🔷 FoxLearn.AspNetCore.JsonLd

Name: FoxLearn.AspNetCore.JsonLd
Author: FoxLearn

FoxLearn.AspNetCore.JsonLd is a lightweight, easy-to-use .NET library that automatically injects JSON-LD structured data into your ASP.NET Core application. By adding JSON-LD <script> tags into your HTML , search engines like Google and Bing can better understand your content—resulting in enhanced SEO, rich snippets, and improved search visibility.

🔍 Perfect for blogs, e-commerce, and any ASP.NET Core app that needs to rank better on search engines with structured metadata.

✨ Key Features

✅ Auto-injection of structured data (application/ld+json)
🔗 Schema.org support for defining custom schemas
⚙️ Seamless ASP.NET Core integration (.NET 6+)
🚫 No manual <script> tag editing
🔍 Boosts SEO for better search result presentation (e.g., breadcrumbs, rich cards)

📦 Installation

Install via the .NET CLI:

dotnet add package FoxLearn.AspNetCore.JsonLd

Or via NuGet Package Manager

Search for FoxLearn.AspNetCore.JsonLd in Visual Studio’s NuGet UI.

⚙️ Getting Started

1. Configure Services (Program.cs or Startup.cs)

// Optional: Add default for each page

builder.Services.ConfigureJsonLd<WebSite>(options =>
{
    options.Id = "https://foxlearn.com#website";
    options.Url = new Uri("https://foxlearn.com");
    options.Name = "FoxLearn";
    options.Description = "Welcome to foxlearn.com! This site is a blog about everything that matters in the world of programming.";
    options.InLanguage = "en-US";
    options.PotentialAction = new SearchAction
    {
        Target = new Uri("https://foxlearn.com/post/search?q={search_term_string}"),
        QueryInput = "required name=search_term_string"
    };
});
builder.Services.AddJsonLd(); // Required to enable injection

2. Enable Middleware

Make sure to add UseJsonLd() in the app pipeline:

app.UseJsonLd(); // Enables automatic script injection

📚 Usage Guide

You can dynamically generate structured data using a helper service:

✅ Create a Helper Class: JsonLdGenerator

public class JsonLdGenerator
{
    private const string Hosting = "https://foxlearn.com";
    private readonly IJsonLdBuilder _jsonLdBuilder;

    public JsonLdGenerator(IJsonLdBuilder jsonLdBuilder)
    {
        _jsonLdBuilder = jsonLdBuilder;
    }

    private Uri BuildUri(string path = "") => new Uri($"{Hosting}/{path}".TrimEnd('/'));

    private Organization CreateOrganization() => new Organization
    {
        Name = "FoxLearn",
        Url = BuildUri(),
        Logo = new ImageObject()
        {
            Url = BuildUri("img/logo.png"),
        },
        Description = "Welcome to foxlearn.com! This site is a blog about everything that matters in the world of programming.",
        SameAs = new[] { new Uri("https://x.com/tanhynh"), new Uri("https://www.youtube.com/foxlearn") },
        ContactPoint = new[]
        {

            (3, obj.Title!, postPath)
        ));
    }
}

✅ Use in Controller

public class HomeController : Controller
{
    private readonly JsonLdGenerator _jsonLdGenerator;

    public HomeController(JsonLdGenerator jsonLdGenerator)
    {
        _jsonLdGenerator = jsonLdGenerator;
    }

    public async Task<IActionResult> Index(int? page)
    {
        _jsonLdGenerator.Home();
        var posts = await _postRepository.GetPagedPostsAsync(PostType.Article, page ?? 1);
        return View(posts);
    }
}

🧩 Razor Tag Integration (Alternative to Middleware)

If you prefer injecting JSON-LD tags via Razor:

1. Enable the Tag Helper

In _ViewImports.cshtml:

@addTagHelper *, FoxLearn.AspNetCore.JsonLd

2. Inject in Layout

In your main layout (e.g., _Layout.cshtml):

<head>
    ...
    <json-ld />
</head>

✅ Note: If you're using , you can remove app.UseJsonLd() from Program.cs.

✅ Use in Controller

public class HomeController : Controller
{
    private readonly JsonLdGenerator _jsonLdGenerator;

    public HomeController(JsonLdGenerator jsonLdGenerator)
    {
        _jsonLdGenerator = jsonLdGenerator;
    }

    public async Task<IActionResult> Index(int? page)
    {
        _jsonLdGenerator.Home();
        var posts = await _postRepository.GetPagedPostsAsync(PostType.Article, page ?? 1);
        return View(posts);
    }
}

🧩 Razor Tag Integration (Alternative to Middleware)

If you prefer injecting JSON-LD tags via Razor:

1. Enable the Tag Helper

In _ViewImports.cshtml:

@addTagHelper *, FoxLearn.AspNetCore.JsonLd

2. Inject in Layout

In your main layout (e.g., _Layout.cshtml):

<head>
    ...
    <json-ld />
</head>

✅ Note: If you're using , you can remove app.UseJsonLd() from Program.cs.
