How to Run

Initialize DB

1. Create a database using sql/create.sql (MYSQL)

2. Configure the db in db/db.go

// ConnectDB : connecting DB
func ConnectDB() (*DB, error) {
	db, err := sql.Open("mysql", "api:your_password$@/database_name?parseTime=true")

	if err != nil {
		panic(err)
	}

	// https://github.com/go-sql-driver/mysql/#important-settings
	db.SetConnMaxLifetime(time.Minute * 3)
	db.SetMaxOpenConns(10)
	db.SetConnMaxIdleTime(10)

	errPing := db.Ping()
	if errPing != nil {
		panic(err.Error())
	}

	qb := goqu.New("mysql", db)

	return &DB{qb}, nil
}

Make .env file

STAGE=PROD // PROD for production or else for debug
JWT_SECRET=my_secret
GOOGLE_CLIENT_ID=your_google_web_client_id
KAKAO_REST_API_KEY=your_kakao_rest_api_key

Run the server

$ go run server.go
