Send notification when new node is created

I'm thinking of working on this feature.

Some ideas:

• Alter the content type edit form
• Store the notification template in configuration to keep things simple for now.
• Only send out the notification if the node is published.

Any feedback?

I think this simplest custom approach would be:

function _mymodule_node_presave(\Drupal\node\NodeInterface $node) {
_mymodule_notify_new_users($node);
}

function _mymodule_notify_new_users(\Drupal\node\NodeInterface $node) {
if ($node->getType() !== 'MY TYPE") {
return;
}

// Only send if a new node + is published.
// TODO: enable sending if initially unpublished, then later published
if (!($node->isNew() && $node->isPublished())) {
return;
}

$onesignal = \Drupal::service('onesignal');

$onesignal->addNotification([
"included_segments" => ["Subscribed Users"], // TODO: allow user to customer user
"headings" => ["en" => "English Header"],
"contents" => ["en" => "English Message"],

// optional
"chrome_web_image" => "https://yoursite.com/4x3-with-min-width-1350-large-image",
"chrome_web_icon" => "https://yoursite.com/256x256-icon",
"chrome_web_badge" => "https://yoursite.com/72x72-badge",

// optional
"data" => ["nid" => $node->id(),],
]);
}

Okay, first attempt.

Not multilingual and will probably want to use a service later one. Would love to get some feedback first though :)

Opps - forgot some code clean up

I don't know how to run tests on a MR - so here's the patch!
