Mojo::JSON \- Minimalistic JSON
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\&  use Mojo::JSON qw(decode_json encode_json);
\&
\&  my $bytes = encode_json {foo => [1, 2], bar => \*(Aqhello!\*(Aq, baz => \e1};
\&  my $hash  = decode_json $bytes;
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Mojo::JSON is a minimalistic and possibly the fastest pure-Perl implementation of \s-1RFC
8259\s0 <https://tools.ietf.org/html/rfc8259>.
.PP
It supports normal Perl data types like scalar, array reference, hash reference and will try to call the \f(CW\*(C`TO_JSON\*(C'\fR
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.
.PP
.Vb 2
\&  [1, \-2, 3]     \-> [1, \-2, 3]
\&  {"foo": "bar"} \-> {foo => \*(Aqbar\*(Aq}
.Ve
.PP
Literal names will be translated to and from Mojo::JSON constants or a similar native Perl value.
.PP
.Vb 3
\&  true  \-> Mojo::JSON\->true
\&  false \-> Mojo::JSON\->false
\&  null  \-> undef
.Ve
.PP
In addition scalar references will be used to generate booleans, based on if their values are true or false.
.PP
.Vb 2
\&  \e1 \-> true
\&  \e0 \-> false
.Ve
.PP
The character \f(CW\*(C`/\*(C'\fR will always be escaped to prevent \s-1XSS\s0 attacks.
.PP
.Vb 1
\&  "</script>" \-> "<\e/script>"
.Ve
.PP
For better performance the optional module Cpanel::JSON::XS (4.09+) will be used automatically if possible. This can
also be disabled with the \f(CW\*(C`MOJO_NO_JSON_XS\*(C'\fR environment variable.
.SH "FUNCTIONS"
.IX Header "FUNCTIONS"
Mojo::JSON implements the following functions, which can be imported individually.
.SS "decode_json"
.IX Subsection "decode_json"
.Vb 1
\&  my $value = decode_json $bytes;
.Ve
.PP
Decode \s-1JSON\s0 to Perl value and die if decoding fails.
.SS "encode_json"
.IX Subsection "encode_json"
.Vb 1
\&  my $bytes = encode_json {i => \*(Aq♥ mojolicious\*(Aq};
.Ve
.PP
Encode Perl value to \s-1JSON.\s0
.SS "false"
.IX Subsection "false"
.Vb 1
\&  my $false = false;
.Ve
.PP
False value, used because Perl has no native equivalent.
.SS "from_json"
.IX Subsection "from_json"
.Vb 1
\&  my $value = from_json $chars;
.Ve
.PP
Decode \s-1JSON\s0 text that is not \f(CW\*(C`UTF\-8\*(C'\fR encoded to Perl value and die if decoding fails.
.SS "j"
.IX Subsection "j"
.Vb 3
\&  my $bytes = j [1, 2, 3];
\&  my $bytes = j {i => \*(Aq♥ mojolicious\*(Aq};
\&  my $value = j $bytes;
.Ve
.PP
Encode Perl data structure (which may only be an array reference or hash reference) or decode \s-1JSON,\s0 an \f(CW\*(C`undef\*(C'\fR return
value indicates a bare \f(CW\*(C`null\*(C'\fR or that decoding failed.
.SS "to_json"
.IX Subsection "to_json"
.Vb 1
\&  my $chars = to_json {i => \*(Aq♥ mojolicious\*(Aq};
.Ve
.PP
Encode Perl value to \s-1JSON\s0 text without \f(CW\*(C`UTF\-8\*(C'\fR encoding it.
.SS "true"
.IX Subsection "true"
.Vb 1
\&  my $true = true;
.Ve
.PP
True value, used because Perl has no native equivalent.
