SYNOPSIS

        artist     => $self->artist,
        genre      => $self->genre,
        is_touring => $self->json_bool( $self->is_touring ),
    } );

    my $data = $self->decode_json($request);

DESCRIPTION

WebApp::Helpers::JsonEncoder is simple role that adds JSON-handling methods to the consuming object. It's dead simple, but since I've copied-and-pasted this about a thousand times, it's time for it to go to CPAN!

This role holds a JSON encoder/decoder object. utf8 support is turned on by default.

METHODS

encode_json( $perl_struct )

Produces the JSON representation of $perl_struct.

decode_json( $json_string )

Turns a valid JSON string into a perl data structure.

json_bool( $value )

Returns the truthiness of $value as a JSON boolean.
