NG Live Development Server，然后启动Chrome，在短短一个F5点击？
launch.json并tasks.json在这里做，那就太好了。据我了解，launch.json是启动节点服务器并监听端口8080，并tasks.json指示使用npm和执行命令ng serve来运行该应用程序。
看起来VS Code团队现在正在存储调试配方。
https://github.com/Microsoft/vscode-recipes/tree/master/Angular-CLI
{
"version": "0.2.0",
"configurations": [
{
"name": "Launch Chrome with ng serve",
"type": "chrome",
"request": "launch",
"url": "http://localhost:4200",
"webRoot": "${workspaceRoot}"
},
{
"name": "Launch Chrome with ng test",
"type": "chrome",
"request": "launch",
"url": "http://localhost:9876/debug.html",
"webRoot": "${workspaceRoot}"
},
{
"name": "Launch ng e2e",
"type": "node",
"request": "launch",
"program": "${workspaceRoot}/node_modules/protractor/bin/protractor",
"protocol": "inspector",
"args": ["${workspaceRoot}/protractor.conf.js"]
}
]
}
有两种不同的方法。您可以启动新流程或将其附加到现有流程。
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": "${workspaceFolder}"
}
]
}
通过执行以下命令从Angular CLI运行Webpack开发服务器 npm start
为此，您需要在打开端口的调试器模式下运行Chrome（在我的情况下为9222）：
苹果电脑：
/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=9222
视窗：
chrome.exe --remote-debugging-port=9222
launch.json 文件将以以下方式显示：
{
"version": "0.2.0",
"configurations": [
{
"name": "Chrome Attach",
"type": "chrome",
"request": "attach",
"port": 9222,
"url": "http://localhost:4200/",
"webRoot": "${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，并在其中举例说明了这种方法。
chrome.exe --remote-debugging-port=9222。一次性配置是否还有其他选择
在Visual Studio Code网站上对此进行了详细说明：https：//code.visualstudio.com/docs/nodejs/angular-tutorial
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}"
}
]
}
这是一个更轻便的解决方案，可用于Angular 2+（我正在使用Angular 4）
如果您运行MEAN堆栈，还添加了Express Server的设置。

// Use IntelliSense to learn about possible Node.js debug attributes.
// Hover to view descriptions of existing attributes.

"version": "0.2.0",
"configurations": [
{
"name": "Launch Angular Client",
"type": "chrome",
"request": "launch",
"url": "http://localhost:4200",
"runtimeArgs": [
"--user-data-dir",
"--remote-debugging-port=9222"
],
"sourceMaps": true,
"trace": true,
"webRoot": "${workspaceRoot}/client/",
"userDataDir": "${workspaceRoot}/.vscode/chrome"
},
{
"type": "node",
"request": "launch",
"name": "Launch Express Server",
"program": "${workspaceRoot}/server/bin/www",
"outFiles": [
"${workspaceRoot}/out/**/*.js"
]
}
]
}
@Asesjix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shell是，命令调用start之前已经添加，ng serve因此ng serve可以存在于自己的进程中，并且不会阻止调试器启动：
task.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": "${workspaceFolder}",
"preLaunchTask": "ng serve"
}
]
}
就我而言，我没有使用原始的Angular项目文件夹树，我知道webRoot/ {workspaceFolder}位出了点问题，但是我所有的实验都没有结果。从另一个SO答案中获得了一个提示，如果再次找到它，我将其链接。
帮助我的是{workspaceFolder}在运行时查找变量的内容，然后将其修改为您的“ src”文件夹中的“ app / *”位置。为了找到它，我preLaunchTask在launch.json文件中添加了一个，并输出了值的任务{workspaceFolder}。
launch.json，在安装Chrome调试器后显示
{
"version": "0.2.0",
"configurations": [
{
"type": "chrome",
"request": "launch",
"name": "Launch Chrome against localhost",
"url": "http://localhost:4200",
"webRoot": "${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 = ${workspaceFolder}"],
"type": "shell"
}
]
}
知道$ {workspaceFolder}的值后，便将其固定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已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。
这是您可以使用的所有变量的链接：
