Pass html file as a route in perl dancer2 MVC framework

Question

I have a file on my machine at /abc/assets/file/

I want to return this file as a route. It is possible to do that ?

Answer 1

You would typically do that outside Dancer in your PSGI file with a different Plack application that's mounted in the same PSGI file. Have a look at Plack::App::File for an individual file, or Plack::App::Directory for an entire directory.

Your PSGI file would then look something like this.

#!/usr/bin/env perl

use strict;
use warnings;
use FindBin;
use lib "$FindBin::Bin/../lib";

use MyApp; # this is Dancer2-based
use Plack::Builder;
use Plack::App::File;
use Plack::App::Directory;

builder {
    mount '/' => MyApp->to_app;
    mount '/abc-file' => Plack::App::File->new(
        file => '/abc/assets/file')->to_app;
    mount '/foo' => Plack::App::Directory->new({ 
        root => "/xyz/foo" })->to_app;
};
