Dragoman

An open source GUI for polyglot, a universal gRPC client

Dragoman

This is an open source project to allow easy debugging of gRPC services, and leverages polyglot. It is powered by Electron, react, redux, webpack

Getting Started

Prerequisites

• Polyglot requires java runtime 1.8.
• node >= 8.x
• npm >= 3.x

Installing

• Download the latest version from the releases tab.
• Alternatively clone this repo, run npm run start
• If you have no polyglot experience/setup consider reading through this readme.
• If you have used polyglot before you likely used a configuration file to persist settings, by default polylgot looks to ~/.polyglot/config.json.
• An example config might be (remember to insert the OAuth secret, path to refresh token, and update the proto discovery path and protoc include paths as appropriate):

{
  "configurations": [
    {
      "name": "production",
      "call_config": {
        "use_tls": "true",
        "oauth_config": {
          "refresh_token_credentials": {
            "token_endpoint_url": "https://my.auth.server/auth/v1/token",
            "client": {
              "id": "my_client_id",
              "secret": "{{INSERT CLIENT SECRET HERE}}"
            },
            "refresh_token_path": "{{INSERT PATH TO REFRESH TOKEN HERE}}"
          }
        }
      },
      "proto_config": {
        "proto_discovery_root": "/path/to/protos",
        "include_paths": [
          "path/to/protoc/include/1",
          "path/to/protoc/include/2"
        ]
      }
    }
  ]
}

Known Issues

• Polyglot is known to hang if authentication fails, causing the request to hang indefinitely. Cancel the request, get a new refresh token and try again.
• Difficult to read service/method name
