Projeto do curso Advanced React (Meta)

You've learned about render props and how it's a viable alternative to Higher Order Components to encapsulate cross-cutting concerns. In a previous video, you saw a possible implementation of a mouse position tracker using Higher Order Components. In this exercise, you'll implement the same specifications but using a render prop component instead.

Steps

Step 1

Open the App.js file.

Complete the implementation of the MousePosition component. Specifically, you'll need to:

• Implement the body of handleMousePositionChange inside useEffect. Use e.clientX and e.clientY to get the mouse position from the event object.
• Implement the return statement of the component.

Step 2

Tweak the implementation of PanelMouseLogger. The requirements are:

• The component should not receive any props.
• The component should not have any if statements.
• The component should leverage the MousePosition render prop to show the coordinates in a panel fashion. The panel UI is already provided to you, your goal is to connect the UI with the mouse position data.

Step 3

Tweak the implementation of PointMouseLogger. The requirements are:

• The component should not receive any props.
• The component should not have any if statements.
• The component should leverage the MousePosition render prop to show the coordinates in a point representation. The point UI is already provided to you, your goal is to connect the UI with the mouse position data

Save all the changes and run the app. Preview the updates in the browser, and confirm that the page shows 2 distinct interfaces that display the safe information (mouse position) in different fashion, one as a panel and another as a point coordinates.
