React Nativeでアプリケーションをつくってみる

現在エンジニア歴4ヶ月の私ですが、勉強にきょうからコツコツアプリをつくっていきます。
その備忘録を残していきます。

最初はExpoの立ち上げから

Expoドキュメント

npx create-expo-app --template
create-expo-app@3.2.0
Ok to proceed? (y)  
  • yesを選択



 Choose a template: › - Use arrow-keys. Return to submit.
    Default
    includes tools recommended for most app developers
    Blank
  ❯ Blank (TypeScript)
    Navigation (TypeScript)
    Blank (Bare)
  • Blank (TypeScript)を選択


What is your app named?
  • 任意の名前 

- cd my-app
- npm run android
- npm run ios
- npm run web
  • 作成したディレクトリに移動して立ち上げたいコマンドを実行 

または

npx expo start

スマホにExpoアプリをダウンロードしておき
コマンド実行後、ExpoアプリからQRを読み取ると立ち上がります。
