# Epic Technical Specification: Resume Preview Page

Date: 2025-11-30  
Author: mahdi  
Epic ID: 2  
Status: **REVISED** (Post UX Validation)  
Last Update: 2025-11-30 (Winston - Architect)

---

## Overview

Epic 2 delivers the Resume Preview Page - a pixel-perfect, standalone web page at `/resume` that renders the resume exactly as it will appear in the PDF export. This epic creates the visual foundation of the Resume Export feature, implementing all UI components with a **single-column layout** using the Blue & White Clean Professional design template.

The preview page serves dual purposes: (1) user-facing preview for verification before download, and (2) source page for server-side PDF generation via Puppeteer. The WYSIWYG (What You See Is What You Get) approach ensures perfect consistency between web and PDF output.

**Design Template Reference:** `design templates/Blue and White Clean and Professional Resume.png`

## Objectives and Scope

**In Scope:**
- Standalone `/resume` route with no site navigation
- **Single-column vertical layout** with A4-proportioned container
- Five modular Vue components for resume sections
- Blue (#2563eb) and white color scheme with Inter typography
- Blue uppercase section headers with bottom border
- Profile photo display in header
- Print-optimized CSS for PDF generation compatibility
- A4 aspect ratio container (210mm × 297mm)
- Floating download button (hidden in print mode via `?print=true`)
- ATS-compatible HTML structure (semantic headings, no layout tables)

**Out of Scope:**
- PDF generation logic (Epic 3)
- Resume data creation (Epic 1 - already completed)
- Persian language support (future)
- Multiple template designs (future)
- Customization UI (future)

## System Architecture Alignment

**Framework:** Nuxt 4.1.3 with Vue 3 Composition API  
**Styling:** Tailwind CSS 4.1.x with Nuxt UI 4.0.x components  
**Fonts:** Inter (via @nuxt/fonts) for English text  
**Icons:** Nuxt UI Icon component with Iconify icons  

**Architecture Decisions Referenced:**
- ADR-002: Vue Components as Templates - Each resume section is a standalone component
- Novel Pattern: WYSIWYG PDF Export - Single component source for web and PDF
- Naming Conventions: PascalCase for components, Tailwind utilities for styling

**Data Source:** `useResumeData()` composable (from Epic 1) provides reactive access to `app/data/resume.en.ts`

## Detailed Design

### Services and Modules

| Component | Responsibility | Inputs | Outputs | Owner |
|-----------|---------------|--------|---------|-------|
| `pages/resume.vue` | Route handler, layout wrapper | Query param `?print` | Renders ResumePreview | Story 2.1 |
| `ResumePreview.vue` | Container, single-column layout | Resume data | Full resume layout | Story 2.2 |
| `ResumeHeader.vue` | Photo + Name + Contact Info | `basics` (name, label, email, phone, location, url, image) | Header section | Story 2.3 |
| `ResumeSummary.vue` | Professional summary | `basics.summary` | Summary section | Story 2.3 |
| `ResumeExperience.vue` | Work history with highlights | `work[]` array | Experience section | Story 2.3 |
| `ResumeEducation.vue` | Education history | `education[]` array | Education section | Story 2.4 |
| `ResumeAdditionalInfo.vue` | Skills + Languages + Certs | `skills[]`, `languages[]`, `certificates[]` | Additional Info section | Story 2.4 |
| `ResumeDownloadButton.vue` | Floating action button | `?print` query param | Download trigger | Story 2.5 |

**Removed Components (vs. Previous Draft):**
- `ResumeContact.vue` - Merged into `ResumeHeader.vue`
- `ResumeSkills.vue` - Merged into `ResumeAdditionalInfo.vue`
- `ResumeLanguages.vue` - Merged into `ResumeAdditionalInfo.vue`

### Data Models and Contracts

**Input:** All components consume data from `useResumeData()` composable:

```typescript
const { resume, formatDate, getFullName, getPdfFilename } = useResumeData()
```

