Hydration for Angular Apps: Tips and Tricks for Optimal Performance

Introduction

Are you tired of losing your precious app state every time you reload or reopen your application? Fear not, for re-hydration is here to save the day!

Re-hydration, a process of restoring your application state through serialization, is a built-in feature in NgRx/Store. However, if you’re using a custom state management system, you’ll need to implement re-hydration yourself.

In this article, we’ll guide you through the process of creating a dedicated reducer method for re-hydration, allowing you to keep your state management organized and maintainable. Plus, with the added bonus of a bit of humor, you might even enjoy the process!
