NAME

       Catalyst::Plugin::Static::Simple - Make serving static pages painless.

SYNOPSIS

           package MyApp;
           use Catalyst qw/ Static::Simple /;
           MyApp->setup;
           # that's it; static content is automatically served by Catalyst
           # from the application's root directory, though you can configure
           # things or bypass Catalyst entirely in a production environment
           #
           # one caveat: the files must be served from an absolute path
           # (i.e. /images/foo.png)

DESCRIPTION

       The Static::Simple plugin is designed to make serving static content in your application
       during development quick and easy, without requiring a single line of code from you.

       This plugin detects static files by looking at the file extension in the URL (such as .css
       or .png or .js). The plugin uses the lightweight MIME::Types module to map file extensions
       to IANA-registered MIME types, and will serve your static files with the correct MIME type
       directly to the browser, without being processed through Catalyst.

       Note that actions mapped to paths using periods (.) will still operate properly.

       If the plugin can not find the file, the request is dispatched to your application
       instead. This means you are responsible for generating a 404 error if your applicaton can
       not process the request:

          # handled by static::simple, not dispatched to your application
          /images/exists.png

          # static::simple will not find the file and let your application
          # handle the request. You are responsible for generating a file
          # or returning a 404 error
          /images/does_not_exist.png

       Though Static::Simple is designed to work out-of-the-box, you can tweak the operation by
       adding various configuration options. In a production environment, you will probably want
       to use your webserver to deliver static content; for an example see "USING WITH APACHE",
       below.

DEFAULT BEHAVIOUR

       By default, Static::Simple will deliver all files having extensions (that is, bits of text
       following a period (".")), except files having the extensions "tmpl", "tt", "tt2", "html",
       and "xhtml". These files, and all files without extensions, will be processed through
       Catalyst. If MIME::Types doesn't recognize an extension, it will be served as
       "text/plain".

       To restate: files having the extensions "tmpl", "tt", "tt2", "html", and "xhtml" will not
       be served statically by default, they will be processed by Catalyst. Thus if you want to
       use ".html" files from within a Catalyst app as static files, you need to change the
       configuration of Static::Simple. Note also that files having any other extension will be
       served statically, so if you're using any other extension for template files, you should
       also change the configuration.

       Logging of static files is turned off by default.

ADVANCED CONFIGURATION

       Configuration is completely optional and is specified within "MyApp->config->{static}".
       If you use any of these options, this module will probably feel less "simple" to you!

   Enabling request logging
       Since Catalyst 5.50, logging of static requests is turned off by default; static requests
       tend to clutter the log output and rarely reveal anything useful. However, if you want to
       enable logging of static requests, you can do so by setting
       "MyApp->config->{static}->{logging}" to 1.

   Forcing directories into static mode
       Define a list of top-level directories beneath your 'root' directory that should always be
       served in static mode.  Regular expressions may be specified using "qr//".

           MyApp->config(
               static => {
                   dirs => [
                       'static',
                       qr/^(images|css)/,
                   ],
               }
           );

   Including additional directories
       You may specify a list of directories in which to search for your static files. The
       directories will be searched in order and will return the first file found. Note that your
       root directory is not automatically added to the search path when you specify an
       "include_path". You should use "MyApp->config->{root}" to add it.

           MyApp->config(
               static => {
                   include_path => [
                       '/path/to/overlay',
                       \&incpath_generator,
                       MyApp->config->{root},
                   ],
               },
           );

       With the above setting, a request for the file "/images/logo.jpg" will search for the
       following files, returning the first one found:

           /path/to/overlay/images/logo.jpg
           /dynamic/path/images/logo.jpg
           /your/app/home/root/images/logo.jpg

       The include path can contain a subroutine reference to dynamically return a list of
       available directories.  This method will receive the $c object as a parameter and should
       return a reference to a list of directories.  Errors can be reported using "die()".  This
       method will be called every time a file is requested that appears to be a static file
       (i.e. it has an extension).

       For example:

           sub incpath_generator {
               my $c = shift;

               if ( $c->session->{customer_dir} ) {
                   return [ $c->session->{customer_dir} ];
               } else {
                   die "No customer dir defined.";
               }
           }

   Ignoring certain types of files
       There are some file types you may not wish to serve as static files.  Most important in
       this category are your raw template files.  By default, files with the extensions "tmpl",
       "tt", "tt2", "html", and "xhtml" will be ignored by Static::Simple in the interest of
       security.  If you wish to define your own extensions to ignore, use the
       "ignore_extensions" option:

           MyApp->config(
               static => {
                   ignore_extensions => [ qw/html asp php/ ],
               },
           );

   Ignoring entire directories
       To prevent an entire directory from being served statically, you can use the "ignore_dirs"
       option.  This option contains a list of relative directory paths to ignore.  If using
       "include_path", the path will be checked against every included path.