**Resume Data Structure (from Epic 1):**
- `resume.basics`: Name, label, email, phone, location, url, image, summary
- `resume.work[]`: Company, position, startDate, endDate, highlights[]
- `resume.education[]`: Institution, area, studyType, startDate, endDate
- `resume.skills[]`: Name (category), keywords[]
- `resume.languages[]`: Language, fluency
- `resume.certificates[]`: Name, date, issuer (optional)
- `resume.awards[]`: Title, date, awarder, summary (optional)

**Date Format:** YYYY-MM strings formatted to "Jan 2023" via `formatDate()` helper

### APIs and Interfaces

**Component Props:**

```typescript
// ResumePreview.vue - No props (uses composable)
// All child components receive data via props from parent

// ResumeHeader.vue
interface Props {
  name: string
  label: string  // Job title
  email: string
  phone: string
  location: string
  url: string
  image?: string  // Profile photo URL
}

// ResumeSummary.vue
interface Props {
  summary: string
}

// ResumeExperience.vue
interface Props {
  work: WorkExperience[]
}

// ResumeEducation.vue
interface Props {
  education: Education[]
}

// ResumeAdditionalInfo.vue
interface Props {
  skills: Skill[]
  languages: Language[]
  certificates?: Certificate[]
  awards?: Award[]
}

// ResumeDownloadButton.vue
interface Props {
  isPrintMode: boolean
}
```

**Query Parameters:**
- `?print=true`: Hides download button, optimizes for PDF generation

### Workflows and Sequencing

**User Flow:**
1. User navigates to `/resume`
2. Page loads with `layout: false` (standalone)
3. `ResumePreview.vue` fetches data via `useResumeData()`
4. Single-column layout renders in order:
   - Header (Photo + Name + Contact Info)
   - Summary
   - Experience
   - Education
   - Additional Information (Skills, Languages, Certs)
5. Floating download button appears (bottom-right)
6. User clicks download → triggers Epic 3 PDF generation

**PDF Generation Flow (Epic 3 integration):**
1. Puppeteer navigates to `/resume?print=true`
2. Same components render without download button
3. Puppeteer captures page as PDF
4. Result: Pixel-perfect match to web preview

## Non-Functional Requirements

### Performance

- **Page Load:** < 1 second (static data, no API calls)
- **LCP (Largest Contentful Paint):** < 1.5s
- **CLS (Cumulative Layout Shift):** 0 (fixed dimensions)
- **Font Loading:** Inter font preloaded via @nuxt/fonts

**Strategy:** Inline critical CSS, use Tailwind JIT, no external API dependencies

### Security

- **No PII Exposure:** Resume data is static, no user input
- **SEO:** `noindex` meta tag for privacy (resume not indexed by search engines)
- **XSS Protection:** Vue's automatic escaping for all text content

### Reliability/Availability

- **Static Rendering:** Page works without JavaScript (SSR)
- **Graceful Degradation:** Print styles work even if JS fails
- **Error Handling:** Composable returns empty data if file missing (prevents crashes)

### Observability

- **Console Logging:** Development mode logs component mount/unmount
- **Error Boundaries:** Vue error handlers catch component failures
- **Performance Monitoring:** Nuxt DevTools tracks component render times

## Dependencies and Integrations

**External Dependencies:**
- `@nuxt/fonts` (0.11.x): Inter font loading
- `@nuxt/ui` (4.0.x): UButton, UIcon components
- Tailwind CSS (4.1.x): Utility classes

**Internal Dependencies:**
- `app/types/resume.ts`: TypeScript interfaces (Epic 1)
- `app/data/resume.en.ts`: Resume data (Epic 1)
- `app/composables/useResumeData.ts`: Data access composable (Epic 1)

**Integration Points:**
- Epic 3: `/api/resume/pdf` will navigate to `/resume?print=true`
- Future: Persian support will use `app/data/resume.fa.ts`

