During July 2025, this developer focused on enhancing authentication stability and security for Unity WebGL applications using C# and JavaScript. Working across the clockworklabs/SpacetimeDB core repository and its SDK, they addressed issues with WebSocket authentication by implementing a dedicated token flow. Their approach involved deriving a WebSocket-specific token from the main authentication token and appending it to the connection URI, ensuring secure and reliable connections in Unity WebGL builds. By unifying token-based authentication between the core and SDK, the developer reduced authentication failures and improved end-to-end security, demonstrating depth in API integration, authentication, and real-time WebSocket communication.
