This tutorial continues my Node.js for Beginners tutorial series, but you can also start here if you already know Node and just want to learn more about the Express JS framework. Express makes working with Node.js clean and easy! If you want to start at the beginning of the Node.js for Beginners playlist, here's a link: th-cam.com/play/PL0Zuz27SZ-6PFkIxaJ6Xx_X46avTM1aYw.html
I was learning express 6 months ago and i looked like a fool just because i bought a useless course on udemy. I'm already feeling like a backend developer a few hours into this series... Thanks a lot, man... You are a real gem..
Great job!
Great pacing. I love how you build on previous basics to provide a clear understanding of higher level structures.
That structure and teaching approach is from my experience as a university instructor. I think it helps most students. Glad you like it!
refactoring a previous project using a new technology, fantastic teacher indeed, thank's so much
Awesome Dave, thanks! You have a knack for making great tutorials! Keep it up please!
Thanks MJ! 💯🚀
Giving a thumbs down to any of these videos should be considered a crime! Great video Dave!!! 👍👍👍👍
Thanks Bruno! 💯
amazing work man, thank you!
Awesome tutorial! Thank you so much!
Powerful tutorial, like other tutorials you share with us thanks alot Dave
You are very welcome! 🙏🙏
Thanks Dave////again and again and again: appreciate your way of delivery which causes many student aw moments : "aw. so that's what that does" !! Thanks for making it all make sense.
Very glad I could help!
great videos, Dave. Thank you
Glad you like them, and I hope they've helped out. 🚀
Thanks teacher Dave!
You're welcome!
Dave Gray, you are a gem💎💎
so far its going good completed first video
the best tutorial I have ever seen.
highly recommended.
Thank you!
Awesome 🥳
Thank you! Cheers!
Love it 🎉
Regexp /* does not mean what you think. However, thanks for a good series.

I loved getting learn about how to add a ()? to make the html portion optional. So cool! Thank you for these! Originally I hadn't learned to include the folder and file name following the __dirname, but instead we did the path to the file in the request. Which one do you think is better practice?
Earlier in this series during the Node JS only tutorials, I touched on this. While both work, I discuss it more here: th-cam.com/video/yQBw8skBdZU/w-d-xo.html
Good video thinks for you ❤👍
Thank you. it's a great video.
Much more to cover for Express. As the last section in the video says, middleware is next. 🚀
@@DaveGrayTeachesCode thank you 21:05 ;)
🚀
Awesome tutorial thank you
Glad you liked it!
@@DaveGrayTeachesCode Thank you
hey Dave thank you for this amazing tuto please if you can create a tuto about linking the reactjs and express and some example thank you
Thanks for asking, and I have - my React Login series uses the backend REST API created in this Node/Express/Mongo series: th-cam.com/play/PL0Zuz27SZ-6PRCpm9clX0WiBEMB70FWwd.html
Thank you
Welcome!
Good day
First, I want to say, Great Course! Thank you so much
I also want to ask about the regex. It says it must have a slash at the beginning and the end, however, sometimes the link says "localhost:3500" and there's no slash but it still works. Can you explain why
Hello, Dave. I am enjoying your course. I was able to get to the last part regarding chaining with no problem. However, when I write localhost:3500/chain in the browser, I get '404'. All my earlier calls such as 'hello' and 'new-page' worked well. Any suggestions as to what I am doing wrong?
I actually watched a whole 1':30" ad video in order to kind of "thank you" lol
Thank you, Tabliqat! 🙏💯
Nice tr
Thank you for your wonderful tutorials as usual!! I finished your vanilla JS, advanced JS and react tutorials and they are amazing.
I wonder, why square brackets are required for [one, two, three] in app.get('/chain(.html)?', [one, two, three]) . Are they necessary?
Not necessary, but it is a possible way to do it. Please read under the heading "Route Handlers" in the docs to see more examples of both: expressjs.com/en/guide/routing.html
thank you
You're welcome!
Please do more for NodeJS express API or JSON
Perfect timing for you to ask. You will like the series I just started creating: th-cam.com/play/PL0Zuz27SZ-6P4dQUsoDatjEGpmBpcOW8V.html
Great lesson keep going forward…is that lesson alternative to that before it
Thanks Haider. The lesson before this one built a web server with only Node.js. In this lesson, we begin to add the Express JS framework on top of Node.js to make things easier. By building with Node.js only first, we gain a better understanding of Node and appreciate what Express does for us as we move forward. 🚀
@@DaveGrayTeachesCode really great work keep going forward… I wonder is there new series coming soon
@@haiderjaafer8164 thank you. 🙏 I'm currently completing this series before beginning another.
so in frontend you must need to logout a user, whenever the refresh token expire right?
That's what I suggest to prevent infinite access. However the refresh token can last for a long duration.
Oh man, this video feels like a schnitzel. Easy to chew and understandable because it isn't that overloaded.
The last video where you build a web server with node.js felt like a big chunk of meat.
I understand that you have to learn the fundamentals but I would prefer express over the vanilla node.
Me too! The fundamentals will help make Express easier sometimes. I like your food analogies! 🌭
Hey dave just wanted to know your opinion i have a university research project in mern stack so is it good to follow along your courses and change them according to my requirements in the real time or do i need to finish these first but iam low in time?? Whats your opinion.
You can apply as you learn. It is close to the end of the semester :)
@@DaveGrayTeachesCode thanks for the reply dave
would you make a tutorial use this api in react js?
That is the plan. Combining this Node.js & Express series with MongoDB and React = MERN stack. Projects using it are coming up.
500th Like 😀!
Yay! Thank you!
