debugging - 使用 Create-React-App 调试 VSCode

Question

我想设置我的 VS Code 来调试我使用“create-react-app”创建的 React-app。

我试过这个配置:

{
    "version": "0.1.0",
    "configurations": [
        {
            "name": "Launch node",
            "type": "node",
            "request": "launch",
            "program": "${workspaceRoot}/src/index.js",
            "cwd": "${workspaceRoot}",
            "preLaunchTask": null,
            "runtimeExecutable": null,
            "runtimeArgs": [
                "--nolazy"
            ],
            "env": {
                "NODE_ENV": "development"
            },
            "sourceMaps": true,
            "outFiles": []
        },
        {
            "name": "Attach",
            "type": "node",
            "request": "attach",
            "port": 9222,
            "address": "localhost",
            "restart": false,
            "sourceMaps": false,
            "localRoot": "${workspaceRoot}",
            "remoteRoot": null
        }
    ]
}

但我收到以下错误:

Debugger listening on port 11198
e:\form\src\index.js:1
(function (exports, require, module, __filename, __dirname) { import React from 'react';
                                                             ^^^^^^

SyntaxError: Unexpected reserved word

...

我想我需要将 'preLaunchTask' 设置为 babel 或将 'outFiles' 设置为某个 dist 文件夹，但我不知道我应该将它指向哪里。

我会很感激的想法。

你的配置不正确。它应该是:

{
  "version": "0.2.0",
  "configurations": [{
    "name": "Chrome",
    "type": "chrome",
    "request": "launch",
    "url": "http://localhost:3000",
    "webRoot": "${workspaceRoot}/src",
    "userDataDir": "${workspaceRoot}/.vscode/chrome",
    "sourceMapPathOverrides": {
      "webpack:///src/*": "${webRoot}/*"
    }
  }]
}
