πŸ‘©β€πŸ’»πŸ‘¨β€πŸ’»β€ Run / Compile it locally

Setup your React Native environment by following the Getting started guide (React Native CLI Quickstart).

After cloning the project, initialize its node environment, compile the TypeScript and finally the native version:

$> yarn
$> tsc

# then for iOS
$> cd ios
$> pod install
$> cd ..
$> react-native run-ios

# or for Android - make sure to have your emulator running or phone connected in developer mode
$> react-native run-android

To get an insight into the redux action flow, state and log, use react-native-debugger
and the Debug mode via React Native's shaking menu.

To let it use your local docker development environment instead of production endpoints, set PRODUCTION to false in the configuration file.

πŸ‘¨β€πŸ’»β€πŸ‘©β€πŸ’» Run the E2E tests

Setup your detox environment by following the Step 1 of detox's documentation.

Afterwards, first compile the test version (only needed once per native breaking change) and start the tests afterwards:

$> detox build --configuration ios.sim.debug
$> detox test --configuration ios.sim.debug

πŸ€” Personal ToDos

  • Should have

    • Optimize and benchmark rendering
    • Android
      • Camera, when first blocking permissions, going to settings, granting them, return -> overlay stays visible
      • Map markers on location selector scene is lagging behind movement
    • Reflect REQUEST_ERROR errors in the seperate UIs instead of silently canceling the loading/sending
    • Pull conversation again when open and coming from background to make sure its marked as read
    • Notifications after background pull / detect new conversations - even pull pull conversations? Delta algo!
    • Handle WebSocket reconnect after long inactivity
  • Nice to have

    • Make sure there is no gap between old store and long-time-no-see message list request -> hotfix: logout-in
    • Deep linking via apple-app-site-association, needs to be merged to fs master & production
    • Settings screen to setup background pull / notifications?
    • Use CONVERSATIONS_SUCCESS to warm up conversation's message (at least one)
    • State for loading conversations overview for loading indicator
  • Feature creep

    • Edit profile information / MΓΌtze :)
