I have this function that I need to move from AngularJs to VueJs and it has me stumped! Any help would be appreciated :)
items = {
one: {...details here...},
two: {},
}
AngularJs
var promises = [];
var deferred = $q.defer();
angular.forEach(items, function(details) {
promises.push(details.promise);
});
$q.all(promises).finally(function() {
deferred.resolve();
});
return deferred.promise;
What I have in VueJs so far
let promises = [];
for (let [name, details] of Object.entries(items)) {
promises.push(new Promise((resolve) => {resolve(details)}));
}
return Promise.all(promises);
Thank you!
CodePudding user response:
There is no need for new Promise
because Promise.all
allows for non-promise values.
For a promise that resolves with undefined
(this is what a deferred does) when all object values are settled (i.e. resolved or rejected), it's:
Promise.all(Objects.values(items).map(({ promise }) => promise))
.then(() => {}) // if it's necessary to resolve with undefined
.catch(() => {}) // if it's necessary to not reject
If all values aren't promises, there is no need for Promise.all
at all.
