# Analyze bundle
npx react-native-bundle-visualizer

# Opens a visual treemap in browser showing:
# - node_modules breakdown by size
# - Your source code size
# - Duplicate modules

# Common large packages to replace:
# moment (280KB) -> date-fns tree-shaking
# lodash (full, 70KB) -> lodash-es specific imports
# FontAwesome all icons -> import only used icons

# Result: each 100KB reduction = ~50KB gzip reduction
# = faster first install + lower Play/App Store size

# Verify versions before building
cat app.json | grep '"version"'
# -> "version": "1.0.0"
# -> "versionCode": 1
# -> "buildNumber": "1"

# Build both platforms in parallel
eas build --platform ios --profile production &
eas build --platform android --profile production &
wait

# Or use the combined command:
eas build --platform all --profile production

# After builds complete, check status:
eas build:list --status finished --limit 2

// Pre-submission smoke test checklist:

// Install production build on physical device
// (not simulator — push notifications require real device)

// Test:
// [ ] Fresh install and sign up flow
// [ ] Sign out and sign in with existing account
// [ ] Core feature: create, complete, view streak
// [ ] Push notification: schedule and receive
// [ ] Background behavior: close and reopen app
// [ ] Deep links from browser/email
// [ ] Offline: airplane mode then restore network
// [ ] Landscape orientation (if not locked)
// [ ] All tabs and major screens load without crash
// [ ] Performance: no jank on FlatList scroll

# Submit to App Store (TestFlight first, then App Review)
eas submit --platform ios --latest

# Submit to Play Console (internal -> production)
eas submit --platform android --latest

# Or submit both at once:
eas submit --platform all --latest

# After submission:
# iOS: App Store Connect > App > 1.0 Prepare for Submission
#      > Add for Review > Submit to App Review
# Android: Play Console > Production > Create release
#           > Promote internal build > Review > Start rollout
