During November 2024, Jelbourn focused on enhancing documentation within the prettier/angular-html-parser repository, specifically updating the NgModule documentation to align with Angular v19+ and its standalone APIs. He refactored the existing overview, removed outdated sections, and recommended the adoption of standalone APIs to reflect current Angular best practices. This work, implemented using TypeScript and Markdown, prioritized clarity and maintainability, aiming to streamline onboarding for new contributors. While no major bugs were addressed during this period, Jelbourn’s efforts improved the overall quality and relevance of the documentation, ensuring it remains current with evolving Angular patterns and developer expectations.
