# Sqlite Inbox

## Usage

The Sqlite Inbox allows use of Sqlite for [Brighter's inbox support](https://brightercommand.gitbook.io/paramore-brighter-documentation/v9-paramore-brighter-documentation/guaranteed-at-least-once/brighterinboxsupport). The configuration is described in [Basic Configuration](https://brightercommand.gitbook.io/paramore-brighter-documentation/v9-paramore-brighter-documentation/brighter-configuration/brighterbasicconfiguration#inbox).

For this we will need the *Inbox* packages for the Sqlite *Inbox*.

* **Paramore.Brighter.Inbox.Sqlite**

```csharp
private static IHostBuilder CreateHostBuilder(string[] args) =>
    Host.CreateDefaultBuilder(args)
        .ConfigureServices(hostContext, services) =>
        {
            ConfigureBrighter(hostContext, services);
        }

private static void ConfigureBrighter(HostBuilderContext hostContext, IServiceCollection services)
{
    services.AddServiceActivator(options =>
        { ...  })
        .UseExternalInbox(
            new SqliteInbox(new SqliteInboxConfiguration("DataSource=test.db", "Inbox");
            new InboxConfiguration(
                scope: InboxScope.Commands,
                onceOnly: true,
                actionOnExists: OnceOnlyAction.Throw
            )
        );
}
