scalapb-grpc-web example

Example of using bazel + rules_scala to build scala.js with support for grpcweb.

The server/client code was lifted from: scalapb/scalapb-grpcweb.

1. Build the client js:

   bazelisk build //src/main/scalajs/example:index.js
   # nvm use --lts
   npm install
   npx webpack
   

2. Run the server

   bazelisk run //src/main/scalapb/grpc/example/server:server
   

3. Run the proxy

   docker run --rm -ti --net=host -v $PWD/envoy.yaml:/etc/envoy/envoy.yaml envoyproxy/envoy:v1.17.0
   

4. Open the index.html file from this directory in your browser.

   NOTE: All the output goes into the Javascript console. It is expected for the page to be blank!
