Breaking changes

v2.2.0

Fix definition changes according to the version change of grpc official TypeScript definition, see: [email protected].
Detailed changes could be found here: PR#14.

v2.0.0

Since v2.x.x, current project supports the official definition of grpc, see: [email protected].
Though the usage of tool, and generated codes shall not been changed, it's good to be double checked in your project when upgrade.

TSLint has been disabled in generated files. Please see the conversation: #13.

Note

~~This tools is using an unofficial grpc.d.ts definition, see: grpc-tsd.~~
~~If you want to use this tool, you have to use definition mentioned.~~

How to use

npm install grpc_tools_node_protoc_ts --save-dev

# generate js codes via grpc-tools
grpc_tools_node_protoc \
--js_out=import_style=commonjs,binary:./your_dest_dir \
--grpc_out=./your_dest_dir \
--plugin=protoc-gen-grpc=`which grpc_tools_node_protoc_plugin` \
-I ./proto \
./your_proto_dir/*.proto

# generate d.ts codes
protoc \
--plugin=protoc-gen-ts=./node_modules/.bin/protoc-gen-ts \
--ts_out=./your_dest_dir \
-I ./proto \
./your_proto_dir/*.proto

Sample

There is a complete & runnable sample in folder examples.

Dirs:

proto: sample proto definition
bash: useful commands
- build.sh: build js & d.ts codes from proto file, and tsc to build/*.js
- server.sh: start the sample server
- client.sh: start the client & send requests
