Date, Time and DateTime scalar types for our GraphQL implementation

Introduction

Most GraphQL APIs need a way to represent dates, times or timestamps of some sort. Since there is no native date type in GraphQL, people have to resort to rolling their own. To reduce the boilerplate required, this library provides a few basic scalar types that should cover most situations.

Requirements

• PHP >= 7.1
• digiaonline/graphql

Usage

Installation the library using Composer:

composer require digiaonline/graphql-datetime-scalar

When wiring up your executable schema, simply pass in the types you need:

$executableSchema = buildSchema($schemaDefinition, [
    'Query'    => QueryResolver::class,
    'Mutation' => MutationResolver::class,
], [
    'types' => [
        new DateScalarType(),
        new TimeScalarType(),
        new DateTimeScalarType(),
    ],
]);

While it's not strictly necessary it might be a good idea to also mention in your schema that these types exist:

scalar Date
scalar Time
scalar DateTime

You can specify the format by passing a format string to the constructor:

$dateType     = new DateScalarType('j.n.Y'); // 31.12.2018
$timeType     = new TimeScalarType('H:i'); // 14:35
$dateTimeType = new DateTimeScalarType('U'); // 1537361927

Like the built-in scalar types, if a value cannot be serialized or parsed correctly into a \DateTimeInterface, a \Digia\GraphQL\Error\InvalidTypeException will be thrown.
