看起来VS Code团队现在正在存储调试配方。

有两种不同的方法。您可以启动一个新进程或附加到现有进程。
这两个过程的关键点是同时运行 webpack开发服务器和VSCode调试器。
在您的launch.json文件中，添加以下配置：
{
"version": "0.2.0",
"configurations": [
{
"name": "Angular debugging session",
"type": "chrome",
"request": "launch",
"url": "http://localhost:4200",
"webRoot": "${workspaceFolder}"
}
]
}
通过执行npm start
为此，您需要在调试器模式下以打开的端口运行Chrome（在我的情况下为9222）：
Mac：
/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=9222
Windows：
chrome.exe --remote-debugging-port=9222
launch.json文件的外观如下：
{
"version": "0.2.0",
"configurations": [
{
"name": "Chrome Attach",
"type": "chrome",
"request": "attach",
"port": 9222,
"url": "http://localhost:4200/",
"webRoot": "${workspaceFolder}"
}
]
}
npm start 在这种情况下，调试器将附加到现有的Chrome进程中，而不是启动新窗口。
我写了自己的文章，其中用插图描述了这种方法。

@Asesjix的答案非常彻底，但是正如某些人指出的那样，仍然需要多次交互才能启动ng serve，然后在Chrome中启动Angular应用程序。我使用以下配置单击一下就可以使用此功能。与@Asesjix答案的主要区别是任务类型现在为shell，并且命令调用在start之前添加了ng serve，因此ng serve可以存在于自己的进程中而不阻塞启动调试器：
tasks.json：
{
"version": "2.0.0",
"tasks": [
{
"label": "ng serve",
"type": "shell",
"command": "\"start ng serve\""
},
{
"label": "ng test",
"type": "shell",
"command": "\"start ng test\"",
}
]
}
launch.json：
{
"version": "0.2.0",
"configurations": [
{
"name": "Launch in Chrome",
"type": "chrome",
"request": "launch",
"url": "http://localhost:4200",
"webRoot": "${workspaceFolder}",
"preLaunchTask": "ng serve"
}
]
}

这是一个更轻松的解决方案，适用于Angular 2+（我正在使用Angular 4）
如果运行MEAN堆栈，还添加了Express Server的设置。

"version": "0.2.0",
"configurations": [
{
"name": "Launch Angular Client",
"type": "chrome",
"request": "launch",
"url": "http://localhost:4200",
"runtimeArgs": [
"--user-data-dir",

可以使用此配置：
{
"version": "0.2.0",
"configurations": [
{
"name": "ng serve",
"type": "chrome",
"request": "launch",
"preLaunchTask": "npm: start",
"url": "http://localhost:8080",
"webRoot": "${workspaceFolder}"
}
]
}

就我而言，我没有使用原始的Angular项目文件夹树，并且我知道webRoot / {workspaceFolder}位出了点问题，但是我所有的实验都没有结果。从另一个SO解答中得到了一个提示，如果再次找到它，我会链接它。
帮助我的是，在运行时找到变量{workspaceFolder}的内容，然后将其修改为您的“ src”文件夹中包含“ app / *”的位置。为了找到它，我在我的launch.json文件中添加了一个preLaunchTask，并执行了一个输出{workspaceFolder}值的任务。
launch.json （在安装Chrome调试器后出现）
{
"version": "0.2.0",
"configurations": [
{
"type": "chrome",
"request": "launch",
"name": "Launch Chrome against localhost",
"url": "http://localhost:4200",
"webRoot": "${workspaceFolder}/src/newProjectRoot/",
"preLaunchTask": "Echo values" //Just to see what the cryptic vs code variables actually are https://code.visualstudio.com/docs/editor/variables-reference
}
]
}
Tasks.json 默认情况下不存在。按Ctrl + Shift + p，我认为它称为“为其他命令创建任务”或类似的名称。创建task.json后似乎看不到它。您也可以在与 launch.json
相同的位置创建文件{
"version": "2.0.0",
"tasks": [
{
"label": "Echo values",
"command": "echo",
"args": ["${env:USERNAME}", "workspaceFolder = ${workspaceFolder}"],
"type": "shell"
}
]
}
一旦我知道$ {workspaceFolder}的价值，我便将其修复为指向新项目树中的src文件夹，并且一切正常。调试要求ng serve作为启动前任务或作为构建的一部分（上述示例）或在命令提示符下运行。
Here是指向您可以使用的所有变量的链接：
