Configuration file

Create a site configuration file in the root of your project directory, naming it hugo.toml, hugo.yaml, or hugo.json, with that order of precedence.

my-project/
└── hugo.toml

{{% note %}} With v0.109.0 and earlier the basename of the site configuration file was config instead of hugo. You can use either, but should transition to the new naming convention when practical. {{% /note %}}

A simple example:

{{< code-toggle file=hugo >}} baseURL = 'https://example.org/' languageCode = 'en-us' title = 'ABC Widgets, Inc.' [params] subtitle = 'The Best Widgets on Earth' [params.contact] email = 'info@example.org' phone = '+1 202-555-1212' {{< /code-toggle >}}

To use a different configuration file when building your site, use the --config flag:

hugo --config other.toml

Combine two or more configuration files, with left-to-right precedence:

hugo --config a.toml,b.yaml,c.json

{{% note %}} See the specifications for each file format: TOML, YAML, and JSON.

{{% /note %}}

Configuration directory

Instead of a single site configuration file, split your configuration by environment, root configuration key, and language. For example:

my-project/
└── config/
    ├── _default/
    │   ├── hugo.toml
    │   ├── menus.en.toml
    │   ├── menus.de.toml
    │   └── params.toml
    └── production/
        └── params.toml

The root configuration keys are build, caches, cascade, deployment, frontmatter, imaging, languages, markup, mediatypes, menus, minify, module, outputformats, outputs, params, permalinks, privacy, related, security, segments, server, services, sitemap, and taxonomies.

Omit the root key

When splitting the configuration by root key, omit the root key in the given file. For example, these are equivalent:

{{< code-toggle file=hugo >}} [params] foo = 'bar' {{< /code-toggle >}}

{{< code-toggle file=params >}} foo = 'bar' {{< /code-toggle >}}

Recursive parsing

Hugo parses the config directory recursively, allowing you to organize the files into subdirectories. For example:

my-project/
└── config/
    └── _default/
        ├── navigation/
        │   ├── menus.de.toml
        │   └── menus.en.toml
        └── hugo.toml

Example

my-project/
└── config/
    ├── _default/
    │   ├── hugo.toml
    │   ├── menus.en.toml
    │   ├── menus.de.toml
    │   └── params.toml
    ├── production/
    │   ├── hugo.toml
    │   └── params.toml
    └── staging/
        ├── hugo.toml
        └── params.toml

Considering the structure above, when running hugo --environment staging, Hugo will use every setting from config/_default and merge staging's on top of those.

Let's take an example to understand this better. Let's say you are using Google Analytics for your website. This requires you to specify a Google tag ID in your site configuration:

{{< code-toggle file=hugo copy=false >}} [services.googleAnalytics] ID = 'G-XXXXXXXXX' {{< /code-toggle >}}

Now consider the following scenario:

  1. You don't want to load the analytics code when running hugo server.

  2. You want to use different Google tag IDs for your production and staging environments. For example:

    • G-PPPPPPPPP for production
    • G-SSSSSSSSS for staging

To satisfy these requirements, configure your site as follows:

  1. config/_default/hugo.toml

    Exclude the services.googleAnalytics section. This will prevent loading of the analytics code when you run hugo server.

    By default, Hugo sets its environment to development when running hugo server. In the absence of a config/development directory, Hugo uses the config/_default directory.

  2. config/production/hugo.toml

    Include this section only:

    {{< code-toggle file=hugo copy=false >}} [services.googleAnalytics] ID = 'G-PPPPPPPPP' {{< /code-toggle >}}

    You do not need to include other parameters in this file. Include only those parameters that are specific to your production environment. Hugo will merge these parameters with the default configuration.

    By default, Hugo sets its environment to production when running hugo. The analytics code will use the G-PPPPPPPPP tag ID.

  3. config/staging/hugo.toml

    Include this section only:

    {{< code-toggle file=hugo copy=false >}} [services.googleAnalytics] ID = 'G-SSSSSSSSS' {{< /code-toggle >}}

    You do not need to include other parameters in this file. Include only those parameters that are specific to your staging environment. Hugo will merge these parameters with the default configuration.

