Casko.AspNetCore.XmlSiteMaps 2.0.0

XML Sitemaps

Zero config XML sitemaps. A thing for creating XML sitemaps in AspNetCore applications.

Get started

Follow these instructions to get started.

Install

dotnet add package Casko.AspNetCore.XmlSiteMaps --version 1.0.0

Configure

In Startup.cs or Program.cs, add XML sitemaps on IServiceCollection:

services.AddXmlSiteMaps();

In Startup.cs or Program.cs, use XML sitemaps on IApplicationBuilder:

app.UseXmlSiteMaps(addRewrites: true); // true is default

If ordering creates problems for rewrites then set useRewrites: false and then call where it fit in:

app.UseXmlSiteMapsRewrites();

After configuring XmlSiteMaps, then implementations of IXmlSiteMap<XmlSiteMapIndex>, IXmlSiteMap<XmlSiteMap>, IXmlSiteMapCollection<XmlSiteMap> and IXmlSiteMapCollection<XmlSiteMapIndex> will be picked up on application startup and endpoints and rewrites will be setup.

XML sitemaps will be served from api/xml-sitemaps/... and URL rewrites will be created and point FileName to it's corresponding endpoint.

Implement

Example code for creating different XML sitemap things.

Create a single XML sitemap:

Simplest for of XML sitemap.

public class XmlSiteMapService : IXmlSiteMap<XmlSiteMap>
{
    public string FileName => "sitemap.xml";

    public XmlSiteMap GetXmlSiteMap()
    {
        var xmlSiteMap = new XmlSiteMap();
        
        xmlSiteMap.Urls.Add(new XmlSiteMapUrl()
        {
            Location = "https://...",
            LastModified = DateTime.UtcNow,
            ChangeFrequency = ChangeFrequency.Daily,
            Priority = .5
        });

        ...

        return xmlSiteMap;
    }
}

Create a XML sitemap index:

When multiple XML sitemaps exist you will need at least one XML sitemap index.

public class XmlSiteMapIndexService : IXmlSiteMap<XmlSiteMapIndex>
{
    public string FileName => "sitemap.xml";

    public XmlSiteMapIndex GetXmlSiteMap()
    {
        var xmlSiteMapIndex = new XmlSiteMapIndex();
        
        xmlSiteMap.Locations.Add(new XmlSiteMapIndexLocation()
        {
            Location = "https://...",
        });

        ...

        return xmlSiteMapIndex;
    }
}

Create XML sitemap collection:

Create many XML sitemaps with a single implementation.

public class XmlSiteMapCollectionService() : IXmlSiteMapCollection<XmlSiteMap>
{
    public IDictionary<string, string> Routes => new Dictionary<string, string>()
    {
        { "en", "sitemap-collection-default.xml" },
        { "da", "sitemap-collection-da.xml" },
        { "es", "sitemap-collection-es.xml" },
    };

    public XmlSiteMap GetXmlSiteMap(string key)
    {
        var xmlSiteMap = new XmlSiteMap();

        ...Create things using "key"
        
        xmlSiteMap.Urls.Add(new XmlSiteMapUrl()
        {
            Location = $"https://...{key}",
            LastModified = DateTime.UtcNow,
            ChangeFrequency = ChangeFrequency.Daily,
            Priority = .5
        });
        
        return xmlSiteMap;
    }
}
