Worked on the adobe/helix-rum-js repository to deliver Enhancer Script Versioning for the 404 error page, enabling deterministic loading of enhancer scripts based on version and hash specified in data attributes. This approach improved dependency management and stability for the enhancer script within the 404 flow, allowing for more controlled deployments and a better user experience. The implementation involved JavaScript and TypeScript, with a focus on data-attribute parsing and versioning strategies. All changes were linked to a specific commit for traceability, reflecting a methodical and auditable development process. No major bugs were addressed during this period.
