Mojolicious::Plugin::ServerSession - Perl extension to enable an additional server side session in mojolicious


  #Basic example
  $self->plugin('ServerSession' => {
    key => "server_session_key",
    load => sub { 
      my ($c, $key) = @_;

      my $session_object = MySessionDataStore->find_or_create_by_key($key);

      return( $session_object->key, $session_object->session_hash_ref );
    store => sub { 
      my ($c, $key, $session_hash) = @_;

      my $session_object = MySessionDataStore->find_by_key($key);

  #Then to use in controller or views
  $c->server_session->{Some_key} = "Value"; #Note: Its just a hash ref for simplicity 

  #Real world example using DBIx::Class
  $app->plugin('ServerSession' => {
    key => "server_session_key",
    load => sub { 
      my ($c, $key) = @_;
      my $session_row;
      use JSON;

      unless($session_row = $c->app->schema->resultset('Session')->find($key)) {
        $session_row = $c->app->schema->resultset('Session')->new({ content => "{}" })->insert();
        $key = $session_row->id();

      return( $key, decode_json($session_row->content));
    store => sub { 
      my ($c, $key, $session_hash) = @_;
      use JSON;

      my $session = $c->app->schema->resultset('Session')->find($key);
      if($session) {
        $session->content( encode_json($session_hash) );


This is a little plugin to add an additional session store to your mojolicious app. Useful if you need to store more data than the cookie size of 4096 bytes will allow.

The existing mojo session is not touched, other than to add a key which is used to lookup data in your server side store.

You need to define two subrefs, one for loading and one for storing. The loading subref is expected to return two values, an ID and a hashref containing the server side session data. If the user is new the $key passed in will be undef.

In the DBIx::Class example I either find or create a row in the Session table when &load is called, and I also use JSON to serialise the hash. In the store I simply look up the row, and set its contents to a JSON encoded string.



SEE ALSO ^ does similar but tries to co-operate with the built in sessions.
