E066 - NgRx Effects Best Practices

Show Summary:

We're back from our summer break and we're releasing a fresh episode of The Angular Show with a special guest, Mike Ryan, a Principal Architect with LiveLoveApp. Mike is a co-creator and member of the NgRx core team, a contributor to open-source, and a Google Developer Expert in Angular. Mike joins our panelists Aaron Frosts, Jennifer Wadella, and Brian Love, to chat about NgRx Effects best practices.

NgRx is the defacto standard state management solution for Angular. While the core state module is highly inspired by Redux, the Effects library is unique to NgRx, and one of the best features of NgRx (in our humble opinion). NgRx Effects enable developers to perform side effects, like fetching data from an API, in an elegant and efficient manner. But, effects can also be tricky, hard to test, and sometimes it's not clear what RxJS operator is best suited for an effect.

In this episode, we learn from Mike the best practices of using NgRx Effects, how to make them simpler, more maintainable, and easier to test. Plus, there are a handful of simple tips that you can walk away with and immediately improve the performance of your Angular application that is using NgRx Effects. Plus, if you've ever been unsure about which higher-order mapping operator (ya know, those somethingMap() ones) to use with an effect, Mike will break it all down for you in a straightforward way. This is an episode of The Angular Show that you do _not_ want to miss.
