An index template is any template that will be used to render multiple pieces of content (with the exception of the homepage which has a dedicated template).

We are using the term index in its truest sense, a sequential arrangement of material, especially in alphabetical or numerical order. In the case of Hugo each index will render the content in newest first order based on the date provided in the front matter.

index pages are of the type "node" and have all the node variables available to use in the templates. All index templates live in the layouts/indexes directory. There are 3 different kinds of indexes that Hugo can produce.

1. A listing of all the content for a given section
2. A listing of all the content for a given index
3. A listing of listings... meta index

It's critical that the name of the index template matches either:

1. The section name
2. The index singular name
3. "indexes"

The following illustrates the location of one of each of these types.

Example section template (post.html)

This content template is used for spf13.com. It makes use of chrome templates. All examples use a view called either "li" or "summary" which this example site defined.

{{ template "chrome/header.html" . }}
{{ template "chrome/subheader.html" . }}

<section id="main">
  <div>
   <h1 id="title">{{ .Title }}</h1>
        <ul id="list">
            {{ range .Data.Pages }}
                {{ .Render "li"}}
            {{ end }}
        </ul>
  </div>
</section>

{{ template "chrome/footer.html" }}

Example index template (tag.html)

This content template is used for spf13.com. It makes use of chrome templates. All examples use a view called either "li" or "summary" which this example site defined.

{{ template "chrome/header.html" . }}
{{ template "chrome/subheader.html" . }}

<section id="main">
  <div>
   <h1 id="title">{{ .Title }}</h1>
    {{ range .Data.Pages }}
        {{ .Render "summary"}}
    {{ end }}
  </div>
</section>

{{ template "chrome/footer.html" }}

Example listing of indexes template (indexes.html)

This content template is used for spf13.com. It makes use of chrome templates. The list of indexes templates cannot use a content view as they don't display the content, but rather information about the content.

This particular template lists all of the Tags used on spf13.com and provides a count for the number of pieces of content tagged with each tag.

This example demonstrates two different approaches. The first uses .Data.Index and the latter uses .Data.OrderedIndex. .Data.Index is alphabetical by key name, while .Data.Orderedindex is ordered by the quantity of content assigned to that particular index key. In practice you would only use one of these approaches.

{{ template "chrome/header.html" . }}
{{ template "chrome/subheader.html" . }}

<section id="main">
  <div>
   <h1 id="title">{{ .Title }}</h1>

   <ul>
   {{ $data := .Data }}
    {{ range $key, $value := .Data.Index }}
    <li><a href="{{ $data.Plural }}/{{ $key | urlize }}"> {{ $key }} </a> {{ len $value }} </li>
    {{ end }}
   </ul>
  </div>

   <ul>
    {{ range $data.OrderedIndex }}
    <li><a href="{{ $data.Plural }}/{{ .Name | urlize }}"> {{ .Name }} </a> {{ .Count }} </li>
    {{ end }}
   </ul>
</section>

{{ template "chrome/footer.html" }}
