5. AC5: Button returns to normal state after download completes
6. AC6: Given PDF generation fails, when the error occurs, then a toast notification appears

Dev Notes

Architecture Alignment

From Architecture Doc:

• Component: app/components/resume/ResumeDownloadButton.vue
• Uses useResumePdf() composable
• Uses Nuxt UI UButton with loading state

From Tech Spec Epic 3:

• AC6, AC8 map to this story
• Final integration story for Epic 3

Learnings from Previous Stories

From Story 2.5 (Status: done)

• Download button already created with placeholder handler
• Print mode detection implemented via isPrintMode prop
• Button has correct styling and position

From Story 3.2 (Status: drafted)

• useResumePdf() composable provides isGenerating and downloadPdf
• Error handling with toast notifications

Implementation Notes

Current ResumeDownloadButton.vue (from Story 2.5):

<script setup lang="ts">
interface Props {
  isPrintMode?: boolean
}

defineProps<Props>()

function handleDownload() {
  console.log('Download PDF clicked')
}
</script>

<template>
  <UButton
    v-if="!isPrintMode"
    icon="i-heroicons-arrow-down-tray"
    size="lg"
    color="primary"
    class="fixed bottom-6 right-6 shadow-lg no-print z-50"
    @click="handleDownload"
  >
    <span class="hidden sm:inline">Download PDF</span>
  </UButton>
</template>

Updated ResumeDownloadButton.vue:

<script setup lang="ts">
interface Props {
  isPrintMode?: boolean
}

defineProps<Props>()

const { isGenerating, downloadPdf } = useResumePdf()
</script>

<template>
  <UButton
    v-if="!isPrintMode"
    icon="i-heroicons-arrow-down-tray"
    size="lg"
    color="primary"
    :loading="isGenerating"
    :disabled="isGenerating"
    class="fixed bottom-6 right-6 shadow-lg no-print z-50"
    @click="downloadPdf"
  >
    <span class="hidden sm:inline">Download PDF</span>
  </UButton>
</template>
