Page resources

Page resources are only accessible from page bundles, those directories with index.md or _index.md files at their root. Page resources are only available to the page with which they are bundled.

In this example, first-post is a page bundle with access to 10 page resources including audio, data, documents, images, and video. Although second-post is also a page bundle, it has no page resources and is unable to directly access the page resources associated with first-post.

Properties

ResourceType

The main type of the resource’s Media Type. For example, a file of MIME type image/jpeg has the ResourceType image. A Page will have ResourceType with value page.

Name

Default value is the file name (relative to the owning page). Can be set in front matter.

Title

Default value is the same as .Name. Can be set in front matter.

Permalink

The absolute URL to the resource. Resources of type page will have no value.

RelPermalink

The relative URL to the resource. Resources of type page will have no value.

Content

The content of the resource itself. For most resources, this returns a string with the contents of the file. Use this to create inline resources.

{{ with .Resources.GetMatch "script.js" }}
  <script>{{ .Content | safeJS }}</script>
{{ end }}

{{ with .Resources.GetMatch "style.css" }}
  <style>{{ .Content | safeCSS }}</style>
{{ end }}

{{ with .Resources.GetMatch "img.png" }}
  <img src="data:{{ .MediaType.Type }};base64,{{ .Content | base64Encode }}">
{{ end }}

MediaType.Type

The media type (formerly known as a MIME type) of the resource (e.g., image/jpeg).

MediaType.MainType

The main type of the resource’s media type (e.g., image).

MediaType.SubType

The subtype of the resource’s type (e.g., jpeg). This may or may not correspond to the file suffix.

MediaType.Suffixes

A slice of possible file suffixes for the resource’s media type (e.g., [jpg jpeg jpe jif jfif]).

Methods

ByType

Returns the page resources of the given type.

{{ .Resources.ByType "image" }}

Match

Returns all the page resources (as a slice) whose Name matches the given Glob pattern (examples). The matching is case-insensitive.

{{ .Resources.Match "images/*" }}

GetMatch

Same as Match but will return the first match.

Pattern matching

// Using Match/GetMatch to find this images/sunset.jpg ?
.Resources.Match "images/sun*" ✅
.Resources.Match "**/sunset.jpg" ✅
.Resources.Match "images/*.jpg" ✅
.Resources.Match "**.jpg" ✅
.Resources.Match "*" 🚫
.Resources.Match "sunset.jpg" 🚫
.Resources.Match "*sunset.jpg" 🚫

Metadata

The page resources’ metadata is managed from the corresponding page’s front matter with an array/table parameter named resources. You can batch assign values using wildcards.

name

Sets the value returned in Name.

title

Sets the value returned in Title

params

A map of custom key-value pairs.

date: "2018-01-25"
resources:
- name: header

date = '2018-01-25'
title = 'Application'
[[resources]]
  name = 'header'
  src = 'images/sunset.jpg'
[[resources]]
  src = 'documents/photo_specs.pdf'
  title = 'Photo Specifications'
  [resources.params]
    icon = 'photo'
[[resources]]
  src = 'documents/guide.pdf'
  title = 'Instruction Guide'
[[resources]]
  src = 'documents/checklist.pdf'
  title = 'Document Checklist'

{
   "date": "2018-01-25",
   "resources": [
      {
         "name": "header",
         "src": "images/sunset.jpg"
      },
      {
         "params": {
            "icon": "photo"
         },
         "src": "documents/photo_specs.pdf",
         "title": "Photo Specifications"
      },
      {
         "src": "documents/guide.pdf",
         "title": "Instruction Guide"
      },
      {
         "src": "documents/checklist.pdf",
         "title": "Document Checklist"
      },
      {
         "src": "documents/payment.docx",
         "title": "Proof of Payment"
      },
      {
         "name": "pdf-file-:counter",
         "params": {
            "icon": "pdf"
         },
         "src": "**.pdf"
      },
      {
         "params": {
            "icon": "word"
         },
         "src": "**.docx"
      }
   ],
   "title": "Application"
}

From the example above:

• sunset.jpg will receive a new Name and can now be found with .GetMatch "header".
• documents/photo_specs.pdf will get the photo icon.
• documents/checklist.pdf, documents/guide.pdf and documents/payment.docx will get Title as set by title.
• Every PDF in the bundle except documents/photo_specs.pdf will get the pdf icon.
• All PDF files will get a new Name. The name parameter contains a special placeholder :counter, so the Name will be pdf-file-1, pdf-file-2, pdf-file-3.
• Every docx in the bundle will receive the word icon.

