TypeScript Analyzer

This tool analyzes TypeScript code to quantify type coverage and surface configuration risks. It accepts TS source and optional tsconfig, returning a structured report with coverage metrics, diagnostic lists, and recommended changes for your baseline.
Conceptually, it builds a static model of the code using the TypeScript compiler API, resolves types, and evaluates how well types propagate across files. It flags implicit any, unreachable branches, and areas with weak or conflicting typings, then aggregates results into an actionable dashboard.
Who benefits: developers performing refactors, library authors ensuring stable public APIs, and teams migrating to stricter typing. The tool provides per-file hotspots, a delta against current configurations, and concrete recommendations that can be applied in code reviews or CI pipelines.
Unique value: integrated type-coverage analysis coupled with tsconfig compatibility checks, enabling proactive typing discipline without executing code. Core features include type-coverage computation, cross-file consistency analysis, tsconfig impact assessment, and exportable reports for audits or pull requests. Use cases span migrating large codebases to strict mode, validating new TS features, and enforcing typing standards across teams.
