@aarshad786 This looks good, thanks for implementing this 🎉 Please list out the keys/configuration which we have to update since as of now you are using your firebase creds. |

Put some comments inline.
Few questions -
- What kind of json data are we sending in payload to display. Can you specify the format here ?
- I see the
appendMessagefunction is commented out. Do you plan to add it to this PR or open a new PR for the UI ? - Will the app constantly listen to the firebase url. Will this have any impact on the general load on the website ?

This is duplicate code. Can you move it to a separate script and import the messaging variable from there ?

This is needed for Firebase-messaging-sw which is basically a background listener all the messages coming in

What I meant is lines 4-14 in this file and line 3-32 in notification.js is duplicte. Please move these lines to separate script and import the messaging variable in both places.

Is the double ! required here ? document.querySelector returns null if element isn't found

converting to boolean value using !! to ensure that token exists.. This can be removed but becomes handy when debugging might be required

Ah so for that shouldn't you be storing !tokenElement in a separate variable and then use it here ? That's how you can debug the variable value for boolean.

So we are assuming here token is already sent to server ?

token can be sent to server from here.. This will be great way to send targeted notifications rather sending to everyone

Thanks for the clarification. Can you mention same in the comment ?

Is this line required ? As per my understanding "sentToServer" should be 1 and it gets set when resetUI() is called after getting permission. Why are we setting it to 0 after that using this function call ?
There was a problem hiding this comment.
We are resetting the variable in storage... once the permission will be received the it is set back again... this is evident in updateUIForPushPermissionRequired() where requestPermission() is called

Shouldn't this line appear before updateUIForPushPermissionRequired() in that case ?

Also it would be good if we can see how the notification looks in different devices i.e in web and the mobile PWA app. |

@aarshad786 Let's leave the review comments for now since we need this ready by tomorrow. Just make sure the notification shows correctly. Work on a simple notification display. We need this ready by tomorrow. @bhansa Can you follow up on this ? |

Due to time constraint, we were not able to add it in the pyconf website. We will be using this template for HydPy for meetup alerts and future conference websites. |
