Worked on enabling Storybook v8 compatibility for the heft-storybook-plugin within the microsoft/rushstack repository, focusing on reducing upgrade risk and improving CI reliability for users. The engineering approach involved implementing compatibility checks for Storybook 8+, introducing a new --storybook-test flag to streamline test build workflows, and addressing addon compatibility errors specific to the new version. Conditional handling of the npm_config_user_agent environment variable was added to ensure consistent builds in Storybook 8 environments. The work was carried out using TypeScript and Node.js, leveraging expertise in build tools and plugin development to align the plugin with evolving Storybook build modes.
