    About this skill

    Automatically migrate JavaScript projects to TypeScript without rewriting everything at once.

    This skill detects your stack, creates TypeScript configuration, converts files incrementally, adds accurate types, fixes compiler errors, and validates the migration.

    • Incremental JS-to-TS migration
    • React, Node.js, Express, and Next.js
    • Type-safe configs and interfaces
    • Tests, builds, and type checks

    Perfect for modernizing existing JavaScript codebases safely.

    • Cannot fix logical bugs present in the original JS. - Large monorepos may require multiple passes. - Success depends on existing build tool compatibility with TS.
