CRNA と Expo
{ "expo": { "sdkVersion": "18.0.0" } } { "expo": {
"name": "18", "description": "An empty new project", "slug": "18", "privacy": "public", "sdkVersion": "18.0.0", "version": "1.0.0", "orientation": "portrait", "primaryColor": "#cccccc", "icon": "./assets/icons/app.png", "loading": { "icon": "./assets/icons/loading.png", "hideExponentText": false }, "packagerOpts": { "assetExts": ["ttf", "mp4"] }, "ios": { "supportsTablet": true } } } CRNA Expo

Expo の欠点
Native Modules が使えない
expo で使えるnpm packageか?
Check npm package • README.md • Getting Started • Installation
• $react-native link • $rnpm link
Check source code
Check peerDependencies (package.json) "peerDependencies": { "react-native": ">=0.43.0", "react": ">=16.0.0-alpha.3", "react-native-vector-icons":
"~4.1.1" },
OK • @expo/vector-icons • react-native-branch • react-native-fbads • react-native-maps •
react-native-svg
どうしても途中で Native Modulesが必要に
$exp detach
$exp detach • ExpoKitとしてExpoのライブラリの機能は使える • Push Notificationsとかはダメ • Expo XDEは一応使える
• react-native run-ios でええやん • exp publishでテスト不可に • XCode/Android Studioでビルド
OAuthとか
None
Deep link
Deep link import { Linking } from 'react-native'; const LINK_URI
= Expo.Constants.linkingUri; : componentDidMount() { Linking.addEventListener('url', this._lnk.bind(this)); } _lnk(event) { let queryString = event.url.replace(LINK_URI, ''); const responseObj = qs.parse(queryString); const code = responseObj.code; this.getToken(code).then(…) }
Deeplink on Real device (app.json) "expo":{ "scheme": "qani" }
Expo.Constants.linkingUri • expo app内 • exp://exp.host/@pchw/*****/+ • Standalone Apps •
qani://+
None
ビルド→実機チェック→ストア申請
ビルド Building Standalone Apps
Configure app.json(iOS ver) "name": "foo", "icon": "http://Ͳ͔ͬ.com", "version": “0.0.1”, "ios":
{ "bundleIdentifier": "com.bar.foo", "buildNumber": "1" },
$npm i -g exp $exp login $exp build:ios
None
$ exp build:status
None
実機チェック
None
None
初期ロードの制約 > The very first load cannot be offline
isRemoteJSEnabled: falseは "ios": { "isRemoteJSEnabled": false, },
exp build:ios ⊇ exp publish
まとめ • Expoはとても便利 • なるべくNative Modulesを使わない • どうしてもダメなら覚悟を決めてdetach • expo上でもdeep
linkは確認できる • isJSRemoteEnabledはtrueのままの方が良い
