3.组件封装与使用

1. monacoEditor.vue组件

   <template>
     <div ref="codeEditBox" class="codeEditBox"></div>
   </template>
   
   <script lang="ts">
   import { defineComponent, onBeforeUnmount, onMounted, ref, watch } from 'vue'

   import tsWorker from 'monaco-editor/esm/vs/language/typescript/ts.worker?worker'
   import EditorWorker from 'monaco-editor/esm/vs/editor/editor.worker?worker'
   import * as monaco from 'monaco-editor'
   
   export default defineComponent({
     name: 'monacoEditor',
     props: editorProps,

             if (newValue !== value) {
               editor.setValue(newValue)
             }
           }
         }
       )
   
       watch(

2. monacoEditorType.ts类型定义文件

   import { PropType } from 'vue'
   
   export type Theme = 'vs' | 'hc-black' | 'vs-dark'
   export type FoldingStrategy = 'auto' | 'indentation'
   export type RenderLineHighlight = 'all' | 'line' | 'none' | 'gutter'
   export interface Options {
     automaticLayout: boolean // 自适应布局
     foldingStrategy: FoldingStrategy // 折叠方式  auto | indentation
     renderLineHighlight: RenderLineHighlight // 行亮
     selectOnLineNumbers: boolean // 显示行号
     minimap: {
       // 关闭小地图
       enabled: boolean
     }
     readOnly: boolean // 只读
     fontSize: number // 字体大小
     scrollBeyondLastLine: boolean // 取消代码后面一大段空白
     overviewRulerBorder: boolean // 不要滚动条的边框
   }
   
   export const editorProps = {
     modelValue: {
       type: String as PropType<string>,
       default: null,
     },
     width: {
       type: [String, Number] as PropType<string | number>,
       default: '100%',
     },
     height: {
       type: [String, Number] as PropType<string | number>,
       default: '100%',
     },
     language: {
       type: String as PropType<string>,
       default: 'javascript',
     },
     theme: {
       type: String as PropType<Theme>,
       validator(value: string): boolean {
         return ['vs', 'hc-black', 'vs-dark'].includes(value)
       },
       default: 'vs-dark',
     },
     options: {
       type: Object as PropType<Options>,
       default: function () {
         return {
           automaticLayout: true,
           foldingStrategy: 'indentation',
           renderLineHighlight: 'all',
           selectOnLineNumbers: true,
           minimap: {
             enabled: true,
           },
           readOnly: false,
           fontSize: 16,
           scrollBeyondLastLine: false,
           overviewRulerBorder: false,
         }
       },

3. 在父组件中使用

   <script lang="ts" setup>
   import * as monaco from 'monaco-editor'
   const value = ref('let a = 234')
   const language = ref('javascript')
   const editorMounted = (editor: monaco.editor.IStandaloneCodeEditor) => {
     console.log('editor实例加载完成', editor)
   }
   </script>
   
   <template>
     <div class="container">
       <monacoEditor
         v-model="value"
         :language="language"
         width="800px"
         height="500px"
         @editor-mounted="editorMounted"
       ></monacoEditor>
     </div>
   </template>
