<h1 id="query-complexity-analysis">Query Complexity Analysis</h1>
|
|
<p>This is a PHP port of <a href="http://sangria-graphql.org/learn/#query-complexity-analysis">Query Complexity Analysis</a> in Sangria implementation.</p>
|
|
<p>Complexity analysis is a separate validation rule which calculates query complexity score before execution.
|
|
Every field in the query gets a default score 1 (including ObjectType nodes). Total complexity of the
|
|
query is the sum of all field scores. For example, the complexity of introspection query is <strong>109</strong>.</p>
|
|
<p>If this score exceeds a threshold, a query is not executed and an error is returned instead.</p>
|
|
<p>Complexity analysis is disabled by default. To enabled it, add validation rule:</p>
|
|
<pre><code class="php"><?php
|
|
use GraphQL\GraphQL;
|
|
use GraphQL\Validator\Rules\QueryComplexity;
|
|
use GraphQL\Validator\DocumentValidator;
|
|
|
|
$rule = new QueryComplexity($maxQueryComplexity = 100);
|
|
DocumentValidator::addRule($rule);
|
|
|
|
GraphQL::executeQuery(/*...*/);
|
|
</code></pre>
|
|
|
|
<p>This will set the rule globally. Alternatively, you can provide validation rules <a href="../executing-queries/#custom-validation-rules">per execution</a>.</p>
|
|
<p>To customize field score add <strong>complexity</strong> function to field definition:</p>
|
|
<pre><code class="php"><?php
|
|
use GraphQL\Type\Definition\Type;
|
|
use GraphQL\Type\Definition\ObjectType;
|
|
|
|
$type = new ObjectType([
|
|
'name' => 'MyType',
|
|
'fields' => [
|
|
'someList' => [
|
|
'type' => Type::listOf(Type::string()),
|
|
'args' => [
|
|
'limit' => [
|
|
'type' => Type::int(),
|
|
'defaultValue' => 10
|
|
]
|
|
],
|
|
'complexity' => function($childrenComplexity, $args) {
|
|
return $childrenComplexity * $args['limit'];
|
|
}
|
|
]
|
|
]
|
|
]);
|
|
</code></pre>
|
|
|
|
<h1 id="limiting-query-depth">Limiting Query Depth</h1>
|
|
<p>This is a PHP port of <a href="http://sangria-graphql.org/learn/#limiting-query-depth">Limiting Query Depth</a> in Sangria implementation.
|
|
For example, max depth of the introspection query is <strong>7</strong>.</p>
|
|
<p>It is disabled by default. To enable it, add following validation rule:</p>
|
|
<pre><code class="php"><?php
|
|
use GraphQL\GraphQL;
|
|
use GraphQL\Validator\Rules\QueryDepth;
|
|
use GraphQL\Validator\DocumentValidator;
|
|
|
|
$rule = new QueryDepth($maxDepth = 10);
|
|
DocumentValidator::addRule($rule);
|
|
|
|
GraphQL::executeQuery(/*...*/);
|
|
</code></pre>
|
|
|
|
<p>This will set the rule globally. Alternatively, you can provide validation rules <a href="../executing-queries/#custom-validation-rules">per execution</a>.</p>
|
|
<h1 id="disabling-introspection">Disabling Introspection</h1>
|
|
<p><a href="http://graphql.org/learn/introspection/">Introspection</a> is a mechanism for fetching schema structure.
|
|
It is used by tools like GraphiQL for auto-completion, query validation, etc.</p>
|
|
<p>Introspection is enabled by default. It means that anybody can get a full description of your schema by
|
|
sending a special query containing meta fields <strong>__type</strong> and <strong>__schema</strong> .</p>
|
|
<p>If you are not planning to expose your API to the general public, it makes sense to disable this feature.</p>
|
|
<p>GraphQL PHP provides you separate validation rule which prohibits queries that contain
|
|
<strong>__type</strong> or <strong>__schema</strong> fields. To disable introspection, add following rule:</p>
|
|
<pre><code class="php"><?php
|
|
use GraphQL\GraphQL;
|
|
use GraphQL\Validator\Rules\DisableIntrospection;
|
|
use GraphQL\Validator\DocumentValidator;
|
|
|
|
DocumentValidator::addRule(new DisableIntrospection());
|
|
|
|
GraphQL::executeQuery(/*...*/);
|
|
</code></pre>
|
|
|
|
<p>This will set the rule globally. Alternatively, you can provide validation rules <a href="../executing-queries/#custom-validation-rules">per execution</a>.</p>
