So we’ll create a manifest.json file and put it into the folder we created. The Manifest file tells Chrome everything it needs to know to properly load up the extension in Chrome. Chrome allows us to load up a plugin by pointing it at a folder that contains the extension files.Īll Chrome extensions require a manifest file. Let’s start by creating a new directory that we’ll call “GTmetrix Extension.” We’ll put all the files we need for our extension in this new folder.

This kind of extension puts a button in the Chrome toolbar that will show an HTML page when clicked and optionally execute some JavaScript.Ĭhrome extensions can also be created to work only on certain pages through the use of Page Actions, they can run code in the background using Background Pages, and they can even modify an existing page loaded in the browser using Content Scripts. In this tutorial, I’m going to show you how to create a basic Chrome extension called a Browser Action extension. An extension is basically just a web page that is hosted within Chrome and can access some additional APIs. If not, are there similar materials I can look at for the same amount of money?

I liked Sonmez's book "Soft Skills" (it was recommended in certain places). I've already completed Coursera's great "Learning How to Learn" course by Barbara Oakley, but want more material on better learning (preferably tailored to programmers). For me, this means not only picking topics, but learning how to learn efficiently. NET shop who doesn't know MVC (others there don't either) and I failed a Coursera course on Data Structures and Algorithms I took a while ago.Įven though my resume has experience, I need to learn a lot to become employable by a big or even medium dog. Just to get a taste of what I'm talking about, I'm a web developer at a. I want a new job as a programmer, but I am so ridiculously far behind the curve. ![]()
