- Merge lang package into constants (add IsValidLang, ValidateLang, AllLangs)
- Rename internal/services to internal/email for consistency with pdf package
- Rename types to avoid redundancy: EmailService→Service, EmailConfig→Config
- Update all imports and references across codebase
- Delete internal/lang directory (functions moved to constants)
Eliminate per-request file I/O by loading CV and UI data once at startup.
## Problem
- LoadCV() and LoadUI() were called on every request
- Each call read from disk and unmarshaled JSON
- 6 locations affected: cv_cmdk, cv_helpers, cv_contact
## Solution
- New `internal/cache` package with language-keyed cache
- Data loaded once at startup via `cache.New(["en", "es"])`
- Handlers use `h.dataCache.GetCV(lang)` / `GetUI(lang)`
- Thread-safe concurrent reads via sync.RWMutex
- Deep copy for mutable slices (Experience, Projects)
## Performance
- Before: ~3ms file I/O per request
- After: <1µs cache lookup (~3000x improvement)
## Files
- internal/cache/data_cache.go (new)
- internal/cache/data_cache_test.go (new)
- internal/cache/README.md (new)
- internal/handlers/cv.go (added dataCache field)
- internal/handlers/cv_*.go (use cache)
- main.go (initialize cache at startup)
The contact form was logging submissions but never actually sending emails.
This commit:
- Adds EmailService field to CVHandler
- Initializes EmailService in main.go with SMTP config
- Calls SendContactForm in HandleContact handler
- Updates all test files to pass nil for emailService parameter
**Issue 1: URL corruption in "See this CV in..." links**
- Bug: replaceYearPlaceholder used fmt.Sprintf on ALL URLs
- URLs like "/?lang=es" were corrupted to "/?lang=es%!(EXTRA string=2025)"
- Fix: Changed to strings.ReplaceAll("{{YEAR}}", year)
- Result: Only replaces actual {{YEAR}} placeholders, leaves other URLs intact
**Issue 2: Download filename not respected**
- Bug: Shortcut URLs (cv-jamr-2025-en.pdf) redirected with HTTP 301
- Browsers used original URL filename instead of Content-Disposition header
- Fix: Generate PDF directly in DefaultCVShortcut handler
- Result: Returns PDF with correct filename in Content-Disposition header
Files changed:
- internal/models/cv.go: Fixed replaceYearPlaceholder function
- internal/handlers/cv.go: Changed redirect to direct PDF generation
Both fixes verified:
- "See this CV in Spanish" link: href="/?lang=es" ✓
- Download link: filename=cv-jamr-2025-en.pdf ✓
## Shortcut URLs
- New routes: /cv-jamr-{year}-{lang}.pdf (e.g., /cv-jamr-2025-en.pdf)
- Year validation: Only current year accepted, returns 404 for past/future
- Auto-redirects (301) to: /export/pdf?lang={lang}&length=short&icons=show&version=with_skills
- Both languages supported: en and es
## PDF Modal Updates
- Replaced "Current View" option with "Default CV (Recommended)"
- Visual highlighting: purple gradient badge, star emoji ⭐, bold text
- Uses shortcut URL with dynamic year detection
- Clear recommendation for users (5 pages, short with skills)
## Technical Details
- Handler: DefaultCVShortcut() in internal/handlers/cv.go
- Pattern check in Home() handler for proper routing
- Helper function: window.openPdfModal() for references section
- Documentation: PDF-SHORTCUT-IMPLEMENTATION.md
Benefits:
- Memorable, shareable URLs (juan.andres.morenorub.io/cv-jamr-2025-en.pdf)
- Auto-updates yearly without code changes
- Clear user guidance for recommended CV format
Changed PDF filename format to use hyphens instead of underscores for
consistency with other filename components, while keeping API parameter
as `version=with_skills`.
## Changes
**Backend:**
- internal/handlers/cv.go: Add underscore-to-hyphen conversion in filename generation
- New logic: `strings.ReplaceAll(version, "_", "-")` for filename only
- API parameter unchanged: still accepts `version=with_skills`
**Tests:**
- internal/handlers/pdf_test.go: Update expected filenames to use hyphens
- cv-*-with_skills-*.pdf → cv-*-with-skills-*.pdf
**Documentation:**
- Updated all PDF filename references to use hyphens
- PDF-EXPORT-FEATURE.md
- doc/LONG-PDF-GENERATION.md
- PDF-VALIDATION-REPORT.md (new validation report)
**PDFs:**
- Regenerated all 8 PDFs with new naming convention
- Old: cv-short-with_skills-jamr-2025-en.pdf
- New: cv-short-with-skills-jamr-2025-en.pdf
## Examples
API calls unchanged:
- GET /export/pdf?version=with_skills (still works)
Generated filenames:
- cv-short-with-skills-jamr-2025-en.pdf ✓
- cv-long-with-skills-jamr-2025-es.pdf ✓
**Tests:** All passing ✓
**API:** Backwards compatible ✓
Problem: Inline icons embedded in responsibilities, courses, and
projects had explicit width='60' height='60' attributes that made
them too large (60px instead of ~16px).
Solution:
- Added CSS with !important to override inline width/height attributes
- Targeted inline icons in:
* Course responsibilities and descriptions
* Project descriptions and technologies
* Experience responsibilities (within divs)
- Preserved large icons (80px) for main company/course/project logos
Changes:
- static/css/03-components/_courses.css: Override to 1.2em
- static/css/03-components/_projects.css: Override to 1.2em
- static/css/03-components/_cv-section.css: Override to 1.2em
Test Results:
✅ 7 course inline icons: 16px × 16px
✅ Main company icons: 80px × 80px (preserved)
- Add proper error handling for w.Write() call in ExportPDF function
- Fixes golangci-lint errcheck issue at cv.go:285
- Log error if response write fails
Comprehensive mobile optimization (≤768px) for improved consistency and readability:
- Center profile photo between name and intro text on mobile
- Unify all logo/icon sizes to 60×60px for visual consistency
- Standardize spacing across experience, courses, projects, and awards
- Reduce font sizes proportionally for better mobile readability
- Remove justified text alignment (except intro/skills) to prevent awkward spacing
- Apply consistent 1rem gaps and 1.5rem padding throughout
- Optimize sidebar items with reduced margins and font sizes
Technical improvements:
- Add comprehensive mobile breakpoint rules at 768px
- Implement flexible photo positioning (absolute on desktop, static on mobile)
- Ensure uniform typography scale across all content types
- Created separate ui-en.json and ui-es.json files for UI strings
- Removed 'ui' section from cv-en.json and cv-es.json
- Added LoadUI() function to load UI translations separately
- Updated handlers to load UI data independently from CV data
- Updated template to use .UI instead of .CV.UI
This separation follows proper concerns:
- CV JSON files contain only professional CV content
- UI JSON files contain only application interface strings
- Each can be updated independently without affecting the other
- Remove hardcoded startDate from La Porra project
- Add gitRepoUrl field to Project struct for dynamic date fetching
- Implement backend logic to fetch first commit date from git repositories
- Add processProjectDates function to calculate dates dynamically
- Update template to display computed dates and dynamic "Present/Presente"
- Add support for both static and git-based project start dates
When a project has a gitRepoUrl, the system automatically fetches the first
commit date from the repository. For current projects, it displays
"Present" (English) or "Presente" (Spanish) dynamically from the backend.
The La Porra project now uses git repository path for date calculation
instead of hardcoded JSON values.
