248 Catalyst::Plugin::Static::Simple - Make serving static pages painless.
253 MyApp->setup( qw/Static::Simple/ );
257 The Static::Simple plugin is designed to make serving static content in your
258 application during development quick and easy, without requiring a single
259 line of code from you.
261 It will detect static files used in your application by looking for file
262 extensions in the URI. By default, you can simply load this plugin and it
263 will immediately begin serving your static files with the correct MIME type.
264 The light-weight MIME::Types module is used to map file extensions to
265 IANA-registered MIME types.
267 Note that actions mapped to paths using periods (.) will still operate
270 You may further tweak the operation by adding configuration options, described
273 =head1 ADVANCED CONFIGURATION
275 Configuration is completely optional and is specified within
276 MyApp->config->{static}. If you use any of these options, the module will
277 probably feel less "simple" to you!
279 =head2 Aborting request logging
281 Since Catalyst 5.50, there has been added support for dropping logging for a
282 request. This is enabled by default for static files, as static requests tend
283 to clutter the log output. However, if you want logging of static requests,
284 you can enable it by setting MyApp->config->{static}->{no_logs} to 0.
286 =head2 Forcing directories into static mode
288 Define a list of top-level directories beneath your 'root' directory that
289 should always be served in static mode. Regular expressions may be
290 specified using qr//.
292 MyApp->config->{static}->{dirs} = [
297 =head2 Including additional directories
299 You may specify a list of directories in which to search for your static
300 files. The directories will be searched in order and will return the first
301 file found. Note that your root directory is B<not> automatically added to
302 the search path when you specify an include_path. You should use
303 MyApp->config->{root} to add it.
305 MyApp->config->{static}->{include_path} = [
308 MyApp->config->{root}
311 With the above setting, a request for the file /images/logo.jpg will search
312 for the following files, returning the first one found:
314 /path/to/overlay/images/logo.jpg
315 /dynamic/path/images/logo.jpg
316 /your/app/home/root/images/logo.jpg
318 The include path can contain a subroutine reference to dynamically return a
319 list of available directories. This method will receive the $c object as a
320 parameter and should return a reference to a list of directories. Errors can
321 be reported using die(). This method will be called every time a file is
322 requested that appears to be a static file (i.e. it has an extension).
326 sub incpath_generator {
329 if ( $c->session->{customer_dir} ) {
330 return [ $c->session->{customer_dir} ];
332 die "No customer dir defined.";
336 =head2 Ignoring certain types of files
338 There are some file types you may not wish to serve as static files. Most
339 important in this category are your raw template files. By default, files
340 with the extensions tt, tt2, html, and xhtml will be ignored by Static::Simple
341 in the interest of security. If you wish to define your own extensions to
342 ignore, use the ignore_extensions option:
344 MyApp->config->{static}->{ignore_extensions} = [ qw/tt tt2 html xhtml/ ];
346 =head2 Ignoring entire directories
348 To prevent an entire directory from being served statically, you can use the
349 ignore_dirs option. This option contains a list of relative directory paths
350 to ignore. If using include_path, the path will be checked against every
353 MyApp->config->{static}->{ignore_dirs} = [ qw/tmpl css/ ];
355 For example, if combined with the above include_path setting, this
356 ignore_dirs value will ignore the following directories if they exist:
358 /path/to/overlay/tmpl
362 /your/app/home/root/tmpl
363 /your/app/home/root/css
365 =head2 Custom MIME types
367 To override or add to the default MIME types set by the MIME::Types module,
368 you may enter your own extension to MIME type mapping.
370 MyApp->config->{static}->{mime_types} = {
375 =head2 Bypassing other plugins
377 This plugin checks for a static file in the prepare_action stage. If the
378 request is for a static file, it will bypass all remaining prepare_action
379 steps. This means that by placing Static::Simple before all other plugins,
380 they will not execute when a static file is found. This can be helpful by
381 skipping session cookie checks for example. Or, if you want some plugins
382 to run even on static files, list them before Static::Simple.
384 Currently, work done by plugins in any other prepare method will execute
387 =head2 Debugging information
389 Enable additional debugging information printed in the Catalyst log. This
390 is automatically enabled when running Catalyst in -Debug mode.
392 MyApp->config->{static}->{debug} = 1;
394 =head1 USING WITH APACHE
396 While Static::Simple will work just fine serving files through Catalyst in
397 mod_perl, for increased performance, you may wish to have Apache handle the
398 serving of your static files. To do this, simply use a dedicated directory
399 for your static files and configure an Apache Location block for that
400 directory. This approach is recommended for production installations.
403 SetHandler default-handler
406 =head1 INTERNAL EXTENDED METHODS
408 Static::Simple extends the following steps in the Catalyst process.
410 =head2 prepare_action
412 prepare_action is used to first check if the request path is a static file.
413 If so, we skip all other prepare_action steps to improve performance.
417 dispatch takes the file found during prepare_action and writes it to the
422 finalize serves up final header information and displays any log messages.
426 setup initializes all default values.
