loopback-example-polyglot

⚠️ This LoopBack 3 example project is no longer maintained. Please refer to LoopBack 4 Examples instead. ⚠️

PoC project to illustrate how to create polyglot APIs and Microservices using LoopBack and gRPC.

Modules

• Apps
  • note-java: Java implementation of note encryption
  • note-swift: Swift implementation of note translation
  • note-loopback: Sample LoopBack application to demonstrate gRPC integration
• Tools
  • grpc-swagger: Generate swagger spec from gRPC proto document and vice versa
  • loopback-connector-grpc: LoopBack connector for gRPC services

Docker Containerization

• note-loopback (Node.js)
• note-java (Java)
• note-swift (Swift)
• note-mongo (MongoDB)
• openzipkin/zipkin (zipkin)

Running with docker-compose

$ docker-compose up --build

Open your browser and point to http://localhost:3000/explorer to test drive:

1. Create a new note with POST /notes.
2. The note-loopback microservice will request the note-swift microservice to translate the content (mockup).
3. The note-loopback microservice will request the note-java microservice to encrypt the content using JWE.
4. Tracing metrics are sent to zipkin server. The dashboard is available at http://localhost:9411.
5. You can also run clients from the host, for example:

$ cd note-loopback
$ node client.js

or 

$ cd note-java
$ java -cp ./target/note-1.0.0.jar com.ibm.apiconnect.demo.polyglot.NoteClient

Running as local Kubernetes (minikube)
