NAME

JSON::Validator::Joi - Joi validation sugar for JSON::Validator

SYNOPSIS

  use JSON::Validator "joi";

  my @errors = joi(
    {
      name  => "Jan Henning",
      age   => 34,
      email => "jhthorsen@cpan.org",
    },
    joi->object->props(
      age   => joi->integer->min(0)->max(200),
      email => joi->regex(".@.")->required,
      name  => joi->string->min(1),
    )
  );

  die "@errors" if @errors;

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.

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;

Sets "format" to date-time.

email

  my $joi = $joi->email;

Sets "format" to 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;

Will set "regex" to only match lower case strings.

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, ...);

Used to define properties for an "object" type. Each key is the name of the parameter and the values must be a JSON::Validator::Joi object.

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.
