chrome.tabs.sendMessage when tab is not focused

Question

I have a chrome extension that sends and receives messages back and forth between content and background scripts.

Everything works fine with chrome.runtime, but I am using chrome.tabs.sendMessage to send messages to the content scripts using something like this:

chrome.tabs.query({active: true, currentWindow: true}, function(tabs) {
    chrome.tabs.sendMessage(tabs[0].id, {method: "stuff"}, function(response) { });
});

The extension runs only on a few specific urls, and when that code executes while im on a different tab than the one the extension is running on, or in the background inspect view, it doesn't work.

How can I make it work even when tab is active/focused at the moment the code run?

Answer 1

chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {
 console.log(sender.tab.id);
});

Using sender.tab.id instead of tabs[0].id seems to do the job
