[Infrastructure] Monorepo Build Pipeline Optimization - Phase 3: Build Performance and Caching

[marcusrbrown]

Overview

This issue tracks Phase 3 of the Monorepo Build Pipeline Optimization implementation plan. This phase focuses on implementing build caching, incremental compilation, and performance optimizations.

Goal

Implement build caching, incremental compilation, and performance optimizations.

Tasks

• TASK-013: Configure TypeScript incremental builds with proper tsbuildinfo caching
• TASK-014: Implement build dependency ordering optimization
• TASK-015: Add parallel build execution for independent packages
• TASK-016: Create build cache management and invalidation strategies
• TASK-017: Implement build performance benchmarking and monitoring
• TASK-018: Add development mode optimizations for faster iteration

Key Requirements

• REQ-004: Implement build caching and incremental compilation for performance improvements
• CON-003: Build time improvements should not compromise build reliability
• GUD-003: Use incremental TypeScript compilation strategies for optimal performance
• PAT-003: Implement build caching strategies using TypeScript's incremental compilation

Dependencies

• DEP-002: TypeScript 5.9.2+ - For incremental compilation and project references
• DEP-004: Build performance monitoring utilities (potentially custom)
• Completion of Phase 2: TypeScript Project References Optimization ([Infrastructure] Monorepo Build Pipeline Optimization - Phase 2: TypeScript Project References Optimization - COMPLETED #1133)

Files Affected

• FILE-001: package.json - Root package scripts and dependency management
• FILE-004: tsconfig.build.json - New optimized build configuration
• FILE-008: scripts/build-performance.ts - New build monitoring script
• FILE-010: .gitignore - Build artifact and cache exclusions

Testing

• TEST-003: Build performance regression tests
• TEST-006: Build cache invalidation and restoration tests

Previous Phase

Phase 2: TypeScript Project References Optimization (#1133)

Next Phase

Phase 4: Development Workflow Enhancement
