What is a Symfony Bundle?
In this new version of Symfony we will not talk about modules or plugins, from now on it is only bundles
A bundle is a directory that holds everything necessary to implement a feature that could be reusable in other projects in the future.
For example we can have a bundle called "CmsBundle" that will handle a CMS system for our web site with articles, comments and users.
Another bundle could be \\\"NewsBundle\\\" that could handle a little news system. As you can see thay are like packages.
Each bundle is hosted under a namespace, that reminds me of Java, so the namespace should begin with your company name or your client name, followed by a sub-name or category and the name of the bundle itself
Bundles name conventions
All classes are referenced under a namespace like MyCompanyName/MyBundle/Entity.
All classes should specify their bundle name, so the first line of a class file should be:
Then if you want to use a class from a namespace in another class:
You can use as many folders as you want but the bundle name will always be the same, you can create a bundle like: My\MyBundle\Folders or a bundle like: My\MyBundleFolders but in both cases the class name will be: MyMyBundleFolders
Onk let's generate a bundle:
php app/console generate:bundle
Let's say that we want the bundle
So for the
Bundle name: MyHelloBundle
Configuration format (yml, xml, php, or annotation): annotation
Do you want to generate the whole directory structure?: yes
Do you confirm generation?: yes
Confirm automatic update of the Kernel?: yes
Confirm automatic update of the Routing?: yes
Now you can chek the app/AppKernel.php file and you will see
Directory structure for the Bundle
| | |---css
| | |---images
| | ---js
You can check on https://github.com/search?langOverride=&language=PHP&q=bundle&repo=&start_value=1&type=Repositories&x=1&y=23
for bundles already developped that you can use
Delete a Bundle
Ok, you've create a HelloWorld Bundle and how do you delete it?
- 1. Delete the bundle source folder: src/My
- 2. Delete the bundle call in the app/AppKernel.php file
- 3. Delete the routing assiciated to this bundle in the file: app/config/routing_dev.yml, see app/config/routing.yml
