0. Prepare Today's environment
Windows 10
Node v12.18.2
Android Studio 3.5
→Android StudioはAndroid SDKとAndroid Virtual Deviceを使用するため。
1. Install react-native-community/cli
「react-native-community/cli」はReact Native × Typescriptのテンプレートを提供してくれて便利。
$ npm install -g @react-native-community/cli

Thank you for using core-js ( https://github.com/zloirock/core-js ) for polyfilling JavaScript standard library!
The project needs your help! Please consider supporting of core-js on Open Collective or Patreon:

2. Check compatible versions between react-native-community/cli & react-native-community/react-native-template-typescript
react-native-community/cliのGitHubページでReact Nativeとの互換関係を確認。
インストールされたreact-native-community/cliは4.10.1なのでreact-nativeは0.62.xが対応。
react-native-community/react-native-template-typescriptのGitHubページでReact Nativeとの互換関係を確認。
インストールされるreact-nativeは0.62.xなのでreact-native-template-typescriptは6.4.xが対応。
3. Create react-native-template-typescript project
React Native × Typescriptのテンプレートでプロジェクトを作成。
ちなみに、プロジェクト名には - (ハイフン)とか使えない文字があるので注意。
npx react-native init onlibrary_frontend --template react-native-template-typescript@6.4.4
4. Check Android SDK folder
Android Studioのインストール時に格納されたAndroid SDKのフォルダを確認。
5. Create local.properties
プロジェクト直下のandroidフォルダ配下にlocal.propertiesを作成。
Android SDKの格納先を記載。
ちなみに、local.propertiesの代わりにWindows環境変数でANDROID_SDK_ROOTを作成でもOK。
$ cat android/local.properties
sdk.dir = C:\\Users\\takas\\AppData\\Local\\Android\\Sdk
6. Launch Android Virtual Device
Android Studioのインストール時に同梱されたAndroid Virtual Deviceを作成して起動。
作成する仮想モバイルデバイスは任意。
念のため、起動前にデータを削除。
7. Check Android Virtual Device ID
起動された仮想モバイルデバイスのIDを確認。
$ adb devices
List of devices attached
emulator-5554 device
8. Run react-native-template-typescript project
React Nativeの実行はプロジェクト直下で「react-native run-android」のコマンド一発。
起動中の仮想モバイルデバイスのIDに対しての操作が標準出力に流れて表示。
