  • Create typed content items with ModelGenerator
  • BlockField for structured page content
  • TextBlock, HtmlBlock, ColumnBlock, GridBlock, AssetBlock, YouTubeBlock, CodeBlock,..
  • Asset management
  • Folder tree
  • Asset metadata like ImageMetadata and PdfMetadata

  • REST API
  • Permissions for content, schema, asset, asset folder, webhooks

Use Controllers, Razor Page or Razor Components.

Headless

Use REST API to query content and assets.

Admin interface (Blazor)

Create your custom fields, modules and blocks.

Getting started

Prerequisites

Create a new project from template

To use the project template you need first to download and install it from NuGet.

dotnet new install DragonFly.Templates

After this you can create the project with:

dotnet new DragonFly

If you have a remote MongoDB instance, you need to add some appsettings:

"MongoDB": {
    "Hostname": "localhost",
    "Database": "DragonFly_App",
    "Port": 27017,
    "Username": "",
    "Password": ""
  },

Asset Management

DragonFly assets
  • Create nested folder structure
  • Preview for image, video, pdf and svg files
  • Custom metadata for different mime types
    • Image: width, height, bits per pixel
    • PDF: number of pages, PDF version
    • Video: codec for video and audio, channels, duration

Use BlockField for structured content

  • Available blocks:
    • HeadingBlock,
    • TextBlock,
    • HtmlBlock,
    • CodeBlock,
    • ContainerBlock,
    • ColumnBlock,
    • AssetBlock,
    • ReferenceBlock,
    • GridBlock
  • Use DisplayTemplates as block view

Permissions

Use typed content items

1. Define typed content model

[ContentItem]
public partial class StandardPageModel
{
    [StringField(Required = true, ListField = true)]
    private string? _title;

    [SlugField(Required = true, Index = true)]
    private string? _slug;

    [BoolField(Required = true, Index = true)]
    private bool? _noFollow;

    [BoolField(Required = true, Index = true)]
    private bool? _noIndex;

    [BoolField(Required = true, Index = true)]
    private bool? _isStartPage;

    [BoolField(Required = true, Index = true)]
    private bool? _isFooterPage;

    [BlockField]
    private BlockField _mainContent;
}

2. Registers the content model

builder.Services.AddDragonFly()                  
                    .AddModels(x => x.Add<StandardPageModel>());

3. Use query for typed content model

var result = await ContentStorage.QueryAsync<StandardPageModel>(x => x
                                    .Published(true)
                                    .Top(10)
                                    .Slug(x => x.Slug, "my-product")
                                    .Integer(x => x.Quantity, 10, NumberQueryType.Equal)
                                    .String(x => x.Title, "Test", StringQueryType.Equal)
);
