Building Your First Angular HTTP Interceptor

Angular's HTTP Interceptors are a super powerful way to level up the way you interact with APIs and backends. You can add tokens, logging, handle failures more gracefully, and so much more.

In this video we create our first HTTP Interceptor that appends a token to every API request we make.

I was struggling with interceptors, then I found this video simply just explaining what interceptor is. Thanks for such a straight forward explanation!

one week fighting with this f..in interceptors 😆😆 thank you so much! couldn´t find any documentation on how to add it as a provider correctly.

Interesting .. seems similar to service workers (sort of) except SWs don't talk to the UI and live 'outside' the app, whereas interceptors are on the 'inside'. Thanks for the tip, will explore.

Hello Stephen and thanks for a great tutorial. I hade a question about this interceptor: could it checks for lack of pair of key-value in Params and in that case act upon it?
