What’s New in RxJS v6.5
RxJS version 6.5.0 is now available. This post highlights the latest features and improvements in this version.
New Fetch Observable
RxJS now provides built-in support for using the native JS fetch API, including the ability to abort requests with AbortController baked-in.
forkJoin Improvements
This is one of my favorites. The forkJoin observable now takes a dictionary of sources:
Moreover, there is one deprecation — forkJoin(a, b, c, d) should no longer be used; Instead, pass an array such as forkJoin([a, b, c, d]).
Partition Observable
The current partition operator is deprecated in favor of a new creation observable, named partition.
The partition observable splits the source observable into two observables, one for values which satisfy the given predicate, and the other for values which don’t.
combineLatest Deprecation
This version deprecates all combineLatest signatures except combineLatest([a, b, c]) . You can read the reason for this change here.
Schedulers
Add the scheduled creation function to create a scheduled observable of values. The scheduled versions of from, range, et al. have been deprecated.
