Best Practices of React JS Development

by Maria Berg

Are you considering React.JS development? It’s true that the market is full with the influx of several competitors. But, there’s no doubt that reacts has always been the best framework to follow. T is easy to use, has an easy learning curve and can help your developers create the best solutions that are not only interactive but also engaging.

So, what are the best practices of React.JS that a react developer can use to improvise the way the code is? Still searching for them? We have got you covered.

Read on to discover the top react web development techniques and tips to help you be a better developer.

What Is React.JS? Definition and Usage

An open-source JavaScript programming language framework is called React.JS. With the help of this framework, programmers may design user interfaces for single-page apps that range in complexity. This technology may be used to manage the display quality of online and mobile applications. Of all the frameworks, React presently has the largest community. Make the most of open data libraries and advice from global producers to make the most of your connection with the framework.

In 2011, React made its debut in the Facebook social networking feed. With the help of this framework, programmers may build complex mobile and online applications and edit data without refreshing the page. It is a quick, easy, and expandable framework. Use it in conjunction with a variety of other libraries to develop engaging apps.

Best React.JS Development Practices

Following these practices to use React to the fullest:

Keep All Your Components Function-Specific and Small

What advantages do components offer? It is well known that the React framework enables you to access significant components that support a variety of jobs. Of course, making components small and essential is the ideal approach to designing them. In this manner, you might supply a single component to carry out a single task. You have successfully completed your design goal if a single component can render a specific section of an application page or alter its behavior.

The majority of the time, components will be entirely self-contained. That makes testing and maintenance at various phases of development considerably simpler. Additionally, it’s critical that developers simultaneously use each component in several projects. You can take parts from public forums that serve common purposes. Keep in mind that speed and update process optimization are made more straightforward the smaller the component.

As you can see, using smaller components allows you to carry out your tasks with greater freedom. More significant components will also require more room and be less flexible. Depending on the objectives and requirements of your specific project, a react developer is free to use and mix the components as you see appropriate. There are several alternatives. Therefore make use of the framework community’s knowledge.

Include CSS In JavaScript

It’s typical to retain all CSS styles in a single SCSS file throughout the first stages of project development. A global prefix can be used to eliminate any potential name conflicts. However, there are several situations in which this method is inappropriate. For instance, project scaling.

Developing a style and theme throughout the development of massive projects may be pretty tricky. The upkeep of these enormous SCSS files is a difficult chore as well, though. The idea of CSS-in-JS solutions developed as a result. These libraries are built on the following idea: Glamorous, Styled Components, and EmotionJS.

Use the libraries mentioned above in accordance with the needs of your project. For more intricate themes, for instance, you may utilize Glamorous or Styled Components.

Always Use A Linter In React.JS Development

One of the crucial steps in the creation of a project is linking, which enables you to execute a program and check the code for any mistakes.

This component is typically used by developers to address issues with the programming language. But a react developer can also use it to automatically solve other problems, including bad coding practices. You can maintain your React code free of bugs and mistakes by using the linter when writing it.

Add Comments Only When Required

It is a chance to accomplish two objectives at once and one of the framework’s best practices. Commenting should only be done when absolutely essential to further the development process. By doing so, you may prevent any potential conflicts between comments and code while still leaving visual clutter in the code. The use of comments might prevent your product from functioning properly if you plan to update the code in the future.

So keep in mind to only remark in circumstances where you are unable to do so otherwise.

Always Use Capitals For Components Names

All new component names must start with capital letters if you are using JSX for development. It’s required so that JSX can distinguish them from the standard HTML tags and handle them differently.

All inline names were fully supported by earlier versions of React. They may be distinguished from the usernames, thanks to it. This technique did have a drawback, though. Names lists were regularly updated. So when naming components, capital letters were used by convention.

You may once again utilize lowercase letters if your application is not developed in JSX. But bear in mind that this can have an impact on how parts are used in other projects.

Try To Separate Rendering From Stateful Aspects

The React framework’s components may or may not have all been specified. The state information for those components that have state tracking capabilities is stored, providing the essential context for development.

On the other side, components without states lack memory and are unable to provide other UI components context. They accept data from the parent component and provide back JSX elements. Remember that they may be scaled, reused, and are comparable to JavaScript’s pure functions.

Maintaining a separation between the rendering logic with state preservation and the rendering logic with state preservation is one of the top React best practices. In that circumstance, it is preferable to have several components with state tracking for data loading and another component without a state for information presentation. It significantly lessens the components’ complexity.

React has an additional feature called React Hooks that allows you to build components for state tracking functions in later versions of the framework. As a result, it is feasible to do away with the requirement for class-based components.

Say information is received for your project when it is rendered. You must handle the data in the primary component before passing the challenging rendering task as properties to a subcomponent.

The Code You Write Should Be Testable

The code you create for your project may be tested and verified with ease. When developing code, remember this straightforward principle. Here is one of the top response techniques, by the way. Add the extension “.test” to test files with the same name as the original file. Finding files that have previously undergone testing will be significantly simpler for developers.

To test the functionality of your React code, use tools like Cypress.io or JEST. Testers should be able to rapidly and simply test your project code and expect it to function correctly. You will run into issues with other project development phases if your code is challenging to test.

Store All Anyone Component Files In A Single Folder

A simple but crucial piece of advice is to store all files related to the same component in the same folder. Code-style files are likewise covered by this.

Keep all the smaller components in the same folder if you only utilize them within a more enormous component. The hierarchy and structure will therefore be straightforward, making it simpler to locate the necessary components. To make extracting or altering code for other projects simpler, adhere to a rigid structure and use folders inside directories.

CSS styles, pictures, tests, and other supporting components for one component should all be included in a single folder. You’ll find it simpler to locate the files later if you give the files short names and group related and similar files together logically.

Use prop Types And default Props

As your project develops, you can come into a few type-checking problems. You may utilize JavaScript programs like Flow or TypeScript for specific tasks. If you choose not to utilize them, React still offers some fundamental type checking features. Due to the vast user base of this framework, React services’ best practices are easy to uncover. You may set a unique propTypes property to make type verification for component props happen.
