Gets a path from the Request using rqPathInfo and makes sure it is safe to use for opening files. A path is safe if it is a relative path and has no .. elements to escape the intended directory structure.

A type alias for MIME type

A type alias for dynamic handlers

A collection of options for serving static files out of a directory.

A very simple configuration for directory serving. This configuration uses built-in MIME types from defaultMimeTypes, and has no index files, index generator, dynamic file handlers, or preServeHook.

A reasonable default configuration for directory serving. This configuration uses built-in MIME types from defaultMimeTypes, serves common index files index.html and index.htm, but does not autogenerate directory indexes, nor have any dynamic file handlers. The preServeHook will not do anything.

A more elaborate configuration for file serving. This configuration uses built-in MIME types from defaultMimeTypes, serves common index files index.html and index.htm, and autogenerates directory indexes with a Snap-like feel. It still has no dynamic file handlers, nor preServeHook, which should be added as needed.

Files recognized as indexes include index.html, index.htm, default.html, default.htm, home.html

An automatic index generator, which is fairly small and does not rely on any external files (which may not be there depending on external request routing).

A MimeMap is passed in to display the types of files in the directory listing based on their extension. Preferably, this is the same as the map in the DirectoryConfig

The styles parameter allows you to apply styles to the directory listing. The listing itself consists of a table, containing a header row using th elements, and one row per file using td elements, so styles for those pieces may be attached to the appropriate tags.

The default set of mime type mappings we use when serving files. Its value:

Serves static files from a directory using the default configuration as given in defaultDirectoryConfig.

Serves static files from a directory. Configuration options are passed in a DirectoryConfig that captures various choices about desired behavior. The relative path given in rqPathInfo is searched for a requested file, and the file is served with the appropriate mime type if it is found. Absolute paths and ".." are prohibited to prevent files from being served from outside the sandbox.

Serves a single file specified by a full or relative path. If the file does not exist, throws an exception (not that it does not pass to the next handler). The path restrictions on serveDirectory don't apply to this function since the path is not being supplied by the user.

Same as serveFile, with control over the MIME mapping used.
