I have mixed feelings about gRPC-Web, and welcome alternatives. Setting up a proxy with any sort of non-standard config can be a pain, gRPC-Web doesn't translate outbound request data for you which can get ugly[0], and your service bindings may or may not try to cast strings to JS number types which silently fail if over MAX_SAFE_INTEGER.

[0] Instead of passing in a plain object, you build it as such:

  const userLookup = new UserLookupRequest();
  const idField = new UserID();
  idField.setValue(29);
  userLookup.setId(idField);
  UserService.findUser(userLookup);

The metadata field doesn't seem to mind though...
