0.4.0

v0.4.0 - Recursive Loader Extraction & True Parallel Execution

🚀 Major Features

• Loader Extraction: Build-time recursive discovery of entire component trees (including slot-based children)
• Parallel Execution: All loaders execute simultaneously, even for deeply nested components (67-100% performance improvement)
• Auto-Wrapper Pattern: Pages without loaders automatically extract child component loaders
• Zero Waterfalls: Eliminates sequential async chains for both sibling and nested components

📊 Performance Improvements

• Nested components: 67% faster (150ms → 50ms for 3-level nesting)
• Sibling components: 67% faster (150ms → 50ms for 3 siblings)
• Slot-based composition: 80% faster (250ms → 50ms for 5-level nesting)
• Direct TTFB impact: Parallel execution eliminates waterfalls - 67-80% faster server processing in typical apps

🧪 Testing & Validation

• 34 E2E tests validating parallel execution behaviour
• Performance comparison tests demonstrating waterfall elimination
• Zero-waste execution tests confirming only rendered component loaders execute

📚 Documentation

• New PERFORMANCE.md: Comprehensive guide explaining TTFB reduction, performance improvements, best practices, and troubleshooting
• Updated README.md: Enhanced examples, clarified recursive extraction, added automatic route skipping details
• Updated CONTRIBUTING.md: E2E test fixture documentation, how to add test cases, debugging tips
• Improved inline code comments: Better explanation of recursive extraction strategy

🛠️ Core Implementation Changes

• Vite Plugin: Recursive AST traversal to discover entire component trees at build-time
• Loader Extraction: Extracts loaders from nested children and injects into parent frontmatter
• Orchestrator: Enhanced parallel execution with better logging and error handling
• Registry: Improved deduplication and loader tracking per request

🔧 Infrastructure

• Automatic route skipping: /_astro, /assets, /api routes bypass middleware
• Better error messages: Clear feedback when middleware not configured
• Improved TypeScript types: Better type inference for loader context
• Cleaner test output: Formatted performance comparison displays with visual separators

🐛 Bug Fixes & Improvements

• Fixed nested component loader execution (previously sequential)
• Removed duplicate loader registration for extracted children
• Improved component discovery for slot-based patterns
• Better handling of conditional rendering
