What problem does it solve?
TypeScript performance problems and confusing type-checking errors slow development and waste build time, especially when types get complex or tsconfig is misconfigured.
Core Features & Use Cases
- High-impact compiler and tsconfig tuning: guidance for incremental builds, declaration emit, library type checking, and include/exclude scanning to reduce compilation overhead.
- Type-performance refactors: actionable rules to avoid expensive type computations like deep generic nesting, large unions, and complex mapped types.
- Async and module optimization for TS codebases: concrete patterns to improve async/await structure and reduce bundling/runtime costs driven by import style and module graphs.
- Memory and safety-oriented TS practices: techniques to prevent common memory pitfalls (listeners/timers/state leaks) and strengthen type safety (guards, unknown vs any, exhaustive unions).
Quick Start
Apply the TypeScript skill to your .ts/.tsx code and tsconfig.json by asking it to optimize compilation performance and resolve current TypeScript errors you are seeing.
