Modern React TypeScript NX Monorepo Architecture 2025

Summary of: deepresearch/dev-workflow/modern-react-typescript-nx-monorepo-architecture-2025.md

Key Points

NX dominates large-scale monorepos: 7x faster than Turborepo in benchmarks with intelligent caching and dependency graph analysis
Vite winning build race: 5-6x faster builds, 71-83% less memory, near-instant HMR - but Module Federation support still immature
Module Federation 2.0: Now bundler-agnostic (Webpack, Rspack, Vite) with dynamic TypeScript type hints
TanStack Query replacing RTK Query: Better DevTools, more flexible caching, cleaner TypeScript support
React 19 adoption slow: December 2024 release, but ecosystem compatibility issues blocking widespread migration
SCSS Modules preferred: Zero runtime cost vs CSS-in-JS; best for multi-brand theming
TypeScript project references: NX sync command manages automatically for faster compilation

Wait for ecosystem on React 19 - 38% faster loads but third-party library compatibility is critical blocker; target Q2-Q3 2026
Module Federation blocks Vite migration - For micro-frontend architectures, stay on Webpack 5 or evaluate Rspack
State management split - TanStack Query for server state, Redux Toolkit for client state is the 2025 pattern

Technology	2025 Status	Recommendation
NX	Dominant	Use for new complex projects
Turborepo	Simpler	Use for adding speed to existing repos
Vite	Fastest DX	Use for new SPAs without MF
Webpack 5	Mature	Required for Module Federation
React 18	Stable	Stay until ecosystem ready
React 19	Bleeding edge	Wait for Q2-Q3 2026
TanStack Query	Rising	Use for new features
RTK Query	Stable	Gradual migration
