Technical Implementation

Composables Used

• useWebSocket() - Connection management, auto-reconnect
• useGameActions() - Type-safe action emitters
• useGameStore() - Game state and play history

Store Integration

// Game state computed from store
const gameState = computed(() => gameStore.gameState)
const playHistory = computed(() => gameStore.playHistory)
const canRollDice = computed(() => gameStore.canRollDice)

// Runners state conversion
const runnersState = computed(() => ({
  first: gameState.value?.runners.first !== null,
  second: gameState.value?.runners.second !== null,
  third: gameState.value?.runners.third !== null
}))

WebSocket Lifecycle

onMounted(() => {
  connect()  // Establish connection

  watch(isConnected, async (connected) => {
    if (connected) {
      await actions.joinGame('player')
      await actions.requestGameState()
    }
  })
})

onUnmounted(() => {
  actions.leaveGame()
  gameStore.resetGame()
})

Next Steps (Phase F3)

Phase F3: Decision Input Workflow (Week 3)

Now that game state displays beautifully, we need to add interactive decision inputs:

1. Defensive positioning - Infield/outfield depth selection
2. Pitcher focus - Targeting specific hitters
3. Stolen base attempts - Per-runner SB toggles
4. Offensive approach - Swing/bunt/hit-and-run
5. Turn indicators - Whose decision is needed
6. Decision validation - Client-side checks before submit
7. Mobile-friendly forms - Large buttons, clear labels

Components to Create:

• components/Decisions/DefensiveSetup.vue
• components/Decisions/PitcherFocusInput.vue
• components/Decisions/StolenBaseInputs.vue
• components/Decisions/OffensiveApproach.vue
• components/Decisions/DecisionPanel.vue
• components/UI/ActionButton.vue
• components/UI/ButtonGroup.vue

Estimated Time: 4-6 hours

Lessons Learned

1. Mobile-first saves time - Designing for mobile first makes desktop scaling easier
2. Gradients add polish - Simple gradients make UI feel modern without heavy assets
3. Animations enhance UX - Subtle pulse/fade effects make UI feel alive
4. Color coding works - Green (runs), Red (outs), Blue (hits) intuitive
5. Empty states matter - Friendly messages improve first-time experience
6. Sticky scoreboard is gold - Always-visible context improves gameplay

Known Issues

Toast Notification Positioning Bug

Issue: Toast notifications only render when positioned at screen center (top-1/2, left-1/2). Bottom positioning fails silently.

Symptoms:

• ✅ Works: fixed top-1/2 left-1/2 -translate-x-1/2 -translate-y-1/2
• ❌ Fails: fixed bottom-8 left-1/2 -translate-x-1/2
• ❌ Fails: Using <Transition> wrapper around toast div

Attempted Solutions:

• Changed z-index from 50 → 100 → 9999 (no effect)
• Removed Transition wrapper (still fails at bottom)
• Changed positioning units (px, rem, vh - all fail)
• Verified v-if toastMessage reactive state (works)
• Console logs show toast state active (works)

Root Cause: Unknown - possibly Tailwind transform conflict, Nuxt SSR hydration issue, or viewport calculation bug

Current Workaround:

• Demo page uses center-screen position (working)
• Production components should implement UI store toast system instead
• File: frontend-sba/pages/demo.vue:165-177

Priority: Low (demo-only issue, not affecting production components)

Next Steps for Fix:

1. Test with Pinia UI store toast system
2. Try absolute positioning instead of fixed
3. Debug with browser DevTools element inspector
4. Check if <Teleport> to body helps

---

Status: ✅ Phase F2 Complete - Ready for Phase F3 (with known toast positioning bug documented) Next Session: Implement decision input workflow Backend Integration: Ready (730/731 tests passing, all WebSocket handlers complete) Frontend Progress: Phase F1 (70%) + Phase F2 (100%) = ~85% through Week 2 goals
