Use async functions instead of promises #447
Description
Overview of the feature request
Use async/await instead of promises for more succinct code.
For example, instead of the following JHipster-generated code
this.rideService()
.retrieve(paginationQuery)
.then(
res => {
this.rides = res.data;
this.totalItems = Number(res.headers['x-total-count']);
this.queryCount = this.totalItems;
this.isFetching = false;
},
err => {
this.isFetching = false;
}
);do this:
try {
const res = await this.rideService().retrieve(paginationQuery);
this.rides = res.data;
this.totalItems = Number(res.headers['x-total-count']);
this.queryCount = this.totalItems;
} finally {
this.isFetching = false;
}Note that I've left out catch for purely aesthetic reasons - it is still actually required.
Motivation for or Use Case
Quoting Google Developers async functions primer:
Async functions are [...] quite frankly marvelous. They allow you to write promise-based code as if it were synchronous, but without blocking the main thread. They make your asynchronous code less "clever" and more readable.
