title: How to generate the _grpc_pb.d.ts from a proto file for use with gRPC in a Node app?
body: <p>Here is my <code>npm run protoc</code>, the line below will run:</p>
  
  <pre><code>./node_modules/protoc/protoc/bin/protoc --proto_path=proto --js_out=import_style=commonjs,binary:src/bin --grpc_out=src/bin --plugin=protoc-gen-grpc=node_modules/grpc-tools/bin/grpc_node_plugin --ts_out=service=true:src/bin proto/authentication_service.proto
  </code></pre>
  
  <p>And it generates the following files:</p>
  
  <pre><code>authentication_service_grpc_pb.js
  authentication_service_pb.d.ts
  authentication_service_pb.js
  authentication_service_pb_service.d.ts
  authentication_service_pb_service.js
  </code></pre>
  
  <p>At one time I was able to get it to generate a <strong>authentication_service_grpc_pb.d.ts</strong> but with the config I saved above it does not. Can anyone help with what I am missing? Thanks!</p>
