.

Even though developers have a list of these tags to avoid such practices, it is best to utilize the Pascal or upper camel case in this regard.

All you have to do is start the component name with an uppercase letter. For instance, if you want to name your component as ‘menu’, you can write it as ‘Menu’.

Take The Help of Object Literals

Take The Help of Object Literals

It is a way to make your code more readable. For instance, you need to fetch details of three different users based on their role, object literals can help here.

Use Memo

Use Memo

Using Memo in React JS can enhance the performance of your application to a greater extent. It ensures no unnecessary rendering is allowed for the code.


Do Not Make Components At The Drop of A Hat

Do Not Make Components At The Drop of A Hat

We don’t want you to completely ditch the practice of creating components, but we want to see you reuse already-made components. It saves time, is consistent, and makes coding a lot easier and more efficient.

For instance, if you create a function named ‘Play’, you can create a corresponding function and reuse it at a later point in time.

This practice is especially useful when you have to write lengthy pieces of code as you can divide the code into numerous smaller components instead of creating.

Don’t Clutter Your Code With Comments

Don't Clutter Your Code With Comments

While comments are a great feature that can help anyone understand what the code is all about, they may sometimes clutter the code.

It is especially difficult when one needs to change the code as they have the hassle of editing comments too. Thus, it is best to keep it relevant.

Do Not Repeat Your Code

Do Not Repeat Your Code

This is as simple as it gets. Check your code and see that you don’t have any repeated or duplicate codes. In case you do, delete the repeated ones. However, you need to cover up the deleted part by rewriting the components.

To ensure your application is built smoothly, you can choose to hire offshore ReactJs developers and get the job done.

Don’t Pass ClassNames And Style For Your Components

When you pass ClassName and style for your components, it indicates –

  • You need to think about what style you require for them.
  • It is necessary to have information about the default styles.
  • Adding just any can break your UI.

Don’t Obsess With Render Count

Yes, it is a great practice to keep your renderings to a minimum but that shouldn’t be all you have in your app. If it is affecting the usability of your application in any manner, try not to obsess over the render count.

Not Using PropTypes Is A Mistake

No Using PropTypes Is A Mistake

PropTypes are an excellent way for compilers to know which type of data is valid for a component. Using it can save you from potential errors and you can type-check your components.

These are some of the dos and don’ts we found suitable that every React JS developer must bring into practice.

Make sure to bring this to use at the time of development or check if the candidate has knowledge about these when you hire dedicated ReactJs developers for the project.
