Vue cli2.0 项目中使用Monaco Editor编辑器

monaco-editor 是微软出的一条开源web在线编辑器
支持多种语言，代码高亮，代码提示等功能，与Visual Studio Code 功能几乎相同。

在项目中可能会用带代码编辑功能，或者展示代码。对于习惯使用vsCode的开发者来说使用monaco-editor是非常不错的选择。

安装依赖

cnpm install monaco-editor --save

cnpm install monaco-editor-webpack-plugin --save-dev //webpack 4.x 以上版本不需要执行此命令

修改webpack.base.conf.js配置文件,如图：

const MonacoWebpackPlugin = require('monaco-editor-webpack-plugin');
...

module.exports = {
  ...
  plugins: [
    ...
    new MonacoWebpackPlugin()
  ]
};

引用editor组件

<template>
  <div>
    <el-tabs type="border-card">
      <el-tab-pane :lazy="true">
        <span slot="label"><i class="el-icon-document"></i> HTML</span>
        <MyEditor
          :language="'html'"
          :codes="htmlCodes"
          @onMounted="htmlOnMounted"
          @onCodeChange="htmlOnCodeChange" />
      </el-tab-pane>
      <el-tab-pane label="Javascript" :lazy="true">
        <MyEditor
          :language="'javascript'"
          :codes="javascriptCodes"
          @onMounted="javascriptOnMounted"
          @onCodeChange="javascriptOnCodeChange" />
      </el-tab-pane>
      <el-tab-pane label="CSS" :lazy="true">
        <MyEditor
          :language="'css'"
          :codes="cssCodes"
          @onMounted="cssOnMounted"
          @onCodeChange="cssOnCodeChange" />
      </el-tab-pane>
    </el-tabs>
  </div>
</template>

<script>
 import MyEditor from './myEditor'
export default {
  components:{
    MyEditor
  },
  data () {
    return {
      htmlCodes:'<div>This is html</div>',
      javascriptCodes:'console.log("This is javascript")',
      cssCodes:'body{}',
      htmlEditor:null,
      jsEditor:null,
      cssEditor:null,
    }
  },
  methods:{
    htmlOnMounted(edit){
      this.htmlEditor = edit;
    },
    javascriptOnMounted(edit){
      this.jsEditor = edit;
    },
    cssOnMounted(edit){
      this.cssEditor = edit;
    },
    htmlOnCodeChange(value,event){},
    javascriptOnCodeChange(value,event){},
    cssOnCodeChange(value,event){},
  }
}
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>

</style>

效果图如下：
