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。
