Why doesn't .query() return a Promise?

I’ve asked this here https://github.com/apollographql/apollo-client/issues/2561#event-1343477916 and I was told that apollo-client itself returns a promise on .query() - why doesn’t apollo-angular do the same as apollo-client?

Here’s the question I asked in the apollo-client repo:

Just wanted to ask for the reasen why .query() does not return a Promise

I always end up calling .toPromise() because I don’t want to unsubscribe something that is executed once anyway.

And if there’s a good reason for it, does this mean, calling toPromise() is bad practice?

It’s angular integration, it means there are Observable that can be chained. The whole ecosystem is built on Observables instead of Promises.

Instead of calling .subscribe() you can just call .toPromise() and then it works as expected.
