## README

This is a new [**React Native**](https://reactnative.dev) project, bootstrapped using [`@react-native-community/cli`](https://github.com/react-native-community/cli).

# Getting Started

> **Note**: Make sure you have completed the [Set Up Your Environment](https://reactnative.dev/docs/set-up-your-environment) guide before proceeding.

## Step 1: Start Metro

First, you will need to run **Metro**, the JavaScript build tool for React Native.

To start the Metro dev server, run the following command from the root of your React Native project:

```sh
# Using npm
npm start

# OR using Yarn
yarn start
```

## Step 2: Build and run your app

With Metro running, open a new terminal window/pane from the root of your React Native project, and use one of the following commands to build and run your Android or iOS app:

### Android

```sh
# Using npm
npm run android

# OR using Yarn
yarn android
```

### iOS

For iOS, remember to install CocoaPods dependencies (this only needs to be run on first clone or after updating native deps).

The first time you create a new project, run the Ruby bundler to install CocoaPods itself:

```sh
bundle install
```

Then, and every time you update your native dependencies, run:

```sh
bundle exec pod install
```

For more information, please visit [CocoaPods Getting Started guide](https://guides.cocoapods.org/using/getting-started.html).

```sh
# Using npm
npm run ios

# OR using Yarn
yarn ios
```

If everything is set up correctly, you should see your new app running in the Android Emulator, iOS Simulator, or your connected device.

This is one way to run your app — you can also build it directly from Android Studio or Xcode.

## Step 3: Modify your app

Now that you have successfully run the app, let's make changes!

Open `App.tsx` in your text editor of choice and make some changes. When you save, your app will automatically update and reflect these changes — this is powered by [Fast Refresh](https://reactnative.dev/docs/fast-refresh).

When you want to forcefully reload, for example to reset the state of your app, you can perform a full reload:

- **Android**: Press the <kbd>R</kbd> key twice or select **"Reload"** from the **Dev Menu**, accessed via <kbd>Ctrl</kbd> + <kbd>M</kbd> (Windows/Linux) or <kbd>Cmd ⌘</kbd> + <kbd>M</kbd> (macOS).
- **iOS**: Press <kbd>R</kbd> in iOS Simulator.

## Congratulations! :tada:

You've successfully run and modified your React Native App. :partying_face:

# 创建项目

- java 17
- node 18

又跟以前不一样了

> https://reactnative.dev/docs/getting-started-without-a-framework#step-1-creating-a-new-application

使用 `jenv` 设置这个项目下运行 `java` 都用 `17.0` 的

```bash
jenv local 17.0
```

新建项目了，指定版本号的话就带上 `version` 参数

```bash
npx @react-native-community/cli@latest init RNApp

npx @react-native-community/cli@X.XX.X init AwesomeProject --version X.XX.X
```

# 运行

## `Android`

> https://reactnative.dev/docs/running-on-device?platform=android

如果直接 `yarn android` 报错的话，那么先用 `as` 打开项目运行一遍，然后再运行 `yarn android`

## `iOS`

> https://reactnative.dev/docs/running-on-device?platform=ios

## ios原生库安装

这个也跟以前不一样了, 以前是用 `pod install` 安装的，现在是用 `bundle` 安装的

1. `cd ios` 导航到 `ios` 文件夹。
2. `bundle install` 安装 `Bundler`
3. `bundle exec pod install` 安装由 `CocoaPods` 管理的 `iOS` 依赖项。

只要 `Gemfile` 没改, 都不需要重复执行 `bundle install`。

### 安装 `SocketRocket` 失败

> https://github.com/facebook/react-native/issues/38300

CocoaPods could not find compatible versions for pod "SocketRocket"

- 解决方法

运行 `bundle exec pod install --repo-update`

## 然后再运行

直接 `xcode` 打开项目运行，这个要设置签名啥的，用命令行会报错

# 调试

> https://reactnative.dev/docs/debugging#opening-devtools

以前那个 `react-native-debugger` 有点问题，现在用自带的调试器

启动服务后，直接在控制台按 `j` 即可

## 调试 `redux` 的时候，需要用这个工具 `reactotron`

> https://github.com/infinitered/reactotron/blob/master/docs/quick-start/react-native.md#installing-reactotronapp

打开了 `reactotron` 后，先反转一下端口，然后刷新一下 `app` ，理论上就连上了

```bash
adb reverse tcp:9090 tcp:9090
```

# 发布到谷歌

```
npx react-native build-android --mode=release
```

生成的 AAB 可以在 android/app/build/outputs/bundle/release/app-release.aab 下找到，并且可以上传到 Google Play。

# 测试应用程序的发布版本

```
yarn android --mode release
yarn ios --mode Release
```
