I love the idea of showing how to browse documentations, Spring docs are actually simple and on point.
one suggestion is to label (split) the video sections so people can skip parts that are familiar with maybe 🤔
Love your content 👌

Beware!
At the time of my post (February 2024) when you pick the "gateway" dependency, the artifact that comes with it is the which will not work if you follow Dan's tutorial. If things start to fail and you don't know why, that's because of it.
The correct artifact is the spring-cloud-starter-gateway and comes when you pick in the Spring Initializr the "Reactive Gateway".

I have no idea why the change.

great video as always. Can you do a video on how to authenticate jwt using api gateway.

[WaldoRochow]

Thanks for the introduction Dan.
It seems like a good application of this would be an API wrapper where one might add value to the response of the 3rd party API.

Thank you for the tutorial. I learn something new in every your videos. I am curious about how to add security. If clients want to access posts, albums, photos, and todos, they must get valid accessToken first.😅

Great video. Please use some normal font. These hand-written like fonts are hard to read.

Hey, Like you added response header but before forwarding the request can we add a username header?

How to configure routes to use https in uri ? Can you provide code fragment ?

[santhoshbhatti]

Hey Dan, I don't see any documentation on stomp security with Oauth2/ oidc for stomp applications behind a spring cloud api gateway. I am specifically speaking about token relay with stomp messages.