    To build your staging site, run hugo --environment staging. The analytics code will use the G-SSSSSSSSS tag ID.

Merge configuration from themes

The configuration value for _merge can be one of:

none
No merge.
shallow
Only add values for new keys.
deep
Add values for new keys, merge existing.

Note that you don't need to be so verbose as in the default setup below; a _merge value higher up will be inherited if not set.

{{< code-toggle file=hugo dataKey="config_helpers.mergeStrategy" skipHeader=true />}}

All configuration settings

archetypeDir

(string) The directory where Hugo finds archetype files (content templates). Default is archetypes. {{% module-mounts-note %}}

(bool) Whether to capitalize automatic list titles. Applicable to section, taxonomy, and term pages. Default is true. You can change the capitalization style in your site configuration to one of ap, chicago, go, firstupper, or none. See details.

cascade

Pass down default configuration values (front matter) to pages in the content tree. The options in site config is the same as in page front matter, see Front Matter Cascade.

{{% note %}} For a website in a single language, define the [[cascade]] in Front Matter. For a multilingual website, define the [[cascade]] in Site Config.

To remain consistent and prevent unexpected behavior, do not mix these strategies. {{% /note %}}

languageCode

(string) A language tag as defined by RFC 5646. This value is used to populate:

  • The <language> element in the embedded [RSS template]({{% eturl rss %}})
  • The lang attribute of the <html> element in the embedded [alias template]({{% eturl alias %}})
  • The og:locale meta element in the embedded [Open Graph template]({{% eturl opengraph %}})

When present in the root of the configuration, this value is ignored if one or more language keys exists. Please specify this value independently for each language key.

(bool) Whether to log WARNINGs when Hugo publishes two or more files to the same path. Default is false.

printUnusedTemplates

(bool) Whether to log WARNINGs for each unused template. Default is false.

publishDir

(string) The directory to where Hugo will write the final static site (the HTML files etc.). Default is public.

refLinksNotFoundURL

(string) URL to be used as a placeholder when a page reference cannot be found in ref or relref. Is used as-is.

See Related Content.

relativeURLs

(bool) See details before enabling this feature. Default is false.

(bool) Whether to print template execution metrics to the console. Default is false. See Template metrics.

templateMetricsHints

(bool) Whether to print template execution improvement hints to the console. Applicable when templateMetrics is true. Default is false. See Template metrics.

theme

See module configuration for how to import a theme.

themesDir

(string) The directory where Hugo reads the themes from. Default is themes.

timeout

(string) Timeout for generating page contents, specified as a duration or in seconds. Note: this is used to bail out of recursive content generation. You might need to raise this limit if your pages are slow to generate (e.g., because they require large image processing or depend on remote contents). Default is 30s.

timeZone

(string) The time zone used to parse dates without time zone offsets, including front matter date fields and values passed to the time.AsTime and time.Format template functions. The list of valid values may be system dependent, but should include UTC, Local, and any location in the IANA Time Zone Database. For example, America/Los_Angeles and Europe/Oslo are valid time zones.

title

(string) Site title.

titleCaseStyle

(string) Default is ap. See Configure Title Case.

uglyURLs

(bool or map) Whether to generate uglyURLs. Default is false. See details.

watch

(bool) Watch filesystem for changes and recreate as needed. Default is false.

{{% note %}} If you are developing your site on a *nix machine, here is a handy shortcut for finding a configuration option from the command line:

cd ~/sites/yourhugosite
hugo config | grep emoji

which shows output like

enableemoji: true

{{% /note %}}

Configure page

{{< new-in 0.133.0 >}}

These methods on a Page object navigate to the next or previous page within a page collection, relative to the current page:

Hugo determines the next and previous page by sorting a page collection according to this sorting hierarchy:

Field Precedence Sort direction
weight 1 descending
date 2 descending
linkTitle 3 descending
path 4 descending

The sort direction in the table above corresponds to these default site configuration values:

{{< code-toggle config=page />}}

To sort all fields in ascending order:

{{< code-toggle file=hugo >}} [page] nextPrevInSectionSortOrder = 'asc' nextPrevSortOrder = 'asc' {{< /code-toggle >}}

{{% note %}} These settings do not apply to the Next or Prev methods on a Pages object.

