4 Common Mistakes to Avoid When Developing with React JS

React is one of the best JS advancements. But, with the growing popularity of the tech stack, there are a lot of snags faced by the developers who are now working with Reactjs. So, avoid these mistakes if you are about to use the ReactJS development services.

To ensure that your SDLC turns out to be great, you must look at these common issues that might occur during the process. This blog will help you improve the best possible amendments you can make while working with React for faster and better results. 

For those who are about to lead a team for a Reactjs project, this article will help them avoid React mistakes and deploy their app on time.

Of course, React is a great choice, but every great technology has loopholes. AI, too, has some drawbacks, so you have to be careful while using the JS advancement. So, before avoiding mistakes, let's understand why React should be your first choice to develop a web app.

Why choose ReactJS?

40.58% of experts across the globe have been swearing on Reactjs development services. React's success can be attributed to its many advantages, particularly in building web applications.

Here are three reasons businesses choose React to create reliable web solutions:

• Speed: The reusability of components on the client and server side helps to ace the SDLC speed. As a result, one can add new features and create separate parts without changing the logic of the overall solution. This saves an expert a lot of time during the development phase.
• Adaptability: React code is simple to update. Because of its versatile modular structure, it helps firms save time and money. Also, the tech is flexible and blends in well with other JS advances.
• Performance: Server-side rendering and a virtual DOM are the core offerings of the React framework. These advantages can be used to speed up the execution of complex solutions.

Another strong point for React is its ever-growing & active online community. They help the Reactjs stack intact with time and help experts accelerate their SDLCs. Also, the JS tech has never missed to Wooh! The audience by its extensive deliverables of packages, tools, and react chart libraries for a modern web app.

After knowing its core benefits, let's consider the challenges of building a web app with React.

Common Issues to Avoid While Developing SDLC With React.JS

1. Functioning with props

The core of a React framework is its components. These contain logic that helps an element to interact. For instance, elements like buttons and input boxes function after

receiving sound logic. On the other hand, props help pass data from one component to another and work as an argument for intriguing details like usernames.   

Common mistakes to avoid while using props

Prop passing to child component without any use

An expert must pass some logic to the child component without using props. This could happen for any reason, like an unused pile up of props or a challenge in creating a code. If there is a piling of props, then it becomes hard for other users to read. As a result, every time your team examines the current code, more time will be required. It's also advisable to avoid writing unnecessary code in the first place because it can result in erratic problems that are challenging to fix.

How to fix it?

• You need to review props up close.
• Do not pass a component or prop you will not use.

Passing of ref and key as a prop to the component

The one with years of knowledge in React would know this. Key and ref are never used as props. However, it can slip from an expert's mind and cause a grave error.

How to fix it?

• Refrain yourself from passing ref or key to a component.
• Use forwarder or rename the prop.

Props drilling

In this situation, an expert passes the same set of components one level down from its parent to the said component at the end. Thus, ensure to add a prop to avoid connecting components. The fewer interconnections of components will result in a better code.

How to fix it?

• Use libraries like Redux or MobX to avoid such drilling.
• You can also use createContext API & useContext hook.

These were the three significant mishaps in component and prop usage. Now, let's move on to the next challenge.

2. Use of the useState hook

React hook is all about adding variables to your component. In React, the state is data that can be used in the apps. The useState is all about creating, tracking, and updating a state in functional components. Now, using such a hook is tricky, so let's get into the mistakes that one might get into while using it.

Common mistakes to avoid while working with useState hook

• Avoid extensive use of useState hook.
• Avoid the use of more than oneuseState hooks for a single entity.
• You should not forget that it is asynchronous.
• Do not miss out on the useState hook.

How to fix it?

When in doubt, always check the official guidelines of React documentation.

3 Use of useEffect hook

In functional React components, side effects are managed with the useEffect hook. Here are a few instances of adverse effects:

• Fetching details
• Direct updation of DOM
• Using time feature

UseEffect deals with these side effects with ease in otherwise pure React components.

Let's now examine three frequent errors made by React developers while utilizing the useEffect hook.

• Inefficient use of useEffect hook
• Infinite loop creation with useEffect hook
• Not using the cleanup function

How to fix it?

• Ensure the useEffect hook is used when necessary.
• Control dependencies array
• Remember to cancel useEffect to prevent any adverse effects.

4 Issues with JSX

The syntax for any markup that React renders in the app is built on JavaScript XML (JSX). It can help an expert out with errors and warning messages all with the help of JSX, which also makes writing React apps easier.

Two common errors made by React developers while utilizing JSX to create applications are as follows:

• Usage of a large anonymous function
• Overuse of embedded expressions

How to fix it?

• Avoid the use of large anonymous functions
• Build separate functions and keep your code clean
• Avoid overuse of embedded expressions to maintain good code readability

On a concluding note!

React is one of the best and most admired JS frameworks. But, still, one needs to be extra careful while using the advancement. All these technical details will help you build a more efficient SDLC.

An expert must be extra careful and build a reliable solution with a real-time deployment facility. So, avoid these common mistakes for a flawless ReactJS development project.
