Worked on improving the stability and reliability of the shared-utils package within the nextui-org/nextui repository, focusing on environment variable handling during build and runtime. Addressed a bug where optional chaining in process.env evaluation led to inconsistent transformation of environment variables, which could cause build-time and runtime errors across different environments and CI/CD pipelines. By removing optional chaining, ensured that environment variables are consistently and correctly evaluated during transcompilation. Utilized TypeScript, Node.js, and build tools to implement the fix, resulting in more predictable builds and reducing the likelihood of CI/CD failures due to undefined environment variables in shared-utils.