{{% /note %}}

Configure build

See Configure Build.

Configure server

This is only relevant when running hugo server, and it allows to set HTTP headers during development, which allows you to test out your Content Security Policy and similar. The configuration format matches Netlify's with slightly more powerful Glob matching:

{{< code-toggle file=hugo >}} [server] server.headers for = "/**"

[server.headers.values] X-Frame-Options = "DENY" X-XSS-Protection = "1; mode=block" X-Content-Type-Options = "nosniff" Referrer-Policy = "strict-origin-when-cross-origin" Content-Security-Policy = "script-src localhost:1313" {{< /code-toggle >}}

Since this is "development only", it may make sense to put it below the development environment:

{{< code-toggle file=config/development/server >}} headers for = "/**"

[headers.values] X-Frame-Options = "DENY" X-XSS-Protection = "1; mode=block" X-Content-Type-Options = "nosniff" Referrer-Policy = "strict-origin-when-cross-origin" Content-Security-Policy = "script-src localhost:1313" {{< /code-toggle >}}

You can also specify simple redirects rules for the server. The syntax is again similar to Netlify's.

Note that a status code of 200 will trigger a URL rewrite, which is what you want in SPA situations, e.g:

{{< code-toggle file=config/development/server >}} redirects from = "/myspa/**" to = "/myspa/" status = 200 force = false {{< /code-toggle >}}

Setting force=true will make a redirect even if there is existing content in the path. Note that before Hugo 0.76 force was the default behavior, but this is inline with how Netlify does it.

404 server error page

Hugo will, by default, render all 404 errors when running hugo server with the 404.html template. Note that if you have already added one or more redirects to your server configuration, you need to add the 404 redirect explicitly, e.g:

{{< code-toggle file=config/development/server >}} redirects from = "/**" to = "/404.html" status = 404 {{< /code-toggle >}}

With a multilingual site, define the redirect for the default content language last:

{{< code-toggle file=config/development/server >}} defaultContentLanguage = 'en' defaultContentLanguageInSubdir = false redirects from = '/fr/**' to = '/fr/404.html' status = 404

redirects # Default language must be last. from = '/**' to = '/404.html' status = 404 {{< /code-toggle >}}

If you are serving the default content language from a subdirectory:

{{< code-toggle file=config/development/server >}} defaultContentLanguage = 'en' defaultContentLanguageInSubdir = true redirects from = '/fr/**' to = '/fr/404.html' status = 404

redirects # Default language must be last. from = '/**' to = '/en/404.html' status = 404 {{< /code-toggle >}}

Configure title case

By default, Hugo follows the capitalization rules published in the Associated Press Stylebook when creating automatic section titles, and when transforming strings with the strings.Title function.

Change this behavior by setting titleCaseStyle in your site configuration to any of the values below:

ap
Use the capitalization rules published in the Associated Press Stylebook.
chicago
Use the capitalization rules published in the Chicago Manual of Style.
go
Capitalize the first letter of every word.
firstupper
Capitalize the first letter of the first word.
none
Disable transformation of automatic section titles, and disable the transformation performed by the strings.Title function. This is useful if you would prefer to manually capitalize section titles as needed, and to bypass opinionated theme usage of the strings.Title function.

Configuration environment variables

DART_SASS_BINARY
(string) The absolute path to the Dart Sass executable. By default, Hugo searches for the executable in each of the paths in the PATH environment variable.
HUGO_ENVIRONMENT
(string) Overrides the default environment, typically one of development, staging, or production.
HUGO_FILE_LOG_FORMAT
(string) A format string for the file path, line number, and column number displayed when reporting errors, or when calling the Position method from a shortcode or Markdown render hook. Valid tokens are :file, :line, and :col. Default is :file::line::col.

{{< new-in 0.123.0 >}}

HUGO_MEMORYLIMIT
(int) The maximum amount of system memory, in gigabytes, that Hugo can use while rendering your site. Default is 25% of total system memory.
HUGO_NUMWORKERMULTIPLIER
(int) The number of workers used in parallel processing. Default is the number of logical CPUs.

