Version History

Development Phase (Pre-1.0)

The project evolved through several iterations:

1. Initial Concept: Basic Netflix HTML parsing
2. Turkish Localization: Added Turkish UI text removal
3. Dual-Mode Architecture: Implemented static + headless fallback
4. Modular Design: Separated concerns into dedicated modules
5. Production Ready: Comprehensive testing and documentation

Key Technical Decisions

• ES6+ Modules: Modern JavaScript with import/export
• Static-First Strategy: Prioritize performance over completeness
• Graceful Degradation: Continue operation when optional deps fail
• Minimal Polyfills: Targeted compatibility layer for Node.js
• Comprehensive Testing: Live data testing with real Netflix pages
• Documentation-First: Extensive documentation for future maintainers

Breaking Changes from Development

• Function renamed from fetchNetflixMeta → scraperNetflix
• normalizeNetflixUrl integrated into main function
• Polyfill approach simplified for Node.js 24+ compatibility
• Error messages localized to Turkish
• Module structure reorganized for better maintainability

Migration Guide

For Users Upgrading from Development Versions

If you were using early development versions:

// Old API (development)
import { fetchNetflixMeta, normalizeNetflixUrl } from 'flixscaper';

const normalized = normalizeNetflixUrl(url);
const result = await fetchNetflixMeta(normalized);

// New API (1.0.0)
import { scraperNetflix } from 'flixscaper';

const result = await scraperNetflix(url);

Key Changes

1. Single Function: scraperNetflix handles everything
2. Integrated Normalization: No separate URL normalization function
3. Better Error Messages: Turkish error messages for Turkish users
4. Improved Performance: Optimized static parsing
5. Better Documentation: Complete API and architectural documentation
