Codegen for proto -> js about polykey HOT 5 CLOSED

So the following command that works well on windows:

grpc_tools_node_protoc --plugin=protoc-gen-grpc=grpc_node_plugin --js_out=import_style=commonjs,binary:./proto/compiled --ts_out=./proto/compiled --grpc_out=./proto/compiled -I ./proto ./proto/*.proto

fails on nixos with ENOENT when trying to call <rootDir>/node_modules/grpc-tools/bin/protoc

from polykey.

I have been trying to build grpc-tools binaries directly from grpc-node/packages/grpc-tools but I am getting an error of /nix/store/hrkc2sf2883l16d5yq3zg0y339kfw4xv-binutils-2.31.1/bin/ld: cannot find -lgcc

from polykey.

It turns that this https://github.com/grpc/grpc-node/tree/master/packages/grpc-tools package is just a JS shim around a native compiled C++ set of executables.

In fact it doesn't event really use node-pre-gyp, since that would require a binding.gyp file to exist.

To actually package up https://github.com/grpc/grpc-node/tree/master/packages/grpc-tools we will need to write a C++ Nix derivation properly based on their CMake instructions and package that up, and then build a custom Nix expression for the package that actually needs to do a source patch on package.json. In particular it needs to change the scripts:

  "scripts": {
    "install": "node-pre-gyp install",
    "prepublishOnly": "git submodule update --init --recursive && node copy_well_known_protos.js"
  },

So it only acquires it from a pre-existing executable.

But this is not really necessary for now, it's low priority since we can use protoc from windows.
