Get the list of available services

Question

Is there a way to get the list of the available services in Drupal 8?

Answer 1

to Enhance @4k4 answer, because it returns a lot of services names, if you looking for the specified service name, just pass a part of its name

Drush only method

drush eval "print_r(\Drupal::getContainer()->getServiceIds());"

for instances, if you looking for log services

drush eval "print_r(\Drupal::getContainer()->getServiceIds());" | grep "log"

and if you looking for cache services

drush eval "print_r(\Drupal::getContainer()->getServiceIds());" | grep "cache"

Drush with devel module

Devel module offers a nice shortcut for drush

drush devel:services

or use its aliases:

drush devel-container-services

OR

drush dcs

OR

drush devel-services

Drupal console

drupal debug:container

So drush dcs | grep "PART_OF_SERVICE_NAME" will be a good sample to find a serice

Update

in new version you can just do it with drush dcs PART_OF_SERVICE_NAME

( thanks @Cameron to mention this in comment)

Answer 2

The module Devel provides a searchable list (/devel/container/service).

For the command line use Drupal Console:

drupal debug:container

Answer 3

With plain drush, no extra modules required:

drush eval "print_r(\Drupal::getContainer()->getServiceIds());"

If you are searching for a something specific, pipe the output into grep to filter the results, e.g. searching for "views"

drush eval "print_r(\Drupal::getContainer()->getServiceIds());" | grep "views"

Answer 4

\Drupal::getContainer()->getServiceIds() is the REPL friendly way of doing this. Also you can use that on your module code etc..

The services can be also filtered:

preg_grep('/cache/', \Drupal::getContainer()->getServiceIds());

Answer 5

If you are interested to see the available services during development in PHPStorm you can enable the SymfonyPlugin which autocompletes for you the service names (and does much more other handy stuff)

It works both in services.yml and when calling $container->get(...).

Answer 6

A list of services are available on drupal.org https://api.drupal.org/api/drupal/services/8.9.x

Answer 7

There is the PHPStorm Metadata module which can be used to get autocompletion for all services (core, contrib and custom) in PHPStorm. And it also can give you that list.

This module allows to export PHPStorm Advanced Metadata in order to get autocomplete functionality and return type information for next calls:

• Drupal::service()
• ContainerInterface::get()
• EntityTypeManager::getStorage()

After installing and enabling it, run drush phpstorm-metadata:generate and it will generate a file called .phpstorm.meta.php in your Drupal root directory. Inside there is a list of all available services (core, contrib and custom) mapped to their class.

// ...
'theme_handler' =>  \Drupal\Core\Extension\ThemeHandler::class,
'theme_installer' =>  \Drupal\Core\Extension\ThemeInstaller::class,
'entity.manager' =>  \Drupal\Core\Entity\EntityManager::class,
'entity.memory_cache' =>  \Drupal\Core\Cache\MemoryCache\MemoryCache::class,
'entity_type.manager' =>  \Drupal\Core\Entity\EntityTypeManager::class,
'entity_type.repository' =>  \Drupal\Core\Entity\EntityTypeRepository::class,
'entity_type.bundle.info' =>  \Drupal\Core\Entity\EntityTypeBundleInfo::class,
'entity.repository' =>  \Drupal\Core\Entity\EntityRepository::class,
// ...

Since Drupal 8 used Symfony so you can run command php vendor/bin/drupal debug:container and this is equivalent in Symfony php bin/console debug:container
