Vue cli2.0 項目中使用Monaco Editor編輯器

monaco-editor 是微軟出的一條開源web在線編輯器
支持多種語言，代碼高亮，代碼提示等功能，與Visual Studio Code 功能幾乎相同。

在項目中可能會用帶代碼編輯功能，或者展現代碼。對於習慣使用vsCode的開發者來講使用monaco-editor是很是不錯的選擇。

安裝依賴

cnpm install monaco-editor --save

cnpm install monaco-editor-webpack-plugin --save-dev

修改webpack.base.conf.js配置文件,如圖：

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

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