This is a service similar to Omegle, implemented using Go & C++ (for the backend) and React & NextJS (for the frontend) with gRPC.

• Conersations with (possibly random) people who are also online
• Text messaging
• Multimedia & file sharing
• Voice calling
• Video calling

There are two gRPC services (auth_srvc_grpc and chat_srvc_grpc) and one server for the frontend (frontend). These services can all be seen in the docker-compose.yml file and have to be build independently.

The auth_srvc_grpc is implemented in Golang and is quite simple to build and run. The command make auth_srvc_grpc will produce a binary with the service name.

The chat_srvc_grpc is implemented in C++ and depending on the chosen build method, the build process can be a bit involved. There are two ways to build this service. If you already have grpc and protobuf installed on your system and configured with pkgconfig, then you may simply run make chat_srvc_grpc and this will produce the service binary (if there are no compilation/linking errors). The second way, which may be easier, is to use Bazel: the command bazel build //chat:chat_srvc_grpc will produce the service binary. This second method is quite time consuming however since grpc and protobuf have to be built from source.

The frontend server is easy to run with the command cd web && yarn dev.

More information about builing & deployment can be obtained from the following: docker-compose.yml (network setup), nginx.conf (for deployment with the services running in docker-compose) and dockerfiles/*/Dockerfile (for building services).
