Last updated January 2025
Our take
Based on the ratings of 14,574 students, a sample of their written reviews and the syllabus, as the course stood in January 2025. No course pays to be reviewed.
This is a code-along for people who already know some React and want to see the whole stack wired together. Academind's Maximilian Schwarzmüller teaches the React and Node/Express parts, and Manuel Lorenz covers MongoDB. The syllabus shows about 18.8 hours over 209 lectures. Each technology gets a short refresher, then a build section, and everything ends up in one complete app. The description is upfront that it does not teach React from the ground up, and the requirements ask for basic React and hooks.
Most of the sample is warm. Of 14,574 ratings, 8,915 are five stars, and reviewers praise clear explanations, a sensible structure and the way the course shows how to plan an app. One likes the detail and repetition. The complaints are consistent too. Several say the pace is fast and the code appears without the reasoning behind it. Others point to outdated code, deprecated functions and workarounds patched in rather than re-recorded. Older reviews add that the CSS is pasted in and that the image storage setup used at the time did not hold up on Heroku.
The course was last updated in January 2025, and reviewers in 2026 still call parts of it dated, so plan to look up fixes now and then. Some enjoy that detective work. Others found it frustrating. If you can debug a version mismatch and want the front end, API, database, upload and login in one project, it is a solid pick. Complete beginners should learn React first.
Pros
- Has a dedicated planning section, and one reviewer says it teaches how to plan an app, not just what to type
- Short refreshers on React, Node and MongoDB before each build section
- Covers file upload, authentication and deployment, not just a basic REST API
- Reviewers call the explanations clear, and one says the detail and repetition help concepts stick
Cons
- Last updated January 2025, yet 2026 reviewers still hit outdated code and deprecated functions
- Fast code-along pace; some reviewers say the reasons behind choices go unexplained
- Not for React beginners; one reviewer called it too complex for a beginner
The course plan is well designed. I've taken several FE-Dev courses on Udemy and this class structure is outstanding. You can learn not only the code, skill but also approach, how to plan when you making App.
Listed for all levels, but the requirements want basic React and hooks first. Node and MongoDB basics help but are optional.
What you will learn
- Learn how to connect ReactJS with NodeJS, Express & MongoDB
- Build an entire project from scratch!
- Refresh the basics about ReactJS, NodeJS, Express and MongoDB
- Learn how to implement Authentication & Authorization

Course Description
We built the bestselling React course on Udemy - this course now allows you to take your React knowledge to the next level and build fullstack web apps based on React, NodeJS, MongoDB and Express!
Building fullstack applications (i.e. frontend + backend) with the MERN stack is very popular - in this course, you will learn it from scratch at the example of a complete project!
MERN stands for MongoDB, Express.js, React.js and Node.js - and combined, these four technologies allow you to build amazing web applications.
In this course, we'll build an entire project and you will learn how these different technologies work together step by step. We'll first have a look at all the individual building blocks, so that we then can also combine them all into one amazing application by the end of the course.
This course also doesn't stop after the basics - instead, you'll also learn how to add file upload, authentication, authorization and how to deploy your application in different ways to different hosting services.
This course is taught by two instructors - Max (React.js, Node/ Express) and Manuel (MongoDB) who have years of experience of working with these technologies and teaching them to other people. We took and combined our experiences to deliver you the best possible MERN stack course you can find out there.
In detail, this course offers:
Brief refreshers on the core technologies (React, Node, Express, MongoDB)
Project sections for each technology where the theoretic knowledge is applied
Detailed theory about the MERN stack and the different ways of combining the technologies
A complete course project where all the technologies come together into one application
File (image) upload in both React.js (sending the file) and Node/ Express (receiving the file)
User authentication (signup + login)
User authorization (controlling access to certain resources)
Detailed deployment instructions - including different ways of deploying the application
Tons of quizzes and extra resources!
By the end of this course, you'll feel comfortable building your own MERN stack applications and you can build up on all the knowledge taught throughout this course to dive into your own projects and use-cases.
What are the requirements for taking this course?
NO prior MERN stack knowledge is required
Basic React.js knowledge is strongly recommended - a refresher is provided as part of the course but this course is NOT meant to teach React from the ground up
Basic Node + Express knowledge is recommended but not a must-have
As always, this course comes with a 30-day money-back guarantee.
We'd love to dive into this course together with you!

