NAME ^

Plack::Middleware::Static - serve static files with Plack

SYNOPSIS ^

  use Plack::Builder;

  builder {
      enable "Plack::Middleware::Static",
          path => qr{^/(images|js|css)/}, root => './htdocs/';
      $app;
  };

DESCRIPTION ^

Enable this middleware to allow your Plack-based application to serve static files. If a static file exists for the requested path, it will be served. Otherwise, the request will be passed on to the application for further processing.

If the requested document is not within the root (i.e. directory traversal) or the file is there but not readable, this middleware will return a 403 Forbidden response.

The content type returned will be determined from the file extension based on Plack::MIME.

CONFIGURATIONS ^

path, root
  enable "Plack::Middleware::Static",
      path => qr{^/static/}, root => 'htdocs/';

path specifies the URL pattern (regular expression) or a callback to match with requests to serve static files for. root specifies the root directory to serve those static files from. The default value of root is the current directory.

This examples configuration serves /static/foo.jpg from htdocs/static/foo.jpg. Note that the matched /static/ portion is still appears in the local mapped path. If you don't like it, use a callback instead to munge $_:

  enable "Plack::Middleware::Static",
      path => sub { s!^/static/!! }, root => 'static-files/';

This configuration would serve /static/foo.png from static-files/foo.png (not static-files/static/foo.png). The callback specified in path option matches against $_ and then updates the value since it does s///, and returns the number of matches, so it will pass through when /static/ doesn't match.

If you want to map multiple static directories from different root, simply add "this", middleware multiple times with different configuration options.
