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 8259 <http://tools.ietf.org/html/rfc8259>. 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.
