Learn Express Middleware In 14 Minutes

🚨 IMPORTANT:

Use code KYLE for an additional $50

Whether you know it or not you have written middleware if you have done any work with express. Middleware is simply any function that occurs between the time the server receives a request and the time a server sends a response. Understanding exactly how to use middleware effectively, though, can be challenging which is why in this video I cover everything you need to know about middleware in express. I even cover the most common problems I see with middleware at the end of the video.

📚 Materials/References:

🧠 Concepts Covered:

- What express middleware is
- How to define middleware
- How middleware executes
- The biggest middleware problems

Node.Js Senior developer here,
And I'm a subscribed in you channel for two main reasons
1 - Your way to simplify things, even though I know most of them all, I still enjoy watching you explaining them.
2 - No matter how experienced you are, you still can learn some useful tricks from others even for basics.
Keep it up man :)

[jimmymac]

It is ridiculous how good an instructor you are.

[Syed-wjpj]

Dude! every single time, after searching for hours, I end up finding your video and understand a concept.
Never stop
You are a great teacher

Every beginner to backend MUST watch this video. Learning node, express, mongoose, etc all at once, I didn't know where one ended and the other began. This vid and the blog cleared up all the confusion, and your explanation of next() was better than the official documentation. Thanks a lot Kyle, for explaining what middleware really is so well! 😊

[ayushiagarwal]

I have been trying to understand what middleware is for the last two weeks. Went through a ridiculous amount of documentation with no clarification. And then this randomly pops up in my recommendations and everything is suddenly so clear. Thank you so much, Kyle!

[gauravpoudel]

bro thanks again. U r just different from the rest of the tutors out here on youtube. Clear, concise and more importantly teaching best practices

[emanuelsiu]

Everyone else I try to learn from zooms past topics like this and just expects you to get it. Thank you for your clarity and systematic representation of flow and function.

[noidea]

It is actually unreal how good you are at teaching, great job man.

[knoiohi]

The only thing I hate about this video is it ended! This is gold content right here! ❤

[user]

You have a very clear straight to the point way of explaining things, your tutorials are super time efficient to watch, as everything you talk about is relevant to what you're trying to explain.

Hey Kyle, you probably won't see this, but for those who are in the comments, these videos he puts together are amazing. I am currently enrolled in a Software Engineering course, and when we get the new weekly material, the first thing I do is check to see if Kyle has a video on it. Most of the time he does. I have learned so much from you. One day I will land a great job thanks to your videos, and then I will be able to repay you somehow.

I am working on a project using Express and had several questions about middleware. You literally explained all of them one after the other. Amazing work.

[hirenaswar]

this is the best video on middleware on you tube great job mate👍

[zhan]

It's been a while since I enjoyed learning something. I literally laughed! You are definitely one of the best teachers out there!

[simy]

You are a phenomenal teacher, I can always rely on your tutorials if there's anything I don't understand about web dev, your videos are really empowering and super helpful!

[muhammadmoiz]

Luv you man
I spended more than 2 hours in an error in my website but couldn't found so i left it after 2 hours i saw your video and figured out my error luv you so much😄❤❤❤

[weaponizedlego]

Thank you so much for including a blog post too. Love you explanations. But for a quick reference or a lookup on a specific part. The video format is rarely friendly. Love to read guides

[aryanmehta]

Man this was by far the best explanation of middlewares, ,, nothing fancy or complex, just to the point explanation of what needs to be known if you actually want to learn the concept and not some block of code... the explanation after 11:00 is missed by all other videos I have watched on this topic and which is so essential in actual application of middlewares, , ,
for my case I was looking for some kind of explanation of how does logger functions log response times if they are initialized as first middleware as in it should have passed to next middleware before sending response, , , But all is now clear and I am able to digest the functioning of it...

[VladdyHell]

This guy is just an absolute beast. Can't believe I bought a course and didn't understand a thing about express, all I did was to copy til' I watched this video.

[ambarishdashora]

Bro you are like a god of nodejs . I completely understood middle ware. Your video is awesome. Please keep making more such videos. You are a great teacher.
