When building a ReactJS application, it is important to keep your components small and reusable. Large, monolithic components can be difficult to understand and maintain, and can make it difficult to update or change individual parts of the feature. Instead, by creating small, reusable components, it becomes easier to understand the functionality of each component and how they fit together to create a larger feature.
Creating small, reusable components also allows for better code organization, making it easier to find and update specific parts of the application. Additionally, reusable components can also be used across multiple features in the application, reducing development time and making it easier to maintain the application as a whole.
An example of creating small, reusable components is building a navigation bar. Instead of creating one large monolithic component that handles all the navigation functionality, you can break it down into smaller, reusable components such as a Navbar component, a NavbarBrand component, and a NavbarItem component.
<Navbar>
<NavbarBrand>My App</NavbarBrand>
<NavbarItem href="#">Home</NavbarItem>
<NavbarItem href="#">About</NavbarItem>
<NavbarItem href="#">Contact</NavbarItem>
</Navbar>This way, each component handles a specific piece of functionality, and can be easily updated or changed without affecting the rest of the navigation bar. Additionally, these smaller components can be reused in other parts of the application, such as a sidebar or a footer.
Another example is creating a reusable button component. Instead of creating a new button component for every action in your application, you can create a reusable Button component that can be used throughout the application.
<Button onClick={() => alert("clicked")}>Click me</Button>This way, you can maintain consistency in the design and behavior of buttons throughout the application, and any updates or changes to the Button component will be reflected across the entire application.
In conclusion, keeping your components small and reusable is an important best practice in ReactJS development. Large, monolithic components can be difficult to understand and maintain, and can make it difficult to update or change individual parts of the feature. Instead, by creating small, reusable components, it becomes easier to understand the functionality of each component and how they fit together to create a larger feature. It also makes it easier to maintain and update the application in the future. By following this best practice, you can help ensure that your ReactJS application is maintainable and scalable.
