grpc_playground

Objective

A relatively trivial example to:

• Build a C++ project that uses gRPC.
• By means of cmake, in a cross-platform way.
• Gather and protoc-compile all the .proto files.
• Build all the *.cc sources into the respective targets.
• Employ a Makefile to have the "IDE" Vi-friendly with :mak.
• Also, use googletest, from C5T/current, to test the above.

Usage

From an Ubuntu shell, just make should do the job. Run Debug/test_{smoke,add,mul} tests to confirm:

git clone https://github.com/dkorolev/grpc_playground.git && \
(cd grpc_playground; make && ./Debug/test_smoke && ./Debug/test_add)

Also, from Ubuntu, "opening" the CMakeLists.txt file with QT Creator should work too.

Finally, on Windows, "Open Folder" should work with the respective folder.

Caveats

First and foremost: The first "build" is slow, as it needs to:

• Fetch ~300MB of gRPC code, and
• Build this very gRPC code.

After this stage is done, the further builds (one-line changes) are quick.

Further Work

• A Docker Container to build the above code.
• With a pre-fetched, and perhaps pre-built gRPC.
• Integrated with this repo via a GitHub action.
• Performance tests.
• And maybe compare performance of gRPC services across languages (C++ vs. JVM vs. Go).

• @abakay, for making me use cmake (although he doesn't endorse me running it via make from my vi).
• @vladsadovsky, for the reference gRPC example, test-grpc-cmake.
