GraphQ...:Scalar(3pm)

💅 NAME 💅

GraphQL::Type::Scalar — it's giving GraphQL scalar type, bestie ✨

---

🦋 SYNOPSIS 🦋

okay so here's the vibe, literally just:

use GraphQL::Type::Scalar;
my $int_type = GraphQL::Type::Scalar->new(
  name => 'Int',
  description =>
    'The `Int` scalar type represents non-fractional signed whole numeric ' .
    'values. Int can represent values between -(2^31) and 2^31 - 1. ',
  serialize => \&coerce_int,
  parse_value => \&coerce_int,
);

no cap, that's the whole thing 🌸

🎀 ATTRIBUTES 🎀

It's got name and description, and those two are coming straight from GraphQL::Role::Named 💜

✨ serialize

Code-ref. Required. not optional, not "maybe later", it's required fr fr 💀

It coerces from a Perl entity of the required type over to a GraphQL entity — or it throws an exception. Those are the options.

bestie listen: it must throw an exception if you pass it a defined (i.e. non-null) but invalid Perl object of the relevant type. That's non-negotiable. But undef? undef must always be valid. always always. 🫶

🌈 parse_value

Code-ref. Required if it's for an input type 🔥

It coerces from a GraphQL entity to a Perl entity of the required type — or, you guessed it, throws an exception. 👑

---

⭐ METHODS ⭐

🌸 is_valid

True if the given Perl entity is a valid value for this type. It's using the serialize attribute under the hood, iykyk 💅

---

👑 EXPORTED VARIABLES 👑

Here's the squad, they come exported:

• $Int
• $Float
• $String
• $Boolean
• $ID

iconic lineup honestly 🎀✨
