How to make the background.js script run in a chrome extension? [duplicate]

Question

I'm new to creating chrome extensions and I just want to get all cookies from the sites that I visit. The issue is that when I load a site nothing happens. I get no errors and no logs for the cookies that I want to get. Can anyone help me understand what I'm doing wrong? Thanks!

manifest.json

{ "manifest_version": 2, "name": "xxxxxxxx", "version": "0.8", "permissions": [ "cookies", "tabs", "http://*/*", "https://*/*", "<all_urls>" ], "background": { "scripts": ["background.js"] } }

background.js

function cookieInfo(){ chrome.cookies.getAll({}, function (cookies){ console.log(cookies) }); } cookieInfo();

@Barmar I don't think so, honestly not sure where I'm going wrong here. — Michael

Then it sounds like your question is actually how to make the background script of a chrome extension run. The cookie stuff is irrelevant. — Barmar

The background script needs to register a listener for an API event, otherwise it rarely makes sense to use a background script. Your current code will run only once when the extension runs on browser startup or after it was re-enabled or re-installed. In other words it doesn't do anything particularly useful. Depending on your preferred method of learning you may want to start with the documentation/tutorial or just inspect the official demo extensions. — woxxom

Background scripts do not log to a specific web page's console. Visit chrome://extensions/ and click on "Inspect views background page" for your extension.
