ReactJS Best Practices - How to Make React Code Cleaner and Error Free

  Arena Kelly    March 3, 2022    86


React is a component-based framework for creating highly interactive user interfaces that is simple to use and declarative. To make the app development process shorter and smoother, developers must adhere to best React practices to take full advantage of the technologies and maintain code clean and structured. To leverage its best performance, there are some basic standards to follow when coding an app with React.

Best Practices for React Js

Some of the most highly recommended React best practices are listed here.

Components Should Be Compact And Function-Specific

As we all know, React allows us to create large components that perform several jobs. However, keeping components minimal to address a single purpose is a superior method to design React applications. In an ideal world, a single component would render a specific area of your website/app or modify a certain behavior. There are several benefits attached to this:

●     Function-specific components may be used independently, making testing and maintenance more convenient.

●     Each little component can be utilized in several different projects.

●     Create components that are open to the public and perform general operations.

●     Performance enhancements are easier to apply with smaller components.

●     It's easier to update smaller components.

●     Larger components are more difficult to maintain

The balance between developing one compact component and multiple function-specific components may change from one organization to the next. After all, you may use as many components as you want and recombine them in whatever way you choose to get the same result.

Indexes Should Not Be Used As A Key Property

According to expert React developers, key props assist React in determining which item has been updated, added, or deleted. The key should be assigned to the element inside the array to provide the elements with a stable identity.

Because React doesn't waste time re-rendering duplicates, it leverages key props to determine what to render or re-render. When two items have the same key, the React will omit one of them.

Another thing to consider is that React re-renders elements whose key has changed for a certain element's content, even if the content hasn't changed.

Make Use Of The Built-In Props And Prop Types

In JavaScript, you can't specify a variable or argument type. As a result, there's a potential that the variable type will be misinterpreted.

Furthermore, JavaScript does not enable you to indicate which attributes are necessary and optional in React, nor does it allow you to add default properties to objects or components. If you neglect to assign a property to a needed object or component, you'll have a problem.

Prop type and default props can fix both of the problems mentioned. It also helps in improving the quality of your code, making testing and debugging considerably safer and faster.

When It Comes To Initial State Components, Avoid Using Prop

The "source of truth" is frequently duplicated when props are used to build the initial state component; the "source of truth" is frequently duplicated. Getting an initial state is only called once when the components are first constructed.

When you make changes to the props on the component again, the prior value will not be updated; therefore, the component will remain unaltered. Avoiding the use of props in the initial state can address the problem.

Dividing Bigger Components Into Smaller Ones Is A Good Idea

Break the main component into smaller ones to make it reusable. The approach is known as the "single responsibility principle," which states that instead of placing many features in one component, construct one component accountable for a single functionality.

Separating components will make it easier to understand, maintain, debug, reuse, and scale code in the long run, as the project continues to grow in size as new features are added.

Remove Stateful Elements From The Rendering Process

React Components can be stateful or stateless. Stateful components maintain track of changing data, whereas stateless components render the same data every time.

Isolating your stateful data-loading logic from the rendering stateless code is always a smart idea to reduce component complexity.

Summing Up

We've gone through the best practices for React developers to follow to write clean code and make code maintenance & testing easier.

We hope that by following these best practices, you will develop a clean and well-organized React app and prevent any long-term troubles.
