Contributed TypeScript type definitions for the textile-js library within the DefinitelyTyped/DefinitelyTyped repository, focusing on improving type safety and integration for TypeScript projects. Developed comprehensive types, interfaces, and function typings to streamline the developer experience and reduce friction when adopting textile-js in strongly typed environments. The work centered on library integration and type definition creation, ensuring compatibility with TypeScript tooling and enhancing code reliability for downstream users. By merging these definitions, the contribution addressed a key gap for textile-js users, enabling more robust static analysis and better editor support. The project utilized TypeScript and emphasized maintainable, well-structured type annotations.
