GroupBy: RxJS' Secret Weapon

Thanks for joining Mike Ryan and I for GroupBy: RxJS’ Secret Weapon! We hope you learned a lot about the groupBy operator, as well as when to use exhaustMap, switchMap, and concatMap!

Here’s the video from RxJS Live 2019:

Here are the slides:

• GroupBy: RxJS’ Secret Weapon

And here is the sample code:

• rxjs-groupby-basic

There’s a branch for mergeMap, concatMap, and switchMap by themselves, as well as one for using groupBy and another to demonstrate how to extract a custom operator.
