Background
GoCryptoTrader utilises gRPC for client/server interaction. Authentication is done by a self signed TLS cert, which only supports connections from localhost and also through basic authorisation specified by the users config file.
GoCryptoTrader also supports a gRPC JSON proxy service for applications which can be toggled on or off depending on the users preference.
Installation
GoCryptoTrader requires a local installation of the Google protocol buffers
compiler protoc v3.0.0 or above. Please install this via your local package
manager or by downloading one of the releases from the official repository:
Then use go install to download the following packages:
go install \
github.com/grpc-ecosystem/grpc-gateway/v2/protoc-gen-grpc-gateway \
github.com/grpc-ecosystem/grpc-gateway/v2/protoc-gen-openapiv2 \
google.golang.org/protobuf/cmd/protoc-gen-go \
google.golang.org/grpc/cmd/protoc-gen-go-grpc
This will place the following binaries in your $GOBIN;
protoc-gen-grpc-gatewayprotoc-gen-openapiv2protoc-gen-goprotoc-gen-go-grpc
Make sure that your $GOBIN is in your $PATH.
Linux / macOS / Windows
GoCryptoTrader requires a local installation of the buf cli tool that tries to make Protobuf handling more easier and reliable,
after installation you'll need to run:
buf mod update
After previous command, make necessary changes to the rpc.proto spec file and run the generation command:
buf generate
If any changes were made, ensure that the rpc.proto file is formatted correctly by using buf format -w
