Create an app

After you’ve set up the development environment change into the Nextcloud apps directory:

cd /var/www/nextcloud/apps

Then create a skeleton app in the app store. This doesn’t publish anything on the appstore yet, it just gives you a download.

Edit an existing app

Alternatively, if you would like to contribute to an existing app instead of creating a new one, first set up the development environment, then create an apps-extra folder in the Nextcloud root directory:

cd /var/www/nextcloud/apps-extra

You can then configure Nextcloud to run apps from this directory, by changing your app_paths system config in your config.php

'apps_paths' => array (
    0 => array (
        'path' => '/var/www/html/apps',
        'url' => '/apps',
        'writable' => false,
    1 => array (
        'path' => '/var/www/html/apps-extra',
        'url' => '/apps-extra',
        'writable' => false,

Finally, clone the app to which you would like to contribute inside the apps-extra folder. For example:

Enable the app

The app can now be enabled on the Nextcloud apps page.
