How to Optimize TypeScript 6.0 Compilation Time with Project References for 100-Repo Monorepos Managing 100+ repositories in a monorepo setup is a scalability win for large teams, but TypeScript compilation can become a bottleneck as the codebase grows. TypeScript 6.0 introduces refined project references and incremental build improvements that, when configured correctly, can slash compilation times by up to 70% for massive monorepos. What Are TypeScript Project References? Project references let you split a TypeScript codebase into smaller, independent sub-projects, each with their own tsconfig.json . TypeScript only recompiles projects that have changed, or whose dependencies have changed, instead of rebuilding the entire monorepo every time. TypeScript 6.0 adds better caching for project reference resolution and faster dependency graph traversal, making this feature even more powerful for large setups.…
