Story 3.3: Connect Download Button to PDF Generation

Status: done

Story

As a user, I want to click the download button and get my PDF, so that I can use my resume for job applications.

Acceptance Criteria

  1. AC1: Given I click the download button, when PDF generation starts, then the button shows loading spinner
  2. AC2: The button is disabled during PDF generation
  3. AC3: Given PDF generation succeeds, when the PDF is ready, then the browser downloads the file
  4. AC4: Downloaded filename is "Ali_Arghyani_Resume.pdf"
  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
  7. AC7: Button returns to normal state after error
  8. AC8: Button works correctly after error (can retry)

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>
