Expo DevClient

允许创建开发版本并包含有用开发工具的库。

expo-dev-client 在你的调试版本中添加了各种有用的开发工具：

¥expo-dev-client adds various useful development tools to your debug builds:

• 一个可配置的启动器 UI，因此你可以启动更新（例如来自 PR 预览）并在开发服务器之间切换，而无需重新编译原生应用

  ¥A configurable launcher UI, so you can launch updates (such as from PR previews) and switch between development servers without needing to recompile the native app

• 改进的调试工具（例如对 检查网络请求 的支持）

  ¥Improved debugging tools (such as support for inspecting network requests)

• 强大且可扩展的开发者菜单 UI

  ¥A powerful and extensible developer menu UI

Expo 文档引用了包含 expo-dev-client 和 开发构建 的调试版本。

¥Expo documentation refers to debug builds that include expo-dev-client as development builds.

安装

¥Installation

如果你要在 现有的 React Native 应用 中安装它，请先在项目中安装 expo。然后，按照 在现有的 React Native 中安装 expo-dev-client 项目 中的说明进行操作。

¥If you are installing this in an existing React Native app, start by installing expo in your project. Then, follow the instructions from Install expo-dev-client in an existing React Native project.

应用配置中的配置

¥Configuration in app config

如果你在项目中使用配置插件（EAS 构建 或 npx expo run:[android|ios]），则可以使用其内置的 配置插件 配置开发客户端启动器。该插件允许你配置无法在运行时设置的各种属性，并且需要构建新的应用二进制文件才能生效。

¥You can configure development client launcher using its built-in config plugin if you use config plugins in your project (EAS Build or npx expo run:[android|ios]). The plugin allows you to configure various properties that cannot be set at runtime and require building a new app binary to take effect.

Example app.json with config plugin

{
"expo": {
  "plugins": [
    [
      "expo-dev-client",
      {
        "launchMode": "most-recent"
      }
    ]
  ]
}
}
