feat: Add VPS storage system and complete integration
🎯 Overview: Implemented complete VPS-based storage system allowing the iOS app to download and store manga chapters on the VPS for ad-free offline reading. 📦 Backend Changes: - Added storage.js service for managing chapter downloads (270 lines) - Updated server.js with 6 new storage endpoints: - POST /api/download - Download chapters to VPS - GET /api/storage/chapters/:mangaSlug - List downloaded chapters - GET /api/storage/chapter/:mangaSlug/:chapterNumber - Check download status - GET /api/storage/image/:mangaSlug/:chapterNumber/:pageIndex - Serve images - DELETE /api/storage/chapter/:mangaSlug/:chapterNumber - Delete chapters - GET /api/storage/stats - Get storage statistics - Fixed scraper.js Puppeteer compatibility issues (waitForTimeout, networkidle0) - Added comprehensive test suite: - test-vps-flow.js (13 tests - 100% pass rate) - test-concurrent-downloads.js (10 tests for parallel operations) - run-tests.sh automation script 📱 iOS App Changes: - Created APIConfig.swift with VPS connection settings - Created VPSAPIClient.swift service (727 lines) for backend communication - Updated MangaDetailView.swift with VPS download integration: - Cloud icon for VPS-available chapters - Upload button to download chapters to VPS - Progress indicators for active downloads - Bulk download options (last 10 or all chapters) - Updated ReaderView.swift to load images from VPS first - Progressive enhancement: app works without VPS, enhances when available ✅ Tests: - All 13 VPS flow tests passing (100%) - Tests verify: scraping, downloading, storage, serving, deletion, stats - Chapter 789 download test: 21 images, 4.68 MB - Concurrent download tests verify no race conditions 🔧 Configuration: - VPS URL: https://gitea.cbcren.online:3001 - Storage location: /home/ren/ios/MangaReader/storage/ - Static file serving: /storage path 📚 Documentation: - Added VPS_INTEGRATION_SUMMARY.md - Complete feature overview - Added CHANGES.md - Detailed code changes reference - Added TEST_README.md, TEST_QUICK_START.md, TEST_SUMMARY.md - Added APIConfig README with usage examples 🤖 Generated with Claude Code (https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
