Widget

Building a widget in frontend with a separate UI component involves creating modular, reusable pieces of user interface that can be easily integrated into various parts of your application. Here’s a guide on how to approach this:

Widget Structure

A widget typically consists of two main parts:

  1. UI Component: The visual representation of the widget.
  2. Container Component: Handles data fetching, state management, and business logic.

Creating the UI Component

  1. Keep it simple and focused:
    • Design the UI component to be as small and simple as possible.
    • Focus on a single, specific function or piece of the interface.
  2. Make it reusable:
    • Use props to pass in data and callbacks.
    • Avoid hardcoding any data or functionality.
  3. Implement the visual elements:
    • Use HTML and CSS to create the structure and style.
    • Ensure the component is responsive and accessible.

Developing the Container Component

  1. Handle data management:
    • Fetch required data from APIs or other sources.
    • Manage local state if necessary.
  2. Implement business logic:
    • Process data before passing it to the UI component.
    • Handle user interactions and events.
  3. Pass data to UI component:
    • Use props to send data and callbacks to the UI component.

Best Practices

  1. Separation of concerns: Keep the UI and logic separate for better maintainability[1].

  2. Prop types: Use prop types (in React) or similar type checking to ensure correct data is passed to the UI component[2].

  3. Modular design: Design your widget to be as modular as possible, allowing for easy integration and reuse[5].

  4. Consistent naming: Use clear, consistent naming conventions for your components and props[3].

  5. Documentation: Provide clear documentation on how to use and integrate the widget[5].

Example Implementation

Here’s a basic example of how you might structure a widget with separate UI and container components:

// UIComponent.js
const UIComponent = ({ data, onAction }) => (
  <div className="widget">
    <h2>{data.title}</h2>
    <p>{data.content}</p>
    <button onClick={onAction}>Click me</button>
  </div>
);

// ContainerComponent.js
const ContainerComponent = () => {
  const [data, setData] = useState(null);

  useEffect(() => {
    // Fetch data here
    fetchData().then(setData);
  }, []);

  const handleAction = () => {
    // Handle action here
  };

  if (!data) return <div>Loading...</div>;

  return <UIComponent data={data} onAction={handleAction} />;
};

// Usage
const Widget = () => <ContainerComponent />;

By following these guidelines, you can create modular, reusable widgets that separate the UI concerns from data management and business logic, making your frontend more maintainable and scalable[1][2][5].
