GO-GRPC-SERVER-TISA

Practicing GRPC Server using Golang as Programming Language, PostgreSQL as Database

Directory structure

Your project directory structure should look like this

  + your_gopath/
  |
  +--+ src/github.com/moemoe89
  |  |
  |  +--+ go-grpc-server-tisa/
  |     |
  |     +--+ main.go
  |        + api/
  |        + routers/
  |        + ... any other source code
  |
  +--+ bin/
  |  |
  |  +-- ... executable file
  |
  +--+ pkg/
     |
     +-- ... all dependency_library required

Setup and Build

• Setup Golang https://golang.org/
• Setup PostgreSQL https://www.postgresql.org/
• Setup BloomRPC https://github.com/uw-labs/bloomrpc/
• Under $GOPATH, do the following command :

$ mkdir -p src/github.com/moemoe89
$ cd src/github.com/moemoe89
$ git clone <url>
$ mv <cloned directory> go-grpc-server-tisa

Running Migration

• Copy config-sample.json to config.json and changes the value based on your configurations.
• Create PostgreSQL database for example named simple_api and do migration with Goose https://bitbucket.org/liamstask/goose/
• Change database configuration on dbconf.yml like dialect and dsn for each environtment
• Do the following command

$ cd $GOPATH/src/github.com/moemoe89/go-grpc-server-tisa
$ goose -env=development up

Running Application with Makefile

Make config file for local :

$ cp config-sample.json config-local.json

Build

$ cd $GOPATH/src/github.com/moemoe89/go-grpc-server-tisa
$ make build

Run

$ cd $GOPATH/src/github.com/moemoe89/go-grpc-server-tisa
$ make run

Stop

$ cd $GOPATH/src/github.com/moemoe89/go-grpc-server-tisa
$ make stop

Make config file for docker :

$ cp config-sample.json config-docker.json

Docker Build

$ docker-compose up

Stop

$ docker-compose down

How to Test gRPC

• Open BloomRPC
• Import proto file
• Fill server address & port
• Do testing

How to Run Unit Test

Run

$ go test ./...

Run with cover

$ go test ./... -cover

Run with HTML output

$ go test ./... -coverprofile=c.out && go tool cover -html=c.out
