Download the plugin here

On numerous occasions, I have ran in to the situation where I had to look up how to load Google’s cached version of a particular page. This happens often when I follow a link from Hacker News or Reddit to a blog post and the blog has went down due to the great avalanche of traffic from HN and Reddit.

After struggling to remember and having to Google how to get the cached version, I decided to finally solve this issue. I wrote GetCache, a dead simple Google Chrome plugin that loads Google’s cached version of the current page.

Installing

You can download the plugin here. In order to install it, open your Extensions page (Window -> Extensions) and drag the downloaded CRX file to the page.

Usage

On any page, click on the GetCache icon to load the cached page.

Or you could right click on the page and select View Google's cache.

Source Code

The source code for the plugin is dead simple. All it does is to append http://webcache.googleusercontent.com/search?q=cache: to the beginning of the current URL and ask chrome to load the new URL in the same tab. The interesting bit of the code is below:

(function () {
  var navigateToCachedPage = function (tab) {
    var gCacheUrlPrefix = "http://webcache.googleusercontent.com/search?q=cache:";
    var currentUrl = tab.url;
    var cacheUrl = gCacheUrlPrefix + currentUrl;
    chrome.tabs.update(tab.id, {url: cacheUrl});
  };

  chrome.browserAction.onClicked.addListener(function(tab) {
    navigateToCachedPage (tab);
  });

  chrome.contextMenus.create({
    title: "View Google's cache",
    contexts:["all"],
    onclick: function (clickData, tab) {
      navigateToCachedPage (tab);
    }
  });
}) ();

I used this beautiful icon by Sergio Sanchez Lopez. Since it comes with a GPL license, the plugin is also licensed under GPL.

The source code for the plugin is on Github.

Why is this not on the Chrome store?

I wanted to push it to the Google Chrome web store. But it looks like I need to verify my developer account by paying a sum of USD 5.0. Even worse, I have to create a Google Wallet acount. At this point, I am not so keen to be on the Webstore. In the future, I might get a verified developer account.
