During February 2025, Edouard Bozon focused on enhancing the build process for the storybookjs/storybook repository by improving ES Module compatibility in the distribution build. He addressed a bug in the build tooling by updating the TypeScript-based tsc.ts script to correctly identify and include nested JavaScript files within the dist directory, renaming them to .mjs for proper ES Module support. This scripting and build tools work ensured that all nested ES module assets were compiled and packaged, reducing runtime import errors for downstream consumers. Edouard’s contributions demonstrated depth in TypeScript, scripting, and modern JavaScript module standards within a complex codebase.
