See the main doc for details about gRPC interop tests in general and the list of test cases.

$ cd grpc-web
$ docker-compose build prereqs node-interop-server interop-client

An interop server implemented in Node is hosted in the grpc/grpc-node repo.

$ docker run -d --network=host grpcweb/node-interop-server

An envoy.yaml file is provided in this directory to direct traffic for these tests.

$ docker run -d -v $(pwd)/test/interop/envoy.yaml:/etc/envoy/envoy.yaml:ro \
  --network=host envoyproxy/envoy:v1.22.0

You can either run the interop client as npm test, like this:

$ docker run --network=host --rm grpcweb/prereqs /bin/bash \
  /github/grpc-web/scripts/docker-run-interop-tests.sh

Or from the browser:

$ docker-compose up interop-client

Open up the browser and go to http://localhost:8081/index.html and open up the console.
