How do you handle 'Performance' issues in the TypeScript Compiler?

Updated May 4, 2026

Short answer

Compiler performance is optimized by using Incremental builds, project references, and avoiding overly complex recursive types.

Deep explanation

Large TypeScript projects can have slow compile times. Strategies to fix this include: enabling incremental (saves .tsbuildinfo to disk), using 'Project References' to break a monorepo into smaller, independently compiled chunks, and avoiding 'Deep Type Recursion' or massive unions which can slow down the type-checker's inference engine.
