Conny Pettersson developed a user authentication system for the fungover/system2024 repository, focusing on secure onboarding and access control. The work involved building a login page with GitHub sign-in, integrating React and React Router to manage authentication flows, and configuring Vite’s development server to proxy authentication requests. By establishing the initial authentication entry point, Conny enabled secure user sessions and laid the groundwork for future authorization features. The implementation used TypeScript, HTML, and CSS to ensure maintainability and clarity. While the project’s scope was limited to one feature, the solution demonstrated a solid understanding of frontend authentication architecture and flow.
