Course Description
In this course, you will learn the MERN Stack by building an amazing e-commerce application from scratch. The application will have not only basic functionalities such as a shopping cart and product search, but also advanced things such as chat, real-time sales charts, product attributes (e. g. product color to choose from), creating testable components in React and other things (see free videos and curriculum).
MERN Stack is a very popular development kit for building web applications. MERN consists of MongoDB (as a database), Express (a framework to make it easier to use Node), React (to create user interfaces), and Node (as a server). You will learn how to combine all four technologies together and build an advanced fully responsive e-commerce application step by step.
In the first part, you will learn the basics of MERN Stack and the JSX extension. Thanks to JSX we can easily create components in React. I will also show you the entire application and give you some tips about VS Code and downloadable resources. And the rest of this course is about covering and going through the steps of creating each MERN Stack application from scratch using e-commerce as example app. I will explain you everything in elegant and understandable way. You will deeply understand Redux using real life scenarios.
We'll start by installing React and creating an HTML template for the entire application (using React Bootstrap). We will link the created subpages with routing
Next, we will install Express JS to handle the Node server for our application
We will connect to the MongoDD database and save example data to this database, such as a list of products for the store
We will create an API through which the frontend will retrieve data from the database, log in to the application, etc.
Once we have the frontend, backend and API, we can connect everything together and develop the application further by supplementing the frontend code with backend operations
We will test our app using Jest & Testing Library
Some of the e-commerce app features:
shopping cart
login, register
PayPal payment
upload images to Cloudinary and to local disk
searching, sorting, filtering, pagination of product list
multilevel categories
bestsellers carousel
star rating system and reviews
real time sales charts using SocketIO
chat using SocketIO
deploy application to Heroku & Render
React local state
Redux state
beautiful functional programming using React Hooks
Much more!

yes, I think, this is the good course for me, becuase we already have learn mern stack and made project, movie card, graphql and apollo, but we are not confident to make from strach, as far as we know, as a intermediate level skills about mern stack. only we need to clarication. How does a web app works? and all over the entire functionality.

muy buen curso con muchas funcionalidades interesantes y utiles para tener de ejemplo a la hora de implementarlas en nuestros proyectos.. una forma particular de implementar react pero bien ordenada y con codigo bastante entendible.. lo recomiendo.

The course and end product is amazing. Lecturer is very knowledgable and explains things very clearly. Best part of the course is how organized the content is. One of the best I've seen so far. I highly reccomend for all levels.

The teaching process was very smooth. The instructor seems to have a lot of experience in this area and every component was explained in great depth and detail. No functionality was skipped in the entire course. Overall a wonderful learning experience.

Learn alot from it already (10% progess). Hope you realse more project like this or maybe even more advance project. Definetly gonna buy your next MERN related course. Your preparation is amazing Can't express how much I love this course
By Nathaniel Motley on 3/21/2023
Yes I'm in a bootcamp and it is really helping me understand React. There are some issues I've been facing but overall really helpful.
By Tingting Wang on 1/19/2023
The redux part is out dated, cannot resolve the "adding to the cart" part. i left message for asking questions but never got reply. Another issue is that I need to go through previous lectures to find the code of a specific part if something goes wrong since the code attached for each lecture is not all the codes, it is only the code modified in that lecture. It would be great if all the most updated code of the whole project could be attached at the end of each module instead of only the code modified in that lecture. But in general, it is a great course and i learnt a lot from it. Thank you!

There is a lot of good information in this course... if you have the time. I wish there was a repo for this course, our at least file downloads at the end of each section rather than only per lecture. there are also some bugs that will take time to sort out.

So Far, I have been Learning up until chapter 19 - I feel like It is very good and useful. I didn't finish the end yet but So Far So Good. Didn't have any bug or it happens to be struck and can't move on in the course yet. It is probably the Instructor knows what he is doing and I am enjoying learning this course. Recommend it!
By Konstantin on 9/14/2022
Very valuable course where I really learned when to use Redux instead of putting everything into it. I especially appreciate the testing section, although short but very informative. Thank you very much for this course!!!
