Now, the C<config> attribute of C<$self> will be set to a HashRef
containing keys 'title' and 'posts_dir'.
-If you construct your application like:
+The keys from default_config are merged into any config supplied, so
+if you construct your application like:
- MyWebSimpleApp::Web->new(config=>{environment=>'dev'})
+ MyWebSimpleApp::Web->new(
+ config => { title => 'Spoon', environment => 'dev' }
+ )
-then C<config> will have a C<environment> key with a value of 'dev'.
+then C<config> will contain:
-=head2 run_if_script
-
-In the case where you wish to run your L<Web::Simple> based application as a
-stand alone CGI application, you can simple do:
+ {
+ title => 'Spoon',
+ posts_dir => '/path/to/myapp/posts',
+ environment => 'dev'
+ }
- ## my_web_simple_app.pl
- use MyWebSimpleApp::Web;
- MyWebSimpleApp::Web->run_if_script.
+=head2 run_if_script
-Or (even more simply) just inline the entire application:
+The run_if_script method is designed to be used at the end of the script
+or .pm file where your application class is defined - for example:
## my_web_simple_app.pl
#!/usr/bin/env perl
HelloWorld->run_if_script;
-Additionally, you can treat the above script as though it were a standard PSGI
-application file (*.psgi). For example you can start up up with C<plackup>
+This returns a true value, so your file is now valid as a module - so
- plackup my_web_simple_app.pl
+ require 'my_web_simple_app.pl';
-Which means you can write a L<Web::Simple> application as a plain old CGI
-application and seemlessly migrate to a L<Plack> based solution when you are
-ready for that.
+ my $hw = HelloWorld->new;
-Lastly, L</run_if_script> will automatically detect and support a Fast CGI
-environment.
+will work fine (and you can rename it to lib/HelloWorld.pm later to make it
+a real use-able module).
-=head2 to_psgi_app
+However, it detects if it's being run as a script (via testing $0) and if
+so attempts to do the right thing.
-Given a L<Web::Simple> application root namespace, return it in a form suitable
-to run in inside a L<Plack> container, or in L<Plack::Builder> or in a C<*.psgi>
-file:
+If run under a CGI environment, your application will execute as a CGI.
- ## app.psgi
- use strictures 1;
- use Plack::Builder;
- use MyWebSimpleApp::Web;
+If run under a FastCGI environment, your application will execute as a
+FastCGI process (this works both for dynamic shared-hosting-style FastCGI
+and for apache FastCgiServer style setups).
- builder {
- ## enable middleware
- enable 'StackTrace';
- enable 'Debug';
+If run from the commandline with a URL path, it runs a GET request against
+that path -
- ## return application
- MyWebSimpleApp::Web->to_psgi_app;
- };
+ $ perl -Ilib examples/hello-world/hello-world.cgi /
+ 200 OK
+ Content-Type: text/plain
+
+ Hello world!
+
+Additionally, you can treat the file as though it were a standard PSGI
+application file (*.psgi). For example you can start up up with C<plackup>
+
+ plackup my_web_simple_app.pl
+
+or C<starman>
-This could be run via C<plackup>, etc. Please note the L<Plack::Builder> DSL
-is optional, if you are enabling L<Plack::Middleware> internally in your
-L<Web::Simple> application; your app.psgi could be as simple as:
+ starman my_web_simple_app.pl
- use MyWebSimpleApp::Web;
- MyWebSimpleApp::Web->to_psgi_app;
+=head2 to_psgi_app
-This means if you want to provide a 'default' set of middleware, one option is
-to modify this method:
+This method is called by L</run_if_script> to create the L<PSGI> app coderef
+for use via L<Plack> and L<plackup>. If you want to globally add middleware,
+you can override this method:
use Web::Simple 'HelloWorld';
use Plack::Builder;
};
}
-As always, mix and match the pieces you actually need and remember the
-L<Web::Simple> philosophy of trying to keep it as minimal and simple as possible.
+This method can also be used to mount a Web::Simple application within
+a separate C<*.psgi> file -
+
+ use strictures 1;
+ use Plack::Builder;
+ use WSApp;
+ use AnotherWSApp;
+
+ builder {
+ mount '/' => WSApp->to_psgi_app;
+ mount '/another' => AnotherWSApp->to_psgi_app;
+ };
+
+This method can be called as a class method, in which case it implicitly
+calls ->new, or as an object method ... in which case it doesn't.
