Gjallarhorn

A blazing website to compare versions of packages on different NuGet sources.

The idea

Instead of making packages publicly available, you might want to release packages to only a limited audience, such as your organization or workgroup. This web-client provides a simple way of monitoring the different versions of a package on different sources.

Technologies

• ASP.NET Core 3.0
• Blazor

How to use it

Source

• Open port 1338
• cd src/Gjallarhorn.Server
• dotnet run

Docker

docker pull haavamoa/gjallarhorn

Demonstration

When first starting the web-site you will enter a blank status-page. What you need to do is to go to edit-page and start writing JSON.

Here is a example of a potential JSON where we compare LightInject with two sources: https://api.nuget.org/v3 and <MyFakeFeedUrl>. We also set aliases to the feeds, which is a display message in the status page.

Here is the JSON

{
  "SourceComparers": [
    {
      "SourceA": "https://api.nuget.org/v3/",
      "SourceAAlias": "NuGet",
      "SourceB": "<MyFakeFeedUrl>",
      "SourceBAlias": "My fake feed",
      "Packages": [
        {
          "Name": "LightInject",
          "ComparePreRelease": true
        }
      ]
    }
  ]
}

When we press Save we jump back to the status-page, and we start fetching versions from the two feeds:

After the fetching has finished, we get a simplified view of the package status:

If we want to add more packages to this two comparing sources, we do the following:

{
  "SourceComparers": [
    {
      "SourceA": "https://api.nuget.org/v3/",
      "SourceAAlias": "NuGet",
      "SourceB": "<MyFakeFeedUrl>",
      "SourceBAlias": "My fake feed",
      "Packages": [
        {
          "Name": "LightInject",
          "ComparePreRelease": true
        },
        {
          "Name" : "Newtonsoft.Json",
          "ComparePreRelease": true
        }
      ]
    }
  ]
}

If we want to add different comparing sources, we do the following:

{
  "SourceComparers": [
    {
      "SourceA": "https://api.nuget.org/v3/",
      "SourceAAlias": "NuGet",
      "SourceB": "<MyFakeFeedUrl>",
      "SourceBAlias": "My fake feed",
      "Packages": [
        {
          "Name": "LightInject",
          "ComparePreRelease": true
        },
        {
          "Name" : "Newtonsoft.Json",
          "ComparePreRelease": true
        }
      ]
    },
    {
      "SourceA": "https://api.nuget.org/v3/",
      "SourceAAlias": "NuGet",
      "SourceB": "<AnotherFakeUrl>",
      "SourceBAlias": "My other fake feed",
      "Packages": [
        {
          "Name": "LightInject",
          "ComparePreRelease": true
        },
        {
          "Name" : "Newtonsoft.Json",
          "ComparePreRelease": true
        }
      ]
    }

  ]
}

Options when creating JSON in edit-mode

ComparePrerelease is optional, and is set to false if left empty.
