Vue Native Renderer: A Minimal Canvas-Based Component

This challenge asks you to build a simplified, native renderer for a Vue component using the HTML5 Canvas API. The goal is to demonstrate understanding of Vue's component lifecycle, reactivity, and the ability to directly manipulate the DOM (in this case, a canvas) for rendering. This is useful for creating highly performant visualizations or custom UI elements that don't rely on standard DOM elements.

Problem Description

You are tasked with creating a Vue component called CanvasComponent that renders a simple animated circle on an HTML5 canvas. The circle's position should be reactive, meaning that when the component's data changes, the canvas is automatically updated. The component should handle its lifecycle events (mounted, updated) to initialize and redraw the circle.

Key Requirements:

Canvas Element: The component must render an HTML5 <canvas> element.
Reactive Data: The component should have a reactive data property x (representing the circle's x-coordinate) and y (representing the circle's y-coordinate). Initially, x and y should be set to 50.
Animation: The x coordinate should increment by 1 every 50 milliseconds, creating a simple animation.
Lifecycle Hooks: The component must use the mounted lifecycle hook to initialize the canvas context and draw the initial circle. The updated lifecycle hook should be used to redraw the circle whenever the reactive data changes.
Clear Canvas: Before redrawing, the canvas must be cleared to prevent drawing multiple circles on top of each other.
Circle Properties: The circle should have a radius of 20 and be filled with red.

Expected Behavior:

When the component is mounted, a red circle with a radius of 20 should be drawn at coordinates (50, 50) on the canvas.
The x coordinate should increment by 1 every 50 milliseconds, causing the circle to move horizontally across the canvas.
The canvas should be cleared and redrawn whenever the x or y data properties change.
The component should handle potential errors gracefully (e.g., if the canvas element is not available).

Edge Cases to Consider:

What happens if the canvas element is not present in the DOM?
How to handle potential errors during canvas drawing operations?
How to ensure efficient redrawing to avoid performance bottlenecks?

Examples

Example 1:

Input: Initial data: x = 50, y = 50
Output: A red circle with radius 20 drawn at (50, 50) on the canvas.  The circle then begins to move horizontally across the canvas.
Explanation: The component initializes the canvas context and draws the circle. The animation loop updates the x coordinate and redraws the circle.

Example 2:

Input: Data updated: x = 100, y = 75
Output: The canvas is cleared, and a red circle with radius 20 is drawn at (100, 75).
Explanation: The `updated` lifecycle hook is triggered, the canvas is cleared, and the circle is redrawn with the new coordinates.

Example 3: (Edge Case)

Input: Canvas element is not present in the DOM.
Output: The component logs an error message to the console and does not attempt to draw anything.
Explanation: The component checks for the existence of the canvas element before attempting to access its context.

Constraints

Canvas Size: The canvas should be 200x100 pixels.
Animation Interval: The animation interval should be 50 milliseconds.
TypeScript: The solution must be written in TypeScript.
Vue 3: The solution must be compatible with Vue 3.
No External Libraries: Do not use any external libraries for canvas manipulation or animation. Use only native JavaScript/TypeScript and Vue features.

Notes

Consider using requestAnimationFrame for smoother animation. While not strictly required, it's a good practice.
The focus is on demonstrating the integration of Vue's reactivity with direct canvas manipulation. A complex animation is not required.
Error handling is important. Gracefully handle cases where the canvas element is not available.
Think about how to efficiently redraw the canvas only when necessary.
