Cannot read properties of undefined (reading 'ime')

[Nathan Pierce]

Curious if someone can help me determine where I'm messing this up or what I'm missing:

Manifest:

{

"name": "Vertically Listed Tabs",

"description": "Manage your tabs vertically!",

"version": "0.3.0",

"manifest_version": 3,

"permissions": ["tabs","tabGroups","favicon","storage","system.display","input"],

"action": {

"default_title": "Open the VLT panel window."

},

"background": {

"service_worker": "background.js",

"type": "module"

},

"icons": {

"48": "img/vlticon-48x48.png",

"128": "img/vlticon-128x128.png"

},

"options_page": "options/options.html"

}

The background.js launches a window with an html and js file. In this window's js file, I use a bunch of addListeners for various things. In here, I have:

chrome.input.ime.onKeyEvent.addListener(

(engineID, keyData) => {

console.log(keyData)

}

)

Yet, I see Uncaught (in promise) TypeError:

"Cannot read properties of undefined (reading 'ime')"

According to https://developer.chrome.com/docs/extensions/reference/input_ime/#event-onKeyEvent, this should work.


What am I missing? Is it because this is only supported in the service_worker? IF so, that's insane since the worker is only alive for a few seconds. For context: I need to handle when the user executes (on macos) command + ~.

Just to verify - does the window you open have a chrome-extension:// URL?

I ask because I reckon it will not work in content scripts.

> that's insane since the worker is only alive for a few seconds

The service worker usually wakes up in response to events you listen to, so while that should not be a problem, I am guessing that the overhead of starting the service worker on key press might delay your response and cause a horrible user experience.

Hey! Yep, it has chrome-extension://

I will test it in the service_worker and see what happens.

input.ime api is only available on Chrome OS. As its name, this api is used to implement input method.

For context: I need to handle when the user executes (on macos) command + ~.

Cmd+` is a macOS system shortcut, you can't handle it. But you can use chrome.windows.onFocusChanged.addListener() to know when user focuses on another browser window.
