Installing and managing apps
============================

Nextcloud apps can enhance, customize or even restrict the features and experience
you and your users has with the Nextcloud server. Next to default enabled functions
like Files, Activity and Gallery there are other apps like Calendar, Contacts,
Talk and more which are enhancing the features of your Nextcloud server.

After installing the Nextcloud server, you might want to consider about enabling,
disabling or even restricting some apps to groups depending on your and your users
needs.

Apps management
---------------

During the Nextcloud server installation, some apps are enabled by default.
To see which apps are enabled go to your Apps page.

Those apps are supported and developed by Nextcloud GmbH directly and
have an **Official**-tag. See :doc:`apps_supported` for a list of supported apps.

.. note:: To get access to work-arounds, long-term-support, priority bug fixing
          and custom consulting for supported apps, contact our `sales team <https://nextcloud.com/enterprise/>`_.

Apps with **Approved** tag are community-developed and were uploaded in the
`Nextcloud App Store <https://apps.nextcloud.com>`_.

.. note:: If you would like to develop your own Nextcloud app, you can find out
          more information in our `developer manual <https://docs.nextcloud.com/server/13/go.php?to=developer-manual>`_.
.. TODO ON RELEASE: Update version number above on release

All apps need to be licensed under AGPLv3+ or any compatible license.

Managing apps
-------------

.. figure:: images/apps_store.png
   :alt: App store page for installing, enabling and disabling apps.

You will see which apps are enabled, disabled and available. You'll also
see additional app bundles and filters, such as Customization, Security and
Monitoring for finding more apps quickly.

In the Apps page you can enable or disable applications. Some apps have
configurable options on the Apps page, such as **Enable only for specific
groups**, but mainly they are enabled or disabled here, and are configured in
your Nextcloud settings (admin and/or user-settings) or in the ``config.php``.

Click the app name to view a description of the app and any of the app settings
in the Application View field. Clicking the **Enable** button will enable the app.
If the app is not part of the Nextcloud installation, it will be downloaded from
the app store, installed and enabled.

Using private API
-----------------

If private API, rather than the public APIs are used in a third-party app, the
installation fails, if ``'appcodechecker' => true,`` is set in ``config.php``.

Using custom app directories
----------------------------

Use the **apps_paths** array in ``config.php`` to set any custom apps directory
locations. The key **path** defines the absolute file system path to the app
folder. The key **url** defines the HTTP web path to that folder, starting at
the Nextcloud web root. The key **writable** indicates if a user can install apps
in that folder.

.. note:: To ensure that the default **/apps/** folder only contains apps
   shipped with Nextcloud, follow this example to setup an **/apps2/** folder
   which will be used to store all other apps.

::

  <?php

    "apps_paths" => array (
        0 => array (
                "path"     => OC::$SERVERROOT."/apps",
                "url"      => "/apps",
                "writable" => false,
        ),
        1 => array (
                "path"     => OC::$SERVERROOT."/apps2",
                "url"      => "/apps2",
                "writable" => true,
        ),
    ),

Using your own appstore
-----------------------

You can enable the installation of apps from your own apps store. This requires that you
can write to at least one of the configured apps directories.

To enable installation from your own apps store:

1. Set the **appstoreenabled** parameter to "true".

   This parameter is used to enable your apps store in Nextcloud.

2. Set the **appstoreurl** to the URL of your Nextcloud apps store.

   This parameter is used to set the http path to the Nextcloud apps store. The appstore
   server must use :abbr:`OCS (Open Collaboration Services)`.

::

  <?php

    "appstoreenabled" => true,
    "appstoreurl" => "https://api.nextcloud.com/v1",
