How to Use

(This is a base utilisation, all options are listed after)

This plugin will allow you to create a sitemap tree to organize your urls.

Let's start with a simple exemple : We have a recipe site like ChefClub which means that we have a lot of recipes organized in categories and so, in our dataLayer, we have the two corresponding collections : allRecipes and allCategories

We want a sitemap tree like this :

So our config will look like this :

// In your gatsby-config.js
siteMetadata: {
  siteUrl: `https://www.example.com`,
},
plugins: [
  {
    resolve : "gatsby-plugin-complex-sitemap-tree",
    options: {
      query: `
        MyRecipes : allRecipes {
            edges {
                node {
                    id
                    slug
                    last_comment_date
                    video_url
                }
            }
        }
        allCategories {
            edges {
                node {
                    id
                    slug
                    last_new_recipe
                }
            }
        }
      `,
      sitemapTree : {
        fileName: "sitemap.xml",
        children: [
          {
            fileName: "sitemap-categories.xml",
            queryName: "allCategories",
            serializer: (edge) => ({loc : edge.slug, lastmod : edge.last_new_recipe})
          },
          {
            fileName: "sitemap-recipes.xml",
            queryName: "MyRecipes",
            serializer: (edge) => ({loc : edge.slug, lastmod : edge.last_comment_date})
          },
        ],
      },
    },
  }
]

Options

Plugin options

Required	Name	Description	Default	Example
	query	The GraphQL query to get information from the data layer	allSitePage { nodes { path } }	See "Default" column
✅	sitemapTree	The sitemap tree object (See Sitemap tree options below)		(See Sitemap tree options below)
	outputFolder	The output folder from the public folder		sitemaps_folder will export all sitemaps like this public/sitemaps_folder/my-sitemap.xml

Sitemap tree options

⚠️ These options goes into the sitemapTree object of the plugin options.

The sitemapTree object is "recursive" : children contain other sitemapTree objects which form the tree at the end. There is no depth limit.

Each sitemapTree object leads to one file except in the case where the limit is exceeded, which splits the file.

Required	Name	Description	Default	Example
✅	fileName	The name of the sitemap file. Should match with this regular expression/.*\.xml$/		sitemap.xml
	outputFolder	The path to the output folder, from the parent one		recipes_sitemaps_folder
	xslPath	Override the Plugin Option xslPath option		recipe-sitemap.xsl
	lastmod	Value of the \<lastmod> anchor next to the \<loc> one		2022-02-02
	children	Array of sitemapTree object	[]
	queryName	Name of the query from the Plugin Option query option. (⚠️ Needed if serializer is defined)		MyRecipes
	serializer	Function that take the raw queryName results data and should return an object with at least a loc attribute. For more detail see XML generation. (⚠️ Needed if queryName is defined)
	filterPages	Function that take the raw queryName results data and should true to keep this node or false to remove this node
	xmlAnchorAttributes	Attributes to add <?xml {here} ?>	version="1.0" encoding="UTF-8"
	urlsetAnchorAttributes	Attributes to add <urlset {here} >	xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"	xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:image="http://www.google.com/schemas/sitemap-image/1.1" xmlns:video="http://www.google.com/schemas/sitemap-video/1.1"
	sitemapindexAnchorAttributes	Attributes to add <sitemap {here} >	xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"

Clarification

XML generation

The serializer option should return an object with at least a loc attribute but can return a lot more.

For example we can return

{
    loc : "/en-us/recipes/margherita",
    lastmod : "2022-02-02T12:00:00.000Z",
    "video:video" : {
        "video:thumbnail_loc" : "https://media.example.com/margherita.png",
        "video:title" : "Margherita",
        "video:content_loc" : "https://video.example.com/margherita.mp4",
    }
}

Which will generate the following xml

<loc>https://www.example.com</loc>
<lastmode>2022-02-02T12:00:00.000Z</lastmode>
<video:video>
    <video:thumbnail_loc>https://media.example.com/margherita.png</video:thumbnail_loc>
    <video:title>Margherita</video:title>
    <video:content_loc>https://video.example.com/margherita.mp4</video:content_loc>
</video:video>

As you can see, each attribute will be converted as an xml tag. If the attribute value is an object the algorithm will be recursive
