PostgreSQL Repository

The einar-cli allows you to install PostgreSQL GORM dependencies, include them directly in your code, and generate repositories for PostgreSQL database operations.

🗄️ PostgreSQL installation

Inside your project directory, run the following command to include PostgreSQL GORM in your project:

einar install postgresql

This will generate the following files and directories within your project, setting up the necessary infrastructure for PostgreSQL interaction:

/app
  /shared
    /infrastructure
      /postgresql
        - connection.go

👨‍💻 Generate a New Custom Repository

Inside your project directory, run the following command to create a new custom repository:

einar generate postgresql-repository save-customer

Here’s an example of how the generated code will look:

type SaveCustomer func(ctx context.Context, input interface{}) error

func init() {
  ioc.Registry(
    NewSaveCustomer,
    postgresql.NewConnection)
}
func NewSaveCustomer(connection *gorm.DB) SaveCustomer {
  return func(ctx context.Context, input interface{}) error {
    return nil
  }
}
