Message passing with nested async call in chrome extension fails
Chrome tab.create and tab.getSelectedBackground to content-script of preloading page message failsVariables temporarily undefined outside of chrome.extension.sendMessage callback functionChrome Extension Message passing: response not sentDart chrome extension: How to send a response in onMessage?Message passing with chrome.downloadsChrome extension message passing from popup to contentChrome extension: sendMessage from content to background getting response from popupchrome.runtime.onMessage response with async awaitSend message from content script to another
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty height:90px;width:728px;box-sizing:border-box;
This works: Simple message passing with no nested call to chrome API in the onMessage listener.
content_script
chrome.runtime.sendMessage( message: "what is my windowId?" , function(response)
// clearLocalStorage(response.allWindowsId);
windowId = response.windowId;
console.log(windowId);
);
background_script
chrome.runtime.onMessage.addListener(function(request, sender,sendResponse)
if (request.message === "buttonClick")
chrome.tabs.reload(sender.tab.id);
sendResponse(message: 'handle button click');
else if (request.message === "what is my windowId?")
sendResponse(
windowId: sender.tab.windowId
);
return;
);
This doesnot work: Nested call chrome.windows.getAll in the onMessage listener.
background_script
chrome.runtime.onMessage.addListener(function(request, sender,sendResponse)
if (request.message === "buttonClick")
chrome.tabs.reload(sender.tab.id);
sendResponse(message: 'handle button click');
else if (request.message === "what is my windowId?")
// additional code here
chrome.windows.getAll(function(windows)
sendResponse(
windowId: sender.tab.windowId,
windows: windows
);
);
return;
);
I've also tried to make the call chrome.windows.getAll async using chromeExtensionAsync, but no luck yet.
The following is the error message. It seems that the call to window.getAll happens after the function onMessage returns, even though I've marked this function async by the final return; statement.
Error handling response: TypeError: Cannot read property 'windowId' of undefined
Unchecked runtime.lastError: The message port closed before a response was received.

I just published an OSS library that helps with this case: @wranggle/rpc
Take a look at the BrowserExtensionTransport. It includes an example for making remote calls between a content script and the background window.
