How to programatically remove all local storage from chrome extension of a specified domain

I would like to with my chrome extension remove all localStorage of a specified domain

when I open the google chrome , I can remove it by going to settings -> All cookies and then find the local storage by the domain name, and delete it manually.

Here is what I get: 

server.myserver.test.com

Local Storage

Source: https://server.myserver.test.com
Disk Size:  5,0 KB
Last modification:  Saturday...

What would I need to do to do this inside my chrome extension, assuming that I have permission for the specified servers to access its cookies.

Thank you!

It looks like it can't be done with Chrome Extension's API. So you'll have to do it manually. Create a content.js script with:

localStorage.clear();

Then in your manifest.json tell it to load the file at the "document_start":

  "content_scripts": [
    {
      "run_at": "document_start",
      "matches": ["<all_urls>"],
      "js": ["content.js"]
    }
  ],

In this case, content.js script will be injected and executed earlier than the website's scripts.

If you want to remove local storage only on the specific domains, you can check for a domain in your content.js file or use matches in manifest.json.

For example, a code below will remove local storage on *.microsoft.com:

const domain = window.location.hostname.split('.').slice(-2).join('.');
if ('microsoft.com' == domain) {
    localStorage.clear();
}

You can run a user script from grease monkey..and clear all the localStorage elements using..

// ==UserScript==
// @name        clearLocalStorage
// @namespace   stackoverflow.com
// @include     http://stackoverflow.com/
// @version     1
// ==/UserScript==
localStorage.clear();

I think you can run content script for that specific Domain and remove local storage data by calling:

localStorage.clear();

Chrome Cookies API removes only cookies.
