前段开发：配置VSCode像IDEA一样调试VUE项目

如果不配置VSCode调试，那么我们的前段项目一般都是在浏览器中的开发者工具中调试，这样对于使用习惯了IDEA开发调试的人特别不习惯，这几天个人研究了下VSCode中的代码调试功能，做以下记录：

1、使用插件调试：Microsoft Edge Tools for VS Code

（1）、在是VSCode中下载"Microsoft Edge Tools for VS Code"插件：

（2）、使用"Microsoft Edge Tools for VS Code"插件做调试：

a、点击侧边栏上的"Microsoft Edge Tools for VS Code"插件图标，会提示你在"launch.json"中生成相关的调试配置信息，生成这个文件之后，可以添加其他的调试配置信息，但是请不要删除任何东西，否则插件启动调试的时候就会提示你重新生成与它相关的配置信息。

{"configurations": [{"type": "pwa-msedge","name": "Launch Microsoft Edge","request": "launch","runtimeArgs": ["--remote-debugging-port=9222"],"url": "/home/huanzi/.vscode/extensions/ms-edgedevtools.vscode-edge-devtools-2.1.1/out/startpage/index.html", // Provide your project's url to finish configuring"presentation": {"hidden": true}},{"type": "pwa-msedge","name": "Launch Microsoft Edge in headless mode","request": "launch","runtimeArgs": ["--headless","--remote-debugging-port=9222"],"url": "/home/huanzi/.vscode/extensions/ms-edgedevtools.vscode-edge-devtools-2.1.1/out/startpage/index.html", // Provide your project's url to finish configuring"presentation": {"hidden": true}},{"type": "vscode-edge-devtools.debug","name": "Open Edge DevTools","request": "attach","url": "/home/huanzi/.vscode/extensions/ms-edgedevtools.vscode-edge-devtools-2.1.1/out/startpage/index.html", // Provide your project's url to finish configuring"presentation": {"hidden": true}}],"compounds": [{"name": "Launch Edge Headless and attach DevTools","configurations": ["Launch Microsoft Edge in headless mode","Open Edge DevTools"]},{"name": "Launch Edge and attach DevTools","configurations": ["Launch Microsoft Edge","Open Edge DevTools"]}]
}

b、配置vue项目的vue.config.js配置的文件，3.x版本以上的VUE-CLI就用以下配置：

module.exports = {configureWebpack: {devtool: "source-map",},
};

c、启动项目之后，对"launch.json"做如下修改，即可启用插件像IDEA一样调试项目。一定要在原来的基础上增加，主要是增加"url": "http://localhost:8080",``"webRoot": "${workspaceFolder}"这两个配置：
"url": "http://localhost:8080"：这个就是启动项目后，自己的项目访问路劲。
"webRoot": "${workspaceFolder}"：这个是项目源码位置，注意，新版的VsCode中${workspaceFolder}已经包含了src目录，这里直接写${workspaceFolder}就可以，如果启动调试的时候提示无法 连接连接到目标，那么试着改成${workspaceFolder}/src。

{"configurations": [{"type": "pwa-msedge","name": "Launch Microsoft Edge","request": "launch","runtimeArgs": ["--remote-debugging-port=9222"],"url": "http://localhost:8080","webRoot": "${workspaceFolder}","presentation": {"hidden": true},"smartStep": true, //自动跳过未映射的代码"skipFiles": ["<node_internals>/**/*.js", //跳过node核心模块代码"${workspaceFolder}/node_modules/**/*.js","${workspaceFolder}/src/node_modules/**/*.js","${workspaceFolder}/src/asserts/js/webpack:/app/webpack/**", //忽略webpack源码"${workspaceFolder}/src/asserts/js/webpack:/app/node_modules/**" //忽略各种包文件源码] //跳过文件},{"type": "pwa-msedge","name": "Launch Microsoft Edge in headless mode","request": "launch","runtimeArgs": ["--headless","--remote-debugging-port=9222"],"url": "http://localhost:8080","webRoot": "${workspaceFolder}","presentation": {"hidden": true},"smartStep": true, //自动跳过未映射的代码"skipFiles": ["<node_internals>/**/*.js", //跳过node核心模块代码"${workspaceFolder}/node_modules/**/*.js","${workspaceFolder}/src/node_modules/**/*.js","${workspaceFolder}/src/asserts/js/webpack:/app/webpack/**", //忽略webpack源码"${workspaceFolder}/src/asserts/js/webpack:/app/node_modules/**" //忽略各种包文件源码] //跳过文件},{"type": "vscode-edge-devtools.debug","name": "Open Edge DevTools","request": "attach","url": "http://localhost:8080","webRoot": "${workspaceFolder}","presentation": {"hidden": true},"smartStep": true, //自动跳过未映射的代码"skipFiles": ["<node_internals>/**/*.js", //跳过node核心模块代码"${workspaceFolder}/node_modules/**/*.js","${workspaceFolder}/src/node_modules/**/*.js","${workspaceFolder}/src/asserts/js/webpack:/app/webpack/**", //忽略webpack源码"${workspaceFolder}/src/asserts/js/webpack:/app/node_modules/**" //忽略各种包文件源码] //跳过文件}],"compounds": [{"name": "Launch Edge Headless and attach DevTools","configurations": ["Launch Microsoft Edge in headless mode","Open Edge DevTools"]},{"name": "Launch Edge and attach DevTools","configurations": ["Launch Microsoft Edge","Open Edge DevTools"]}]
}

d、点击"Microsoft Edge Tools for VS Code"插件Launch Project按钮，开始代码调试：

2、使用VSCode自带调试功能做调试

（1）、配置vue项目的vue.config.js配置的文件，3.x版本以上的VUE-CLI就用以下配置：

module.exports = {configureWebpack: {devtool: "source-map",},
};

（2）、启动项目后，点击侧边栏中的调试按钮，会提示你生成"launch.json"文件，对"launch.json"做如下修改，即可启用插件像IDEA一样调试项目。
注意经过个人验证：使用VSCode自带的调试功能的时候，"webRoot"需要配置成 "${workspaceFolder}/src"这样才行，否则就是报错不能连接到目标的错误而无法启动调试。

{"configurations": [{"name": "Launch Chrome","request": "launch","type": "chrome","url": "http://localhost:8080","webRoot": "${workspaceFolder}/src"}]
}

（3）、接下来开始调试项目，其他和插件使用一样，唯一的区别在于：插件将浏览器集成在VSCode中，而VSCode自带的调试功能如果不下载Chrome插件，那么就只能调起外部浏览器调试。
