如何在visual studio代码中调试typescript文件-Java 学习之路

使用Visual Studio代码的0.3版本，我不知道如何启用源映射和调试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 . 在我的中，Sourcemap设置为true

tsconfig.json

{
    "compilerOptions": {
        "target": "ES5",
        "module": "commonjs",
        "sourceMap": true
    }
}

launch.json

{
    "version": "0.1.0",
    // List of configurations. Add new configurations or edit existing ones.  
    // ONLY "node" and "mono" are supported, change "type" to switch.
    "configurations": [
        {
            // Name of configuration; appears in the launch configuration drop down menu.
            "name": "Launch server.ts",
            // Type of configuration. Possible values: "node", "mono".
            "type": "node",
            // Workspace relative or absolute path to the program.
            "program": "server.ts",
            // Automatically stop program after launch.
            "stopOnEntry": true,
            // Command line arguments passed to the program.
            "args": [],
            // Workspace relative or absolute path to the working directory of the program being debugged. Default is the current workspace.
            "cwd": ".",
            // Workspace relative or absolute path to the runtime executable to be used. Default is the runtime executable on the PATH.
            "runtimeExecutable": null,
            // Environment variables passed to the program.
            "env": { }
        }, 
        {
            "name": "Attach",
            "type": "node",
            // TCP/IP address. Default is "localhost".
            "address": "localhost",
            // Port to attach to.
            "port": 5858
        }
    ]
}

这个配置对我来说很好：

项目分布

|-- .vscode
    |----- launch.json
|-- bin
    |----- app.js
    |----- app.js.map
|-- src
    |----- app.ts
|-- node_modules
    |-- [..]
|-- tsconfig.json
|-- [...]

这个想法是编译 src 文件夹下的打字稿并将其放在 bin 文件夹下 .

tsconfig.json

激活 sourceMap 选项很重要 .

{
    "compilerOptions": {
        "emitDecoratorMetadata": true,
        "module": "commonjs",
        "target": "ES5",
        "outDir": "bin",
        "rootDir": "src",
        "sourceMap": true
    }
}

launch.json

====编辑====

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
        }
    ]
}

请注意，如果您使用任何任务运行器作为gulp，则键 preLaunchTask 非常有用，因为IDE可以按名称检测其任务 .

这是我在2017年11月使用最新的TS和VsCode为我工作的原因

以下配置将帮助您启动服务器并在VS Code中调试TS

这就是我的 tsconfig.json 看起来像：

{
    "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 directory structure 看起来像：

enter image description here

如果你注意你会看到我的src文件夹和构建文件夹（包含结果转换的JS和 Map 文件）并存，这真的有助于我维护一个逻辑目录结构 .

好的，现在来了 launch config ：

{
            "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 .

这就是我在任务中所做的事情 nb-tsc-watch

{
            "label": "nb-tsc-watch",
            "type": "typescript",
            "tsconfig": "backend/src/tsconfig.json",
            "option": "watch",
            "problemMatcher": [
                "$tsc-watch"
            ]
        }

下面的设置用断点测试摩卡柴 . 它的工作原理是将src转换为lib目录，然后在lib中运行测试，并将sourceMapping运行回src .

    "args": ["lib/**/*.js"],
    "cwd": "${workspaceRoot}",
    "sourceMaps": true,
    "outFiles": ["${workspaceRoot}/lib/**/*.js"]

对于2017年2月更晚版本的VSCode，这对我有用（它是@manu和@tommy Falgout提供的组合）：

它假设您的json输出文件分别位于 dest 文件夹中，而您的源文件位于 src 文件夹中

/.vscode/launch.json

{
    "version": "0.2.0",
    "configurations": [{
            "type": "node",
            "request": "launch",
            "name": "Launch",
            "sourceMaps": true,
            "stopOnEntry": true,
            "console": "internalConsole",
            "cwd": "${workspaceRoot}",
            "program": "${workspaceRoot}/src/main.ts",
            "outFiles": ["${workspaceRoot}/dest/*.js"]
        },
        {
            "type": "node",
            "request": "attach",
            "name": "Attach to Process",
            "port": 5858,
            "outFiles": []
        }
    ]
}

tsconfig.json

{
    "compilerOptions": {
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "sourceMap": true,
        "module": "commonjs",
        "outDir": "dest",
        "rootDir": "src"
    },

        "node_modules"
    ]

我认为它比发布更简单，更简单......

我已经安装了 ts-node ，所以我的配置文件最终非常简单......

launch.json
```
{
        "name": "Launch index.ts",
        "type": "node",
        "request": "launch",
        "runtimeArgs": [
            "-r",
            "ts-node/register"
        ],
        "args": [
            "${workspaceFolder}/src/index.ts"
        ]
}
```
有两个值得注意的事情：
- runtimeArgs - 传递给节点以注册ts节点以处理TypeScript文件 .
- 没有 program 属性 . 要启动的TS文件的名称将作为第一个参数给出 .
这样你就不需要将TS编译成JS，你甚至可以将用TS编写的模块编译成JS .

@manu的回答指出了我正确的方向;但是，使用最新版本的VSCode，我仍然遇到了同样的问题 . 这是对我有用的修复：

我刚刚编写了自己的PowerShell函数作为preLaunchTask . 这可能是比以前更糟的解决方案，但可以在preLaunchTask字段下添加更多灵活性来注入更多任务 . 因为目前它不支持数组，并且只允许在启动操作之前运行一个任务 .

launch.json

    "version": "0.2.0",

        {
            "type": "node",

            "program": "${file}",
            "preLaunchTask": "RebuildTypeScript",
            "outFiles": [
                "${workspaceRoot}/js/**/*.js"
            ]
        }
    ]
}
