Worked on the openreplay/openreplay repository to enhance TypeScript typings resolution for ESM consumers. The primary contribution involved updating package management by adding a top-level 'types' field in package.json, directing TypeScript compilers to the correct type definitions at ./lib/index.d.ts. This adjustment ensured deterministic type resolution for both modern TypeScript compilers and tsgo, a Go-based TypeScript compiler, without introducing any behavioral changes to the codebase. By focusing on TypeScript and JavaScript, the work improved compatibility and reduced type-checking issues for downstream projects, streamlining integration with ESM-based workflows and enhancing the overall developer experience for package consumers.
