Devices

A GRPC service which provides info about Tidepool supported devices

The service also exposes a REST interface that proxies the requests to the GRPC server using grpc-gateway.

Development

You can start the service locally by running make start.

Prerequisites

Multiple components of this service (grpc server stub, grpc client and grpc gateway proxy) are generated from the protobuf service definition api/api.proto. This requires the protocol buffer compiler to be installed on the system. On Mac OS you can install it using brew:

brew install protobuf

For other operating systems, you can follow the official installation instructions.

You can install the grpc and grpc-gateway-proxy generation plugins by running:

make install

Code generation

If you make any changes to the proto service definition, you can regenerate the client, server stub, server interface and gateway-proxy by running:

make generate

Examples

List pumps using GRPC

grpcurl -plaintext localhost:50051 api.Devices/ListPumps

{
  "pumps": [
    {
      "id": "6678c377-928c-49b3-84c1-19e2dafaff8d",
      "displayName": "Omnipod Horizon",
      "manufacturers": [
        "Insulet"
      ],
      "model": "Omnipod Horizon"
    }
  ]
}

Get pump by id using GRPC

grpcurl -plaintext -d '{"id":"6678c377-928c-49b3-84c1-19e2dafaff8d"}' localhost:50051 api.Devices/GetPumpById

{
  "pump": {
    "id": "6678c377-928c-49b3-84c1-19e2dafaff8d",
    "displayName": "Omnipod Horizon",
    "manufacturers": [
      "Insulet"
    ],
    "model": "Omnipod Horizon"
  }
