NAME

Mojolicious::Plugin::MountPSGI - Mount PSGI apps

SYNOPSIS

  # Mojolicious
  $self->plugin('MountPSGI', { '/' => 'ext/MyApp/app.psgi'});

  # Mojolicious::Lite
  plugin 'MountPSGI', { '/' => 'ext/MyApp/app.psgi' };

  # rewrite the path so the psgi app doesn't see the mount point
  # thus app.psgi sees / when /mount is visited
  plugin 'MountPSGI', { '/mount' => 'ext/MyApp/app.psgi', rewrite => 1 };

DESCRIPTION

Mojolicious::Plugin::MountPSGI lets you mount any PSGI app inside a Mojolicious app. For instance you could use this to deploy your PSGI app under hypnotoad, or to include a PSGI app inside a path inside your Mojo app.

The key given is the route under which to mount the app. The value is either a PSGI application or a string which resolves to an instance via "load_psgi" in Plack::Util.

One additional option is rewrite which if set to a true value will rewrite the PATH_INFO and SCRIPT_NAME values in the env hash so that the application does not see the mount point in its request path. This uses the mechanism as described by Plack::App::URLMap.

CAVEATS

Due to the way Mojolicious parses multipart requests, the original request body is not available to pass to the PSGI application. As a stopgap measure this plugin rebuilds the request from its parts at what is likely a huge cost in performance. There has been discussion about "adding proxying primatives" to Mojolicious which would likely be useful in resolving this performance hit.

If PLACK_ENV is not otherwise set, the "mode" in Mojolicious will be used while loading the application script and during synchronous responses. For delayed responses, the plugin cannot ensure that it will be set. Applications should fetch their PLACK_ENV before requesting a delayed response and manage it appropriately.

METHODS

Mojolicious::Plugin::MountPSGI inherits all methods from Mojolicious::Plugin and implements the following new ones.
