Named Serializers
1476+
-----------------
1477+
1478+
.. versionadded:: 7.2
1479+
1480+
Named serializers were introduced in Symfony 7.2.
1481+
1482+
Sometimes, you may need multiple configurations for the serializer, such
1483+
as different default contexts, name converters, or sets of normalizers and
1484+
encoders, depending on the use case. For example, when your application
1485+
communicates with multiple APIs, each with its own set of rules.
1486+
1487+
This can be achieved by configuring multiple instances of the serializer
1488+
using the ``named_serializers`` option:
1489+
1490+
.. configuration-block::
1491+
1492+
.. code-block:: yaml
1493+
1494+
# config/packages/serializer.yaml
1495+
framework:
1496+
serializer:
1497+
named_serializers:
1498+
api_client1:
1499+
name_converter: 'serializer.name_converter.camel_case_to_snake_case'
1500+
default_context:
1501+
enable_max_depth: true
1502+
api_client2:
1503+
default_context:
1504+
enable_max_depth: false
1505+
1506+
.. code-block:: xml

1540+
1541+
// config/packages/serializer.php
1542+
use Symfony\Config\FrameworkConfig;
1543+
1544+
return static function (FrameworkConfig $framework): void {
1545+
$framework->serializer()
1546+

1547+

1555+
'enable_max_depth' => false,
1556+
])
1557+
;
1558+
};
1559+
1560+
You can inject these different serializer instances
1561+
using :ref:`named aliases <autowiring-multiple-implementations-same-type>`::
1562+
1563+
namespace App\Controller;
1564+
1565+
// ...
1566+
use Symfony\Component\DependencyInjection\Attribute\Target;
1567+
1568+
class PersonController extends AbstractController
1569+
{
1570+
public function index(
1571+
SerializerInterface $serializer, // Default serializer
1572+
SerializerInterface $apiClient1Serializer, // api_client1 serializer
1573+
#[Target('apiClient2.serializer')] // api_client2 serializer
1574+
SerializerInterface $customName,
1575+
) {
1576+
// ...
1577+
}
1578+
}
1579+
1580+
Named serializers are configured with the default set of normalizers and encoders.
1581+
1582+
You can register additional normalizers and encoders with a specific named
1583+
serializer by adding a ``serializer`` attribute to
1584+
the :ref:`serializer.normalizer <reference-dic-tags-serializer-normalizer>`
1585+
or :ref:`serializer.encoder <reference-dic-tags-serializer-encoder>` tags:
1586+
1587+
.. configuration-block::
1588+
1589+
.. code-block:: yaml
1590+
1591+

1592+
services:
1593+
# ...
1594+
1595+
Symfony\Component\Serializer\Normalizer\CustomNormalizer:
1596+
# Prevent this normalizer from automatically being included in the default serializer
1597+
autoconfigure: false
1598+
tags:
1599+
# Include this normalizer in a single serializer
1600+
- serializer.normalizer: { serializer: 'api_client1' }
1601+
# Include this normalizer in multiple serializers
1602+
- serializer.normalizer: { serializer: [ 'api_client1', 'api_client2' ] }
1603+
# Include this normalizer in all serializers (including the default one)
1604+
- serializer.normalizer: { serializer: '*' }

1640+

1641+
1642+

1643+
1644+
return function(ContainerConfigurator $container) {
1645+

$services->set(CustomNormalizer::class)
1648+

1655+
// Include this normalizer in all serializers (including the default one)
1656+
->tag('serializer.normalizer', ['serializer' => '*'])
1657+
;
1658+
};
1659+
1660+
When the ``serializer`` attribute is not set, the service is registered with
1661+
the default serializer.
1662+
1663+
Each normalizer and encoder used in a named serializer is tagged with
1664+
a ``serializer.normalizer.<name>`` or ``serializer.encoder.<name>`` tag,
1665+
which can be used to list their priorities using the following command:
1666+
1667+
.. code-block:: terminal
1668+
1669+
$ php bin/console debug:container --tag serializer.<normalizer|encoder>.<name>
1670+
1671+
Additionally, you can exclude the default set of normalizers and encoders by
1672+
setting the ``include_built_in_normalizers`` and ``include_built_in_encoders``
1673+
options to ``false``:
