GQL Query Loader

A simple library that adds support for .gql and .graphql files in your PHP application.

Features

• Load GraphQL queries from .graphql and .gql files.
• Supports variable replacement within queries.
• Includes fragment files via #include "fragment.graphql" syntax.
• Prevents duplicate fragment loading.

Requirements

• PHP >=8.1

Installation

Install with composer

$  composer  require  cordero-digital/gql-query-loader

Install without composer

1. Download the latest release
2. Extract the .zip or .tar.gz to your machine
3. Copy /src/Loader.php file into your project
4. Include the Loader.php file into the PHP file you need the library into

require_once __DIR__ . '/src/Loader.php';

use CorderoDigital\GQLQueryLoader\Loader;
$loader = new Loader;

Usage

This package supports fragments. The package assumes the fragments are located in a sub directory called /fragments located next to the query.

Variable replacement

This package supports passing PHP values into Graphql files by doing string replacement. This allows you to hardcode your PHP variables into the compiled Graphql query. A couple things to note:

You pass the variables in to the loadQuery() method where the key is the variable name in the Graphql file. Ex:

// Your PHP file
$query = (new  Loader)->loadQuery($this->root  .  'queries/variableNotInArrayExceptionTest.gql', ['id' => 123])->query();

# Your graphql file
query {
	user{{ id }} {
		id
		name
	}
}

# result
query {
	user(id: 123) {
		id
		name
	}
}

If you want multiple hard coded variables on a single object you would do:

// your PHP file
$query = (new  Loader)->loadQuery($this->root  .  'queries/variableNotInArrayExceptionTest.gql', ['id' => 123, 'status' => 'active'])->query();

# Your graphql file
query {
	user{{ id, status }} {
		id
		name
	}
}

# result
query {
	user(id: 123, status: "active") {
		id
		name
	}
}
