  $file->add_chunk('foo bar baz');
  say 'File contains "bar"' if $file->contains('bar') >= 0;
  say $file->slurp;

  # Existing file
  my $file = Mojo::Asset::File->new(path => '/home/sri/foo.txt');

DESCRIPTION

Mojo::Asset::File is a file storage backend for HTTP content.

EVENTS

cleanup

  my $bool = $file->cleanup;
  $file    = $file->cleanup($bool);

Delete ``path'' automatically once the file is not used anymore.

handle

  my $handle = $file->handle;
  $file      = $file->handle(IO::File->new);

Filehandle, created on demand for ``path'', which can be generated automatically and safely based on ``tmpdir''.
