# Mojo::Server::Morbo::Backend(3pm)

Morbo backend base class

## NAME

Mojo::Server::Morbo::Backend - Morbo backend base class

## SYNOPSIS

```
  package Mojo::Server::Morbo::Backend::Inotify:
  use Mojo::Base 'Mojo::Server::Morbo::Backend';
  sub modified_files {...}
```

## DESCRIPTION

Mojo::Server::Morbo::Backend is an abstract base class for Morbo backends, like Mojo::Server::Morbo::Backend::Poll.

## ATTRIBUTES

Mojo::Server::Morbo::Backend implements the following attributes.

### watch

```
  my $watch = $backend->watch;
  $backend  = $backend->watch(['/home/sri/my_app']);
```

Files and directories to watch for changes, defaults to the application script as well as the `"lib"` and `"templates"` directories in the current working directory.

### watch\_timeout

```
  my $timeout = $backend->watch_timeout;
  $backend    = $backend->watch_timeout(10);
```

Maximum amount of time in seconds a backend may block when waiting for files to change, defaults to the value of the `"MOJO_MORBO_TIMEOUT"` environment variable or `1`.

## METHODS

Mojo::Server::Morbo::Backend inherits all methods from Mojo::Base and implements the following new ones.

### modified\_files

```
  my $files = $backend->modified_files;
```

Check if files from "watch" have been modified since the last check and return an array reference with the results. Meant to be overloaded in a subclass.

```
  # All files that have been modified
  say for @{$backend->modified_files};
```
