Expo for Professionals
Expo developers include a wide variety of people making apps with Expo in different ways. To learn more about the most popular apps made with Expo we talked to developers and looked at production apps and found that most of them are made by professionals as part of a business. People who use Expo for business use it sometimes everyday and rely on it in part for their livelihoods as professional pr
You can now use Expo APIs in any React Native app
Note: this post was originally published on February 28, 2019, and subsequently updated on March 14, 2019 to reflect improvements to the workflow. Starting today, you can use as little or as much of the Expo SDK as you like in any React Native app. We’ve spent a lot of time building and maintaining these cross-platform APIs for native features, and we’re happy to finally share them with the entire
Image Compression with Expo CLI
Images often take up the most space out of any asset type in mobile apps given how prevalent they are and how large they can be. At Expo, we want to help you optimize your apps as much as possible to speed up download times and decrease storage space for your end users. That’s why we’re excited to announce that we’re bringing asset optimization to Expo CLI starting with PNGs and JPEGs! With the ne
Testing Expo Apps with Detox and react-native-testing-library
Update: For information on how to setup and configure Detox in an Expo project, see our documentation. Expo helps you build and ship features incredibly quickly. But you can’t ship quickly if you don’t know whether your app is broken. Luckily, there are some great React Native testing tools that can help us: Detox for end-to-end testing and react-native-testing-library for component testing. We’ll
Create a Splash Screen - Expo Documentation
A splash screen, also known as a launch screen, is the first screen that a user sees when opening your app, and it stays visible while the app is loading. You can control when the splash screen disappears by using the AppLoading component or SplashScreen module. The default splash screen is a blank white screen. This might work for you, if it does, you're in luck! If not, you're also in luck becau
expo detachとreact-native initにおける比較 - Qiita
何をやったのか $ react-native initと$ exp detachでできたアプリについて比較を行った。 ちなみに、以下の記事の続きみたいな感じです。 Expo detachから各シミュレーター起動まで そもそもなぜ Detachするのか? Expo公式のドキュメントにも書いてあるが、Expoがデフォルトで対応していないNativeの機能を追加したい時に、初めてDetachする。ただしこれによって、しなければならないことは以下の通り。 アプリのStand alone化の際には、Document通りにはできず自力でやらなければならない NativeCodeの実装 (特にデフォルト対応のPush通知だけはDetachによってサポートされなくなるので、自力でNative実装が必要) ReactNativeのVersion上げに対するBreaking Changesも、自力対応しなけれ
Expo ではじめる ReactNative 開発環境 - Qiita
某所で調べた資料 Expo とは ReactNative上で、JS のみで ios/android アプリを作る開発/ビルド環境。ネイティブプラグインが使えないという縛りを受け入れることで、アプリをQRコード経由で簡単に公開したり、共有したりできる。 ios/android のコードを書かなくていい、というか一切書けない。 参考: expo.ioを使ってリアルタイムにReact Nativeアプリを開発する http://amagitakayosi.hatenablog.com/entry/2017/04/18/120000 Hello World $ npm install -g exp $ exp init my-native-app $ exp start # 開発用ビルドの開始 $ exp build:ios # 本番用ビルド
