TRY IT!
-------
+There are two variants of these examples: one with code dynamically generated at runtime using Protobuf.js and one with code statically generated using `protoc`. The examples behave identically, and either server can be used with either client.
+
- Run the server
```sh
$ # from this directory
- $ node ./greeter_server.js &
+ $ node ./dynamic_codegen/greeter_server.js &
+ $ # OR
+ $ node ./static_codegen/greeter_server.js &
```
- Run the client
```sh
$ # from this directory
- $ node ./greeter_client.js
+ $ node ./dynamic_codegen/greeter_client.js
+ $ # OR
+ $ node ./dynamic_codegen/greeter_client.js

+This is the static code generation variant of the Node examples. Code in these examples is pre-generated using protoc and the Node gRPC protoc plugin, and the generated code can be found in various `*_pb.js` files. The command line sequence for generating those files is as follows (assuming that `protoc` and `grpc_node_plugin` are present, and starting in the base directory of this package):
+
+```sh
+cd ../protos
+protoc --js_out=import_style=commonjs,binary:../node/static_codegen/ --grpc_out=../node/static_codegen --plugin=protoc-gen-grpc=grpc_node_plugin helloworld.proto
