This is exactly what I have been looking for this whole week, thanks Brad

[ramsimon]

This dude is just such a great guy lol I'm not even into programming/software engineering anymore but I still watch him just because how genuine and thoughtful this guy is, you go Brad!

Wow 2 years later and this is still a masterpiece, learnt alot from you

You have really inspired and helped me in my tech journey

[mudandmoss]

This is insane. I literally just head about this at work today and was planning on looking it up later. I refreshed the YT feed and out pops the exact video I need.

One word: amazeballs. Keep em coming. Love the format and that its short to the point. If I ever want to dig deeper theres almost always more info out there.

One tipp for you: Double clicking variable names, strings and other stuff usually selects exactly what you want. I've seen you drag-select a few times where could have just double-clicked. Saves a ton of time.

Damn, that rate limiting piece is awesome. I've always wondered how to do that!!

[loydcose]

I've never been this overwhelmed how much things i have learn from you, thank you so much!

Hi traversy Media, this is my first time leaving a comment on one of your videos, I just want to tell you that for me you are one of the best we can find on youtube and I always recommend your channel (or udemy courses) to people who want to start learning web dev. All this to tell you that you are doing a wonderful job, keep going !

[fabiandev]

Hey Brad, thanks for all the overviews man, these have helped me on my development journey.

[namangarg]

This was an awesome series. Thanks Brad. Your videos are priceless.

[michadziubich]

That is awsome video, many thanks for all your tutorials. I am also doing your 20 Vanilla JS project course on Udemy and I learned a lot from it. I am starting my first job as junior front end developer next week and a lot of my skills I learned from your extremely helpfull tutorials. Thanks Brad!

I want to thank you for the extremely helpful and straightforward video sir! I've watched tons of guides before but I could finally manage to hide my API key watching this video. You sir are a legend! Keep up the good work! Massive thanks again!

[projectrevolution]

Really enjoyed watching this tutorial, easily explained and so easy to understand.

[Mac_Daffy]

This was really useful and I feel empowered starting my own API proxy from scratch. Thanks for doing these!

[damightyom]

Hahaha This is exactly what I needed about 6 months ago. But I'm still going to watch it, I get to see how good a job I did. Traversy is the best!

Thank you so much! I don't have any basic knowledge of backend dev, and my weather app, which is exactly as yours, is up and running now, and I learned to hide my API key.

[borgestheborg]

I wish I had this tutorial a year ago. Setting up a proxy server is something every web dev should know.
