Animated Box in Vue with TypeScript

This challenge focuses on implementing a simple animation in a Vue.js application using TypeScript. You'll create a component that displays a box and animates its position (both horizontally and vertically) over time, demonstrating basic Vue reactivity and animation principles. This is a fundamental skill for creating dynamic and engaging user interfaces.

Problem Description

You are tasked with creating a Vue component called AnimatedBox.vue that displays a square box. The box should initially be positioned at the top-left corner of its container. Upon mounting, the box should smoothly animate its position to the bottom-right corner of the container over a period of 5 seconds. The animation should be continuous, looping back to the top-left corner after reaching the bottom-right corner and repeating. The box should have a background color of lightblue and a width and height of 100px.

Key Requirements:

• Component Structure: Create a functional component named AnimatedBox.
• Reactivity: Use Vue's reactivity system to manage the box's position (x and y coordinates).
• Animation: Implement the animation using setInterval or setTimeout to update the position values at regular intervals. Consider using requestAnimationFrame for smoother animations.
• Looping: The animation should loop continuously.
• Styling: The box should be styled with a lightblue background, a width of 100px, and a height of 100px.
• TypeScript: The component must be written in TypeScript.

Expected Behavior:

1. When the component mounts, the box should start at coordinates (0, 0).
2. The box should smoothly move to coordinates (containerWidth - 100, containerHeight - 100) over 5 seconds.
3. After reaching the bottom-right corner, the box should smoothly return to the top-left corner over another 5 seconds.
4. This movement should repeat indefinitely.
5. The box should always be visible and within the bounds of its container.

Edge Cases to Consider:

• Container Size: The component should adapt to different container sizes. Assume the container's width and height are available as props.
• Animation Speed: The animation speed should be consistent regardless of browser performance.
• Component Unmounting: The animation should stop when the component is unmounted to prevent memory leaks.

Examples

Example 1:

Input: containerWidth = 500, containerHeight = 300
Output: A lightblue square (100x100) animating from (0,0) to (400,200) and back, continuously.
Explanation: The box moves across the container, respecting the container's dimensions.

Example 2:

Input: containerWidth = 200, containerHeight = 150
Output: A lightblue square (100x100) animating from (0,0) to (100,50) and back, continuously.
Explanation: The box moves within a smaller container.

Constraints

• Animation Duration: The animation from top-left to bottom-right should take 5 seconds.
• Container Dimensions: The container width and height will be provided as props to the component.
• Box Size: The box should always be 100px x 100px.
• Performance: The animation should be reasonably smooth and not cause noticeable performance issues on typical devices. Avoid excessively complex calculations within the animation loop.
• TypeScript: Strict type checking is expected.

Notes

• Consider using requestAnimationFrame for smoother animations compared to setInterval or setTimeout.
• You'll need to manage the state of the animation (e.g., current position, animation direction) within the component.
• Remember to clean up the animation interval/timeout when the component is unmounted to prevent memory leaks.
• The container's width and height are assumed to be available as props. You don't need to handle getting these values from the DOM directly.
• Focus on the core animation logic; you don't need to implement complex UI elements or interactions beyond the box's movement.
