Debugging Protocols

Logging system changes

1import { ref, watch } from 'vue'
2
3const oxygenLevel = ref(98.5)
4
5// Change monitoring
6watch(oxygenLevel, (newLevel, oldLevel) => {
7  console.log(`⚠️ Oxygen level: ${oldLevel}% → ${newLevel}%`)
8
9  if (newLevel < 90) {
10    console.error('🚨 ALERT: Low oxygen level!')
11  }
12})

Debug in template

1<template>
2  <!-- Diagnostic panel -->
3  <div v-if="debugMode" class="debug-panel">
4    <pre>{{ JSON.stringify(systemData, null, 2) }}</pre>
5  </div>
6
7  <!-- Critical indicators -->
8  <div class="critical-systems">
9    <span>O2: {{ oxygen }}%</span>
10    <span>Temp: {{ temperature }}°C</span>
11    <span>Pressure: {{ pressure }} hPa</span>
12  </div>
13</template>
