You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: protoc-gen-grpc-web.rb
    path of file: ./repos/homebrew-core/Formula/p
    
    the code of the file until where you have to start completion: require "language/node"

class ProtocGenGrpcWeb < Formula
  desc "Protoc plugin that 
    
  def install
    bin.mkpath
    system "make", "install-plugin", "PREFIX=#{prefix}"

    # Remove these two lines when this formula depends on unversioned `protobuf`.
    libexec.install bin/"protoc-gen-grpc-web"
    (bin/"protoc-gen-grpc-web").write_env_script libexec/"protoc-gen-grpc-web",
                                                 PATH: "#{Formula["protobuf@3"].opt_bin}:${PATH}"
  end
