How to create components in ReactJS?
Do you have any idea about React JS components? If you want to gather all the necessary details regarding such a topic, go through this blog. In general, React JS components are the major part of the UI (User Interfaces) in various web applications.
It consists of functional & presentation characteristics in self-contained and reusable components. Professional developers can easily maintain and reuse their code by dividing challenging UI into more manageable, smaller pieces using components.
React JS components can be either functional or class-based. Functional components use JavaScript functions, and class-based components use the ES6 classes to render user interface elements.
The components will receive the proper inputs to enable data exchange and customization between different components. React JS components enhance development productivity and increase creative, interactive, and dynamic UI ability. You can hire reactjs development company for your project and grab extraordinary benefits.
Impact of react components:
React components are the fundamental part of the React application. The code-encapsulated and small units can build UI across the complete program. The user interface of this program is divided into modular and smaller components. It lets developers build very effective, user-friendly apps.
The react component takes care of its state & events while producing a specific part of the UI. The standalone component can receive data, process it & output the react element without any issues.
Different types of react JS components:
Two different types of React JS components are available: functional & class components. Some additional components are found, such as composing components, rendering components, react & decomposing components.
-
Function components
Functional components are the primary type of the React JS component. It is a JavaScript function that receives the input properties and will effectively return the react element.
The functional components are said to be stateless since there is no internal state. The functional components are responsible for rendering the UI using the input properties.
-
Class components
Compared to the class components, the function components are very simple with ReactJS. It will extend the react. The class components are built using the ES6 classes. It can manage complex logic and handle events since they have its internal state and lifecycle methods. There are some essential features you can explore in class components.
Such features are:
- State
- Lifecycle Methods
- Props
- Class Methods
- Event handlers
- Render Method
Additional components:
-
Render component react
The render component react has a better user interface. Components are the building blocks of various react applications with independent and reusable user interface elements.
When the component begins to render, it will be instantiated & displayed on the screen. The virtual DOM (Document Object Model) is the actual DOM used by React. React can update & re-render the relevant components when the props or state changes.
-
Composition in react
A composition in React can combine & nest reusable, smaller components into the bigger ones to create a highly sophisticated UI. It is possible to design the UI in a scalable and modular way. There are many advantages available in this additional component.
Such advantages are:
- Composition in react can increase the code re-usage
- Can easily maintain the code as a result
- Can extend the code easily as the result
The major advantage of composition in React is that it is useful for developers.
-
Decomposing components
The decomposing components are one of the additional types of react components that can divide the challenging components into reusable and smaller components. There are many advantages available in this additional component.
Such advantages are:
- Readability
- Reusability
- Maintainability
It is the primary advantage of decomposing components that are useful for developers.
Nesting react components:
The strong point of react is its ability to place the component into other components. It lets professional developers perfectly organize the components into a hierarchical structure.
Here, each component can generate a particular area of the UI – User Interface. Each component will be written & tested separately without creating issues for the other components. Such component layering will encourage code reuse & maintainability.
React components lifecycle:
The react component will go through a lifecycle comprising many stages or phases from the document object model from the creation to the removal process. Users can use such lifecycle methods to perform specific essential tasks like initializing the state, depleting resources or obtaining data in the component’s lifecycle.
There are certain primary lifecycle steps one can explore with the class component. Such steps are:
- componentDidMount()
- constructor()
- componentDidUpdate(prevProps, prevState)
- shouldComponentUpdate(nextProps, nextState)
- componentWillUnmount()
It is a must to understand the component’s lifecycle to handle asynchronous activities and manage state & critical performance in react applications.
Best practices and principles of react JS components:
The React JS components are a fundamental part of modern website development. It will let programmers and developers design better modular, maintainable and reusable UI. The class components are the effective type of react components that provide extraordinary abilities like lifecycle methods and state management.
The functional components are also other types of react components that create a better way to render the user interface based on props. The nesting of components and component lifecycle lets developers easily develop complex applications. To master react programming, following the best practices and principles of react components is best.
Such best practices are:
- Reusable & Composable
- Single Responsibility
- Functional Components
- Props validation
- State Management
- Component Lifecycle & Side Effects
- CSS & Styling
- Immutability
- Consistent Naming & Code Organization
- Testing
- Documentation & Comments
The above mentioned are the best practices of React JS components.
Conclusion:
You now have the idea of React JS components from the above-mentioned scenario. Get ready to hire react js developer and execute the process very quickly. You can certainly benefit from this process. It is effectively possible to build different applications with the help of React JS components. Hence, focus on this component and grab many exclusive impacts.
