The real power of Hugo pagination shines when combined with the where function and its SQL-like operators: first, last, and after. You can even order the content the way you've become used to with Hugo.

Configure Pagination

Pagination can be configured in your site configuration:

paginate
default = 10. This setting can be overridden within the template.
paginatePath
default = page. Allows you to set a different path for your pagination pages.

Setting paginate to a positive value will split the list pages for the homepage, sections and taxonomies into chunks of that size. But note that the generation of the pagination pages for sections, taxonomies and homepage is lazy --- the pages will not be created if not referenced by a .Paginator (see below).

paginatePath is used to adapt the URL to the pages in the paginator (the default setting will produce URLs on the form /page/1/.

List Paginator Pages

{{% warning %}} .Paginator is provided to help you build a pager menu. This feature is currently only supported on homepage and list pages (i.e., taxonomies and section lists). {{% /warning %}}

There are two ways to configure and use a .Paginator:

  1. The simplest way is just to call .Paginator.Pages from a template. It will contain the pages for that page.
  2. Select another set of pages with the available template functions and ordering options, and pass the slice to .Paginate, e.g.
  • {{ range (.Paginate ( first 50 .Pages.ByTitle )).Pages }} or
  • {{ range (.Paginate .RegularPagesRecursive).Pages }}.

For a given Page, it's one of the options above. The .Paginator is static and cannot change once created.

If you call .Paginator or .Paginate multiple times on the same page, you should ensure all the calls are identical. Once either .Paginator or .Paginate is called while generating a page, its result is cached, and any subsequent similar call will reuse the cached result. This means that any such calls which do not match the first one will not behave as written.

(Remember that function arguments are eagerly evaluated, so a call like $paginator := cond x .Paginator (.Paginate .RegularPagesRecursive) is an example of what you should not do. Use if/else instead to ensure exactly one evaluation.)

The global page size setting (Paginate) can be overridden by providing a positive integer as the last argument. The examples below will give five items per page:

  • {{ range (.Paginator 5).Pages }}
  • {{ $paginator := .Paginate (where .Pages "Type" "posts") 5 }}

It is also possible to use the GroupBy functions in combination with pagination:

{{ range (.Paginate (.Pages.GroupByDate "2006")).PageGroups  }}

Build the navigation

The .Paginator contains enough information to build a paginator interface.

The easiest way to add this to your pages is to include the built-in template (with Bootstrap-compatible styles):

{{ template "_internal/pagination.html" . }}

{{% note "When to Create .Paginator" %}} If you use any filters or ordering functions to create your .Paginator and you want the navigation buttons to be shown before the page listing, you must create the .Paginator before it's used. {{% /note %}}

The following example shows how to create .Paginator before its used:

{{ $paginator := .Paginate (where .Pages "Type" "posts") }}
{{ template "_internal/pagination.html" . }}
{{ range $paginator.Pages }}
   {{ .Title }}
{{ end }}

Without the where filter, the above example is even simpler:

{{ template "_internal/pagination.html" . }}
{{ range .Paginator.Pages }}
   {{ .Title }}
{{ end }}

If you want to build custom navigation, you can do so using the .Paginator object, which includes the following properties:

PageNumber
The current page's number in the pager sequence
URL
The relative URL to the current pager
Pages
The pages in the current pager
NumberOfElements
The number of elements on this page
HasPrev
Whether there are page(s) before the current
Prev
The pager for the previous page
HasNext
Whether there are page(s) after the current
Next
The pager for the next page
First
The pager for the first page
Last
The pager for the last page
Pagers
A list of pagers that can be used to build a pagination menu
PageSize
Size of each pager
TotalPages
The number of pages in the paginator
TotalNumberOfElements
The number of elements on all pages in this paginator

Additional information

The pages are built on the following form (BLANK means no value):

[SECTION/TAXONOMY/BLANK]/index.html
[SECTION/TAXONOMY/BLANK]/page/1/index.html => redirect to  [SECTION/TAXONOMY/BLANK]/index.html
[SECTION/TAXONOMY/BLANK]/page/2/index.html
....
