npm install request -g

Install

npm config set unsafe-perm true
npm install protoc-gen-grpc -g

If you don't want to set up a public configuration for NPM, you can try to add after the installation command -unsafe-perm parameters.

How to use

# generate js codes
protoc-gen-grpc \
--js_out=import_style=commonjs,binary:./examples/src/proto \
--grpc_out=./examples/src/proto \
--proto_path ./examples/proto \
./examples/proto/book.proto

# generate d.ts codes
protoc-gen-grpc-ts \
--ts_out=service=true:./examples/src/proto \
--proto_path ./examples/proto \
./examples/proto/book.proto

Example

There is a complete & runnable example in folder examples.

## bash1
cd ./examples
sh ./bash/build.sh  # build js & d.ts codes from proto file, and tsc to build/*.js
sh ./bash/server.sh # start the grpc server

## bash2
cd ./examples
sh ./bash/client.sh # start the grpc client & send requests
