A Chrome Notifications API Oddity

·1 min

I’m developing a Chrome extension which is basically the same thing as Key Promoter X in IntelliJ, which reminds you about common keyboard shortcuts you could be using instead of using the mouse like a Plebeian.

I was using the chrome.notifications.create API to create a notification with a passed-in notificationId:

chrome.notifications.create(notificationId, {
  type: "basic",
  title: "Chrome Key Promoter",
  iconUrl: "../icon.jpeg",
  buttons: [{ title: "Silence" }],

However, I could not get the notification to show up no matter what I did. Reloading the extension didn’t help. The documentation clearly states that, if you pass a notificationId:

If it matches an existing notification, this method first clears that notification before proceeding with the create operation.

However, this is not the case. I believe the API documentation is simply out of date, because when I manually cleared the notification beforehand using chrome.notifications.clear(notificationId), the notification starting appearing as expected.

TL;DR if you run into this same issue, just manually clear the notification before creating it.
