279 Catalyst::Plugin::Static::Simple - Make serving static pages painless.
284 use Catalyst qw/ Static::Simple /;
286 # that's it; static content is automatically served by Catalyst
287 # from the application's root directory, though you can configure
288 # things or bypass Catalyst entirely in a production environment
290 # one caveat: the files must be served from an absolute path
291 # (i.e. /images/foo.png)
295 The Static::Simple plugin is designed to make serving static content in
296 your application during development quick and easy, without requiring a
297 single line of code from you.
299 This plugin detects static files by looking at the file extension in the
300 URL (such as B<.css> or B<.png> or B<.js>). The plugin uses the
301 lightweight L<MIME::Types> module to map file extensions to
302 IANA-registered MIME types, and will serve your static files with the
303 correct MIME type directly to the browser, without being processed
306 Note that actions mapped to paths using periods (.) will still operate
309 If the plugin can not find the file, the request is dispatched to your
310 application instead. This means you are responsible for generating a
311 C<404> error if your applicaton can not process the request:
313 # handled by static::simple, not dispatched to your application
316 # static::simple will not find the file and let your application
317 # handle the request. You are responsible for generating a file
318 # or returning a 404 error
319 /images/does_not_exist.png
321 Though Static::Simple is designed to work out-of-the-box, you can tweak
322 the operation by adding various configuration options. In a production
323 environment, you will probably want to use your webserver to deliver
324 static content; for an example see L<USING WITH APACHE>, below.
326 =head1 DEFAULT BEHAVIOUR
328 By default, Static::Simple will deliver all files having extensions
329 (that is, bits of text following a period (C<.>)), I<except> files
330 having the extensions C<tmpl>, C<tt>, C<tt2>, C<html>, and
331 C<xhtml>. These files, and all files without extensions, will be
332 processed through Catalyst. If L<MIME::Types> doesn't recognize an
333 extension, it will be served as C<text/plain>.
335 To restate: files having the extensions C<tmpl>, C<tt>, C<tt2>, C<html>,
336 and C<xhtml> I<will not> be served statically by default, they will be
337 processed by Catalyst. Thus if you want to use C<.html> files from
338 within a Catalyst app as static files, you need to change the
339 configuration of Static::Simple. Note also that files having any other
340 extension I<will> be served statically, so if you're using any other
341 extension for template files, you should also change the configuration.
343 Logging of static files is turned off by default.
345 =head1 ADVANCED CONFIGURATION
347 Configuration is completely optional and is specified within
348 C<MyApp-E<gt>config-E<gt>{static}>. If you use any of these options,
349 this module will probably feel less "simple" to you!
351 =head2 Enabling request logging
353 Since Catalyst 5.50, logging of static requests is turned off by
354 default; static requests tend to clutter the log output and rarely
355 reveal anything useful. However, if you want to enable logging of static
356 requests, you can do so by setting
357 C<MyApp-E<gt>config-E<gt>{static}-E<gt>{logging}> to 1.
359 =head2 Forcing directories into static mode
361 Define a list of top-level directories beneath your 'root' directory
362 that should always be served in static mode. Regular expressions may be
363 specified using C<qr//>.
374 =head2 Including additional directories
376 You may specify a list of directories in which to search for your static
377 files. The directories will be searched in order and will return the
378 first file found. Note that your root directory is B<not> automatically
379 added to the search path when you specify an C<include_path>. You should
380 use C<MyApp-E<gt>config-E<gt>{root}> to add it.
387 MyApp->config->{root},
392 With the above setting, a request for the file C</images/logo.jpg> will search
393 for the following files, returning the first one found:
395 /path/to/overlay/images/logo.jpg
396 /dynamic/path/images/logo.jpg
397 /your/app/home/root/images/logo.jpg
399 The include path can contain a subroutine reference to dynamically return a
400 list of available directories. This method will receive the C<$c> object as a
401 parameter and should return a reference to a list of directories. Errors can
402 be reported using C<die()>. This method will be called every time a file is
403 requested that appears to be a static file (i.e. it has an extension).
