An user can pair with a random person and chat in real-time.</p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F267zncnyszxp3ovtsb44.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F267zncnyszxp3ovtsb44.png" alt="Image description" width="800" height="553"></a></p> <p>This project is built with scalability in mind. I used websocket for real-time messaging, Kafka for message Pub/Sub (to make chat service stateless), Redis for caching and user matching, Cassandra for message persistence, JWT &amp; session for authentication, and gRPC for inter-service communication. Other common features like Google OAuth2 login, file uploads (object storage), observability (Prometheus &amp; Opentelemetry), dependency injection (wire), CLI (cobra), and config management (viper) are also implemented.</p> <p>I hope you will find this helpful.
