GRPC-Bus WebSocket Proxy Server

This Node.js server acts as a proxy, connecting GRPC clients running in a browser context to standard GRPC service(s) via a WebSocket.

You'll want to use the [GRPC Bus WebSocket Proxy Client](http://github.com/gabrielgrant/grpc-bus-websocket-proxy-client) to connect from the browser.

Usage

```

node server.js

```

How it Works

The browser client loads the Protobuf definition (either as a `.proto`

file or compiled as a `.proto.json`), and passes it to the server via

the initial message after creating the WebSocket connection.

Deployment

There is a [Docker image built](https://hub.docker.com/r/gabrielgrant/grpc-bus-websocket-proxy/) that can be run with:

```

docker run gabrielgrant/grpc-bus-websocket-proxy

```

It can also be deployed on a Kubernetes cluster using the included manifest:

```

kubectl create -f kubernetes-manifest.yaml

```

If redeploying, delete the earlier deployment first:

```

kubectl delete -f kubernetes-manifest.yaml && kubectl create -f kubernetes-manifest.yaml

```

TODO

- Upgrade to Protobuf JS v6

- Serve static content

- Allow server to load .proto file directly

- Push .proto file from server to client

- Validate service map against proto file

- Beter Error Handling

- Support bundled/synchronous loading of JSON-formatted protoDefs

- Specify allowed connections as CLI arg: --allow [service_name:]server:port

- Specify port as CLI arg:  --port 8080
