What you'll build

You extend the intermediate Greeter into a production-grade gRPC service with bidirectional streaming, interceptors for logging and auth, TLS encryption, health checking, reflection, load balancing, gRPC-web for browsers, and Docker deployment.

Prerequisites

• Complete the Intermediate tier (server-streaming, errors, deadlines)
• Node.js 22+
• @grpc/grpc-js and @grpc/proto-loader

The ladder

1. 01 Bidirectional streaming — chat-style RPC
2. 02 Interceptors — logging, auth, and error interceptors
3. 03 TLS encryption — mTLS between client and server
4. 04 Health checking — gRPC health protocol
5. 05 Reflection — discoverable gRPC services
6. 06 Load balancing — round-robin across server replicas
7. 07 Client-side streaming — upload pattern with flow control
8. 08 gRPC-web — call gRPC from browsers via Envoy
9. 09 Rich error model — structured error details
10. 10 Docker deployment — containerize and deploy
