What is Nginx Autoindex

Nginx Autoindex is a feature that automatically generates an HTML page to list files in the directory when requesting a directory instead of a file.

The role of Autoindex

Autoindex is mainly used for the following purposes:

• Create basic directory navigation on the server
• Allows users to browse files in directories without uploading actual files
• Provides basic information about files and directories on the server, such as name, size, and date of modification

Autoindex configuration

To enable Autoindex, add the following directives in the Nginx configuration file:

 <code>autoindex on;</code>

You can also configure other options to customize the behavior of Autoindex, such as:

• autoindex_exact_size : Shows the exact size of the file, not the approximate value.
• autoindex_localtime : Displays file time in the local time zone, not server time.
• autoindex_format : Customize the HTML format of the Autoindex page.

Advantages of Autoindex

• Convenient to users browse the directory
• Easy to configure and use
• Provide basic information about files and directories

Disadvantages of Autoindex

• There may be security risks because directory structure and file information will be exposed.
• May affect server performance if the directory contains a large number of files.
• The appearance and feel of the Autoindex page cannot be customized.
