Commands

Install dependencies

• yarn

Dev Mode Instructions for Physical Mobile Device

Compatible with both MacOS and Windows PC for app compilation. After compilation, app can be run on either iOS or Android phone.

• Install Expo Go mobile app to run the app dev build
  • iOS
  • Android
• yarn start
  • Run app, scan QR code on physical phone

Dev Mode Instructions for Android Emulator

Compatible with both MacOS and Windows PC for app compilation.

• Note that Expo Go will be automatically installed on the emulated mobile device for you
• Create an Android Emulator AVD (simulated phone): https://developer.android.com/studio/run/managing-avds
• You need to run the Android Emulator from command line due to a bug with Vulkan
  • More info: https://developer.android.com/studio/run/emulator-troubleshooting#error:-%60vulkan-1.dll
• Command to run Android Emulator:
  • C:\Users\<username>\AppData\Local\Android\Sdk\emulator\emulator -avd <emulated phone name> -feature -Vulkan
    • Example: C:\Users\solde\AppData\Local\Android\Sdk\emulator\emulator -avd Pixel_3a_API_34_extension_level_7_x86_64 -feature -Vulkan
    • Add -no-snapshot-load flag to start emulator from "cold boot" (if emulator keeps crashing upon turning on)
• yarn a to run the app

Dev Mode Instructions for iOS Emulator

Needs MacOS for app compilation (to run XCode) / iOS Emulator.

• Note that Expo Go will be automatically installed on the emulated mobile device for you
• Documentation: https://developer.apple.com/documentation/xcode/running-your-app-in-simulator-or-on-a-device
• Should be more straightforwards than Android, you shouldn't need to use command line to open iOS emulator
• yarn i to run the app

WiFi / Tunneling (Dev Mode)

• In general, if running the app on a physical mobile device, the mobile device and the PC compiling the app should be on the same WiFi network
• If on OSU WiFi, or any other WiFi that disables peer-to-peer, use the --tunnel argument, e.g:
  • yarn start --tunnel
  • yarn i -tunnel
  • yarn a --tunnel
• Using a mobile hotspot is another potential solution, if the other WiFi networks nearby disable peer-to-peer

Login Bypass (Dev Mode)

• yarn test
  • Bypass login for testing purposes, will log you in as a dummy user "John Doe"
  • If you logged out of app, reload / restart app to automatically log back in as dummy user
  • Optional arguments:
    • --tunnel
      • For WiFi tunneling as described above
    • --ios or --android
      • For running app on iOS or Android emulator
    • Note that arguments can be combined, e.g. yarn test --android --tunnel

Prebuild Instructions for Android (Production Mode)

Compatible with both MacOS and Windows PC for building the project in Android Studio.

• yarn prebuild
• yarn android
• Steps (to be fleshed out later):
  • Open Android Studio and build APK
  • Load it onto your phone

Prebuild Instructions for iOS (Production Mode, needs MacOS)

Needs a MacOS for building the project in XCode.

• yarn prebuild
• yarn ios
• Steps (to be fleshed out later):
  • Open xcworkspace in XCode
  • Go to Product > Archive
  • View archive in folder, open package content
  • Find .app file, put in folder Payload
  • Zip Payload folder and call it <name>.ipa
  • Sideload <name>.ipa folder with AltStore

Formatting Script

• yarn pretty
  • Runs Prettier + ESLint script to catch any code formatting or linting errors
  • NOTE: This will automatically update any files with the reformatted version; if you just want to check for possible formatting issues, run yarn pretty:check (see below)
• yarn pretty:check
  • Runs Prettier + ESLint, but only reports formatting / linting issues and does not edit any files yet
  • Run via GitHub Actions in .github/workflows/main.yml, so that each PR gets its formatting / linting automatically checked before merge

App Compilation Troubleshooting

• Hot Reload is enabled by default whenever you edit a page on the app, and you can also manually trigger a reload by entering r into command line
• If reloading isn't working for some reason, double swipe up on your mobile device to exit Expo Go, and restart the app from command line

Last Year's Codebase

A different team of students worked on this projects last year, linked here for reference.

• Last year's codebase (JavaScript): https://github.com/efmmoncada/golf-drill-challenge-app
  • Check this repo's README for other useful tips on software stack
• Last year's codebase (TypeScript): https://github.com/efmmoncada/golf-app-ts
  • We are basing our codebase more on the TypeScript version from last year, but it's lacking a README
