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

9 use Catalyst;
10 MyApp->setup( qw/Static::Simple/ );
11 # that's it; static content is automatically served by Catalyst
12 # from the application's root directory, though you can configure
13 # things or bypass Catalyst entirely in a production environment
14 #
15 # one caveat: the files must be served from an absolute path
16 # (ie. /images/foo.png)
17
19 The Static::Simple plugin is designed to make serving static content in
20 your application during development quick and easy, without requiring a
21 single line of code from you.
22
23 This plugin detects static files by looking at the file extension in
24 the URL (such as .css or .png or .js). The plugin uses the lightweight
25 MIME::Types module to map file extensions to IANA-registered MIME
26 types, and will serve your static files with the correct MIME type
27 directly to the browser, without being processed through Catalyst.
28
29 Note that actions mapped to paths using periods (.) will still operate
30 properly.
31
32 Though Static::Simple is designed to work out-of-the-box, you can tweak
33 the operation by adding various configuration options. In a production
34 environment, you will probably want to use your webserver to deliver
35 static content; for an example see "USING WITH APACHE", below.
36
38 By default, Static::Simple will deliver all files having extensions
39 (that is, bits of text following a period (".")), except files having
40 the extensions "tmpl", "tt", "tt2", "html", and "xhtml". These files,
41 and all files without extensions, will be processed through Catalyst.
42 If MIME::Types doesn't recognize an extension, it will be served as
43 "text/plain".
44
45 To restate: files having the extensions "tmpl", "tt", "tt2", "html",
46 and "xhtml" will not be served statically by default, they will be pro‐
47 cessed by Catalyst. Thus if you want to use ".html" files from within a
48 Catalyst app as static files, you need to change the configuration of
49 Static::Simple. Note also that files having any other extension will be
50 served statically, so if you're using any other extension for template
51 files, you should also change the configuration.
52
53 Logging of static files is turned off by default.
54
56 Configuration is completely optional and is specified within
57 "MyApp->config->{static}". If you use any of these options, this mod‐
58 ule will probably feel less "simple" to you!
59
60 Enabling request logging
61
62 Since Catalyst 5.50, logging of static requests is turned off by
63 default; static requests tend to clutter the log output and rarely
64 reveal anything useful. However, if you want to enable logging of
65 static requests, you can do so by setting "MyApp->con‐
66 fig->{static}->{logging}" to 1.
67
68 Forcing directories into static mode
69
70 Define a list of top-level directories beneath your 'root' directory
71 that should always be served in static mode. Regular expressions may
72 be specified using "qr//".
73
74 MyApp->config->{static}->{dirs} = [
75 'static',
76 qr/^(images⎪css)/,
77 ];
78
79 Including additional directories
80
81 You may specify a list of directories in which to search for your
82 static files. The directories will be searched in order and will return
83 the first file found. Note that your root directory is not automati‐
84 cally added to the search path when you specify an "include_path". You
85 should use "MyApp->config->{root}" to add it.
86
87 MyApp->config->{static}->{include_path} = [
88 '/path/to/overlay',
89 \&incpath_generator,
90 MyApp->config->{root}
91 ];
92
93 With the above setting, a request for the file "/images/logo.jpg" will
94 search for the following files, returning the first one found:
95
96 /path/to/overlay/images/logo.jpg
97 /dynamic/path/images/logo.jpg
98 /your/app/home/root/images/logo.jpg
99
100 The include path can contain a subroutine reference to dynamically
101 return a list of available directories. This method will receive the
102 $c object as a parameter and should return a reference to a list of
103 directories. Errors can be reported using "die()". This method will
104 be called every time a file is requested that appears to be a static
105 file (i.e. it has an extension).
106
107 For example:
108
109 sub incpath_generator {
110 my $c = shift;
111
112 if ( $c->session->{customer_dir} ) {
113 return [ $c->session->{customer_dir} ];
114 } else {
115 die "No customer dir defined.";
116 }
117 }
118
119 Ignoring certain types of files
120
121 There are some file types you may not wish to serve as static files.
122 Most important in this category are your raw template files. By
123 default, files with the extensions "tmpl", "tt", "tt2", "html", and
124 "xhtml" will be ignored by Static::Simple in the interest of security.
125 If you wish to define your own extensions to ignore, use the
126 "ignore_extensions" option:
127
128 MyApp->config->{static}->{ignore_extensions}
129 = [ qw/html asp php/ ];
130
131 Ignoring entire directories
132
133 To prevent an entire directory from being served statically, you can
134 use the "ignore_dirs" option. This option contains a list of relative
135 directory paths to ignore. If using "include_path", the path will be
136 checked against every included path.
137
138 MyApp->config->{static}->{ignore_dirs} = [ qw/tmpl css/ ];
139
140 For example, if combined with the above "include_path" setting, this
141 "ignore_dirs" value will ignore the following directories if they
142 exist:
143
144 /path/to/overlay/tmpl
145 /path/to/overlay/css
146 /dynamic/path/tmpl
147 /dynamic/path/css
148 /your/app/home/root/tmpl
149 /your/app/home/root/css
150
151 Custom MIME types
152
153 To override or add to the default MIME types set by the MIME::Types
154 module, you may enter your own extension to MIME type mapping.
155
156 MyApp->config->{static}->{mime_types} = {
157 jpg => 'image/jpg',
158 png => 'image/png',
159 };
160
161 Compatibility with other plugins
162
163 Since version 0.12, Static::Simple plays nice with other plugins. It
164 no longer short-circuits the "prepare_action" stage as it was causing
165 too many compatibility issues with other plugins.
166
167 Debugging information
168
169 Enable additional debugging information printed in the Catalyst log.
170 This is automatically enabled when running Catalyst in -Debug mode.
171
172 MyApp->config->{static}->{debug} = 1;
173
175 While Static::Simple will work just fine serving files through Catalyst
176 in mod_perl, for increased performance, you may wish to have Apache
177 handle the serving of your static files. To do this, simply use a ded‐
178 icated directory for your static files and configure an Apache Location
179 block for that directory. This approach is recommended for production
180 installations.
181
182 <Location /static>
183 SetHandler default-handler
184 </Location>
185
186 Using this approach Apache will bypass any handling of these directo‐
187 ries through Catalyst. You can leave Static::Simple as part of your
188 application, and it will continue to function on a development server,
189 or using Catalyst's built-in server.
190
192 serve_static_file $file_path
193
194 Will serve the file located in $file_path statically. This is useful
195 when you need to autogenerate them if they don't exist, or they are
196 stored in a model.
197
198 package MyApp::Controller::User;
199
200 sub curr_user_thumb : PathPart("my_thumbnail.png") {
201 my ( $self, $c ) = @_;
202 my $file_path = $c->user->picture_thumbnail_path;
203 $c->serve_static_file($file_path);
204 }
205
207 Static::Simple extends the following steps in the Catalyst process.
208
209 prepare_action
210
211 "prepare_action" is used to first check if the request path is a static
212 file. If so, we skip all other "prepare_action" steps to improve per‐
213 formance.
214
215 dispatch
216
217 "dispatch" takes the file found during "prepare_action" and writes it
218 to the output.
219
220 finalize
221
222 "finalize" serves up final header information and displays any log mes‐
223 sages.
224
225 setup
226
227 "setup" initializes all default values.
