244 Catalyst::Plugin::Static::Simple - Make serving static pages painless.
249 MyApp->setup( qw/Static::Simple/ );
250 # that's it; static content is automatically served by
251 # Catalyst, though you can configure things or bypass
252 # Catalyst entirely in a production environment
256 The Static::Simple plugin is designed to make serving static content in
257 your application during development quick and easy, without requiring a
258 single line of code from you.
260 This plugin detects static files by looking at the file extension in the
261 URL (such as B<.css> or B<.png> or B<.js>). The plugin uses the
262 lightweight L<MIME::Types> module to map file extensions to
263 IANA-registered MIME types, and will serve your static files with the
264 correct MIME type directly to the browser, without being processed
267 Note that actions mapped to paths using periods (.) will still operate
270 Though Static::Simple is designed to work out-of-the-box, you can tweak
271 the operation by adding various configuration options. In a production
272 environment, you will probably want to use your webserver to deliver
273 static content; for an example see L<USING WITH APACHE>, below.
275 =head1 DEFAULT BEHAVIOR
277 By default, Static::Simple will deliver all files having extensions
278 (that is, bits of text following a period (C<.>)), I<except> files
279 having the extensions C<tmpl>, C<tt>, C<tt2>, C<html>, and
280 C<xhtml>. These files, and all files without extensions, will be
281 processed through Catalyst. If L<MIME::Types> doesn't recognize an
282 extension, it will be served as C<text/plain>.
284 To restate: files having the extensions C<tmpl>, C<tt>, C<tt2>, C<html>,
285 and C<xhtml> I<will not> be served statically by default, they will be
286 processed by Catalyst. Thus if you want to use C<.html> files from
287 within a Catalyst app as static files, you need to change the
288 configuration of Static::Simple. Note also that files having any other
289 extension I<will> be served statically, so if you're using any other
290 extension for template files, you should also change the configuration.
292 Logging of static files is turned off by default.
294 =head1 ADVANCED CONFIGURATION
296 Configuration is completely optional and is specified within
297 C<MyApp-E<gt>config-E<gt>{static}>. If you use any of these options,
298 this module will probably feel less "simple" to you!
300 =head2 Enabling request logging
302 Since Catalyst 5.50, logging of static requests is turned off by
303 default; static requests tend to clutter the log output and rarely
304 reveal anything useful. However, if you want to enable logging of static
305 requests, you can do so by setting
306 C<MyApp-E<gt>config-E<gt>{static}-E<gt>{no_logs}> to 0.
308 =head2 Forcing directories into static mode
310 Define a list of top-level directories beneath your 'root' directory
311 that should always be served in static mode. Regular expressions may be
312 specified using C<qr//>.
314 MyApp->config->{static}->{dirs} = [
319 =head2 Including additional directories
321 You may specify a list of directories in which to search for your static
322 files. The directories will be searched in order and will return the
323 first file found. Note that your root directory is B<not> automatically
324 added to the search path when you specify an C<include_path>. You should
325 use C<MyApp-E<gt>config-E<gt>{root}> to add it.
327 MyApp->config->{static}->{include_path} = [
330 MyApp->config->{root}
333 With the above setting, a request for the file C</images/logo.jpg> will search
334 for the following files, returning the first one found:
336 /path/to/overlay/images/logo.jpg
337 /dynamic/path/images/logo.jpg
338 /your/app/home/root/images/logo.jpg
340 The include path can contain a subroutine reference to dynamically return a
341 list of available directories. This method will receive the C<$c> object as a
342 parameter and should return a reference to a list of directories. Errors can
343 be reported using C<die()>. This method will be called every time a file is
344 requested that appears to be a static file (i.e. it has an extension).
348 sub incpath_generator {
351 if ( $c->session->{customer_dir} ) {
352 return [ $c->session->{customer_dir} ];
354 die "No customer dir defined.";
358 =head2 Ignoring certain types of files
360 There are some file types you may not wish to serve as static files.
361 Most important in this category are your raw template files. By
362 default, files with the extensions C<tmpl>, C<tt>, C<tt2>, C<html>, and
363 C<xhtml> will be ignored by Static::Simple in the interest of security.
364 If you wish to define your own extensions to ignore, use the
365 C<ignore_extensions> option:
367 MyApp->config->{static}->{ignore_extensions}
368 = [ qw/html asp php/ ];
370 =head2 Ignoring entire directories
372 To prevent an entire directory from being served statically, you can use
373 the C<ignore_dirs> option. This option contains a list of relative
374 directory paths to ignore. If using C<include_path>, the path will be
375 checked against every included path.
377 MyApp->config->{static}->{ignore_dirs} = [ qw/tmpl css/ ];
379 For example, if combined with the above C<include_path> setting, this
380 C<ignore_dirs> value will ignore the following directories if they exist:
382 /path/to/overlay/tmpl
386 /your/app/home/root/tmpl
387 /your/app/home/root/css
389 =head2 Custom MIME types
391 To override or add to the default MIME types set by the L<MIME::Types>
392 module, you may enter your own extension to MIME type mapping.
394 MyApp->config->{static}->{mime_types} = {
399 =head2 Compatibility with other plugins
401 Since version 0.12, Static::Simple plays nice with other plugins. It no
402 longer short-circuits the C<prepare_action> stage as it was causing too
403 many compatibility issues with other plugins.
405 =head2 Debugging information
407 Enable additional debugging information printed in the Catalyst log. This
408 is automatically enabled when running Catalyst in -Debug mode.
410 MyApp->config->{static}->{debug} = 1;
412 =head1 USING WITH APACHE
414 While Static::Simple will work just fine serving files through Catalyst in
415 mod_perl, for increased performance, you may wish to have Apache handle the
416 serving of your static files. To do this, simply use a dedicated directory
417 for your static files and configure an Apache Location block for that
418 directory. This approach is recommended for production installations.
421 SetHandler default-handler
424 Using this approach Apache will bypass any handling of these directories
425 through Catalyst. You can leave Static::Simple as part of your
426 application, and it will continue to function on a development server,
427 or using Catalyst's built-in server.
429 =head1 INTERNAL EXTENDED METHODS
431 Static::Simple extends the following steps in the Catalyst process.
433 =head2 prepare_action
435 C<prepare_action> is used to first check if the request path is a static
436 file. If so, we skip all other C<prepare_action> steps to improve
441 C<dispatch> takes the file found during C<prepare_action> and writes it
446 C<finalize> serves up final header information and displays any log
451 C<setup> initializes all default values.
