Route to static file in Mojo - perl

Question

I have small app based on mojolicious. And I have index.html in public dir. I want to have route to this file when user asks for '/'.
I wrote two solution, but I don't like them.
First solution - add simple controller.
sub stratup {
//...
$r->get('/')->to('general#index_html');
//...
}
package MyPackage::General;
use Mojo::Base 'Mojolicious::Controller';
use strict;
use warnings;
sub index_html {
my $self = shift;
$self->render_static('index.html');
return;
}
1;
Second solution - add hook
sub startup {
my $self = shift;
$self->hook(before_dispatch => sub {
my $self = shift;
if ($self->req->url eq '/') {
$self->req->url( Mojo::URL->new('/index.html') );
}
});
What I want:
$r->get('/')->to('/index.html');
or something like that.
P.S. I know, than usualy nginx/apache do it, but I use morbo to run code.

Answer 1

You want:
$r->get('...')->to(cb => sub {
my $c = shift;
$c->reply->static('index.html')
});
(As long as you're after Mojolicous 5.45 2014-09-26)

Answer 2

By far the simplest way is
get "/" => "index";

Answer 3

I'll dig this up from the graveyard, why not.
I found myself similarly trying to serve a static html file in a docker container that I had using to serve both a Mojolicious REST API and a Vue.js front end. After searching around and piecing sporadic information together, this is what seems to work for me.
** disclaimer: I have not fully tested this with Vue routing and other aspects as yet.
My directory structure:
/app
/app/script
/app/modules/ui
/app/modules/ui/dist
From the command line the app directory, using morbo to test:
morbo script/ui.pl
ui.pl script
#!/usr/bin/env perl
use Mojolicious::Lite -signatures;
use Mojo::File qw(curfile);
use v5.25;
my $app = app;
my $static = $app->static;
push #{$static->paths}, curfile->dirname->sibling('modules/ui/dist')->to_string;
any '/' => sub {
my $c = shift;
my $content = $static->file("/index.html")->slurp;
$c->render(text => $content);
};
$app->start;
Using a combo of information from https://metacpan.org/pod/Mojolicious::Static and basic routing information at https://docs.mojolicious.org/Mojolicious/Lite, I could get the vue.js index page to render as expected.
** UPDATED A DAY LATER **
As it turns out, there is an easier way, though not clearly documented. If you place the static files inside your public folder, you can use the default helpers included with Mojolicious to render the files. The documentation refers to it here, https://docs.mojolicious.org/Mojolicious/Guides/Rendering#Serving-static-files, but it's not very clear on how to make it happen.
I tooled around some, but it took browsing the code of Controller.pm of for Mojolicious to sort it out. This section of the POD led me to determine how to get the reply object:
=head2 helpers
my $helpers = $c->helpers;
Return a proxy object containing the current controller object and on which helpers provided by /app can be called. This includes all helpers from Mojolicious::Plugin::DefaultHelpers and Mojolicious::Plugin::TagHelpers.
# Make sure to use the "title" helper and not the controller method
$c->helpers->title('Welcome!');
# Use a nested helper instead of the "reply" controller method
$c->helpers->reply->not_found;
Based on this, I can drop my files into the public folder:
/app/public/index.html
Then modify my controller to match:
# https://docs.mojolicious.org/Mojolicious/Guides/Rendering#Serving-static-files
any '/' => sub {
my $c = shift;
$c->helpers->reply->static('index.html');
};
