The Reviews
-
Query.gg was amazing! Love the courses the team has put together at ui.dev. I did their JavaScript, TypeScript, and React courses two years ago and still refer back to my notes!
-
I loved the demystification of the library: creating a version of TSQ to see what's happening under the hood. I really liked the variety of real-life scenarios we got the explore! I learned a lot and I think I got a pretty solid grasp on TSQ's philosophy, so reading docs from now on should be a breeze! One thing that's missing is some discussion of TS (I think it warrants at least a chapter for some real life examples) and maybe some more complex cases for mutations, e.g. with `mutateAsync`.
-
Very practical course, was able to apply what I was learning to our codebase immediately. Does a great job of establishing how React Query works behind the scenes so that you can get the most use out of it for your particular use case.
-
React Query has been part of my daily workflow for a while now, but this course really helped me use it more effectively. The challenges actually helped solidify the concepts and they're practical and directly applicable to real work. The course structure does a great job of building up from the basics without making it feel slow for those who already use React Query. Definitely worth it if you want to go from just using it to actually mastering it.

This course is with it's weight in gold and came at the perfect time for me. We are migrating a large app from react-query v3 to v5. Not only do I feel more confident with the migration I now have the a super high level of comfort in my ability to move our app away from some suspect pattens and really leverage all the power of react-query. Thanks for this fantastic course!!!

The team is undertaking the substantial task of refactoring the company's legacy application. We are employing Next.js and RQ, among other backend tools. I am pleased to have gained significant working knowledge from this course, and I am eager to it in practice. Excellent work and thank you.
-
I really enjoyed the React Query course! The combination of theory, questions and practices really worked well.
-
Awesome course, loved the fact that there you can go through the couse through text or video. Also, loved the interactive exercise really cemented the learning.
-
Although I had been using react-query for some time, this course has helped me to get to know it better and to be able to use it in depth.
-
I recently finished query.gg. Besides having a lot of experience with React Query, this course helped me to click some concepts that I've missed. It also contains a ton of content that even if you're a seasoned React Query developer you'll end up learning something.
-
This is the best programming course I've ever taken. I love the format, it's really intuitive, and you can choose if you want to see videos, you got them, you also got the audio and the transcriptions if case you prefer to read. Everything is explained from 0 with great examples, and also, it doesn't only explain how to use or apply React Query, but also how was it built and how does it work behind the scenes.
-
Just finished query.ggâthe theoretical part is put together, explained, and delivered absolutely brilliantly. The course provides a clear understanding of what React Query is, why itâs needed, and how to use it most effectively. A few minor issuesâreally wished I could open videos in full screen with a double click. Also, I often had to reload the page after it had been inactive for some time. Plus, there were some issues submitting certain challenges, but they eventually resolved themselves.
-
You all did such a great job with this course! I would highly recommend this to anyone who is just getting into React Query or looking to expand on their current understanding.
-
The course is very easy to follow, making it accessible even for developers new to React Query. It covers all the essential topics needed to confidently apply React Query in a production-ready project. I appreciated how it starts from the fundamentals, ensuring a solid foundation before diving into more advanced concepts. Highly recommended for anyone looking to master data fetching and state management with React Query!
-
Good way of putting content, great structure and pinch of humor
-
I'm so happy that I took this course. It's really good; I'd be coming to it again and again to reference later. So grateful to the course creators.
-
Really in depth stuff. Will definitely be going back to this for reference.
-
Great course & I love it
-
This course was packed with useful insights and practical tips for using React Query effectively, it helped me uncover the depth of React Queryâs capabilities, from performance optimizations to handling offline scenarios. Highly recommend it!
-
Great course worth every penny. It strikes a great balance of short, digestible content that's information packed.
-
explained the management of asynchronous state really well
-
Pacing is great and there's a lesson that covers just about everything you'll think of during your learning process. If I had one criticism it's that the exercises occasionally don't record completion when you move on to the next lesson and don't preserve the state of the exercise when you come back so you have to do it over. Repetition just helps you get better, though!
-
I was already familiar with React Query and how to use it, but I decided to take this course to gain a deeper understanding of how it works. Iâm so glad I did because now I not only understand how it works on a deeper level but also discovered new features I wasnât using or even aware of! This course has been an eye-opening experience, and I believe itâs absolutely worth the journey. Amazing jobâwell done! đ
-
Just finished react query tutorial. Great going through documentation and explanation that would take a lot of time when going alone. Exercises also helps to understand how RQ works. I can truly recommend.
-
I love Tyler's voice. Listening to his voice in the videos and reading his text in the course feels like someone is talking to me but not watching a video. The course is of great benefit if you really want to understand Tanstack query from ground up. I thoroughly enjoyed it.
-
Person narrating over the videos was very clear and the lessons were easy to follow. I liked that the quizzes explained clearly why the correct answer is correct.
-
This was a fantastic course. I really appreciate the detailed text + video provisions for each lesson. I tend to absorb better through text, but you can see the amount of effort and production value put into the videos. Great challenges, I learned a lot through those. I'm excited to go back through my initial app implementations and flex the new things I've learned!
