Vue and Canvas: How to achieve gorgeous animation effects

Introduction:
In Web development, animation effects are one of the important factors that are pleasing to the eye. Vue is a popular JavaScript framework, while Canvas is an HTML element used for drawing graphics and animations. This article will introduce how to combine Vue and Canvas to achieve gorgeous animation effects, and provide code examples for readers' reference.

New Vue project
First, we need to create a Vue project. Run the following command in the command line:
```
vue create vue-canvas-animation
```
Copy after login
Then, select the default configuration to complete the project creation process. Enter the project directory and start the development server:
```
cd vue-canvas-animation
npm run serve
```
Copy after login
By accessing http://localhost:8080 in the browser, you will see the initial interface of the Vue project.
Add Canvas element
In the src directory of the Vue project, create a new component file CanvasAnimation.vue. In this file, we will use the Canvas element to achieve animation effects. In the template tag, add the following code:
```
<template>
  <div>
 <canvas ref="canvas"></canvas>
  </div>
</template>
```
Copy after login
This code will create an empty Canvas element. Through the ref attribute, we can reference the element in the Vue component.
Using Vue's life cycle hooks and Canvas API
In the Vue component, we can use the life cycle hook function to control the rendering and destruction of the page. Here, we will use the created hook function to initialize the Canvas and draw the animation in the mounted hook function.
