NPM version Build Status Coverage Status dependencies Status

A plugin of assets and relations relating to sitemaps.

This plugin is especially useful if you intend to crawl your entire website, which might contain landing pages that are not linked to in your site navigation structure.

With this plugin, you can initialize an Assetgraph from an XML sitemap or robots.txt (with Sitemap:-directives).

Supported sitemap types:

  • XML Sitemap
  • Text Sitemap
  • Atom feed
  • RSS feed

Installation and usage

assetgraph-plugin-sitemap har a peer dependency on assetgraph

npm install --save-dev assetgraph-plugin-sitemap assetgraph

Then use the plugin by adding the sitemap extensions to an existing Assetgraph instance:

const AssetGraph = require('assetgraph');
const extendWithSitemaps = require('assetgraph-plugin-sitemap');

const graph = new AssetGraph({ root: 'https://example.com' });

extendWithSitemaps(graph);

async function main() {
  await graph.loadAssets('robots.txt', 'sitemap.xml');
  await graph.populate({
    followRelations: {
      crossorigin: false
    }
  });

  // You now have a fully populated graph based on your
  // robots.txt Sitemap:-directives and your sitemap.xml
}

main();

Additions to Assetgraph

New Assets

New Relations

  • RobotsSitemap - A relation to any sitemap format, starting from the Sitemap: directive in robots.txt
  • XmlSitemapUrl - A relation to a page, starting from the XML sitemap <loc> element
  • TextSitemapUrl - A relation to a page, starting from a URL line in TextSitemap

New behavior

robots.txt is automatically upgraded from a Text asset to a Robots asset, which also discovers the Sitemap:-directives in robots.txt and adds RobotsSitemap relations to the graph.

XML sitemaps are automatically upgraded from an Xml asset to a XmlSitemap asset based on the <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"> content. <loc> elements in the Xml sitemap automatically add XmlSitemapUrl relations to the graph.

While TextSitemap assets now exist, they cannot be automatically inferred based on their contents alone. This means that a Text asset can only be automatically upgraded to a TextSitemap asset based on an incoming RobotsSitemap relation. It is recommended to always add a Sitemap:-directive to your robots.txt and initialize your assetgraph from there in order to have TextSitemap work correctly. When a TextSitemap is inferred, TextSitemapUrl relations are added to the graph for each URL line in the text file.
