What Are the Top React Development Practices?

When we talk of the front-end development software, React stands as a front-runner in the toolkit list. The React library allows the developers to perform seamless integrations and design their components.

While creating React-based web solutions, it is important for the developers to adhere to the best React practices. Here are some of the top practices that will help you create organised code:

Create small function-oriented components: React allows you to build big components that help you run multiple tasks. However, it is recommended to create small components that represent one function/behaviour.

Benefits of creating small components:

• Easy to reuse small components

• Perform performance optimizations

• Quick updates

• Easy testing and maintenance

Dry Code: Coding standards define to keep code short and concise. You can achieve this by implementing the DRY approach. Dry means Don’t Repeat Yourself. This is one of the easiest ways to reduce code duplication.

Examine the code for similarities. If you find any repeated iterations, delete them. For instance: Use the IconButton component to create buttons rather than including markup for different buttons.

Limit Comments: Mention comments to the code only when required. This helps you keep your code clean. Also, in case you need to change the code, you’ll stay away from the code and comment clash.

Include CSS in JavaScript: Generally, when developers create project using the React App Builder, they keep the CSS style in one SCSS file. But, as the project becomes bigger, this approach doesn’t work ideally. Therefore all the CSS code should be included in JavaScript. Use Glamorous and EmotionJS (CSS in JS Libraries) to do so.

Name the component after function: Always name the component after the function it runs to make it noticeable. For instance: ProductTable – Reveals the role of the component. Also, naming the component makes it discoverable to the community.

Name the component in uppercase: Always use capital letters to name the components. Make it a norm to capitalise the components such as SelectButton and Menu.

Locate all related files in one folder: Files related to a component should be placed in one folder. For example: When you create the Form component, include all the files such as icons, images, CSS files, and mini-components in the same folder. Name all files logically and you will be able to locate them easily whenever you need them.

Obey the Linting Rules: Linting is an automated process that helps you find programmatic errors. Use linter in your React program to reduce the bugs in your code.

Distinguish stateful logics from stateless logics: React components are either stateless or stateful.

Stateful components contain the details of the state of the component and store relevant context. However, the stateless components don’t provide context. They take inputs from the parent component and give back JSX elements.

Separate the stateful components from the stateless components. Stateful components load data while stateless components show data lowering the component complexity level.

Testable Code: The code should be testable. The test files should have the same name as the source files followed by a .test extension. This makes locating test files easier.

JEST (JavaScript testing framework) is an ideal framework to test React.
