HTTP Interceptors |Multiple Interceptors | Interceptors UseCases (Tutorial 37)

► Interceptors are a unique type of Angular Service that we can implement. Interceptors allow us to intercept incoming or outgoing HTTP requests using the HttpClient. By intercepting the HTTP request, we can modify or change the value of the request.
We can perform various operation using interceptors like:
•
► Modifying HTTP Headers
► Modifying request body
► Interceptors can be used to set authentication and authorization token.
► If you want to mock the backend API, there also interceptors are life saver.
►
If you want to modify thee response, like you got the response in XML and want to convert it to JSON, Interceptors are helpful.
►We can leverage Interceptors to also handle HTTP errors
So Useful things we can do with Http Interceptors are endless

So nice of you.. thank you 😊

[@rajeshmeena3445]

Hello ma'am, I would like to request you if you are thinking about making videos on angular unit testing and State management it would be a great help for all the angular developers because you are trying to explain core concepts of every single topic and not only me but everyone likes it and grabs it. It was such an awesome experience while watching your videos. Thanks a lot for the kind of knowledge you are sharing.

[@tuktuk00794]

loved the way you are explaining🥰

@Nisha Singla, Thanx for creating such a great angular series, you covered everything in detail with proper examples 🙌. I request you to create videos on angular authentication/Auth2.0/ADFS/angular-oauth2-oidc

[@PratikBokey]

Excellent Video :)

[@karanshah6104]

Hi NIsha, I have seen many videos of Angular on KZbin. Your content-quality is at high level when compared to others. But in your few videos your voice is load and clear, in some it is suppressed. You can feel the difference after comparing this video to your content-projection video in same playlist. Though at last I would like to request you to make complete project using Angular and Typescript. Which involves industry level authentication feature too. It'd be Diamond for serious learners.

[@yelendisuresh7627]

Angular videos are really good, can you please make video's on state management like ngrx, redux,mobix

[@brianryan4053]

We have classes in Typescript, so we do not need state management in Angular, we use classes for this. This is an advantage of Angular over React and Vue.

@@NishaSingla I am so happy to get your reply as well as to get the offer of a high package 😅. I couldn't watch two video (components and interceptors) due to time shortage , but they too asked question on those 😅. I was then regretting If I would watch, I could answer properly, though I managed somehow! And end result is I achieved a clear concept on Angular and grabbed the offer :). Hope I will be able to connect with you in Linkedin 😀

What is preflight ?

[@NishaSingla]

A CORS preflight request is a CORS request that checks to see if the CORS protocol is understood and a server is aware using specific methods and headers. It is an OPTIONS request, using three HTTP request headers: Access-Control-Request-Method , Access-Control-Request-Headers , and the Origin header.
