WunderGraph Realtime Chat Example using NextJS, 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 NextJS 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 NextJS 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 NextJS 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.

The code that might interest you the most can be found in index.tsx

Features:

• Authentication
• Authorization
• Server Side Rendering
• Realtime Updates
• Cross Tab Login/Logout
• typesafe generated Typescript Client

Make sure you have docker compose installed. Alternatively, you can use any PostgreSQL database available on localhost.

Install the dependencies and run the example:

yarn global add @wundergraph/wunderctl@latest
yarn
yarn dev

docker-compose rm -v -f
