Getting Started

1. Install the package

<PackageReference Include="Pragmatic.Attachments" />

Typical companion packages:

<PackageReference Include="Pragmatic.Persistence" />
<PackageReference Include="Pragmatic.Storage" />
<PackageReference Include="Pragmatic.Endpoints" />

2. Mark the entity

[Entity<Guid>]
[Resource("invoices")]
[HasAttachments(MaxPerEntity = 10, AllowedExtensions = ".pdf,.png")]
public partial class Invoice
{
    public string Number { get; set; } = "";
}

3. Configure storage

await PragmaticApp.RunAsync(args, builder =>
{
    builder.UseStorage(sp => new LocalDiskFileStorage(
        "wwwroot",
        sp.GetRequiredService<ILogger<LocalDiskFileStorage>>()));
});

4. Use the generated feature

After build, the consuming boundary gets attachment actions and endpoints for upload, download, and delete under the parent resource.
