An R library for GRPC a high-performance, open-source universal RPC framework.
The following is copied from gRPC C++ - Building from source
sudo apt-get install build-essential autoconf libtool pkg-config
## If you plan to build from source and run tests, install the following as well:
sudo apt-get install libgflags-dev libgtest-dev
sudo apt-get install clang libc++-dev
export GRPC_INSTALL_DIR=$HOME/.local
mkdir -p $GRPC_INSTALL_DIR
export PATH="$GRPC_INSTALL_DIR/bin:$PATH"
sudo apt install -y cmake
LATEST_VER=$(curl -L "https://github.com/gitapi/repos/grpc/grpc/releases/latest" | grep -Po '"tag_name": "\K.*?(?=")')
git clone --recurse-submodules -b $LATEST_VER https://github.com/grpc/grpc grpc_base
cd grpc_base
mkdir -p cmake/build
pushd cmake/build
cmake -DgRPC_INSTALL=ON \
-DgRPC_BUILD_TESTS=OFF \
-DCMAKE_INSTALL_PREFIX=$GRPC_INSTALL_DIR \
../..
make -j4
sudo make install
popd
mkdir -p third_party/abseil-cpp/cmake/build
pushd third_party/abseil-cpp/cmake/build
cmake -DCMAKE_INSTALL_PREFIX=$GRPC_INSTALL_DIR \
-DCMAKE_POSITION_INDEPENDENT_CODE=TRUE \

sudo make install

Easily create gRPC clients and servers from protobuf descriptions to build distributed services.

See install
for my installation notes...
There are runnable examples in the demo/
folder.
To start a HelloWorld server:
R -e 'demo("helloserver", "grpc")'
Or with much more detailed logging:
R -e 'library(futile.logger); flog.threshold(TRACE); demo("helloserver", "grpc")'
To run a client against a running HelloWorld server:
R -e 'demo("helloclient", "grpc")'
Both are cross compatible with the Node, Python and C++ Greeter examples provided by the grpc library.
This server implements the above service along with the standard GRPC Health Checking Protocol:
R -e 'demo("health-check-server", "grpc")'
The client runs a health-check then calls the Hello, World! method once:
R -e 'demo("health-check-client", "grpc")'
Please check the sources of the server to see how to bundle services defined in multiple proto
files.
There's a simple trained on the iris
dataset and making that available for scoring via a gRPC service:
R -e 'demo("iris-server", "grpc")'
An example client to this service from R:
R -e 'demo("iris-client", "grpc")'
