- 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)
Reduces HTTP requests from 44+ individual images to 3 sprite sheets
(~93% reduction). Includes Go sprite generator tool, CSS classes,
template integration, and E2E tests.
- Add cmd/sprites/main.go for sprite generation (60x60px + 120x120px @2x)
- Add _sprites.css with responsive sizing and retina support
- Update templates to use sprites with logoIndex fallback
- Add Makefile targets: sprites, sprites-clean
- Add 9-test E2E suite for sprite functionality
- Add doc/22-SPRITES.md with usage documentation
Implement a command palette accessible via CMD+K/Ctrl+K using the ninja-keys
web component. Features include:
- New /api/cmd-k endpoint serving dynamic CV entries (experiences, projects, courses)
- Language-aware responses with 1-hour cache headers
- Scroll-to-section functionality for quick navigation
- Enhanced keyboard shortcuts modal with CMD+K documentation
- Comprehensive test coverage for API and UI interactions
Also includes cleanup of deprecated debug test files and various UI polish
improvements to contact form, themes, and action bar components.
- Move all bilingual text from templates to UI JSON (labels, buttons, modals)
- Move skills summary paragraph to CV JSON with HTML support
- Add new UI sections: navigation, viewControls, sections, footer, portfolio,
pdfModal, shortcutsModal, infoModal, widgets
- Update Go structs to match expanded JSON structure
- Add template.HTML type for CV.SkillsSummary field
- Add JSON content validation test (70-json-content-validation.test.mjs)
Templates now contain only structural logic (CSS classes, HTML attributes)
while all user-visible text loads from JSON files for proper i18n support.
Part 1: Shared Utilities
- Create internal/fileutil package with FindDataFile() and LoadJSON()
- Create internal/lang package with language constants and validation
- Eliminate 46 lines of code duplication between cv/loader.go and ui/loader.go
- Simplify cv/loader.go from 69 to 36 lines (-48%)
- Simplify ui/loader.go from 56 to 24 lines (-57%)
Part 2: Validation Layer
- Add comprehensive validation in internal/models/cv/validation.go
- Validate Personal (name, email format, URLs)
- Validate Experience (required fields, dates)
- Validate Education (required fields)
- Validate Skills (proficiency ranges 1-5, categories)
- Validate Languages (proficiency levels 1-5)
- Validate Projects (title, URLs)
- Validate Meta (version, language)
- Integrate validation into LoadCV() - automatic on load
- Create ValidationError and ValidationErrors types for clear error reporting
- Report all validation errors at once (better UX)
Testing:
- Add comprehensive tests for fileutil package (FindDataFile, LoadJSON)
- Add tests for lang package (IsValid, Validate, All)
- Add 280+ validation test cases covering edge cases
- All tests pass with real CV data (cv-en.json, cv-es.json)
- Fixed validation to allow both URLs and local paths for gitRepoUrl
Documentation:
- Create _go-learning/refactorings/002-shared-utilities-validation.md
- Document architecture, benefits, testing, and interview talking points
- Explain WHY decisions were made (DRY, type safety, data integrity)
Benefits:
- DRY: Single source of truth for utilities
- Type safety: Language constants instead of magic strings
- Data integrity: Validation catches errors at load time
- Better errors: Clear messages showing all issues at once
- Maintainability: Centralized utilities easier to update
