Beautifully explained. I was too confused about middleware and how it works. Now I got a clear picture.

This is awesome. Middleware has always been a fuzzy subject for me but this is helping to make more sense of things. Looking forward to the rest of this series!

Not enough tutorials on middleware related to making your own. Thanks a ton! I've been mulling through many MS docs on the topic w/a blank stare for quite some time with the goal of creating custom middleware that detects IPaddress and other client info from bad actors and wanting to terminate the request when visits (unauthenticated) appear to be coming from spambots and hackerbots (to eliminate the extreme wastefulness of resources when my site(s) are attacked or deluged with bad traffic). I like to log extreme attacks into a queue outside of the web server, asynchronously, for future parsing and hacker profiling - (had a system I wrote years ago that did this from an IIS extension & it worked extremely well and wanted to make it more portable).

Very clear explanation. Building up from doing this directly in the program then moving it to a middleware class made it easy to follow and understand.

thanks for posting Shawn. Looks to me like middleware is technically a node in a linked list, passing request http context to the next node and back recursively.

Looking forward to the next video in the middleware series! Question. Why do you abbreviate context as ctx? I always thought writing "context" made it clearer what it was when browsing over code
@swildermuth
@swildermuth 2 года назад
Old habit, probably not a best practice. I use these common shorter variables: - context: ctx - builder: bldr - options: opt

First time watcher this was a great video, just subscribed. Are you planning on making videos on identity server, authentication or authorization?
@swildermuth
@swildermuth Год назад
Auth, yes. But Identity Server is being replaced by a MSFT tool that won't have runtime license needs.

Thank you very much for the explanation! @swildermuth Why we need AddTransient here and not Singleton?
@swildermuth
@swildermuth Год назад
AddTransient is for stateless objects, where as a singleton is shared by everyone who requests it. I tend to want more Transient (smaller) than Singletons. I only use Singletons if I really have to have shared state (IConfiguration is static as an example).

I thank you for your time and efforts for that tutorial. I usually like your tutorials and I know you by name from many tutorial's series. But this one was about some chaotic useless examples. You did not mention one example that might be really useful about that middleware.
@swildermuth
@swildermuth 6 месяцев назад
yes, it was a useless example to show the simplicity of the middleware. But you could imaging logging and performance in a middleware. I've used it to support caching or early execution of code (e.g. calculate the connection string based on authentication).

awesome content, don’t listen your wife XD… quick question is there an easy/feasible way to time measure all middlewares? yeah, I’m looking at you telemetry….
@swildermuth
@swildermuth 8 месяцев назад
I don't think there is any way to do that out of the box, but I've done this with a small middleware that I plug into different places to see where bottlenecks are, but I'd not use them in production.
@DSSPOA
@DSSPOA 8 месяцев назад
​@@swildermuth That's what I thought, but thanks for answering back =) To make it even complicated, it's happening with a legacy .net framework system, oh boy ...
