Thanks for the suggestion MyLib.pm is 
package MyLib;
use Mojo::Base 'Mojolicious';
use Mojo::mysql;
#my %connections;

# This method will run once at server start
sub startup {
    my $self = shift;

    # Router
    my $r = $self->routes;

    # Normal route to controller
    $r->get('/')->to( template => 'index' );
    $r->get('/libmap');    #->to(controller => 'libmap');
    $r->get('/invtot')->to(
        controller => 'invtot',
        title      => 'Paper journals from the library',
        cb         => sub { $self->connect_invtot() }
    );

    if ( exists $ENV{PAR_TEMP} && $^O eq "MSWin32" ) {
        system qw(start http://localhost:3000/invtot);
    }

    $r->post('/invtot')->to( controller => 'Invtot', action => 'post' 
+);

}

sub connect_invtot {

    my $self = shift;
    #return if $connections{db1};

    # Load configuration from hash returned by config file
    my $file;
    if ( $ENV{PAR_TEMP} ) {
        print $ENV{PAR_TEMP}, "\n";
        $file = $ENV{PAR_TEMP} . "/inc/script/my_lib.conf";
    }
    else {
        $file = 'my_lib.conf';
    }
    my $config = $self->plugin( 'Config', { file => $file } );

    # Configure the application
    $self->secrets( $config->{secrets} );

    $self->log->debug("connecting...");
    
    $self->helper(db1 => sub {state $db1 = Mojo::mysql->strict_mode('m
+ysql://'.  $config->{username} . ':'. $config->{password} . '@my.../d
+okpe_i01'  )});
    $self->db1->options({
                'pg_enable_utf8' => 1,
                AutoCommit       => 1,
                PrintError       => 0,

            });

In my Invtot.pm controller the post method is 
sub post {
  my $c = shift;
#get data from the form and build sql in $sql{$key}
        my $stm = $c->app->db1->db->prepare_cached( $sql{$key} )
            or die $c->app->db1->db->errstr;    # unless(exists $sql{$
+key});
        $toFind = format_search_arg( $toFind, $mode );
        $c->app->log->debug( $mode . " " . $toFind );
        $stm->execute($toFind) or die $stm->errstr;
        $c->stash( stm => $stm, for_abo => $for_abo );

}
