使用Visual Studio代码的0.3版,我不知道如何启用源图并调试ts文件
我收到以下错误can't launch program '/Projects/app-server/server.ts'; enabling source maps might help
如何启用源映射和打字稿调试。我的

"name": "Launch server.ts",
// Type of configuration. Possible values: "node", "mono".

此配置对我来说很好:
|-- .vscode
|----- launch.json
|-- bin
|----- app.js
|----- app.js.map
|-- src
|----- app.ts
|-- node_modules
|-- [..]
|-- tsconfig.json
|-- [...]
想法是编译src
文件夹下的打字稿并将其放在bin
文件夹下。
激活sourceMap
选项很重要。
{
"compilerOptions": {
"emitDecoratorMetadata": true,
"module": "commonjs",
"target": "ES5",
"outDir": "bin",
"rootDir": "src",
"sourceMap": true
}

这是我目前在Visual Studio Code v1中使用的配置:
{
"version": "0.2.0",
"configurations": [
{
"args": [],
"cwd": "${workspaceRoot}",
"env": {
"NODE_ENV": "development"
},
"externalConsole": false,
"name": "DEBUG",
"outDir": "${workspaceRoot}/bin",
"preLaunchTask": "compile",
"program": "${workspaceRoot}/src/app.ts",
"request": "launch",
"runtimeArgs": [
"--nolazy"
],
"runtimeExecutable": null,
"sourceMaps": true,
"stopOnEntry": false,
"type": "node"
},
{
"name": "Attach",
"type": "node",
"request": "attach",
"port": 5858
}
]
}
注意,如果您将任务运行器用作gulp,则键{{1}}非常有用,因为IDE可以按名称检测其任务。
preLaunchTask
(输入终端ts
或执行编译任务)rm -r bin/ ; tsc

我认为它在发行版中变得越来越简单...
我已经安装了ts-node
,所以我的配置文件最终变得非常简单...
{
"name": "Launch index.ts",
"type": "node",
"request": "launch",
"runtimeArgs": [
"-r",
"ts-node/register"
],
"args": [
"${workspaceFolder}/src/index.ts"
]
}
有两点值得注意:
runtimeArgs
-传递给节点以注册ts节点以处理TypeScript文件。program
属性。将要启动的TS文件的名称改为第一个参数。这样一来,您无需将TS编译为JS,甚至可以使用TS编写的模块尚未编译为JS。

截至2017年11月,这是最新的TS和VsCode一直在为我工作
以下配置将帮助您启动服务器并在VS代码中调试TS
这就是我的 tsconfig.json :
{
"compilerOptions": {
"declaration": false,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"lib": ["es2017", "dom"],
"module": "commonjs",
"moduleResolution": "node",
"outDir": "../build",
"sourceMap": true,
"target": "es2016",
"typeRoots": [
"../node_modules/@types"
]
},
"include": [
"**/*.ts"
],
"exclude": [
"../node_modules",
"../*.js"
]
}
这就是我的目录结构:
如果你注意你会看到我的src文件夹和构建文件夹(包含结果已转换的JS和地图文件)并存,这真的有助于我维护一个逻辑目录结构。
好的,现在是启动配置:
{
"type": "node",
"request": "launch",
"name": "Start and Debug",
"preLaunchTask": "nb-tsc-watch",
"timeout": 10000,
"program": "${workspaceFolder}/backend/src/app.ts",
"restart": true,
"cwd": "${workspaceRoot}",
"outFiles": [
"${workspaceFolder}/backend//build/**/*.js"
],
"sourceMaps": true
}
您可以使用您想要使用的任何preLaunchTask,甚至可以跳过它。 如果你跳过它,你必须手动将TS转换为JS。
这就是我在我的任务中所做的nb-tsc-watch
{
"label": "nb-tsc-watch",
"type": "typescript",
"tsconfig": "backend/src/tsconfig.json",
"option": "watch",
"problemMatcher": [
"$tsc-watch"
]
}

简单,自动的配置足以满足许多使用情况-无需手动配置launch.json
。先决条件:在工作区tsconfig.json
中启用sourcemaps:
{
"compilerOptions": {
"sourceMap": true,
// ...
}
}
launch.json
只需打开或重新聚焦文件,然后按 F5 (开始调试)。如果存在多个调试环境(例如Chrome和Node.js),请选择后者。
注意:目前,launch.json
中不需要其他条目。下一个VS Code版本将随附single file debug improvements。
launch.json
转到调试视图( Ctrl Shift D ),然后单击“创建launch.json文件”。如果不存在main
,这将为package.json
的{{1}}字段文件或活动文件创建调试条目。示例:
main
注意:这要求 "configurations": [ // auto-generated
{
"type": "node",
"request": "launch",
"name": "Launch Program",
"skipFiles": [
"<node_internals>/**"
],
"program": "${workspaceFolder}\\dist\\A.js",
"preLaunchTask": "tsc: build - tsconfig.json",
"outFiles": [
"${workspaceFolder}/dist/**/*.js"
]
}
]
之前不能出现。
在launch.json
中或通过用户界面→“调试:切换自动附加”打开Auto Attach feature。
settings.json
以调试模式启动节点程序。不久之后,VS Code将开始调试。
"debug.node.autoAttach": "on" // in settings.json
或使用"Debug: Attach to Node Process"(也与node --inspect-brk dist/A.js
:launch.json
一起使用)。

如果您是从命令行运行脚本的,则在最新的Visual Studio Code版本中,可以跳过创建launch.json
的工作,这有时是一项艰巨的任务。相反,您可以将调试器自动附加到从命令行运行的任何ts-node
或node
命令中。
tsconfig.json
启用源映射-TypeScript配置需要源映射支持,否则无法进行调试。{
"compilerOptions": {
"sourceMap": true
},
}
ts-node myscript.ts
启动为
node -r ts-node/register --inspect-brk myscript.ts
您将在Node启动时看到它:
Debugger listening on ws://127.0.0.1:9229/8bb6dcc8-a73c-405e-b1fe-69a3d7789a20

如果您不想对文件名进行硬编码,而是在这里像简单的Grogi's版本一样?使用VS variable reference page中的信息,您可以做两件事:
npm i ts-node
然后 launch.json 一样(以防万一,但是您只能从中获取这一配置):
{
"version": "0.2.0",
"configurations": [
{
"name": "Launch TS",
"type": "node",
"request": "launch",
"runtimeArgs": [
"-r",
"ts-node/register"
],
"args": [
"${workspaceFolder}/${fileBasename}"
]
}
]
}
该VSC页面上的几个示例-有时您可以使用Ctrl + Space来获取它们,但对我来说不起作用:
${workspaceFolder} - /home/your-username/your-project
${workspaceFolderBasename} - your-project
${file} - /home/your-username/your-project/folder/file.ext
${relativeFile} - folder/file.ext
${relativeFileDirname} - folder
${fileBasename} - file.ext
${fileBasenameNoExtension} - file
${fileDirname} - /home/your-username/your-project/folder
${fileExtname} - .ext
${lineNumber} - line number of the cursor
${selectedText} - text selected in your code editor
${execPath} - location of Code.exe
