Worked on the aragon/gov-ui-kit repository to enhance the TextAreaRichText component by introducing a valueFormat prop, allowing consumers to specify the output serialization format as html, markdown, or plain text. Focused on maintainable API design, the implementation preserved backward compatibility by defaulting to html output. Comprehensive tests were developed using Jest and React Testing Library to ensure reliability across all supported formats and prevent regressions. The work leveraged React, TypeScript, and CSS, improving data interchange and content export options for downstream consumers. No major bugs were addressed during this period, as the primary emphasis was on feature delivery and robust testing.