-
As always, fantastic stuff from ui.dev! I've been using React Query for some of my pet projects for more than a year now, and the course still has taught me so many new things! Loved the exercises and Next.js lessons.
-
I learned alot from this React Query Course!
-
very detailed and described well
-
I really enjoyed the React Query course. Learned a lot from the different approaches presented. Especially, for optimistic updates and query defaults. The combination seems to be very powerful! One thing that occasionally bothers me with RQ is an infinite re-fetching problem when one of the components is conditionally rendered AND using the query of the parent that fails. It's very easy to fall into it and I was expecting some info/tipps to avoid it.
-
Great deep dive into how react query works under the hood. Learnt a lot from this course and now I have plenty of new ideas of how I would use react query in an actual production code base. Highly recommended!
-
Thanks for all the exercises and tests in the course which reinforced whatever is learnt. :)
-
The course was a perfect complement to the already excellent TanStack Query documentation. It helped deepen my understanding and fill in gaps. Huge thanks to the library and course creators for their outstanding work!
-
Not only does this course give a great and granular overview of tanstack query. It also provides some patterns that can immediately provide improvements to your production application.
-
Just finished query.gg - we've increased our usage of react-query significantly over the past year and with almost every module, I had new take-aways or considerations I could immediately apply to improve how we are handling queries. Highly recommended for anyone who's using react-query as an integral part of their stack
-
Everything is great!
-
By far the best course on React Query. Highly recommend it.
-
It's a great course! Thanks y'all!
-
I enjoyed practicing the material provided and performing well.
-
This course offers great insight into the reasons why React Query works as it does. It not only teaches you how to work with React Query specifically, but also about asynchronous data managing and some best practices in general. The quizzes and the challenges immediately put your knowledge to the test. I have already recommend this course to my colleagues and would so to anyone interested in deepening his/her knowledge on React Query.
-
Weâre refactoring a large app to use React Query. The docs have been really useful but this course takes it to the next level. The pace is great, the challenges are actually a challenge and there was still plenty to learn, even after using RQ for a few months. I ended up creating a few refactor PRs in our codebase while following the course.
-
I just completed the course that was outstanding from start to finish. The highlight for me was the initial section, where we recreated React Query from scratch. This deep dive into the core concepts provided a solid understanding of how React Query operates under the hood, which added immense value for someone whoâs been using it for the past three years. The explanations were perfectly clear, making even complex ideas easy to follow. As a result, I've already started applying new techniques at work, especially in how I manage query options, and handle pending and error states. This course genuinely elevated how I approach async state management. Iâd highly recommend it to anyone interested in improving their app's async state management. Whether you're new to React Query or an experienced user, this course is packed with insights that can reshape your approach.
-
This exceptional course offers a well-rounded and in-depth learning experience that caters to beginners and those looking to deepen their understanding of the subject. The combination of video, text, examples, and practical application makes it an invaluable resource. It is highly recommended!
-
What an insightful, engaging and interesting course in React Query! Really glad I had the chance to attend it :-) Thank you!
-
Great course! I love the fact that it's so interactive and doesn't let me lose my focus even for a moment. I think it's a must, if one wants to take advantage of full potential of React Query.
-
Describing the core of react-query, how it works under-the-hood to fully understand what behaviour to expect while using the hooks in production application with industry scaling
-
I learned so much, even in areas I thought I had already mastered. The courseâs pace and depth were perfect, making complex concepts easy to grasp. Highly recommend it to anyone looking to level up their skills with React Query!
-
I needed to learn Tanstack Query quickly for my job, and this course did not disappoint. I came away with not only a solid understanding of the library, but a new appreciation for the possibilities of what online courses could be. Thank you!
-
I had some prior experience with React Query before starting this course, but the initial sections provided excellent refreshers and introduced new insights I hadn't encountered before. As I progressed to the later sections, I gained a deeper understanding and the challenges were instrumental in solidifying my grasp of the material.
-
I just love how the course content flows into the next. Also the videos are not plain old boring videos, they are legit interesting. The storytelling is top-notch!
-
I'm absolutely loving this course. The parts about TanstackQuery that have been confusing to me have been made clear in the course.
-
Started query.gg tonight. production values are insane. im 1/3 in, i would say i'm very experienced with react query and ive already learned several valuable things ask your job to buy it for you, its worth it 10000x. all of the information is in the docs and practical react query, but it's a lot to take in. the course gives the right stuff in the right order.
-
I just completed the http://query.gg course, and if you are using React Query in production, I cannot recommend this course enough! Great work @TkDodo.
-
Brilliant experience. Learned all I needed to know about React Query.
-
I havenât come across any technical writing in recent times that parallels Dominikâs blog posts. Combining them with @uidotdevâs exceptional story telling, I cant even imagine how incredible this course will be. No matter how well you think you know TanStack Query, you'll emerge a more skilled developer with your assumptions challenged!
-
It's good. Real good.
-
Trust me that there's no unwarranted shill when I say that I've never seen tech education quality quite like this new Query course. The uidotdev team are geniuses and Dominik is quite literally our planet's leading expert on all things Query. If you want to learn Query, this is 100% the best way.
