Practice makes perfect - when it comes to RxJS

Stop memorizing RxJS operators. Start building a reactive mindset to master complex async logic and build UIs from scratch.

Practice makes perfect - when it comes to RxJS
#1about 5 minutes

Developing a reactive mindset for RxJS

Learning RxJS is like learning a new language, where practicing to develop a reactive mindset is more crucial than memorizing every operator.

#2about 6 minutes

Building a swipe gesture for a carousel

Implement a swipe gesture by merging mouse and touch events, using `switchMap` to track movement, and `takeUntil` to detect the end of the gesture.

#3about 3 minutes

Adding keyboard navigation to the carousel

Use `fromEvent` on the document to listen for keydown events, then filter for specific keys and map them to navigation actions.

#4about 4 minutes

Creating an auto-play timer with reset logic

Implement an auto-advancing carousel timer using `interval`, which resets on user interaction with `takeUntil` and restarts with `repeatWhen`.

#5about 6 minutes

Recapping the reactive carousel implementation

A step-by-step review of how observables for swipe, keyboard, and timer events were composed and merged to create a fully functional carousel.

#6about 5 minutes

Exploring improved typings in RxJS 7

RxJS 7 introduces better type inference for union types in conditional logic, `concat`, `reduce`, and when filtering with the `Boolean` constructor.

#7about 3 minutes

New animation and composition operators in RxJS 7

Discover the new `animationFrame` observable for creating smooth animations and the `concatWith` pipeable operator for improved code readability.

#8about 2 minutes

Practice examples for mastering RxJS

To solidify your reactive mindset, try building common UI features like drag-and-drop, typeahead search, or long polling with RxJS.