Configure with environment variables

Configuration key-values can be defined through operating system environment variables.

For example, the following command will effectively set a website's title on Unix-like systems:

$ env HUGO_TITLE="Some Title" hugo

This is really useful if you use a service such as Netlify to deploy your site. Look at the Hugo docs Netlify configuration file for an example.

{{% note %}} Names must be prefixed with HUGO_ and the configuration key must be set in uppercase when setting operating system environment variables.

To set configuration parameters, prefix the name with HUGO_PARAMS_ {{% /note %}}

If you are using snake_cased variable names, the above will not work. Hugo determines the delimiter to use by the first character after HUGO. This allows you to define environment variables on the form HUGOxPARAMSxAPI_KEY=abcdefgh, using any allowed delimiter.

Ignore content and data files when rendering

{{% note %}} This works, but we recommend you use the newer and more powerful includeFiles and excludeFiles mount options. {{% /note %}}

To exclude specific files from the content, data, and i18n directories when rendering your site, set ignoreFiles to one or more regular expressions to match against the absolute file path.

To ignore files ending with .foo or .boo:

{{< code-toggle file=hugo >}} ignoreFiles = ['.foo$', '.boo$'] {{< /code-toggle >}}

To ignore a file using the absolute file path:

{{< code-toggle file=hugo >}} ignoreFiles = ['^/home/user/project/content/test.md$'] {{< /code-toggle >}}

Configure front matter

Configure dates

Dates are important in Hugo, and you can configure how Hugo assigns dates to your content pages. You do this by adding a frontmatter section to your hugo.toml.

The default configuration is:

{{< code-toggle config=frontmatter />}}

If you, as an example, have a non-standard date parameter in some of your content, you can override the setting for date:

{{< code-toggle file=hugo >}} [frontmatter] date = ["myDate", ":default"] {{< /code-toggle >}}

The :default is a shortcut to the default settings. The above will set .Date to the date value in myDate if present, if not we will look in date,publishDate, lastmod and pick the first valid date.

In the list to the right, values starting with ":" are date handlers with a special meaning (see below). The others are just names of date parameters (case insensitive) in your front matter configuration. Also note that Hugo have some built-in aliases to the above: lastmod => modified, publishDate => pubdate, published and expiryDate => unpublishdate. With that, as an example, using pubDate as a date in front matter, will, by default, be assigned to .PublishDate.

The special date handlers are:

:fileModTime
Fetches the date from the content file's last modification timestamp.

An example:

{{< code-toggle file=hugo >}} [frontmatter] lastmod = ["lastmod", ":fileModTime", ":default"] {{< /code-toggle >}}

The above will try first to extract the value for .Lastmod starting with the lastmod front matter parameter, then the content file's modification timestamp. The last, :default should not be needed here, but Hugo will finally look for a valid date in :git, date and then publishDate.

:filename
Fetches the date from the content file's file name. For example, 2018-02-22-mypage.md will extract the date 2018-02-22. Also, if slug is not set, mypage will be used as the value for .Slug.

An example:

{{< code-toggle file=hugo >}} [frontmatter] date = [":filename", ":default"] {{< /code-toggle >}}

The above will try first to extract the value for .Date from the file name, then it will look in front matter parameters date, publishDate and lastly lastmod.

:git
This is the Git author date for the last revision of this content file. This will only be set if --enableGitInfo is set or enableGitInfo = true is set in site configuration.

Configure minify

See the tdewolff/minify project page for details.

Default configuration:

{{< code-toggle config=minify />}}

Configure file caches

Since Hugo 0.52 you can configure more than just the cacheDir. This is the default configuration:

{{< code-toggle config=caches />}}

You can override any of these cache settings in your own hugo.toml.

