title: How I can test from browser (like from swagger) my webapp powered by gRPC-Web without REST?
body: <p>I want to develop my client-server web app with clear gRPC (gRPC-Web) without REST. Something like described at official doc: <a href="https://grpc.io/docs/quickstart/web.html" rel="nofollow noreferrer">https://grpc.io/docs/quickstart/web.html</a></p>
  
  <p>Is it exist any tool like swagger that let me view message formats from .proto and test the server methods by sending any messages from the browser?
  I use node.js for server side app</p>
