vue2项目集成canvas-editor文本编辑器

vue2项目集成 canvas-editor 富文本编辑器; canvas-ediotr并不是一款开箱即用的插件, 需要通过下载源码来进行手动集成到项目中;
源码地址: https://github.com/Hufe921/canvas-editor
官方文档: https://hufe.club/canvas-editor-docs/guide/schema.html
本地运行结果:

Canvas-Editor环境配置

canvas-editor通过 vue3 + TypeScript 进行编写的, 考虑到大部分的 vue2项目中并没有集成TypeScript的环境, 要先进行环境的配置,需要配置的环境如下: npm install, 可能会出现报错,若是报错,建议 使用 npm clean 之后, 继续执行 npm install;
package.json

"dependencies": {
    "core-js": "^3.8.3",
    "vue": "^2.6.14",
	
    "@hufe921/canvas-editor": "^0.9.86",
    "@types/prismjs": "^1.26.0",
    "@typescript-eslint/eslint-plugin": "5.62.0",
    "@typescript-eslint/parser": "5.62.0",
    "css-loader": "^6.5.0",
    "style-loader": "^2.0.0",
    "ts-loader": "^9.5.1",
    "vue-loader": "^15.9.7",
    "webpack": "^5.74.0"
  }复制

创建 tsconfig.json 服务于 TypeScript
tsconfig.json

{
  "compilerOptions": {
    "target": "es5",
    "module": "esnext",
    "lib": ["es2015","dom"],
    "strict": true,
    "jsx": "preserve",
    "importHelpers": true,
    "moduleResolution": "node",
    "experimentalDecorators": true,
    "allowSyntheticDefaultImports": true,
    "esModuleInterop": true,
    "sourceMap": true,
    "baseUrl": "..",
    "paths": {
      "@/*": ["src/*"]
    }
  },
  "include": [
    "src/**/*.ts",
    "src/**/*.tsx",
    "src/**/*.vue",
    "tests/**/*.ts",
    "tests/**/*.tsx",
    "tests/**/*.vue"],
  "exclude": ["node_modules","dist"]
}复制

修改 vue.config.js文件

const { defineConfig } = require('@vue/cli-service')
module.exports = defineConfig({
  transpileDependencies: true,
  // 添加上 configureWebpack 配置
  configureWebpack: {
    module: {
      rules: [
        {
          test: /\.ts$/,
          loader: 'ts-loader',
          options: { appendTsSuffixTo: [/\.vue$/] },
          exclude: /node_modules/
        }
      ]
    },
    resolve: {
      extensions: ['.ts', '.js', '.vue', '.json'],
      alias: {
        '@': require('path').resolve(__dirname, 'src')
      }
    }
  }
})复制

将 canvas-editor 源码中的部分文件, 复制过来

其中的 canvas.js 和 index.vue 文件是根据源代码中的 main.ts 和 index.html进行了变化, 用于服务当前的项目; components文件夹中只需获取 dialog.css文件 和 signature.css文件即可;
index.vue
