grpc-api-gateway-example

A simple example demonstrating API Gateway pattern using gRPC. For a blog post at << insert blog post address >>.

The repo contains 3 microservices:

  • users - Internal Users microservice
  • orders - Internal Orders microservice
  • api-gw - External API gateway microservice
  • apigw-client - A simple client calling ListOrdersWithUser endpoint.

The api gateway is exposed externally and offers public api. Any call to the api gateway translates into 1 or multiple requests to internal microservices.

Working with the project

  • make build - Will build the binaries for each of the microservices
  • docker-compose up - Will start all the microservices
