Today, I'm very proud to share with you the release announcement of version 1.0.0 of my package filter-async-rxjs-pipe on npm! 🥳
This update contains version bumps for all dev and prod dependencies to avoid security risks. However, I noticed, that this package has 90 - 300 weekly downloads, so I want to declare it stable as it is now.
This package originated from a question on StackOverflow, asking if there is a filter operator for rxjs which accepts a promise in return. This would allow making network requests inside filter functions or using other async browser apis.
I took the suggestions from there (Shoutout to Brandon for the original answer!) and wrapped it into a neat little npm library.
This rxjs 6+ pipe accepts a predicate function which returns a Thenable for filtering. (e.g. any object with a 'then' method === Promise and custom promise implementations)
This rxjs 6+ pipe accepts a predicate function which returns an Observable for filtering.
Both of these functions have a parallel flag to indicate, that they should run the predicate function in parallel for each emitted event from the source observable. It should work, however, I currently have no valid test case for that.
So, if you have any idea, how to test this correctly, please file an issue here on my repo!
