8 REACTJS BEST PRACTICES TO FOLLOW IN YEAR 2021
Here are some of the ReactJs best practices any frontend developer who can follow -
As per the rule, one function means one component, so one can definitely improve the component’s reusability. This means that the developer must skip trying to create a new component for a function, especially when there is a component present for that particular function. Instead, the developer must resume the components across the project or across multiple projects, to achieve consistency and to contribute to the ReactJs community.
Besides this, if the developer thinks that any particular component has become huge and it is becoming difficult to maintain it, then the app developer must break it up into required smaller components. For instance, the development team can go further and create a Button component that has the capability to handle icons. Then, each time they need a button, they will have a component to use. This proves that by creating more modular, the team will be able to cover many different cases with the same piece of coding. So, the developer needs to aim somewhere in the middle to get a component that can be used in multiple places and it must be abstract enough, but not overly complex.
2. Small & Function-specific Components
React is a technology that makes it possible to have huge components that have the capability to execute various tasks. But the best way one can design a component is to keep them small so each of these components corresponds to one function. Basically, one component must render a specific part of the page or modify its particular nature. So, the balance between creating multi-function-specific components and creating one concise component can be different from company to company. All and all, a company can have multiple components and recombine them to achieve the expected result.
4. Consolidate Duplicate Code
One of the most common rules of code that every developer keeps in mind is to brief and concise it as possible. It is the same with ReactJS technology. Here also the developers need to keep the code precise and brief. One way to avoid code duplication is Don’t Repeat Yourself (DRY). This approach can be achieved by any ReactJs developer by scrutinizing the code for similarities and patterns. The developer can definitely rewrite the code to make it more concise. But this completely depends on the reusability principle in ReactJs. For instance, if the ReactJs developer wants to add multiple buttons that come with icons, they can simply use a component IconButton called instead of adding the markup to each and every button.
5. Component Name After the Function
Naming the component after the function is one of the best ideas. It helps the developers easily recognize the components. For instance, ProductTable is a name that clearly specifies what the component does. This is important as if the developer names the component on the basis of the code, then it can create confusion in the future. For instance, it is advisable to give the component Avatar name for users, authors, or in comments. Instead, if the developers name it AuthorAvatar in the context then he would be limiting the utility of that particular component.
6. Isolate Stateful Components for Rendering
7. Component Names must be in Capitals
8. Single Folder for Similar Component Files
Keeping all files related to anyone component in one folder with the styling files is necessary. When there is a small component used by a particular component, then it means that the smaller components must be kept together in one folder. This is the hierarchy that must be followed to make the understanding of ReactJs components. Besides this, the large components of the ReactJs have their own folder and all the smaller parts of those large components are divided into sub-folders. By doing so, the developers can easily extract code to any other project or can even modify the code when it is required. For example, in the Form component, there are different pieces like icons, texts, images, CSS files, and any other sub-components that are related to the Form component must reside in the same folder.
As seen in this blog, when the developers follow the best practices of ReactJs, developing the most unique and user-friendly applications. These practices can help the ReactJs development companies to put their projects on the right track and eliminate any potential problems that can occur in the future development process. Therefore, following such practices can be very beneficial.
