執行並除錯你的 Ionic 專案

>在 Chrome 中執行和除錯

要在 terminal 或 cmd 或 CLI 中執行 ionic 專案，請使用以下命令 ****

 $ ionic serve

對於除錯離子專案，首先應該新增擴充套件 （用於 chrome 的偵錯程式） ，然後像這樣配置 launch.json 檔案。

 {
        "version": "0.2.0",
        "configurations": [
           
            {
          "name": "Launch in Chrome",
          "type": "chrome",
          "request": "launch",
          "url": "http://localhost:8100",
          "sourceMaps": true,
          "webRoot": "${workspaceRoot}/src"
        }
]
}

> 在 Android 中執行和除錯

對於 Android 中的 Run ionic 專案，你應該在終端或 cmd 或 CLI 中通過以下命令新增 android 平臺：

$ ionic cordova platform add android 

通過此命令構建 Android

$ ionic cordova build android

執行 android 平臺的命令

$ ionic cordova run android

現在，你的應用程式在真正的 Android 裝置上執行。

要在 Android 裝置中**除錯，**你需要在 VSCode 中新增 Cordova 或 Android Extension 。並像這樣配置 launch.json 檔案。
