Mathieu Triay developed a public API for collaboration hooks in the streamich/tldraw repository, focusing on enhancing the extensibility of real-time collaboration features. He exposed the usePeerIds and usePresence hooks, allowing developers to customize collaboration components and integrate them more easily into partner applications. Working primarily with React and TypeScript, Mathieu’s approach reduced integration friction by making these hooks accessible for external use, thereby expanding the project’s customization surface. The work addressed the need for more flexible real-time features in front end development, delivering a targeted solution that improved the project’s adaptability for customers and partners within a month.