The :counter placeholder in name and title

The :counter is a special placeholder recognized in name and title parameters resources.

The counter starts at 1 the first time they are used in either name or title.

For example, if a bundle has the resources photo_specs.pdf, other_specs.pdf, guide.pdf and checklist.pdf, and the front matter has specified the resources as:

---
resources:
- src: '*specs.pdf'
  title: 'Specification #:counter'
- name: pdf-file-:counter
  src: '**.pdf'
title: Engine inspections
---

+++
title = 'Engine inspections'
[[resources]]
  src = '*specs.pdf'
  title = 'Specification #:counter'
[[resources]]
  name = 'pdf-file-:counter'
  src = '**.pdf'
+++

{
   "resources": [
      {
         "src": "*specs.pdf",
         "title": "Specification #:counter"
      },
      {
         "name": "pdf-file-:counter",
         "src": "**.pdf"
      }
   ],
   "title": "Engine inspections"
}

the Name and Title will be assigned to the resource files as follows:

Multilingual

By default, with a multilingual single-host site, Hugo does not duplicate shared page resources when building the site.

Consider this site configuration:

defaultContentLanguage: de
defaultContentLanguageInSubdir: true
languages:
  de:
    languageCode: de-DE
    languageName: Deutsch
    weight: 1
  en:
    languageCode: en-US
    languageName: English
    weight: 2

defaultContentLanguage = 'de'
defaultContentLanguageInSubdir = true
[languages]
  [languages.de]
    languageCode = 'de-DE'
    languageName = 'Deutsch'
    weight = 1
  [languages.en]
    languageCode = 'en-US'
    languageName = 'English'
    weight = 2

{
   "defaultContentLanguage": "de",
   "defaultContentLanguageInSubdir": true,
   "languages": {
      "de": {
         "languageCode": "de-DE",
         "languageName": "Deutsch",
         "weight": 1
      },
      "en": {
         "languageCode": "en-US",
         "languageName": "English",
         "weight": 2
      }
   }
}

And this content:

content/
└── my-bundle/
    ├── a.jpg     <-- shared page resource
    ├── b.jpg     <-- shared page resource
    ├── c.de.jpg
    ├── c.en.jpg
    ├── index.de.md
    └── index.en.md

With v0.122.0 and earlier, Hugo duplicated the shared page resources, creating copies for each language:

public/
├── de/
│   ├── my-bundle/
│   │   ├── a.jpg     <-- shared page resource
│   │   ├── b.jpg     <-- shared page resource
│   │   ├── c.de.jpg
│   │   └── index.html
│   └── index.html
├── en/
│   ├── my-bundle/
│   │   ├── a.jpg     <-- shared page resource (duplicate)
│   │   ├── b.jpg     <-- shared page resource (duplicate)
│   │   ├── c.en.jpg
│   │   └── index.html
│   └── index.html
└── index.html

With v0.123.0 and later, Hugo places the shared resources in the page bundle for the default content language:

public/
├── de/
│   ├── my-bundle/
│   │   ├── a.jpg     <-- shared page resource
│   │   ├── b.jpg     <-- shared page resource
│   │   ├── c.de.jpg
│   │   └── index.html
│   └── index.html
├── en/
│   ├── my-bundle/
│   │   ├── c.en.jpg
│   │   └── index.html
│   └── index.html
└── index.html

This approach reduces build times, storage requirements, bandwidth consumption, and deployment times, ultimately reducing cost.

Although duplicating shared page resources is inefficient, you can enable this feature in your site configuration if desired:

markup:
  goldmark:
    duplicateResourceFiles: true

[markup]
  [markup.goldmark]
    duplicateResourceFiles = true

{
   "markup": {
      "goldmark": {
         "duplicateResourceFiles": true
      }
   }
}
