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)
