"If you stayed to the end, I, genuinely, really appreciate that... I really do! If you can spend an hour and a half watching a video of mine I really appreciate that..." - man, I didn't spent just an hour and a half here! I was watching it through the course of like, ten/fifteen hours. I was testing the features you were presenting, doing little experiments, reading the documentation and watching other videos. I can say that your video is a good study guide.

[@revillsimon]

“If you watched until the end, I appreciate it.” How could I not watch this until the end? Every video from you is GOLD, Brad. Thank YOU!

[@kasunshashi]

Agreed

[@phat80]

I watch every second video from this channel just to the midde as it usually gets very boring. Some videos are good, some not.

[@bongumusamusambuli8195]

True 100%

[@suganganesan1999]

Just what I was feeling

[@adrienconversanodbl_g5119]

Totally agree, I watched until the last minute

[@andrewbrower4158]

This tutorial is amazing. I love that Brad takes the time to explain the fundamentals, which are skipped over by others all too often. Whenever someone is wanting to learning programming, Brad is always one of the very first I recommend. Thank you for your awesome work, Brad!

[@BekBrace]

I stayed the whole one hour and half watching typing and learning, and I thank you for your great work done in explaining Node.js in plain English ! Thanks once again Brad and be safe

[@ClevergunsYT]

I don't know how. My teacher teaches this for 3 months and u did it in an hour

[@maskman4821]

That's right, a lot of school teachers actually don't know how to teach, they just say things to kill time...

[@chrissabre1761]

Hes paid to stretch it out over the 3 months, and cover a curriculum

[@ClevergunsYT]

And to think he's not a college grad, vs my prof who are in masters degree. He's the absolute good teacher.

[@rosselliot8971]

Work expands to fill the time allotted. If your teacher was paid per student qualified per time taken, well, that would be different.

[@maximilianotorres1225]

Yeah, it sucks how some teachers give you a lot of theory, while Brad goes to the point.

[@RodGaiotto]

Thank you very much for this flawless service to the dev community, Traversy. You are surely one of the best professors I ever had.

[@rongtoob]

You are an amazing teacher! I'm trying to learn this stuff and you've been the only person that has explained it in terms I'm able to grasp! Great job!😁

[@punkgrl325]

So awesome. This is the first tutorial that got me understanding how node is actually used to build and deploy apps. Every other tutorial I came across just claims as long as you understand javascript then node is easy, briefly explain what npm and modules are, and then jump right into express. By contrast, this one really broke down how the core modules actually apply to building a server without express. What a gem. Thanks, Brad!

[@alexmerz4084]

Amazing video, Brad. I totally enjoyed it! The fact that you go through few of the most basic modules says a lot about you approach of teaching in general and I absolutely love. It was refreshing to see a minor nodejs reference work rather than an explanation by means of an example project. You are one of the best programming teachers for sure!

I have followed many of your tutorials for code along and just lecture style learning! Thank you much for your inspiration as well, sharing your story and humility and generosity. I will continue to keep learning and I hope to get my first job as a developer soon, ideally for a cool mission driven company or org.

[@rawestmoreland]

Loved the video, Brad! I've been using React for a while now but have never really learned how node is working under the hood. Looking forward to watching the express tutorial next!

[@robahas]

Very well done. It stays focused, does not introduce too many concepts at once, and every step can be followed by simply paying attention.

[@TinyMaths]

If anybody is struggling with this, especially on Syntax, if you haven't already gone through a short course on ES6, you might find that helpful. Brad mentioned that at the beginning and because I was totally confused I went away and spent a few hours learning ES6 and other things he suggested. For me, it made understanding the functions and methods in this tutorial significantly less difficult. Anyway, this node JS is fascinating; I was apprehensive about taking this course because on first viewing it was like 'Greek' to me. So glad I came back. Can't believe some of the methods it has; like giving you the ability to get system information. It's almost tempting to try to build one of those applications you see online that show you system information - I always wondered how that works. NEVER in my life would I have imagined considering trying a project like that. This JavaScript stuff is truly a rabbit-hole.

[@solomonseidu4435]

This video is over 4 years old, is it still ok to watch and learn or...

[@TinyMaths]

@@solomonseidu4435 I think that, in terms of simplicity, it is quite a good place to start. If you scroll down and read some of the comments from about a year ago, there is some very positive feedback, so I guess the video is still relevant. I must admit though, a few parts were confusing to me because I was a complete beginner, so I had to watch other videos alongside this one, and, as I said above, I had to learn the basics of ES6, which made the course easier after that. Another Node tutorial which I think goes well with this one is from the channel named 'Programming With Mosh' , he has a very good one-hour video for learning node, which might be even more beginner friendly (if that's where you're starting). I went back and forth a lot between the two.

41:19 Brad's iMac's uptime 15 days, wow

[@B20C0]

33:27 if anyone wonders why the file got created despite the error: That's asynchronous functions in a nutshell for you. While asynchronous programming makes your programs execute a LOT faster, this type of behavior might happen, just keep it in mind. So basically if you do this: somefunctionA(); somefunctionB(); If you run those asynchronously and if B relies on A being done, and B is faster than A, you will run into errors.

[@MinneTechie]

Thank you, Brad! This is an easy-to-understand tutorial. You seem to make the learning path straight which saves me from countless hours of potential confusion.

Hey Brad, might be a broad question but if you were told in the morning you can only use one stack what would you pick, ie React/View for FE, Node/Django/PHP for BE, SQL/noSQL for your database, I know project requirements might determine that but just kinda interested what are your favourite tools.

[@TraversyMedia]

lardosian oh you guys and your crazy questions 😏 like you said the project is crucial but for me if i were building something very important not just a little side project I would probably go with MERN. If it were an app with a lot of resources and relationships i may go with sequalize and postgres instead of Mongo.
