chrome.management.onInstalled.addListener throwing Uncaught SyntaxError: Unexpected identifier

I am trying to write a chrome extension to listen to the install / uninstall / enabled / disabled events for other extensions either by using chrome web store or by other means.

I am planning to use the chrome.management module for that.

  1. I had declared the permissions in the manifest.json file.

    "permissions": [
    "management"
],

  2. I have a background.html page

    "background": {
    "page": "background.html"
},

  3. I had included the background.js as a part of the background.html page

    <html>
<script type="text/javascript" src="js/background.js"></script>
<body>
</body>
</html>

  4. And here is my background.js

    chrome.management.onInstalled.addListener(function(ExtensionInfo info) {
  console.log('somethingz installed...');
  printInfo(info);
  });

chrome.management.onEnabled.addListener(function(ExtensionInfo info) {
  console.log('somethingz enabled...');
  printInfo(info);
});


chrome.management.onDisabled.addListener(function(ExtensionInfo info) {
  console.log('somethingz disabled...');
  printInfo(info);
});


function printInfo(info)
{
  console.log("id: " ++ info.id);
  console.log("name: " ++ info.name);
  console.log("description: " ++ info.description);
  console.log("version: " ++ info.version);
  console.log("mayDisable: " ++ info.mayDisable);
  console.log("enabled: " ++ info.enabled);
  console.log("disabledReason: " ++ info.disabledReason);
  console.log("type: " ++ info.type);
  console.log("appLaunchURL: " ++ info.appLaunchURL);
  console.log("homepageUrl: " ++ info.homepageUrl );
  console.log("updateUrl: " ++ info.updateUrl  );
  console.log("offlineEnabled: " ++ info.offlineEnabled);
  console.log("optionsUrl: " ++ info.optionsUrl);
  console.log("icons: " ++ info.icons);
  console.log("permissions: " ++ info.permissions);
  console.log("hostPermissions: " ++ info.hostPermissions);
  console.log("installType: " ++ info.installType);
}

I am trying to debug the background.html page by looking at the chrome://extensions page and I am seeing -

    Uncaught SyntaxError: Unexpected identifier

and the events are not firing as expected because of this error.

Please help!! not sure what is causing the "Uncaught SyntaxError: Unexpected identifier" error... May be it is something too basic, however, I am not able to catch it by looking at it for quite some time!

Your code has 2 major problems. First you include the type of the parameters in the listeners, in this case the ExtensionInfo, remove that. Second, you are using 2 + change it to 1. The resulting code looks like this:

chrome.management.onInstalled.addListener(function(info) {
  console.log('somethingz installed...');
  printInfo(info);
});

And this

function printInfo(info){
  console.log("id: " + info.id);

As a side note, instead of manually logging every part of info, you can just do something like this:

console.log(JSON.stringify(info).replace(',','\n'));
