Description

There are many types of state. In this course, Managing React State, you’ll learn how to effectively declare state to create rich, interactive React apps. First, you’ll discover eight ways to handle state in React apps. Next, you’ll explore how to manage each of these types of states including route state, component state, and refs in both function and class components. Finally, you’ll learn when to consider global state via context and third party state libraries.

Course Overview
[Autogenerated] Hi, I'm Cory House and welcome to my course managing React State. I'm the founder and principal consultant of React Yes, consulting dot com. React gaps aren't just read only their interactive, so a typical react up declares literally dozens of pieces of state and then react. There's a surprising number of options for effectively handling this state, including plane, state refs, context reducers, Web storage hooks and mawr. In this course, we're going to build a realistic online store using modern state management approaches. Some of the key topics that will cover include patterns for declaring, setting and reliably deriving state sharing data and logic between components. Managing, loading, air and form validation. State tracking on rendered state and server state and, most importantly, how to choose between these different state management approaches. By the end of this course, you'll know how to use a variety of react. State management approaches, and you'll understand when each makes sense, you'll be prepared to build complex interactive react APS using modern techniques before beginning the course. You should be familiar with react fundamentals such as function components, JSX and props. I hope you'll join me on this journey to learn modern react state management techniques with the Managing React State course at plural site