           MyApp->config(
               static => {
                   ignore_dirs => [ qw/tmpl css/ ],
               },
           );

       For example, if combined with the above "include_path" setting, this "ignore_dirs" value
       will ignore the following directories if they exist:

           /path/to/overlay/tmpl
           /path/to/overlay/css
           /dynamic/path/tmpl
           /dynamic/path/css
           /your/app/home/root/tmpl
           /your/app/home/root/css

   Custom MIME types
       To override or add to the default MIME types set by the MIME::Types module, you may enter
       your own extension to MIME type mapping.

           MyApp->config(
               static => {
                   mime_types => {
                       jpg => 'image/jpg',
                       png => 'image/png',
                   },
               },
           );

   Controlling caching with Expires header
       The files served by Static::Simple will have a Last-Modified header set, which allows some
       browsers to cache them for a while. However if you want to explicitly set an Expires
       header, such as to allow proxies to cache your static content, then you can do so by
       setting the "expires" config option.

       The value indicates the number of seconds after access time to allow caching.  So a value
       of zero really means "don't cache at all", and any higher values will keep the file around
       for that long.

           MyApp->config(
               static => {
                   expires => 3600, # Caching allowed for one hour.
               },
           );

   Compatibility with other plugins
       Since version 0.12, Static::Simple plays nice with other plugins.  It no longer short-
       circuits the "prepare_action" stage as it was causing too many compatibility issues with
       other plugins.

   Debugging information
       Enable additional debugging information printed in the Catalyst log.  This is
       automatically enabled when running Catalyst in -Debug mode.

           MyApp->config(
               static => {
                   debug => 1,
               },
           );

USING WITH APACHE

       While Static::Simple will work just fine serving files through Catalyst in mod_perl, for
       increased performance you may wish to have Apache handle the serving of your static files
       directly. To do this, simply use a dedicated directory for your static files and configure
       an Apache Location block for that directory  This approach is recommended for production
       installations.

           <Location /myapp/static>
               SetHandler default-handler
           </Location>

       Using this approach Apache will bypass any handling of these directories through Catalyst.
       You can leave Static::Simple as part of your application, and it will continue to function
       on a development server, or using Catalyst's built-in server.

       In practice, your Catalyst application is probably (i.e. should be) structured in the
       recommended way (i.e., that generated by bootstrapping the application with the
       "catalyst.pl" script, with a main directory under which is a "lib/" directory for module
       files and a "root/" directory for templates and static files). Thus, unless you break up
       this structure when deploying your app by moving the static files to a different location
       in your filesystem, you will need to use an Alias directive in Apache to point to the
       right place. You will then need to add a Directory block to give permission for Apache to
       serve these files. The final configuration will look something like this:

           Alias /myapp/static /filesystem/path/to/MyApp/root/static
           <Directory /filesystem/path/to/MyApp/root/static>
               allow from all
           </Directory>
           <Location /myapp/static>
               SetHandler default-handler
           </Location>

       If you are running in a VirtualHost, you can just set the DocumentRoot location to the
       location of your root directory; see Catalyst::Engine::Apache2::MP20.

PUBLIC METHODS

   serve_static_file $file_path
       Will serve the file located in $file_path statically. This is useful when you need to
       autogenerate them if they don't exist, or they are stored in a model.

           package MyApp::Controller::User;

           sub curr_user_thumb : PathPart("my_thumbnail.png") {
               my ( $self, $c ) = @_;
               my $file_path = $c->user->picture_thumbnail_path;
               $c->serve_static_file($file_path);
           }

INTERNAL EXTENDED METHODS

       Static::Simple extends the following steps in the Catalyst process.

   prepare_action
       "prepare_action" is used to first check if the request path is a static file.  If so, we
       skip all other "prepare_action" steps to improve performance.

   dispatch
       "dispatch" takes the file found during "prepare_action" and writes it to the output.

   finalize
       "finalize" serves up final header information and displays any log messages.

   setup
       "setup" initializes all default values.