It has been challenging. Fortunately, I found an answer for each hiccup, but it has required some perseverance. I'd give it 5 stars, but it took some time to work through issues having to do with older versions and figuring out how to make corrections. The Q&A, along with completed code samples, was a lifesaver, but some things required independent debugging and corrections. Granted, there were a fair number of syntactical and coding issues of my own. One thing I did by myself was to make the necessary routing changes when upgrading from react-route-dom v5 to v6.

very good content, i learned from it a lot, i watched this course in Oct,2024. completed my university senior project and presented it with confidence all with the help of Allah, and the prophet Mohamed (messenger of Allah), and his guardian Imam Ali Bin Abi Talib (if you want to know more about imam ali read "the peak of eloquence" ) special thanks to the amazing instructors Maximillian and his friend. very cool guys. this course will always be recommended for those who decide that it's time to start learning and face the real world with confidence in Allah ( the creator of life ) and in their abilities.

This course is great for beginners, diving deep into some sections and providing alternative approaches and best practices. However, at times it was challenging to grasp concepts, and some parts were confusing. Additionally, some sections need updating, such as React Router, but this doesn't significantly impact the overall experience if you can find the updated information. The QA section helps clarify any uncertainties. However, I had a great time with this course.
By Uriel on 10/6/2022
There are some things that need updating, and the work order in building a real application will not really be like this, but it is built this way on purpose to simplify the concepts and the work order. Max's and Manu explanations are wonderful and the refeshares are great and there is the source code in case you get stuck. It cleared my mind. Recommended for beginner developers. Worth every dollar
By Emmanuel Oloke on 6/29/2022
This was my first full course on Udemy and I must say the Tutor and his team did a great work breaking down all the MERN technologies. I know it's not really a beginner-focused course, but the extra time invested into the React, Node and MongoDB refresher courses goes a really long way in refreshing one's memory and making the course content more understandable. I also love the way the Tutor always spends a short time talking about any new concept or technology he mentions while explaining things, really helps a lot. Overall I'll give this course 5 stars and be sure to recommend it to anyone looking to learn the MERN Stack!.
By Daniel Shaby on 5/20/2022
Good course. Overall really useful learning experience. You get to learn a lot about how to build and deploy a secure, and performance-optimized MERN App. Lots of information on how to connect the front and backend, which was precisely what I was looking to learn. I also expanded my knowledge in React and Node, which is very helpful, including learning “under-the-hood” knowledge of how authentication works. I think what would make this course better is 1) more guidance with the React.js challenging portions—I wouldn't say that “basic” React.js knowledge is sufficient, but rather “intermediate.” I and many other students as demonstrated in the comments felt that some parts of the React.js were challenging to understand, especially with the creating the custom hooks and input validation. In my opinion, I wish Academind taught these challenging lectures a bit better. 2) I was disappointed that in the end, deploying our app wasn't 100% complete, as images, a main part of the MERN app, are not saved onto Heroku's server. One additional lecture regarding connecting to AWS and saving images for more than 24 hours would be helpful. Regardless—thanks for the opportunity. Definitely learned a lot!

The course is really good, wast and Max has put lot of effort. I have learnt so many things and some very complex. Really appreciate Max for his efforts to help us. May be for future lessons, we can build end to end from front end to back end. Instead of front end, back end, then front end and then back end etc.
By Theo Tziomakas on 11/8/2020
5 starts easily. This project will be used as my skeleton for my future applications. I recommend before you start this course, to have a deep look in React Hooks(useState, useEffect, useCallback and so on), because they are used quite extensively, in the frontend. Otherwise you will get confused and not be able able to follow the videos. But don't be scared. Max is a great instructor and explains everything at great depth.
By P C on 8/23/2020
Thank you Max for providing such a wonder full course , it is really helpful. I am React Js developer , working in JavaScript and other UI technologies for many years , in my experience this course will not be very easy for some one new to these technologies , it will be easier if student have some experience in React ,Express and JavaScript,

This is my review after finished the couse. I think this course is for "Practice". You need to have a good knowledge in React, Node and MongoDB. The teaching style may give you very very confuse, since sometimes I didn't know why instructor do this, but after I see the result, I can guess how it works, but it take me for many hours to wrap my head around. I think the instructor should explain the logic or steps and then implement, I think it will avoid the confusion and save my time (Not to go back and forth for rewatch videos). I also disappoint with the project after deployment, since the image is not permanently saved and some security logic like a cookie is not implement. But I rate 4.5 since I do learn more about react-hook especially custom-hook. And this course name is for "Guide Line" purpose, so I think the project is make sense for guildeline. I hope this review is helpful.
