For using React and leveraging the benefits it has to offer up to its maximum potential. There are certain practices advised to be followed while developing an application using React.js. We have covered some of them here, which would also help developers in evading major challenges faced while developing. Whether you are a developer using React or you want to hire React developer to create an application for your business, knowing the best practices to follow is beneficial. Since it ensures the quality, performance, security, and scalability of the application.
The practice of keeping small components, specific to function is a recommended practice than keeping large components that perform multiple functions. The advantage of having a functional component is it is standalone which makes testing and maintenance easier. The reusability of the function component is higher since it can be used in other projects as well. The readability of the code and management is also better with functional components.
High Order Components let you reuse the logic in multiple components. HOC is one of the advanced techniques used in React that avoids the repetition of code and increases code readability.
One of the best practices followed by React to avoid code duplication is to write DRY (Don’t Repeat Yourself) code. The repetitive code can be composed in a component and the component can be used multiple time to saving time and increasing the efficiency of the code.
The folder structure of the project would depend on the development team, but certain standards help us maintain a neat folder structure. A good folder structure saves a lot of time and is easier to navigate through the files. A well-organized folder structure comes in handy especially when the size of the application is large. The two common practices for folder organizing are,
Various other ways are adapted for organizing folders, it is important to follow anyone throughout the project.
Following a standard naming convention is necessary to avoid confusion later on. There are certain naming conventions followed, and we have mentioned some of them.
The component names are usually in Pascal’s case such as SelectButton, NavMenu, and TextField.
For naming methods, functions, hooks, variables, and arrays Camel case is followed for example ‘showText()’, ‘getStudent()’.
It is beneficial where the application is large and it causes delays in loading the pages. This technique helps in providing a better user experience by restricting the not-so-necessary part of the page and loading the important functionality of the page faster. It is also known as code splitting as you split the code into parts depending on the requirement.
One of the crucial aspects of development is testing to ensure proper error-free functioning. It is an essential practice to write test cases for each component you built, to write maintainable code. It is also beneficial when you are trying to add new functionality and new to write new code. Since testing ensures the existing codes work properly without error. Jest is one of the commonly used testing frameworks.
Using snippet libraries helps the developers with coding, by providing prebuilt code that can be useful in saving time and effort. Snippet library also helps you with the latest syntax. It is easier and faster to create react functional components with the snippet.
One of the major benefits of React is code reusability. By following the practice of one component, one function one can take maximum advantage of code reusability. Since you can use the component for performing the function as many times in the code as required. This practice saves a lot of time and increases efficiency, and the time to market is also reduced.
It is advisable to use object destructuring to pass the prop name rather than passing the props object. Destructuring props increases the code readability by making the code cleaner. This feature makes it easier to extract form data and the process of assigning your variables from the object.
In React, State is a built-in object that stores information or data about the component. The component re-renders whenever the state changes. Using the State is not one of the best practices, it is advised to avoid using the state as much as possible. Because it increases the amount of data that needs to be tracked across the application.
Hooks is one of the recent addition to React. With the help of Hook, you can use class and other react features without writing a class. Clean code, logic reusability, and maintainability are the major benefits of using the hook.
It is recommended to use fragment instead of Divs, the reason being fragments are faster and uses less memory compared to divs. DOM size increases when <div> is used, more memory is required which makes the application slower and affects the performance too.
We have discussed the best practices that are implemented while working with React, which makes it even more efficient and easier. While developing an application with React for your business, follow these practices and develop a high-performing application. We have an experienced team who can help you with your requirements.
