Even if it is possible that it can be built in Chamilo, it also makes sense to have this independent.
Like https://gotify.net

Not sure yet we'll do this in Chamilo 2.0. Seems to be very little interest for that so far (as per comments on this issue)

Hello Yannick,

two options: either browser push or app.
Otherwise Chamilo will fallback even more behind Moodle.
What do you think, why the usage is not that widespread? :-)

[ywarnier]

Apparently Gotify is a great Open Source push notifications servers (in Go). This could be useful for debugging/testing. Enabling push in Chamilo 2 should ideally let the user define which push notification server to use (although I suppose the mobile app then needs to offer to reconfigure the push notifications servers as well).

It is implemented with this PR #6421

Implemented features

• Users can subscribe/unsubscribe to browser push notifications from their profile.
• Works in Firefox and Chrome, over HTTPS with a valid SSL certificate.
• Chamilo 2 can now send browser push notifications for:

Direct messages
Activity alerts
Custom notifications

Technical changes

• New database table:
  push_subscription
  storing:

endpoint
publicKey
authToken
contentEncoding
userAgent
user_id relation
timestamps

• New platform setting push_notification_settings :

{
"gotify_url": "http://localhost:8080",
"gotify_token": "A0yWWfe_8YRLv_B",
"enabled": true,
"vapid_public_key": "BNg54MTyDZSdyFq99EmppT606jKVDS5o7jGVxMLW3Qir937A98sxtrK4VMt1ddNlK93MUenK0kM3aiAMu9HRcjQ=",
"vapid_private_key": "UgS5-xSneOcSyNJVq4c9wmEGaCoE1Y8oh-7ZGXPgs8o"
}

• Example backend controller implemented:

/push-notifications/send/{userId}
Allows sending a test notification to all registered subscriptions for a user.

/push-notifications/send-gotify
Supports sending via web push or Gotify.

• Uses Minishlink/WebPush PHP library for handling Web Push protocol. Requires running: composer install

It requires testing. Thanks for confirmation.
