Never thought about getting total count in hook like this. I have always used [performant count]( meteor add natestrauser:publish-performant-counts) for that, given the cost of count.
@StorytellerCZ The package you talk about is for publishing counts (reactive). @Floriferous is talking about a static, one-time count. Like when you would fetch data from an RPC.
An after fetch hook would be a good idea if you want to do this a lot, but it wouldn't be trivial for this package, since fetch is a cursor method and this hooks system currently only works for collection methods.
@sebakerckhof got it! I agree, I think this is a bit out of scope. Might be a good idea to extend the fetch method or create a new one where you would call .countFetch()
and it would return an object: { data: [...], count: 15 }
.
Maybe this is already possible with the current hooks, but I'm not entirely sure:
I'd like all of our limited/skipped mongo queries to also return the total count, without having to manually add this everywhere. This makes it very easy on the front-end to display counts, display a "load more" button (and stop showing it, once you've loaded everything), or simply display a table pagination widget with the total amount of pages.
I believe the place to do this would be in a
after.fetch
hook: here's roughly what I'd want it to do:If someone knows of another way to achieve this, or improve the implementation details (e.g. allow toggling this behavio on/off, depending on if you need the count), I'd be happy to learn about it :)
