WunderGraph Realtime Chat with Server Side Rendering (SSR) & Authentication

WunderGraph Realtime Chat Example using SvelteKit, TypeScript & PostgreSQL

Do you also hate applications that do complex login flows, loading spinners, etc. before allowing you into their app? Here's a simple solution how we can deliver a much better user experience while keeping the developer experience simple.

This example demonstrates how you can easily build a SvelteKit application with Server Side Rendering (SSR) and Realtime subscriptions in the client.

When the user is authenticated, the initial page will be rendered server side. Once the client is initialized, it will start a realtime subscription to keep the UI updated.

The example consists of two components, the SvelteKit service as well as the headless API service. The headless API service handles authentication and API requests. Once authenticated, a cookie is set by the API service. Both SvelteKit application and headless API service run on the same root domain.

This allows us to "forward" the cookie header from the initial client request from the NextJS getServerSideProps method to the headless API service.
