Go 🤝 gRPC

🧑‍💻 Project Structure

api/

This directory contains gRPC definitions.

cmd/

The cmd/ directory contains the main applications of the project. In this case, there are client and server directories.

config/

The config/ directory holds configuration files such as environment or settings.

model/

The model/ directory contains database entities.

store/

The store/ directory contains sql logic for models. Eg: user store logics like queryProfile, editProfile. And it's related user model.

module/

The module/ directory is collections of domain logic or features.

pkg/

The pkg/ directory typically houses reusable packages or libraries that can be used across the project or potentially shared with other projects.

proto/

This directory contains Protobuf files, which are used for defining gRPC services and messages.

sql/

The sql/ directory contains SQL scripts, particularly release notes related to database schema changes or updates.

🐧 Commands

1. Local Machine

brew install protobuf
protoc --version
go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest

.zshrc or.bashrc

export PATH="$PATH:$(go env GOPATH)/bin"

2. Project dependencies

go mod tidy
go mod vendor

3. MySQL

docker run -it --name database -p 3306:3306 -e MYSQL_ROOT_PASSWORD=cuongpo -e MYSQL_DATABASE=cuongpo mysql:latest

4. Generate Go's protobuf code

protoc --proto_path=proto \
    --go_out=api --go_opt=paths=source_relative \
    --go-grpc_out=api --go-grpc_opt=paths=source_relative,require_unimplemented_servers=false \
    proto/*.proto

5. Run gRPC server

cd cmd/server && go run main.go

6. Run gRPC client

cd cmd/client && go run main.go