407 sub incpath_generator {
410 if ( $c->session->{customer_dir} ) {
411 return [ $c->session->{customer_dir} ];
413 die "No customer dir defined.";
417 =head2 Ignoring certain types of files
419 There are some file types you may not wish to serve as static files.
420 Most important in this category are your raw template files. By
421 default, files with the extensions C<tmpl>, C<tt>, C<tt2>, C<html>, and
422 C<xhtml> will be ignored by Static::Simple in the interest of security.
423 If you wish to define your own extensions to ignore, use the
424 C<ignore_extensions> option:
428 ignore_extensions => [ qw/html asp php/ ],
432 =head2 Ignoring entire directories
434 To prevent an entire directory from being served statically, you can use
435 the C<ignore_dirs> option. This option contains a list of relative
436 directory paths to ignore. If using C<include_path>, the path will be
437 checked against every included path.
441 ignore_dirs => [ qw/tmpl css/ ],
445 For example, if combined with the above C<include_path> setting, this
446 C<ignore_dirs> value will ignore the following directories if they exist:
448 /path/to/overlay/tmpl
452 /your/app/home/root/tmpl
453 /your/app/home/root/css
455 =head2 Custom MIME types
457 To override or add to the default MIME types set by the L<MIME::Types>
458 module, you may enter your own extension to MIME type mapping.
469 =head2 Controlling caching with Expires header
471 The files served by Static::Simple will have a Last-Modified header set,
472 which allows some browsers to cache them for a while. However if you want
473 to explicitly set an Expires header, such as to allow proxies to cache your
474 static content, then you can do so by setting the "expires" config option.
476 The value indicates the number of seconds after access time to allow caching.
477 So a value of zero really means "don't cache at all", and any higher values
478 will keep the file around for that long.
482 expires => 3600, # Caching allowed for one hour.
486 =head2 Compatibility with other plugins
488 Since version 0.12, Static::Simple plays nice with other plugins. It no
489 longer short-circuits the C<prepare_action> stage as it was causing too
490 many compatibility issues with other plugins.
492 =head2 Debugging information
494 Enable additional debugging information printed in the Catalyst log. This
495 is automatically enabled when running Catalyst in -Debug mode.
503 =head1 USING WITH APACHE
505 While Static::Simple will work just fine serving files through Catalyst
506 in mod_perl, for increased performance you may wish to have Apache
507 handle the serving of your static files directly. To do this, simply use
508 a dedicated directory for your static files and configure an Apache
509 Location block for that directory This approach is recommended for
510 production installations.
512 <Location /myapp/static>
513 SetHandler default-handler
516 Using this approach Apache will bypass any handling of these directories
517 through Catalyst. You can leave Static::Simple as part of your
518 application, and it will continue to function on a development server,
519 or using Catalyst's built-in server.
521 In practice, your Catalyst application is probably (i.e. should be)
522 structured in the recommended way (i.e., that generated by bootstrapping
523 the application with the C<catalyst.pl> script, with a main directory
524 under which is a C<lib/> directory for module files and a C<root/>
525 directory for templates and static files). Thus, unless you break up
526 this structure when deploying your app by moving the static files to a
527 different location in your filesystem, you will need to use an Alias
528 directive in Apache to point to the right place. You will then need to
529 add a Directory block to give permission for Apache to serve these
530 files. The final configuration will look something like this:
532 Alias /myapp/static /filesystem/path/to/MyApp/root/static
533 <Directory /filesystem/path/to/MyApp/root/static>
536 <Location /myapp/static>
537 SetHandler default-handler
540 If you are running in a VirtualHost, you can just set the DocumentRoot
541 location to the location of your root directory; see
542 L<Catalyst::Engine::Apache2::MP20>.
544 =head1 PUBLIC METHODS
546 =head2 serve_static_file $file_path
548 Will serve the file located in $file_path statically. This is useful when
549 you need to autogenerate them if they don't exist, or they are stored in a model.
551 package MyApp::Controller::User;
553 sub curr_user_thumb : PathPart("my_thumbnail.png") {
554 my ( $self, $c ) = @_;
555 my $file_path = $c->user->picture_thumbnail_path;
556 $c->serve_static_file($file_path);
559 =head1 INTERNAL EXTENDED METHODS
561 Static::Simple extends the following steps in the Catalyst process.
563 =head2 prepare_action
565 C<prepare_action> is used to first check if the request path is a static
566 file. If so, we skip all other C<prepare_action> steps to improve
571 C<dispatch> takes the file found during C<prepare_action> and writes it
576 C<finalize> serves up final header information and displays any log
581 C<setup> initializes all default values.
