vue3-element-admin集成monaco-editor

安装依赖

执行命令：

pnpm install monaco-editor

配置 vite.config.ts

在 optimizeDeps 中新增monaco所需组件

// 预加载项目必需的组件
    optimizeDeps: {
      include: [
        "monaco-editor/esm/vs/language/json/json.worker",
        "monaco-editor/esm/vs/language/css/css.worker",
        "monaco-editor/esm/vs/language/html/html.worker",
        "monaco-editor/esm/vs/language/typescript/ts.worker",
        "monaco-editor/esm/vs/editor/editor.worker",
      ],
    },

自定义组件

在src/components下新增目录 MonacoEditor，在该目录下新建 index.vue , 内容如下：

<template>
  <div class="editor" ref="dom"></div>
</template>

<script lang="ts">
import { onMounted, ref, defineComponent, watch, onUnmounted, shallowRef } from "vue";
import * as monaco from "monaco-editor";
import EditorWorker from "monaco-editor/esm/vs/editor/editor.worker?worker";

//https://github.com/vitejs/vite/discussions/1791
export default defineComponent({
  name: "vsCode",
  props: {
    modelValue: {
      type: String,
      default: ""
    },
    theme: {
      type: String,
      default: "vs"
    },
    language: { type: String, default: "json" },
    options: Object
  },
  emits: ["change", "update:modelValue"],
  setup(props, { emit }) {
    const dom = ref();
    const vs = shallowRef();
    const self: any = window;

    self.MonacoEnvironment = {
      getWorker() {
        return new EditorWorker();
      }
    };

    onMounted(() => {
      const editor = monaco.editor.create(dom.value, {
        model: monaco.editor.createModel(props.modelValue, props.language),
        tabSize: 2,
        automaticLayout: true,
        scrollBeyondLastLine: false,
        theme: props.theme,
        ...props.options
      });
      vs.value = editor;
      editor.onDidChangeModelContent(() => {
        const value = editor.getValue();
        emit("update:modelValue", value);
        emit("change", value);
      });
      watch(
        () => props.modelValue,
        (vl) => {
          if (vl !== editor.getValue()) {
            editor.setValue(vl);
          }
        }
      );
      watch(
        () => props.theme,
        (vl) => {
          monaco.editor.setTheme(vl);
        }
      );
      watch(
        () => props.language,
        (vl) => {
          monaco.editor.setModelLanguage(editor.getModel() as monaco.editor.ITextModel, vl);
        }
      );
      watch(
        () => props.options,
        (vl) => {
          editor.updateOptions(vl as monaco.editor.IEditorOptions);
        }
      );
    });

    onUnmounted(() => {
      vs.value && vs.value.dispose();
    });

    return { dom };
  }
});
</script>

<style scoped>
.editor {
  height: 100%;
}
</style>

全局注册组件

在 components.d.ts 增加如下代码：

 declare module "vue" {
  export interface GlobalComponents {
    MonacoEditor: (typeof import("../components/MonacoEditor/index.vue"))["default"];
  }
}

使用组件

<template>
	<MonacoEditor class="editor" v-model="formData.content" theme="vs" language="java"
	                            style="width:100%; height: 420px; border: 1px solid #ccc" />
</template>
<script setup lang="ts">
/**
 * 引入 MonacoEditor 组件
 * */
import MonacoEditor from "@/components/MonacoEditor/index.vue";
const formData = reactive({
  content: "", // 存储编辑器内容
});
</script>
