=head1 NAME

App::Filite::Client - client library for Filite servers

=head1 SYNOPSIS

  my $client = App::Filite::Client->new_from_config;
  my $url = $client->share( 'path/to/file.txt' );
  print "Shared to $url\n";

=head1 DESCRIPTION

Share a file, chunk of text, or link via a Filite server.

Filite is a URL shortner, file sharer, and pastebin that you can self-host.

=head2 Config File

Configuration is via a JSON-formatted file usually named
F<< ~/.config/filite-client/config.json >> (see also L<File::XDG>),
though this can be overridden using the C<< FILITE_CLIENT_CONFIG >>
environment variable.

=head2 Constructors

=over

=item C<< new( %attrs ) >>

Moose-like constructor.

=item C<< new_from_config() >>

Load C<< %attrs >> from the config instead of as parameters.

=back

=head2 Attributes

All attributes are read-write.

=over

=item C<< server >> B<< Str >>

The filite server to share things via. This will typically be a URL
like "https://example.com/" or "http://example.net:8080".
