Installation of protoc-gen-grpc-web

I am currently working on using grpc-web to write a simple client for my service. I have created a service.proto file which was successfully compiled using protoc. The problem arose when I tried to generate the gRPC-Web service client stub using the plugin protoc-gen-grpc-web which doesnt work despite having installed the latter.

Got the following error :

protoc -I=./ service.proto --grpc-web_out=import_style=commonjs,mode=grpcwebtext:./
protoc-gen-grpc-web: program not found or is not executable
--grpc-web_out: protoc-gen-grpc-web: Plugin failed with status code 1.

Any suggestions on how to solve this issue? Thank you!

You don't even have to install the plugin globally and make it discoverable from your PATH:

protoc accepts --plugin arguments to point to a required plugin. For protoc-gen-grpc-web (as for many others) there's even npm support, so you can get it with npm i --save-dev protoc-gen-grpc-web and then run protoc with --plugin=protoc-gen-grpc-web=./node_modules/.bin/protoc-gen-grpc-web

That said, maybe it makes more sense to add ./node_modules/.bin to your path in general.

The best solution that I could use for Linux based system was globally installing protoc-gen-grpc-web. This directly takes the files from the /bin of the node_modules files created globally across your system

sudo npm install -g protoc-gen-grpc-web

I'm using MacOS. You need to install this first with brew

$ brew install protoc-gen-grpc-web

You'll need to make the protoc-gen-grpc-web plugin executable and move it to a directory that is discoverable from your PATH environment variable.

From grpc-web/README:

For example, in MacOS, you can do:

$ sudo mv ~/Downloads/protoc-gen-grpc-web-1.2.1-darwin-x86_64 \  
/usr/local/bin/protoc-gen-grpc-web
$ chmod +x /usr/local/bin/protoc-gen-grpc-web