The keywords explained

cacheDir
(string) See Configure cacheDir.
project
(string) The base directory name of the current Hugo project. This means that, in its default setting, every project will have separated file caches, which means that when you do hugo --gc you will not touch files related to other Hugo projects running on the same PC.
resourceDir
(string) This is the value of the resourceDir configuration option.
maxAge
(string) This is the duration before a cache entry will be evicted, -1 means forever and 0 effectively turns that particular cache off. Uses Go's time.Duration, so valid values are "10s" (10 seconds), "10m" (10 minutes) and "10h" (10 hours).
dir
(string) The absolute path to where the files for this cache will be stored. Allowed starting placeholders are :cacheDir and :resourceDir (see above).

Configure cacheDir

This is the directory where Hugo by default will store its file caches. See Configure File Caches.

This can be set using the cacheDir config option or via the OS environment variable HUGO_CACHEDIR.

If this is not set, Hugo will use, in order of preference:

  1. If running on Netlify: /opt/build/cache/hugo_cache/. This means that if you run your builds on Netlify, all caches configured with :cacheDir will be saved and restored on the next build. For other CI vendors, please read their documentation. For an CircleCI example, see this configuration.
  2. In a hugo_cache directory below the OS user cache directory as defined by Go's os.UserCacheDir. On Unix systems, this is $XDG_CACHE_HOME as specified by basedir-spec-latest if non-empty, else $HOME/.cache. On MacOS, this is $HOME/Library/Caches. On Windows, this is%LocalAppData%. On Plan 9, this is $home/lib/cache. {{< new-in 0.116.0 >}}
  3. In a hugo_cache_$USER directory below the OS temp dir.

If you want to know the current value of cacheDir, you can run hugo config, e.g: hugo config | grep cachedir.

Configure HTTP cache

{{< new-in 0.127.0 >}}

Note that this configuration is currently only relevant when using the resources.GetRemote function.

The caching in Hugo is layered:

 .-----------.
|  dynacache  |
 '-----+-----'
       |
       v
 .----------.
| HTTP cache |
 '-----+----'
       |
       v
 .----------.
| file cache |
 '-----+----'
Dynacache
A in memory LRU cache that gets evicted on changes, Cache Buster matches and in low memory situations.
HTTP Cache
Enables HTTP cache behavior (RFC 9111) for remote resources. This works best for resources with properly set up HTTP cache headers. The HTTP cache uses the file cache to store and serve cached resources.
File Cache
See file cache.

The default HTTP cache disables everything:

{{< code-toggle config=HTTPCache />}}

caching
Enabled RFC 9111 cache behavior for a configured set of resources. Stale resources will be refreshed from the file cache even if their configured TTL isn't reached.
polling
Enables polling for a set of resources. Note that you can enable polling for resources even if HTTP caching is disabled. This setting is only used when in watch mode (e.g. hugo server). When a changed resource is detected, that change triggers a rebuild of pages using that resource.

Configure segments

{{< new-in 0.124.0 >}}

{{% note %}} The segments configuration is currently only used to configure partitioned rendering. This feature is only about what gets rendered when, Hugo's entire object graph (sites and pages) is always available. {{% /note %}}

  • Each segment consists of zero or more exclude filters and zero or more include filters.
  • Each filter consists of one or more field Glob matchers.
  • Each filter in a section (exclude or include) is ORed together, each matcher in a filter is ANDed together.

The fields that can be used in the filters are:

path
The logical page path.
lang
The page language.
kind
The kind of the page.
output
The output format of the page.

It is recommended to put coarse grained filters (e.g. for language and output format) in the excludes section, e.g.:

{{< code-toggle file=hugo >}} [segments.segment1] segments.segment1.excludes lang = "n*" segments.segment1.excludes lang = "en" output = "rss" segments.segment1.includes kind = "{home,term,taxonomy}" segments.segment1.includes path = "{/docs,/docs/**}" {{< /code-toggle >}}

With the above you can render only the pages in segment1 by configuring the renderSegments or setting the --renderSegments flag:

hugo --renderSegments segment1

Multiple segments can be configured, and the --renderSegments flag can take a comma separated list of segments.

Some use cases for this feature:

  • Splitting builds of big sites.
  • Enable faster builds during development by only rendering a subset of the site.
  • Partial rebuilds, e.g. render the home page and the "news section" every hour, render the entire site once a week.
  • Render only e.g. the JSON output format to push to e.g. a search index.
