The Bundle System ¶
Caution
In Symfony versions prior to 4.0, it was recommended to organize your own application code using bundles. This is no longer recommended and bundles should only be used to share code and features between multiple applications.
A bundle is similar to a plugin in other software, but even better. The core features of Symfony framework are implemented with bundles (FrameworkBundle, SecurityBundle, DebugBundle, etc.) They are also used to add new features in your application via third-party bundles.
Bundles used in your applications must be enabled per
environment in the config/bundles.php
file:
1 2 3 4 5 6 7 8 9 10 11 12 |
// config/bundles.php
return [
// 'all' means that the bundle is enabled for any Symfony environment
Symfony\Bundle\FrameworkBundle\FrameworkBundle::class => ['all' => true],
Symfony\Bundle\SecurityBundle\SecurityBundle::class => ['all' => true],
Symfony\Bundle\TwigBundle\TwigBundle::class => ['all' => true],
Symfony\Bundle\MonologBundle\MonologBundle::class => ['all' => true],
Doctrine\Bundle\DoctrineBundle\DoctrineBundle::class => ['all' => true],
Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle::class => ['all' => true],
// this bundle is enabled only in 'dev' and 'test', so you can't use it in 'prod'
Symfony\Bundle\WebProfilerBundle\WebProfilerBundle::class => ['dev' => true, 'test' => true],
];
|
Tip
In a default Symfony application that uses Symfony Flex,
bundles are enabled/disabled automatically for you when installing/removing
them, so you don't need to look at or edit this bundles.php
file.
Creating a Bundle ¶
This section creates and enables a new bundle to show there are only a few steps required.
The new bundle is called AcmeTestBundle, where the Acme
portion is an example
name that should be replaced by some "vendor" name that represents you or your
organization (e.g. AbcTestBundle for some company named Abc
).
Start by adding creating a new class called AcmeTestBundle
:
1 2 3 4 5 6 7 8 |
// src/AcmeTestBundle.php
namespace Acme\TestBundle;
use Symfony\Component\HttpKernel\Bundle\AbstractBundle;
class AcmeTestBundle extends AbstractBundle
{
}
|
Caution
If your bundle must be compatible with previous Symfony versions you have to extend from the Bundle instead.
Tip
The name AcmeTestBundle follows the standard
Bundle naming conventions. You could
also choose to shorten the name of the bundle to simply TestBundle by naming
this class TestBundle (and naming the file TestBundle.php
).
This empty class is the only piece you need to create the new bundle. Though commonly empty, this class is powerful and can be used to customize the behavior of the bundle. Now that you've created the bundle, enable it:
1 2 3 4 5 |
// config/bundles.php
return [
// ...
Acme\TestBundle\AcmeTestBundle::class => ['all' => true],
];
|
And while it doesn't do anything yet, AcmeTestBundle is now ready to be used.
Bundle Directory Structure ¶
The directory structure of a bundle is meant to help to keep code consistent between all Symfony bundles. It follows a set of conventions, but is flexible to be adjusted if needed:
src/
-
Contains all PHP classes related to the bundle logic (e.g.
Controller/RandomController.php
).バンドル ロジックに関連するすべての PHP クラスが含まれます (例: Controller/RandomController.php)。 config/
-
Houses configuration, including routing configuration (e.g.
routing.yaml
).ルーティング構成を含むハウス構成 (例: routing.yaml)。 templates/
-
Holds templates organized by controller name (e.g.
random/index.html.twig
).コントローラー名で整理されたテンプレートを保持します (例: random/index.html.twig)。 translations/
-
Holds translations organized by domain and locale (e.g.
AcmeTestBundle.en.xlf
).ドメインとロケールごとに整理された翻訳を保持します (例: AcmeTestBundle.en.xlf)。 public/
-
Contains web assets (images, stylesheets, etc) and is copied or symbolically
linked into the project
public/
directory via theassets:install
console command.Web アセット (画像、スタイルシートなど) を含み、assets:install console コマンドを介してプロジェクトの public/ ディレクトリにコピーまたはシンボリック リンクされます。 assets/
-
Contains JavaScript, CSS, images and other assets related to the bundle that
are not in
public/
(e.g. stimulus controllers)public/ にないバンドルに関連する JavaScript、CSS、画像、およびその他のアセットが含まれています (刺激コントローラーなど)。 tests/
-
Holds all tests for the bundle.
バンドルのすべてのテストを保持します。
Caution
The recommended bundle structure was changed in Symfony 5, read the Symfony 4.4 bundle documentation for information about the old structure.
When using the new AbstractBundle
class, the bundle defaults to the
new structure. Override the Bundle::getPath()
method to change to
the old structure:
1 2 3 4 5 6 7 |
class AcmeTestBundle extends AbstractBundle
{
public function getPath(): string
{
return __DIR__;
}
}
|
Tip
It's recommended to use the PSR-4 autoload standard: use the namespace as key,
and the location of the bundle's main class (relative to composer.json
)
as value. As the main class is located in the src/
directory of the bundle:
1 2 3 4 5 6 7 8 9 10 11 12 |
{
"autoload": {
"psr-4": {
"Acme\\TestBundle\\": "src/"
}
},
"autoload-dev": {
"psr-4": {
"Acme\\TestBundle\\Tests\\": "tests/"
}
}
}
