This document describes nginx-module-fancyindex v0.5.2 released on Oct 28 2021.

Nginx Fancy Index module

The Fancy Index module makes possible the generation of file listings, like the built-in autoindex module does, but adding a touch of style. This is possible because the module allows a certain degree of customization of the generated content:

  • Custom headers. Either local or stored remotely.
  • Custom footers. Either local or stored remotely.
  • Add you own CSS style rules.
  • Allow choosing to sort elements by name (default), modification time, or size; both ascending (default), or descending.

This module is designed to work with Nginx, a high performance open source web server written by Igor Sysoev.

Requirements

CentOS 7

For users of the official stable Nginx repository, extra packages repository with dynamic modules is available and fancyindex is included.

Install directly:

yum install https://extras.getpagespeed.com/redhat/7/x86_64/RPMS/nginx-module-fancyindex-1.12.0.0.4.1-1.el7.gps.x86_64.rpm

Alternatively, add extras repository first (for future updates) and install the module:

yum install nginx-module-fancyindex

Then load the module in /etc/nginx/nginx.conf using:

load_module "modules/ngx_http_fancyindex_module.so";

Other platforms

In most other cases you will need the sources for Nginx. Any version starting from the 0.8 series should work.

In order to use the fancyindex_header_ and fancyindex_footer_ directives you will also need the ngx_http_addition_module built into Nginx.

Building

  1. Unpack the Nginx sources:

    $ gunzip -c nginx-?.?.?.tar.gz | tar -xvf -

  2. Unpack the sources for the fancy indexing module:

    $ gunzip -c nginx-fancyindex-?.?.?.tar.gz | tar -xvf -

  3. Change to the directory which contains the Nginx sources, run the configuration script with the desired options and be sure to put an --add-module flag pointing to the directory which contains the source of the fancy indexing module:

    $ cd nginx-?.?.?
$ ./configure --add-module=../nginx-fancyindex-?.?.? \
   [--with-http_addition_module] [extra desired options]

    Since version 0.4.0, the module can also be built as a dynamic module, using --add-dynamic-module=… instead and load_module "modules/ngx_http_fancyindex_module.so"; in the configuration file

  4. Build and install the software:

    $ make

    And then, as root:

    # make install

  5. Configure Nginx by using the modules' configuration directives_.

Example

You can test the default built-in style by adding the following lines into a server section in your Nginx configuration file:

location / {
  fancyindex on;              # Enable fancy indexes.
  fancyindex_exact_size off;  # Output human-readable file sizes.
}

Themes

The following themes demonstrate the level of customization which can be achieved using the module:

  • Theme by @TheInsomniac. Uses custom header and footer.
  • Theme by @Naereen. Uses custom header and footer, the header includes search field to filter by filename using JavaScript.
  • Theme by @fraoustin. Responsive theme using Material Design elements.
  • Theme by @alehaa. Simple, flat theme based on Bootstrap 4 and FontAwesome.

Directives

fancyindex

Syntax
fancyindex [on | off]

Default
fancyindex off

Context
http, server, location

Description
Enables or disables fancy directory indexes.

fancyindex_default_sort

Syntax
fancyindex_default_sort [name | size | date | name_desc | size_desc | date_desc]

Default
fancyindex_default_sort name

Context
http, server, location

Description
Defines sorting criterion by default.

fancyindex_directories_first

Syntax
fancyindex_directories_first [on | off]

Default
fancyindex_directories_first on

Context
http, server, location

Description
If enabled (default setting), groups directories together and sorts them before all regular files. If disabled, directories are sorted together with files.

fancyindex_css_href

Syntax
fancyindex_css_href uri

Default
fancyindex_css_href ""

Context
http, server, location

Description
Allows inserting a link to a CSS style sheet in generated listings. The provided uri parameter will be inserted as-is in a <link> HTML tag. The link is inserted after the built-in CSS rules, so you can override the default styles.

fancyindex_exact_size

Syntax
fancyindex_exact_size [on | off]

Default
fancyindex_exact_size on

Context
http, server, location

Description
Defines how to represent file sizes in the directory listing; either accurately, or rounding off to the kilobyte, the megabyte and the gigabyte.

fancyindex_name_length

Syntax
fancyindex_name_length length

Default
fancyindex_name_length 50

Context
http, server, location

Description
Defines the maximum file name length limit in bytes.

Syntax
fancyindex_footer path [subrequest | local]

Default
fancyindex_footer ""

Context
http, server, location

Description
Specifies which file should be inserted at the foot of directory listings. If set to an empty string, the default footer supplied by the module will be sent. The optional parameter indicates whether the path is to be treated as an URI to load using a subrequest (the default), or whether it refers to a local file.

note

Using this directive needs the ngx_http_addition_module_ built into Nginx.

warning

When inserting custom header/footer a subrequest will be issued so potentially any URL can be used as source for them. Although it will work with external URLs, only using internal ones is supported. External URLs are totally untested and using them will make Nginx block while waiting for the subrequest to complete. If you feel like external header/footer is a must-have for you, please let me know.

fancyindex_header

Syntax
fancyindex_header path [subrequest | local]

Default
fancyindex_header ""

Context
http, server, location

Description
Specifies which file should be inserted at the head of directory listings. If set to an empty string, the default header supplied by the module will be sent. The optional parameter indicates whether the path is to be treated as an URI to load using a subrequest (the default), or whether it refers to a local file.

note

Using this directive needs the ngx_http_addition_module_ built into Nginx.

fancyindex_show_path

Syntax
fancyindex_show_path [on | off]

Default
fancyindex_show_path on

Context
http, server, location

Description

warning

This directive can be turned off only if a custom header is provided using fancyindex_header.
