How to track pending HTTP requests in angle 2

I want angular 1 $HTTP in angular 2 A substitute for pendingrequest or anything that follows the interceptor's global trace It is mainly used to display the load icon when making a call

Solution

I may just keep the icon state and observable hasn't returned yet

Example:

export class MyClass {
    private isLoaded = false;

    constructor(private myService: MyService){}

    ngOnInit(){
        this.myService.myServiceCall().subscribe(data => {
            console.log(data);
            this.isLoaded = true;
        });
    }

}

Then use * ngif. In the dialog box You can also consider using the asynchronous pipeline provided by angular for the following scenarios:
