+   * ![](./chrome-devtool.PNG)
+
+2. Debug within VSCode
+
+   * [Reference](https://vuejs.org/v2/cookbook/debugging-in-vscode.html)

+
+     
+
+   * For `vue-cli` 3.x and above, add this to `vue.config.js` at root folder
+
+     ```javascript
+     module.exports = {
+     
+       configureWebpack: {
+         devtool: 'source-map',
+       },
+     };
+     ```
+
+     
+
+   * For `vue-cli` 2.x, add this to `config/index.js` (No verified) 
+
+     ```javascript
+     devtool: 'source-map',
+     ```
+
+     
+
+   * Update the vscode `launch.json`
+
+     ```json
+         "configurations": [

+                 "url": "http://localhost:5001",
+                 "webRoot": "${workspaceFolder}/src",
+                 "breakOnLoad": true,
+                 "sourceMapPathOverrides": {
+                   "webpack:///src/*": "${webRoot}/*"
+                 }
+             }
