I am looking for a solution to listen notifications with my chrome extension.
But chrome.notifications only allows me to send notifications but not listening to notifications.
So is there any way to solve this problem? Thanks.

I am trying to build a PWA (Progressive Web App) but the Chrome devtools console is warning that it is blocking my css and icon file.
Request was blocked by DevTools: "https://example.com/styles/style.css".
I cannot find any information about this happening automatically and, to my knowledge, should only happen if the user has manually requested to block a script. Chrome does not offer any other information about the warnings other than being blocked.
This error means the domain or URL has been blocked in the devtools. Most of the time, it's just because the developer blocked the request without paying attention.
To unblock it, just follow these steps:
Open your devtools
Go to the network tab
Right-click on the request that blocked
Then click Unblock <request-url>
I am learning to make chrome app which will receive UDP packets from remote device. All works perfectly fine, however, in order to receive packets from remote device I need to turn off windows firewall.
Now the problem is that I do not see a way to add this app to pass firewall exception. Because I only see option to allow Chrome through firewall, not any of its apps.
What is the solution / workaround to this problem?
Thanks
Since I didn't get any answer, the best possible solution I could find so far is to add the port on which my chrome app will listen to firewall inbound rules. I didn't know this was possible until i read this article https://www.thewindowsclub.com/block-open-port-windows-8-firewall
However I still don't consider it the right solution because lets say I publish my app online for other people, it will not be convenient for them to be adding rules to their firewalls.
I am sure there must be a better solution.
I would like to be able to send messages from an App Engine server to a Chrome extension. When the Chrome extension receives a message, it should increment the badge over the icon. Is it possible to send messages directly, or do I have to poll the server continuously from the extension?
You should look into the Cloud Messaging API, specifically chrome.gcm API.
This would be the best way to notify the extension from the server side, and can be a two-way communication channel.
I want to build a Chrome App to listen notifications sent by my Lab, and I don't want to open a Chrome window(just let the app run in background silently, and pop a box when I have a new message). But sockets api is only for packaged app, and packaged app has no background permission, what should I do? Thx.
(Quick answer, will edit later with more info.)
Chrome Packaged Apps don't need that permission, they have a background page by default. Most (say, 99% of existing) chrome apps will open a window when they launch, but thats optional.
If your app has an open window, the runtime will keep your application running an not move into an idle state. However, if you are using certain APIs, such as having an open TCP server socket listening for incoming connections, its very unlikely that the runtime will shut your app down unless the system is under serious constraints.
I'm developing a Google Chrome Extenstion, I wonder if there is anyway to show desktop notifications even if Chrome is closed, maybe some sort of background process or service? Kindly advice and guide me if it is not possible also. Thanks.
If you request a "background" permission your extension's background page will be able to show notifications even with Chrome windows closed.
When any installed hosted app, packaged app, or extension has "background" permission, Chrome runs (invisibly) as soon as the user logs into their computer—before the user launches Chrome. The "background" permission also makes Chrome continue running (even after its last window is closed) until the user explicitly quits Chrome.
If you use Google Chrome, you can enable a new Gmail feature that shows desktop notifications for new messages. Go to "Settings", and enable chat notifications and mail notifications to see a small bubble when you get a new message.
Secondly: Using WCF or Windows Services:
you have to develop simple client on machine polling a central service for alerts. Each alert should have a unique id so each client can deal with idem-potency
I Hope that this will be helpfull to you
