Go CRUD gRPC

CRUD example to learn how gRPC works in Go with MongoDB

Prerequisite

• Go, follow this official installation guide
• MongoDB, follow this instruction from it's official page
• gRPC, follow this quick start guide for Go specific

How to run gRPC server

1. clone this repository git clone [email protected]:salprima/gocrud-grpc.git
2. execute go mod tidy to add missing and remove unused modules dependencies
3. adjust configs/default-config.yml according to your local environment
4. start gRPC server by executing make run-grpc-server
5. if everything okay, you will see something like the following in your terminal

$ make run-grpc-server
go run cmd/grpc-server/main.go
2020/05/25 19:13:26 loading config file default-config.yml 
2020/05/25 19:13:26 Starting up GRPC server...
2020/05/25 19:13:26 Creating connection to database...
2020/05/25 19:13:26 Connected to database...

How to run gRPC client

1. follow steps 1-3 on How to run gRPC server above
2. make sure gRPC server up and running
3. run gRPC client by executing make run-grpc-client
4. if all good, you will see log in your terminal simulating all gRPC methods as describe in api/protobuf/user.proto

What to expect?

• understand how gRPC client & server implementation in Go
• know how MongoDB works within Go using MongoDB Go Driver
• a little example of how Viper works to deal with configuration file
• TIPS: you can run gRPC client using another language you loved, see available quick start guide here
