"I am primarily a backend engineer who has not been exposed to too much front end or web development. Builderbook has been a great resource that has allowed me to learn several frameworks and design patterns with ease."

Patrick Caughey

"The SaaS Boilerplate book has been super helpful. The first few chapters got me up and running very quickly, and as I re-read them I continued to learn more about the 'why' behind the decisions you made. It's been fun and quite informative!"

Aleksandrs Savkins

"The book is exactly what I was looking for - I needed some guide that will cover the entire processes of creating web apps and saas. I didn't want to waste time and go through many guides, the book is a huge time saver!"

"I want to thank you all for your effort to build up this fantastic project. It is really awesome for full-stack beginners! As one of them, I am using this project to build my own thing, during the implementation I learned a lot, and I might have gave up if I did not choose to purchase BUILDER BOOK! Deeply appreciate that!"

"This is a great book. Clear presentation style. The accompanying code is of very high quality. Your anti-monopoly ideology is also inspiring."

Jennifer K

"I have a Wordpress dev job and it’s nearly impossible for me to get more experience with other technologies without projects like Builder Book. Everyone is doing video courses but I don’t have time to sit through videos. I love being able to read/skim and easily go back through chapters."

Andrew Shrout

"I found builder book using the first book's GitHub repo. From your first book, I was able to relaunch my website: https://michaelstromer.nyc. Thanks for making great content. I learned a lot in your second book, and am finishing up with the deployment this week."

Clayton Hanson

"Builder Book helped me climb out of the Valley of Despair, which is the area between learning basic HTML and being able to code higher functions proficiently. It's rewarding work to get through each chapter and I can't wait to start the SaaS book."

Jamal F.

"I have only just started to read the book. So far I am enjoying the content as it is clarifying the way many of these technologies required to build a web app works. Thus far it is very useful in saving me time without getting bogged down in the beginner details. "

Choo Cheng

Choo Cheng

"I couldn't find many full blown projects built with nextjs and material UI to learn from and your book helped me a lot in connecting the dots. The book could use some diagrams explaining how things integrate with each other and how data flows for a beginner like me. Overall the instructions has been clear and I have no trouble following."

Yannick Wiley

Yannick Wiley
Erie, PA

"I’m a full stack developer and wanted to start to build an MVP to help generate some extra income and continue to build features on top of that. So I begin to search how I could do that using react and being able to render my data on the server side and your builder book product came up. And it attracted my attention, and wanted to try it out myself. So far I’m loving it."

Matt Moyles

Matt Moyles

"I found it very useful in helping to accelerate my next.js learning. I followed along with the book in building the sample app, and then used the async-labs/saas boilerplate to start a new app at my day job. The book definitely helped me get from 0 to 60 on next.js in a shot period of time, and I’m now feeling pretty comfortable with next.js. I also really like the hands on approach. Building a sample app is a great way to learn a new framework!"

Mamadou Diallo

Mamadou Diallo
New York, NY

"Basically the content is good and it's well explained and rich of quality. I learned some features that I was looking to get such as how to combine Express, Next and React as well as Material UI. In addition, I learned some features that I were missing such as how to send out a welcome email. This is a very good real world tutorial that I recommend to developers who are looking to improve their skills."

Eleazar Ramos

Eleazar Ramos

"Going through the book now and it’s excellent. I took a boot camp last year, but haven’t really coded since. It is a great refresher of concepts, and for the new things I’m learning, it explains it concisely! I’ll be using these concepts for a SaaS app that I’m building."

Josh Karamuth

Josh Karamuth

"I have been looking for such a book for a long time because every other course is teaching you how to build todo list apps that nobody cares about. So, thanks a lot for putting out such a resource."

Dmitriy Seleznev

Dmitriy Seleznev

"I've just read first and second chapters of your book. I think, section "Material-UI integration" in first chapter is too complicated. And it can scare away newbies like me. Reading this chapter requires a good understanding of how JSS, React-JSS and Material-UI works. Maybe, if "Material-UI integration" is not a very popular use case, then it can be described in additional materials or in the last chapters. Overall, I'm happy with the book so far."

Drew Page

Drew Page

"I was searching for async/await and found my way to the Async product which led to Builder Book. I'm about halfway through the book and finding it really helpful. Thank you for putting this together. "

Edward Danilyuk

"The intro content along with how you broke things down step by step and didn’t assume I knew how to do something was great. The other great thing is you can pull out any piece (authentication, using the next framework, stripe integration) whatever - and use that piece of knowledge in your project as well."

Eduardo Larrad

"I found the reference of the book in the material-ui site. I think is a great job. Thanks for the effort."

Federico Sananes

"I bought the book because I read the testimonials in your web and saw you were uploading everything to GitHub, that is so brave. You did and keep doing all this work and open-source it. I knew I could just read the code but wanted to support you too. I was searching node information to solve some things I needed to do for a freelance project."

