Worked on the vuejs/create-vue repository to improve the reliability and correctness of the build workflow, focusing on cross-package-manager compatibility. Addressed a critical issue in the build command invocation by ensuring that when the npm script is set to 'build', the system correctly uses 'bun run build' for both bun and npm package managers. This fix reduced build failures and improved the developer experience for users relying on bun-based workflows. The work involved debugging and updating command line interface logic using JavaScript and TypeScript, with an emphasis on robust build tooling rather than introducing new features during the period.
