It makes use of the.Summary The recommended method to interact via a Http service is by creating an intermediate service which has the responsibly of communicating with the API and converting the raw data into one or more domain models.

    write better asynchronous code in your Angular 7/8 apps with an example using HttpClient for sending HTTP requests and RxJS Observables.But when you convert the Observable to a promise, the callback provided to the then method is executed one time no more.

    Promises were created to make less use of callbacks but then itself uses a callback function.

    RxJS provides the toPromise operator which converts an Observable to a promise so you can work with the HttpClient methods using promises instead of Observables.

    Note If you remember from the section on ES6 and TypeScript we can use promises by returning an instance of a Promise class.

    We call the get method which returns an Observable but thanks to toPromise we get a promise and we call the then method to send the API request and provide a callback that displays date once it's fetched.

    If you don't need to observe a source for a stream of data that comes in different points of time, you can use promises instead of Observables which need to be unsubscribed or otherwise will cause memory leaks and unexpected behaviors if not handled right.
