The above example adds one new media type, text/enriched, and changes the suffix for the built-in text/html media type.
Note: these media types are configured for your output formats. If you want to redefine one of Hugo’s default output formats (e.g. HTML), you also need to redefine the output format. So, if you want to change the suffix of the HTML output format from html (default) to htm:
[mediaTypes][mediaTypes."text/html"]suffix="htm"# Redefine HTML to update its media type.[outputFormats][outputFormats.HTML]mediaType="text/html"
Note that for the above to work, you also need to add anoutputs definition in your site config.
Given a media type and some additional configuration, you get an Output Format:
This is the full set of Hugo’s built-in output formats:
A page can be output in as many output formats as you want, and you can have an infinite amount of output formats defined as long as they resolve to a unique path on the file system. In the above table, the best example of this is AMP vs. HTML. AMP has the value amp for Path so it doesn’t overwrite the HTML version; e.g. we can now have both /index.html and /amp/index.html.
The MediaType must match the Type of an already defined media type.
You can define new output formats or redefine built-in output formats; e.g., if you want to put AMP pages in a different path.
To add or modify an output format, define it in an outputFormats section in your site’s configuration file, either for all sites or for a given language.
The above example is fictional, but if used for the homepage on a site with baseURLhttps://example.org, it will produce a plain text homepage with the URL bep://example.org/myindex.enr.
Configure Output Formats
The following is the full list of configuration options for output formats and their default values:
the output format identifier. This is used to define what output format(s) you want for your pages.
this must match the Type of a defined media type.
sub path to save the output files.
the base filename for the list filenames (homepage, etc.). Default:index.
can be used to create rel values in link tags. Default:alternate.
will replace the “http://” or “https://” in your baseURL for this output format.
use Go’s plain text templates parser for the templates. Default:false.
used in situations only relevant for HTML-type formats; e.g., page aliases.
used to turn off ugly URLs If uglyURLs is set to true in your site. Default:false.
enable if it doesn’t make sense to include this format in an AlternativeOutputFormats format listing on Page (e.g., with CSS). Note that we use the term alternative and not alternate here, as it does not necessarily replace the other format. Default:false.
Output Formats for Pages
A Page in Hugo can be rendered to multiple representations on the file system. By default, all pages will render as HTML with some of them also as RSS (homepage, sections, etc.).
This can be changed by defining an outputs list of output formats in either the Page front matter or in the site configuration (either for all sites or per language).
Example from site config.toml:
home = ["HTML", "AMP", "RSS"]
page = ["HTML"]
Hugo will now also detect the media type and output format of partials, if possible, and use that information to decide if the partial should be parsed as a plain text template or not.
Hugo will look for the name given, so you can name it whatever you want. But if you want it treated as plain text, you should use the file suffix and, if needed, the name of the Output Format. The pattern is as follows:
The partial below is a plain text template (Outpuf Format is CSV, and since this is the only output format with the suffix csv, we don’t need to include the Output Format’s Name):
