In this course, we'll be developing a new Full-Stack Chrome Extension that Scrapes Amazon, and automatically saves Product Data within a MongoDB Database.
Our finished product (which you'll be able to publish to the Chrome Store) will be a Chrome Extension that enables any user to Scrape their own Amazon Purchase History, the results of any Amazon Search URL, or the results of multiple Amazon Search Keywords - one after the next.
Code Samples Included All Along Your Path To Mastering Chrome Extension Development
The Technology Stack you'll be dealing with in this course:
AngularJS (for the Chrome Extension Popup)
jQuery *(for interacting with the Amazon DOM)
The Functionality For the Chrome Extension:
Signup and Login via the Popup View
Select Elements From The DOM with the Content.js Page
Scrape Your Own Amazon Purchase History
Scrape Amazon Search Results of a Given Page
Scrape Amazon Search Results of Multiple Keywords (one after the next automatically)
Save The Amazon Product Title
Save The Amazon Product Description
Save The Amazon Product Image
Save The Amazon Product Reviews
Save The Product Rating
Save The Amount of Ratings of a Given Product
Make The Chrome Extension Automatically Navigate Through All Pages of Search Results
While developing this awesome sample project, you'll learn:
a) How To Scrape Any Data From The Web Programatically via the Power of Chrome Extensions
b) The Manifest.json File
c) The Popup.js File
c) The Background.js File
d) The Content.js File
e) How To Debug Your Chrome Extension
Getting the architecture of your Chrome Extension right is super crucial to keeping your code clean and structured! We'll be covering lots of considerations when building a Full-Stack Chrome Extension.
I built this course because all of the other Chrome Extension courses on Udemy don't go quite as deep (compare the Amount of Hours this course provides relative to the competitors), and because Chrome Extensions are like the surf-suit for websurfers - users can take them with them anywhere they go on the web.
If you're excited about the Awesome Power of Chrome Extensions and Web Scraping, then I hope you get a lot out of this course.
The Architecture is meant to be re-usable no matter what type of Chrome Extension / Web Scraper you'd like to build, so feel to reach out if you need help taking the codebase in your own direction, or if you have any questions along the way.
we are just suggesting the best course for user we are not providing any type of downloadable material
