nuxtjs + koa2 用vscode调试node端代码

修改 launch.json

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "node",
      "request": "launch",
      "name": "Launch Program",
      "cwd": "${workspaceRoot}",
      "sourceMaps": true,
      "preLaunchTask": "npm: build",
      "program": "${workspaceFolder}/build/main.js",
      "args": ["increment", "3"],
      "stopOnEntry": false,
      "localRoot": "${workspaceRoot}",
      "outFiles": ["${workspaceRoot}/build/**"]
    },
    {
      "type": "node",
      "request": "attach",
      "name": "Attach",
      "port": 9229
    }
  ]
}

设断点 F5 执行

整个过程

• 开启 sourceMaps 支持跟踪es6
• 先build编译 es6 代码到 es5
• 启动调试
