RxJS: Turn a Stream of Objects into an Object of Streams
Hi, fellow streamer! Today I want to share a JS/TS package that allows you to access props of objects on Observables:
tl;dr: github.com/kosich/rxjs-proxify 📦
A simple use case:
The package has good TypeScript support, so all props are intelli-sensed by cats, dogs, and IDEs:
It’s also possible to call methods on values, e.g.:
And you can apply RxJS operators at any depth:
The package uses Proxies under the hood, recursively applying it to sub-properties and method results, so the chain can be indefinitely deep. And you can apply
.pipe at any time!
🎹 Try it
You can install it via
npm i rxjs-proxifyOr test it online: stackblitz.com/edit/rxjs-proxify-repl
The source code and more examples are available on github repo:
Thank you for reading this article!
Stay reactive and have a nice day 🙂
