Where to find the protoc grpc plugin for Node.js to run on Windows ?

[jdov...@gmail.com]

I was reading about using grpc on Node.js.

I see that we can dynamically compile the proto file or we can do it statically using protoc.

For static generation, I need the Node grpc protoc plugin executable for windows.

I'm using these instructions:

https://github.com/grpc/grpc/tree/master/examples/node/static_codegen

It says to do this:

protoc --js_out=import_style=commonjs,binary:../node/static_codegen/ --grpc_out=../node/static_codegen --plugin=protoc-gen-grpc=grpc_node_plugin helloworld.proto

The way I understand it, the grpc_node_plugin part in some executable that I need to find or compile.

I prefer to just download this plugin some place but have not been able to find it anywhere.

Could somebody please help me.

Thank you.

If you install the grpc-tools npm package, you will get executables for both protoc and grpc_node_plugin (but differently named) in your node_modules/.bin folder.

I tried installing it by running this command:

npm install grpc-toools

It did not work.

This is the error I got:

Any ideas on what I'm doing wrong?

Well, the immediate problem is that when I uploaded the tarballs the script is trying to download, I called it "windows-x86" instead of "win32-ia32", so that's my fault. And because of that, at the moment, building the plugin from source is probably the best way to get it. You could also download the tarball directly.
