How to catch errors with chrome.browserAction.setBadgeText()

[thdoan]

Most browserAction methods allow me to catch errors such as invalid tab id by checking for chrome.runtime.lastError in the callback -- with the exception of chrome.browserAction.setBadgeText(), which doesn't accept callbacks. With this limitation, how do you guys catch invalid tab ids for chrome.browserAction.setBadgeText()?

To be consistent, I propose making this method return a Promise object as well (similar to setIcon() and other methods) so we can better catch such errors.

Currently there's no reliable way to do so. You can verify the tab id exists using chrome.tabs.get and hope it won't become invalid (closed/replaced) during the call to setBadgeText, but even so it's far from being 100% reliable.

Chrome 67 adds callbacks to all pageAction/browserAction/action methods.

There are no concrete plans for Promises yet so simply continue using a third-party library like Mozilla's WebExtension polyfill.
