Make loadable.preload() return a promise

🚀 Feature Proposal

Make loadable.preload() return a promise

Motivation

I'm implementing a "prefetcher" that will, depending on some conditions, request a bunch of known loadable components from an "index" object whose keys are strings and values loadable-components. At some point, I call preload on a bunch of these and I need a way to await on the loading promise of all components, seems like the only change necessary is to add a return statement at the end of the preload() function.

Pitch

To be honest, I kind of expected this to work, I was surprised preload() returns undefined.

There is a long discussion, and the solution you are looking for - #226

Hello @luishdz1010, .preload() is a "preload" action so it can't return a promise. If we expose this API, it will be under .load(). But I think it is not the good approach to take, with "Suspense" you will not be able to wait for component to be loaded this way. I suggest you to create your own load method if you want to do it. I prefer to wait for Suspense before adding this kind of API.

My bad for not looking hard enough 🤦‍♂️, thanks for the quick reply.
