Chrome extension in Angular 2/4

Question

I am trying to create a chrome extension for google chrome browser using Angular 4. I just need the url and title of the page, where I am clicking on the browser icon(click event). So far I have done following things

I have created a eventPage and that page is getting called when I click the icon of extension. Code=>

if (typeof chrome.browserAction !== 'undefined') {
    chrome.browserAction.onClicked.addListener(function(tab) {
        listService.getBookmarks().then(bookmarkLists => {
            bookmarkLists = bookmarkLists;
            getSelectedTab(bookmarkLists);
        });
    });
} else {
    console.log('EventPage initialized');
}

function getSelectedTab(bookmarkLists) {
    chrome.tabs.getSelected(null, function(tab) {
        let newBookmark: Object = {
            name: tab.title,
            url: tab.url
        };
        bookmarkLists.push(newBookmark);
        listService.setBookmarks(bookmarkLists);
    });
}

listService.getBookmarks => listService has a method getBookmarks which already has some data as key, value pair.

IF anybody can tell just how to get the URL and Title of the page where I am triggering click on the extension click.

This is how I got the url and title in extension

var that = this;
chrome.tabs.query({
    currentWindow: true,
    active: true
}, function(tabs) {
  console.log(tabs[0]);
  if (tabs.length > 0) {
    if (tabs[0].url !== undefined && tabs[0].url !== null && tabs[0].url !== '') {
      that.tabId = tabs[0].id;
      that.tabURL = tabs[0].url;
      that.tabTitle = tabs[0].title;
      that.favIconUrl = tabs[0].favIconUrl;
    }
  }
});

include this file on top of the component
