Mojo::JSON - Minimalistic JSON
# Encode and decode JSON use Mojo::JSON; my $json = Mojo::JSON->new; my $bytes = $json->encode({foo => [1, 2], bar => 'hello!', baz => \1}); my $hash = $json->decode($bytes); # Check for errors my $json = Mojo::JSON->new; if (defined(my $hash = $json->decode($bytes))) { say $hash->{message} } else { say 'Error: ', $json->error } # Use the alternative interface use Mojo::JSON 'j'; my $bytes = j({foo => [1, 2], bar => 'hello!', baz => \1}); my $hash = j($bytes);
Mojo::JSON is a minimalistic and relaxed implementation of RFC 4627. While it is possibly the fastest pure-Perl JSON parser available, you should not use it for validation.
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.
Scalar
Array
Hash
TO_JSON
[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. In addition Scalar references will be used to generate booleans, based on if their values are true or false.
true -> Mojo::JSON->true false -> Mojo::JSON->false null -> undef
Decoding UTF-16 (LE/BE) and UTF-32 (LE/BE) will be handled transparently, encoding will only generate UTF-8. The two Unicode whitespace characters u2028 and u2029 will always be escaped to make JSONP easier.

u2029
Mojo::JSON implements the following functions.
my $bytes = j([1, 2, 3]); my $bytes = j({foo => 'bar'}); my $array = j($bytes); my $hash = j($bytes);
Encode Perl data structure or decode JSON and return undef if decoding fails.
undef
Mojo::JSON implements the following attributes.
my $err = $json->error; $json = $json->error('Parser error');
Parser errors.
Mojo::JSON inherits all methods from Mojo::Base and implements the following new ones.
my $array = $json->decode($bytes); my $hash = $json->decode($bytes);
Decode JSON to Perl data structure and return undef if decoding fails.
my $bytes = $json->encode([1, 2, 3]); my $bytes = $json->encode({foo => 'bar'});
Encode Perl data structure to JSON.
my $false = Mojo::JSON->false; my $false = $json->false;
False value, used because Perl has no native equivalent.
my $true = Mojo::JSON->true; my $true = $json->true;
True value, used because Perl has no native equivalent.
