NAME

Plack::Middleware::Text::Minify - remove HTML indentation on the fly

VERSION

version v0.3.0

SYNOPSIS

  use Plack::Builder;

  builder {

    enable "Text::Minify",
        path => qr{\.(html|css|js)},
        type => qr{^text/};

  ...

  };

DESCRIPTION

This middleware uses Text::Minify::XS to remove indentation and trailing whitespace from text content.

It will be disabled if the psgix.no-minify environment key is set to a true value. (Added in v0.2.0.)

ATTRIBUTES

path

This is a regex or callback that matches against PATH_INFO. If it does not match, then the response won't be minified.

The callback takes the PATH_INFO and Plack environment as arguments.

By default, it will match against any path except for HTTP status codes with no bodies, or request methods other than GET or POST.

type

This is a regex or callback that matches against the content-type. If it does not match, then the response won't be minified.

The callback takes the content-type header and the Plack reponse as arguments.

By default, it will match against any "text/" MIME type.

KNOWN ISSUES

Support for older Perl versions

This module requires Perl v5.9.3 or newer, which is the minimum version supported by Text::Minify::XS.

Use with templating directive that collapse whitespace

If you are using a templating system with directives that collapse whitespace in HTML documents, e.g. in Template-Toolkit

    [%- IF something -%]
      <div class="foo">
        ...
      </div>
    [%- END -%]

then you may find it worth removing these and letting the middleware clean up extra whitespace.

Collapsed Newlines

The underlying minifier does not understand markup, so newlines will still be collapsed in HTML elements where whitespace is meaningful, e.g. pre or textarea.
