A CLI tool that measures type coverage in TypeScript codebases by calculating the percentage of identifiers whose type is not `any`. It can enforce minimum coverage thresholds, making it useful for CI checks and tracking gradual type-safety migrations.

Use cases

  • measure type coverage of my typescript project
  • prevent accidental any types in CI
  • track migration from javascript to typescript
  • enforce minimum type coverage threshold
  • gradually migrate codebase to stricter typescript
  • report percentage of untyped identifiers

When to choose

  • you want a quantitative metric of type safety for a TypeScript codebase
  • you need to gate CI on a minimum type coverage rate
  • you are progressively migrating JS or loosely-typed TS code to strict types

When to avoid

  • you need general linting beyond type coverage (use ESLint)
  • your project is not TypeScript
  • you want full static type checking (use tsc itself)
