Order of HttpInterceptors

Question

I have a application that uses a plugin that register a HttpInterceptor.

Now I need to create my own interceptor that need to be run before the other interceptor because it will change some values, in localStorage, that the other interceptor uses.

How can I influence in the execution order when registering a new HttpInterceptor?

Answer 1

You cannot set interceptors order. Interceptors are chained in order they are declared.

You will have write your own super interceptor that will allow to append child interceptors with some ordering logic.

So what you're saying is that you can set interceptors order by declaring them in a specific order. – Confirm

caso um dos interceptors esteja em um modulo e outro nao como fica essa ordem – Chafe

Please delete your answer, this is not true. – Martensite

This answer is true, if OP need to change the order dynamically. – Cambrian

Answer 2

https://angular.io/guide/http-intercept-requests-and-responses#interceptor-order

Angular applies interceptors in the order that you provide them. If you provide interceptors A, then B, then C, requests flow in A->B->C and responses flow out C->B->A.
