Course Project:
By end of this course, you will have your own eCommerce app where the users can register, login - search, filter shop products - as well as they can see previous orders, can add products to cart, buy products.
The course project is developed using both Class Components and Function Components in React.
Hooks are main highlight of this course - where you will really learn when-to-use which hook, apart from just how to use it.
We will cover class components up to Section 10.
We will cover complete React hooks from Section 11.
The administrator can control what products should be visible to the users.
It is inclusive of grid operations such as Grid CRUD operations, filter, sort and pagination & REST-API calls.
Let's begin React with an eCommerce project.
You will learn React by doing - practically in this project.
About course:
This course is beginner to intermediate level course, where the developer understands React from scratch (basics) to a meaningful app - by practice.
But you will not miss theoretical details. All essential articles that you need to read are available at end of each section.
You create forms, routing and navigation, component hierarchy, communication from parent-to-child components and vice versa, and also hooks etc., and many more in this course.
You will connect to DB server using JSON-server package (third party npm package) that demonstrates how to make HTTP requests to REST-API servers.
In case if you are a UI developer, sticking to JSON-server is recommended.
This course shows development of sophisticated data grid with all features such as sorting, filtering, paging, http requests (REST API calls) etc.
Please note that, this course sticks to React only - doesn't cover any concepts of server side programming.
This course covers Redux, React-Redux, Redux-Promise, Redux-Saga and Redux-Toolkit in detailed with sample projects.
JavaScript - Exra Lectures
To be frank, you might feel little complications if you don't have sound knowledge of JavaScript, while learning some advanced React concepts. But fortunately, in this course, I am proudly providing extra lectures of JavaScript essential concepts that are required to become master in React - i.e. "JavaScript Functions" "JavaScript Objects", "JavaScript Arrays" and "ES6 Classes".
It is guarantee that if you go through these four sections of JavaScript lectures in this course, you will never confuse to learn any advanced concepts of React - even Redux also.
In case if you find any complication in the middle of React / Redux lectures also, you can refer to the specific topic which you are not aware in the JavaScript extra lectures. It's a big gift for React learners.
POTENTIAL BENEFITS OF THIS COURSE
By the end of this course, you will create all of the source code for a decent eCommerce real-time project, with all features like page navigation with routing, CRUD operations with JSON-server, Forms and validations, component communication and also React Hooks.
You will type in every line of code with me in the videos ... all from scratch.
I explain every line of react code that we create. So this isn't a copy/paste exercise, you will have a full understanding of the code.
I am a RESPONSIVE INSTRUCTOR. post your questions and I will RESPOND in 24 hours, ASAP.
All source code is available for download.
English captions are available.

older version used not recommended at all , content is very older and instructor seems to be in hurry to complete everthing at a very good strech , topic that can be covered in 1 hr has been push to 4 to 5 hours not good examples taken, lot of confusion , seem the instructor is not well education in the field itself
By Yagya Joshi on 10/1/2024
Master JavaScript professional for web development. However, a serious update needs to keep the course relevant. Redux toolkit is not following the docs just twisting, adjusting the old redux. Mind you the functionalities work not breaking but not efficient. For example who uses thunk when it is included in toolkit why use separate reducer component when it can be incorporated in the slices. Store and slices all you need and deploy dispatch fetching with useSelector. There you have redux toolkit. The course has value because the instructor explains every bit and shows with examples.

The content is great, I like that the instructor goes into small details witch most people don't delve into but the pacing could be a little faster. I'm currently required to learn react asap for a project I got assigned to and I need to get productive really quickly and for that the pacing of this course is a little slow for me.

I am amazed at how helpful this course is for beginners. This course is comprehensive and very well organized. The source code is individually provided for each lesson. The instructor, Harsha, is a top-notch teacher. This course is strongly recommended.
By Alfred Amos on 3/17/2022
The instructor has an in-depth understanding of the subject matter and has an excellent ability in teaching the subject matter. He has done an excellent job in putting this course together. It is a very good beginning for those who want to learn React. Well done Harsha.

No beat around bush and the course is packed with lot of content. All topics are covered in an excellent way. I have gone through other React tutorials in Udemy but they take nearly 2 to 3 times additional time to cover the content that is provided in this course. Course is well organised and lot of practical hands-on. If you are a busy developer and want to learn React, even upto advanced level concepts, in short time, this is the best course I feel. Thanks to Harsha for providing this excellent course on Udemy
