# NAME

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

# VERSION

version v0.4.0

# SYNOPSIS

```perl
use Plack::Builder;

builder {

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

...

};
```

# DESCRIPTION

This middleware uses [Text::Minify::XS](https://metacpan.org/pod/Text%3A%3AMinify%3A%3AXS) 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.

# SUPPORT FOR OLDER PERL VERSIONS

This module requires Perl v5.14 or newer.

Future releases may only support Perl versions released in the last ten years.

If you need this module on Perl v5.9.3, please use one of the v0.3.x
versions of this module.  Significant bug or security fixes may be
backported to those versions.

# KNOWN ISSUES

## 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](https://metacpan.org/pod/Template)

```
[%- 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`.
