NAME

    Plack::Middleware::FormatOutput - Format output struct by Accept
    header.

SYNOPSIS

            use Plack::Middleware::FormatOutput;
    
            builder {
                    enable 'FormatOutput';
                    mount "/api" => sub { return [200, undef, {'link' => 'content'}] };
            };

DESCRIPTION

    The Middleware formats output perl struct by "Accept" header param or
    by format param in URL.

    You can get json when define:

      * Accept header application/json

      or

      * Add ?format=application/json to URL

    For complete RestAPI in Perl use:

      * Plack::App::REST

      * Plack::Middleware::ParseContent

CONSTANTS

 DEFAULT MIME TYPES

      * application/json

      * text/yaml

      * text/plain

      * text/html - it uses Rest::HtmlVis as default formatter if installed

PARAMETERS

 mime_type

    Specify if and how returned content should be formated in browser.

    For example:

            use Plack::Middleware::FormatOutput;
            use My::HTML
    
            builder {
                    enable 'FormatOutput', mime_type => {
                            'text/html' => sub{ My::HTML::Parse(@_) }
                    };
                    mount "/api" => sub { return [200, undef, {'link' => 'content'}] };
            };

 htmlvis (if Rest::HtmlVis is installed)

    Define parameters for Rest::HtmlVis.

    For example:

            use Plack::Middleware::FormatOutput;
    
            builder {
                    enable 'FormatOutput', htmlvis => {
                            links => 'My::Links'
                    };
                    mount "/api" => sub { return [200, undef, {'links' => 'content'}] };
            };
