Build an app with React, Redux and Firestore from scratch (Udemy.com)

Learn how to build a web app with React, Redux and Firestore from beginning to publishing

Our take

Based on the ratings of 1,860 students, a sample of their written reviews and the syllabus, as the course stood in November 2025. No course pays to be reviewed.

Neil Cummings teaches this as one long build. Over 26.5 hours and 210 lectures, the course makes a social events app, much like Meetup. It starts with a plain React CRUD app, adds Redux, then brings in Firestore for the data. After that come authentication, profiles, event chat, a following feature, pagination and publishing. Photo upload and cloud functions sit in appendices. The listing says it was re-recorded in April 2025 and last updated in November 2025, with Tailwind and DaisyUI handling the styling. Basic HTML, CSS and JavaScript are expected going in.

Reviewers praise the teaching most. They describe Neil as clear, say he answers questions, and one calls him one of the best instructors they have had. The project also gets credit for feeling like a real-world app. The complaints are about pace and level. Several reviewers say it is labeled beginner but moves fast with little theory, and one felt lost just following along. Another said pagination problems were left unresolved at the end. One caution: the sampled reviews date from 2020 to 2022, so they describe the earlier recording, not the 2025 rewrite.

The numbers are strong. Of 1,860 ratings, 1,277 are five stars and only 24 are one or two stars, and about 11,800 students have enrolled. There are no quizzes or coding exercises, so practice comes from building the app itself. We would point it at someone who has finished a short React intro and wants a large project. Total newcomers should start with a lighter React basics course first.

Best forDevelopers who know basic JavaScript and want one big React and Firebase project to build along with.
Skip it ifYou want React theory explained slowly, or a course with quizzes and coding exercises.

Pros

  • Builds one large events app with maps, live chat, photo upload and a following feature
  • Reviewers say Neil explains each step and answers student questions
  • Goes past React into Firestore queries, pagination, auth and cloud functions
  • Re-recorded in April 2025 and updated again in November 2025

Cons

  • Labeled beginner, but reviewers say it moves fast with little theory
  • No quizzes or coding exercises, so practice comes from the project itself
  • One reviewer said pagination problems were left unresolved at the end
This course goes over basic to more advanced react concept. The instructor is simply one of the best I've had.

Sold as beginner, but reviewers suggest basic JavaScript plus some React exposure first.

Course Description

* Re-mastered, re-imagined and re-recorded in full as at  April 2025*

This course has been completely rewritten and re-recorded from scratch using the tools and techniques available to us to build an application as at April 2025.   

Do you want to learn React and Redux in the context of building a complete application?   Do you want to learn about Firestore, the new Database offering from Google that provides 'live data' to our application?  Are you the type of learner who gets most out of actually building an application rather than watching endless slides about how something is supposed to work?  If so then this course is for you!

In this course we build a complete application from start to finish. 

Every line of code is demonstrated and explained.  We warm up by building a CRUD application in React, we then enhance it by adding Redux and following that we add in Firestore to provide the persistence layer for the application.

Here are just some of the things you will learn about in this course:

  • Setting up the developer environment

  • Creating a React application using the create-react-app utility from Facebook

  • Login and Register functionality using Firebase authentication

  • Adding social login for Facebook and Google into the application

  • Google maps and Places autocomplete integration

  • Photo uploading using drag and drop, with resizing and cropping of the images before upload

  • Adding a live chat system

  • Paging, Sorting and Filtering with Firestore

  • Infinite scroll for the pagination

  • Firestore database design

  • Creating reusable form components with React hook forms

  • Building a great looking application with Tailwind CSS, DaisyUI and Framer Motion

  • Many more things as well

Tools you need for this course

In this course all lessons are demonstrated using Visual Studio Code, a free (and really good) cross platform code editor.  You can of course use your preferred IDE or Code editor of choice and any operating system you like... well as long as it's either Max OSX, Windows or Linux.

Is this course for you?

This course is extremely practical.  About 90% of our time is spent actually building the application.  If you are the type of person who gets the most out of learning 'by doing', then this course will be for you.

Please note that we do not start from zero coding knowledge.   Whilst this is aimed at beginner level, you will need to have some basic javascript knowledge (not a lot is needed) or if you are coming from another programming language then you should be fine with this course.  It's designed to take you from beginner level to having the skills to build a much more significant application.

What do we do on this course

We are building a social events application, much like Facebook events or Meetup.   Building a social application gives us opportunity to build more than just a simple CRUD application.

I am late giving this review, but have now taken several React/Firebase courses ... this is definitely at the top of the list for me! He doesn't only have a nice teaching style, I am already re-using some of the patterns he uses in this course for the single app you build. I will say this, I took this course earlier on and, while I learned a lot, it might need to be noted that some beginners, myself included, may struggle a bit. But it's worth it. Now coming back to review this course, I can fully appreciate what he has done to make it one that does not just teach the library/framework that is React, he helps you think in React. I highly recommend this course, even if you have done other courses. You won't be disappointed!

By Sanjay Bansode on 11/14/2020

Niel react course is best experience one can ask for. It covers all aspects of react using project approach. I enjoyed the course and learned lot from it. The best part is Niel takes time to answer your questions. Highly recommended.

By Barry Pierce on 11/1/2020

Excellent class. Very easy to follow. He packs a lot in and explains concepts clearly.

By Alan Son on 10/26/2020

I don't think people with no experience can follow this. Not what proposed in the introduction.

By J Caganon on 10/18/2020

Awesome contents! It exceeds my expectations. Great Job Neil!

By Krittiya Clark on 10/17/2020

This course starts a basic React to an almost advanced course. I really like this course and Neil responds to all my questions which is terrific.

By Fritz Padilla on 10/15/2020