## Acceptance Criteria (Authoritative)

### AC1: Standalone Resume Route
**Given** I navigate to `/resume`  
**When** the page loads  
**Then** I see the resume preview with no site header/footer

**And** "Languages:" with fluency levels (e.g., "English, Malay, Japan")  
**And** "Certifications:" (if present) with name and issuer  
**And** "Awards/Activities:" (if present) with brief descriptions

### AC10: Download Button
**Given** I'm on the resume page  
**When** I view the page  
**Then** I see a floating action button in bottom-right corner  
**And** it has download icon (i-heroicons-arrow-down-tray)  
**And** it has "Download PDF" text  
**And** it has blue background color (#2563eb)  
**And** it has fixed position (doesn't scroll)  
**And** it has shadow for elevation  
**And** it has `.no-print` class

### AC11: Print Mode
**Given** I navigate to `/resume?print=true`  
**When** the page loads  
**Then** the download button is not visible  
**And** all other content renders normally

### AC12: Print Styles

**And** text is bold (font-weight: 700)  
**And** has a blue bottom border (border-bottom: 2px solid #2563eb)  
**And** has appropriate margin/padding for visual separation

### AC14: ATS Compatibility
**Given** the HTML structure is inspected  
**When** I check semantic elements  
**Then** name uses `<h1>` tag  
**And** section headers use `<h2>` tags  
**And** no layout tables are used (CSS Grid/Flexbox only)  
**And** all text is real HTML text (not images)

## Traceability Mapping

| AC14 | ATS Compatibility | HTML structure | Inspect DOM, verify semantic tags, no tables |

## Risks, Assumptions, Open Questions

**Risks:**
- **Risk:** Font loading delay causes layout shift
  - **Mitigation:** Use @nuxt/fonts with preload, font-display: swap
- **Risk:** Print styles differ across browsers
  - **Mitigation:** Test in Chrome, Firefox, Safari; use Puppeteer for PDF (consistent)
- **Risk:** Long content causes page overflow
  - **Mitigation:** Test with max content length, add overflow handling
- **Risk:** Profile image not provided or fails to load
  - **Mitigation:** Implement graceful fallback (hide image container, expand text area)

**Assumptions:**
- **Assumption:** Inter font is ATS-compatible
  - **Validation:** Inter is a standard web font, widely supported
- **Assumption:** Single-column layout works for all content lengths
  - **Validation:** Test with varying experience entries (2-5 jobs), education (1-3 degrees)
- **Assumption:** Blue (#2563eb) has sufficient contrast
  - **Validation:** WCAG AA contrast ratio verified (4.5:1 minimum)

**Open Questions:**
- **Question:** Should mobile view show download button?
  - **Answer:** Yes, but consider smaller size or icon-only
- **Question:** How to handle very long job titles or company names?
  - **Answer:** Use text truncation with ellipsis, test with max lengths
- **Question:** Profile photo aspect ratio and size?
  - **Answer:** Square or portrait (3:4), max 150px width, left-aligned in header

## Test Strategy Summary

**Unit Tests:**
- Each component renders with sample data
- Date formatting helper works correctly
- Composable returns expected data structure
- Profile image fallback works when image unavailable

**Integration Tests:**
- Full page renders with all components in correct order
- Print mode hides download button
- Responsive layout adapts spacing on mobile

**Visual Regression Tests:**
- Screenshot comparison: web preview vs design template
- Print preview matches web preview
- Mobile layout matches design intent

**Manual Tests:**
- Navigate to /resume, verify all sections in correct order
- Click all links (email, phone, website)
- Test print preview (Ctrl+P)
- Test on mobile device
- Verify ATS compatibility (copy/paste text from PDF)
- Test with and without profile photo

**Performance Tests:**
- Measure page load time (< 1s target)
- Check LCP and CLS metrics
- Verify font loading doesn't block render

**Acceptance Tests:**
- Run through all 14 ACs with real data
- Verify pixel-perfect match to design template
- Confirm Epic 3 can generate PDF from this page
