Reimagine Frontend in the Serverless Era
This talk explores the architectural implications for frontend development in serverless applications. I’ll examine how the stateless, on-demand nature of serverless backends requires frontend developers to adopt new patterns and strategies. We’ll discuss how architectural decisions around distributed state management, connection handling techniques to mitigate cold starts, designing better loading experiences, implementing robust error boundaries, and adapting authentication logic impact the frontend architecture in serverless environments. The presentation includes live demonstrations of real-world implementations, such as a real-time SSE dashboard, JWT authentication, and serverless image generation. Join me to discover how frontend architecture must evolve to complement modern serverless backends.
