I am developing chrome extension, and the thing that i really need is to get console output as object.

Is it possible to get any of that in chrome extension popup.html/popup.js or somewhere ?

I have tab object, can i get somehow that particular tabs console, or error output from the inspector/devtool in chrome console as object in code?

• javascript
• google-chrome
• google-chrome-extension
• google-chrome-devtools
• google-chrome-app

• do you mean that you want to catch any errors that would go out to the console and then print them to the screen? – Ryan Commented Oct 22, 2012 at 17:41
• When i press extension button (same as when i open extension popup.html / popup.js) i want to get full console output, and do manipulations with it, count errors, count warning, parse in some way output and then display it in the popup html. – XFaktor Commented Oct 22, 2012 at 17:44
• But nevertheless it does not mater what and how i will do it, since i am myself not sure, but first i need to get the output/console/logs/error or whatever we should call it as object in code :) p.s. thanks for trying to help :) – XFaktor Commented Oct 22, 2012 at 17:46
• This must be possible by now, right? – Ryan Commented Dec 17, 2019 at 17:34

Google Chrome Console has no possibility (upon now) to get the Output/Contents of the Console.

There appears to be a way to get console output in an extension, though it requires launching Chrome with a special flag and giving the extension extra file reading permissions.

1. This SO Answer shows how you can have all of Chrome's actions, including console.log() strings, saved in a local file, by launching Chrome with --enable-logging --v=1
2. Then this SO Answer shows how an extension can read that local file.

In your popup.js file you can just use console.log("stuff") then right click on your extension and go to the debugger or inspect_element -> console, to see the output.

From your background file you will need to do:

popup = chrome.extension.getViews('popup'); // this returns an array

popup[0].console.log("stuff");

Then simply do the same steps as above.

See: api get views for more on interaction between views and here for: another way to interact between pages.

There are three JavaScript context in Chrome Extemsion : Content Script, Backgrond Script and Popup. In each context of code you can use console.log(). i.e console.log("I am here");

var tempObject = {'one': 'v_one', 'two', 'v_two'};

console.log(tempObject);

Note: Output will be available only in which context of code you mentioned console.log('Hello');
