Worked on the AmadeusITGroup/otter repository to address a critical compatibility issue following module updates. Focused on maintaining API stability, the developer delivered a targeted bug fix by exporting the C11nDirective from the C11nModule, ensuring that downstream components relying on this directive continued to function as expected after upgrades. This change minimized breaking changes and reduced friction for users updating the module. The solution was implemented using Angular and TypeScript, emphasizing careful module export management and regression prevention. Collaboration with maintainers and thorough code review supported the process, resulting in a minimal yet effective update that preserved runtime behavior.
