NAME

       Mojo::JSON - Minimalistic JSON

SYNOPSIS

         use Mojo::JSON qw(decode_json encode_json);

         my $bytes = encode_json {foo => [1, 2], bar => 'hello!', baz => \1};
         my $hash  = decode_json $bytes;

DESCRIPTION

       Mojo::JSON is a minimalistic and possibly the fastest pure-Perl implementation of RFC 7159
       <http://tools.ietf.org/html/rfc7159>.

       It supports normal Perl data types like scalar, array reference, hash reference and will
       try to call the "TO_JSON" method on blessed references, or stringify them if it doesn't
       exist. Differentiating between strings and numbers in Perl is hard, depending on how it
       has been used, a scalar can be both at the same time. The string value has a higher
       precedence unless both representations are equivalent.

         [1, -2, 3]     -> [1, -2, 3]
         {"foo": "bar"} -> {foo => 'bar'}

       Literal names will be translated to and from Mojo::JSON constants or a similar native Perl
       value.

         true  -> Mojo::JSON->true
         false -> Mojo::JSON->false
         null  -> undef

       In addition scalar references will be used to generate booleans, based on if their values
       are true or false.

         \1 -> true
         \0 -> false

       The two Unicode whitespace characters "u2028" and "u2029" will always be escaped to make
       JSONP easier, and the character "/" to prevent XSS attacks.

         "\x{2028}\x{2029}</script>" -> "\u2028\u2029<\/script>"

FUNCTIONS

       Mojo::JSON implements the following functions, which can be imported individually.

   decode_json
         my $value = decode_json $bytes;

       Decode JSON to Perl value and die if decoding fails.

   encode_json
         my $bytes = encode_json {i => '♥ mojolicious'};

       Encode Perl value to JSON.

   false
         my $false = false;

       False value, used because Perl has no native equivalent.

   from_json
         my $value = from_json $chars;

       Decode JSON text that is not "UTF-8" encoded to Perl value and die if decoding fails.

   j
         my $bytes = j [1, 2, 3];
         my $bytes = j {i => '♥ mojolicious'};
         my $value = j $bytes;

       Encode Perl data structure (which may only be an array reference or hash reference) or
       decode JSON, an "undef" return value indicates a bare "null" or that decoding failed.

   to_json
         my $chars = to_json {i => '♥ mojolicious'};

       Encode Perl value to JSON text without "UTF-8" encoding it.

   true
         my $true = true;

       True value, used because Perl has no native equivalent.
