NAME
JSON::Validator::Joi - Joi validation sugar for JSON::Validator
SYNOPSIS
use JSON::Validator::Joi "joi";
my @errors = joi->object->props(
age => joi->integer->min(0)->max(200),
email => joi->regex(".@.")->required,
name => joi->string->min(1),
)->validate({
name => "Jan Henning",
age => 34,
email => "jhthorsen@cpan.org",
});
die "@errors" if @errors;
EXPORTED FUNCTIONS
joi
$joi = joi(%attrs);
Same as:
JSON::Validator::Joi->new(%attrs);
DESCRIPTION
JSON::Validator::Joi is an elegant DSL schema-builder. The main purpose is to build a JSON Schema for JSON::Validator, but it can also validate data directly with sane defaults.
ATTRIBUTES
enum
my $joi = $joi->enum(["foo", "bar"]);
my $array_ref = $joi->enum;
Defines a list of enum values for "integer", "number" and "string".
format
my $joi = $joi->format("email");
my $str = $joi->format;
Used to set the format of the "string". See also "iso_date", "email" and "uri".
max
my $joi = $joi->max(10);
my $int = $joi->max;
array
Defines the max number of items in the array.
integer, number
Defined the max value.
object
Defines the max number of items in the object.
string
Defines how long the string can be.
min
my $joi = $joi->min(10);
my $int = $joi->min;
array
Defines the minimum number of items in the array.
integer, number
Defined the minimum value.
object
Defines the minimum number of items in the object.
string
Defines how short the string can be.
multiple_of
my $joi = $joi->multiple_of(3);
my $int = $joi->multiple_of;
Used by "integer" and "number" to define what the number must be a multiple of.
regex
my $joi = $joi->regex("^\w+$");
my $str = $joi->regex;
Defines a pattern that "string" will be validated against.
type
my $joi = $joi->type("string");
my $joi = $joi->type([qw(null integer)]);
my $any = $joi->type;
Sets the required type. This attribute is set by the convenience methods "array", "integer", "object" and "string", but can be set manually if you need to check against a list of type.
validator
my $joi = $joi->validator(JSON::Validator::Schema::Draft7->new);
my $jv = $joi->validator;
Defaults to a JSON::Validator object. This object is used by "validate".
Note: This might change to JSON::Validator::Schema::Draft7 or a later schema in the future.
METHODS
TO_JSON
Alias for "compile".
alphanum
my $joi = $joi->alphanum;
Sets "regex" to "^\w*$".
array
my $joi = $joi->array;
Sets "type" to "array".
boolean
my $joi = $joi->boolean;
Sets "type" to "boolean".
compile
my $hash_ref = $joi->compile;
Will convert this object into a JSON-Schema data structure that "schema" in JSON::Validator understands.
date_time
my $joi = $joi->date_time;
my $joi = $joi->email;
extend
my $new_joi = $joi->extend($other_joi_object);
Will extend $joi
with the definitions in $other_joi_object
and return a new object.
iso_date
Alias for "date_time".
integer
my $joi = $joi->integer;
Sets "type" to "integer".
items
my $joi = $joi->items($joi);
my $joi = $joi->items([$joi, ...]);
Defines a list of items for the "array" type.
length
my $joi = $joi->length(10);
Sets both "min" and "max" to the number provided.
lowercase
my $joi = $joi->lowercase;

negative
my $joi = $joi->negative;
Sets "max" to 0
.
number
my $joi = $joi->number;
Sets "type" to "number".
object
my $joi = $joi->object;
Sets "type" to "object".
pattern
Alias for "regex".
positive
my $joi = $joi->positive;
Sets "min" to 0
.
props
my $joi = $joi->props(name => JSON::Validator::Joi->new->string, ...);

required
my $joi = $joi->required;
Marks the current property as required.
strict
my $joi = $joi->strict;
Sets "array" and "object" to not allow any more items/keys than what is defined.
string
my $joi = $joi->string;
Sets "type" to "string".
token
my $joi = $joi->token;
Sets "regex" to ^[a-zA-Z0-9_]+$
.
validate
my @errors = $joi->validate($data);
Used to validate $data
using "validate" in JSON::Validator. Returns a list of JSON::Validator::Error objects on invalid input.
unique
my $joi = $joi->unique;
Used to force the "array" to only contain unique items.
uppercase
my $joi = $joi->uppercase;
Will set "regex" to only match upper case strings.
uri
my $joi = $joi->uri;
