This project was generated with Angular CLI version 9.1.0.
This demo project shows how you can add http interceptor to your Angular project to intercept outgoing requests and incoming responses.
For outgoing requests, make your code easier to read and less redundent by appending the server and header information in the interceptor.
For incoming requests, check if received a 504 Gateway Timeout and attempt to retry 3 times with a 500 millisecond delay.
See my blog for an explanation of the code.
Run ng serve for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.
Run ng generate component component-name to generate a new component. You can also use ng generate directive|pipe|service|class|guard|interface|enum|module.
Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the --prod flag for a production build.
Run ng test to execute the unit tests via Karma.
Run ng e2e to execute the end-to-end tests via Protractor.
