How to use Middleware in ASP.NET Core (2 ways of implementing middleware)
Ғылым және технология
Middleware in ASP.Net Core is software components that are assembled into the HTTP pipeline to handle requests and responses. A middleware component can either choose to pass the request to the next component in the pipeline. Or it may choose to end the request. Middleware can perform tasks both before as well as after the next component.
Middleware is nothing but requests delegates which builds the request pipeline. In other words, we can chain requests delegates one after another to build the HTTP pipeline. And each of these requests delegates works with HTTP requests.
In this video, I will walk through how to build middleware to implement custom implementations.
Middleware can be implemented in either of two ways.
The first way is to use one of the existing extension methods:
1. Run
2. Use
3. UseWen
4. Map
5. MapWhen
Or the second way, which is building custom middleware using middleware convention.
The details for implementation of the video is available in my blog here: dotnetcorecentral.com/blog/middleware-in-asp-net-core/
The source code for this blog is available in my GitHub repo here: github.com/choudhurynirjhar/middleware-demo

His videos are super fast and practical so that while watching them you don't get chance to break the rhythm. Also they are based on single topics so no 1-2 hrs videos which you feel when it will get over. I liked his style of teaching. Can you please make some quick videos on Angular too?

@RAM I’m planning to do it, though it will be a series of videos, as it needs some serious time commitments. I’ll start this week, thanks for the feedback. I’m sure a series like that will be useful to a lot of people.

@@temesegenabuhay9408 I am not sure why you will develop a database through middleware for application. Middleware is usually used for things like authrntication/authorization/logging etc or some sort of custom filtering you want to do in request/response before it goes to your application.