"Acho que já escrevi um review, mas se for possível um novo comentário, até agora estou aprendendo muito, quero agradecer ao idealizadores do livro, maravilhoso."

Justin Cannon

Justin Cannon
San Francisco, CA

"I was actually pretty disappointed, not because I don't think you did a great job writing the book - but because I found that the Next framework abstracts way too much. I'm a fairly experienced developer and was looking for a deeper dive into many things that are just abstracted away by Next. But it does look like an excellent resource for more beginner developers!"

Anonymous Reader

"Because I was a beginner(even now I'm a beginner), I had no idea about server-side and I thought examples would be helpful. I kept searching for examples on the internet and finally found the book on REACT homepage. Your book was well explained, so I could read it easily."

Jason Sprouse

"Builder Book is a labor of love. It's obvious that Tima, Kelly and Delgermurun are not only passionate about software development and architectural design, they are also committed to providing an exceptional learning experience to those who are fortunate enough to read Builder Book. It's stated very clearly in the books introduction, many times we pour over resources and learn a little here and there, but when it comes to organizing everything into a meticulous pattern great for referencing in a new build or elsewhere, there's just not much to rely on short of maybe, our browsers bookmarks. Builder Book excels where our browser's bookmark falls short."

Jacolby Green

Jacolby Green
Plano, TX

"This book is well written and precise. It is easy to understand and very useful. I was not aware of how to get React to render on the server before but I was introduced in this tutorial. One of the most useful things I have learned so far is how to integrate Material-UI with React on the client and server using Next.js."

Mirko Tebaldi

"I was sure it was too expensive but 1) good books require time, 2) I love the 'life time upgrade' plan, 3) the book is teaching about google auth, and this is precious. I already have some prototypes using SSR thanks to your book."

Manot Luijiu

"Most other online courses taught me in 'dev environment' (can't use in real world). Therefore, they made me stuck in 'How to code in prod environment?'. Once I noticed that Builder Book will teach me about real production web app, I immediately purchased it."

Pham Minh Hung

"Your book is amazing. I checked out two books published in 2018 (including BuilderBook) and I liked your book more since it covers things I like and it comes with the promise of updating the book regularly <= really like this."

Scott Horn

"Builder book provides a great foundation for getting started with modern tools and showing reusable examples of gradual app development including login, debugging, logging and deployment."

Rick Hallett

"Some of the code is challenging for a junior, but being stretched is a good experience. The authors have been particularly receptive to open-source issues and pull-requests; this latter point has made my experience a very worthwhile one. Strongly recommended to those going from junior to middleweight JavaScript developers."

Yuri Gor

"Material-UI + Next.js + NoSQL DB - it's exactly what I was trying to build by myself. Finally I found this blueprint project at github. I hope I will evolve the project into my own idea, in production! I highly recommend this book: it keeps good balance between detailed explanations and focus on the target, so you will not lose much time nor something important."

Derek Hammitt

Derek Hammitt

"I'm in the exact place your book describes - feeling more and more comfortable with HTML/CSS/JavaScript, just getting started with React, building an API with Express, and struggling through my first full application. I've leaned Node and Express' docs, and MDN's Express tutorials. Your book is an awesome complement to those resources."

Karolis Stulgys

"The SSR setup is crazy and I have no idea what's going on :) Other than that it's great."

Danh Nguyen

"Very pleased with the book's detailed explanations of design choices and modern web app topics along with the tutorials. In the end you don't just complete the app -you become a far more knowledgeable developer overall."

Dion Pettaway

"As I'm someone who prefers reading to videos, I was hoping this book would be thorough and in depth. Happy to see that it was. I really like the explanations. It definitely solidified a few implementation things I never had a perfect grasp on (lightbulb moment for HOC even though I technically use them)."

Thierry Michel

Thierry Michel
Liège, Belgium

"The way this book breaks things down into steps and explains each chunk of code individually before putting it all together is really helpful. A good example is how they explain why material-ui does not work by default with server-side rendering, how we need to inject the styles and subsequently remove the server-side styles."

Peter Tahinduka

"I had a job interview, and the required frameworks were ExpressJS and React. Through some googling, I landed on this project. I have never been more optimistic about a career as a JavaScript programmer...thanks to Builderbook and the team that put this together.."

"A clear explanation, possibility to see a result of your work step by step and finally get a real full-stack application makes programming a real joy. And the most important, this book pays special attention to a server-side rendering."

Sam Reaves

"I often use Udemy for learning specific technologies, but ended up using Builder Book after being impressed with their brochure site being the actual project you build. The up to date, step by step instructions with Github made creating the app a breeze."

Nicola Niro

"I don't have a lot of experience with server-side rendered React, and Builder Book has taught me a lot about it in a short amount of time. I also never worked with Next.js, and this book has proved an invaluable resource."

Kevin Gómez
