React & Immer | Immer

Article Summary

This article discusses the use of Immer in React to simplify the updating of component state. It provides examples of using Immer with useState, useImmer, useReducer, and useImmerReducer, as well as how to apply Immer with Redux.

React & Immer

The article starts by introducing the use of Immer in React to simplify state updates. It explains that the useState hook assumes that any state stored in it is immutable, and Immer can greatly simplify the deep updating of component state. The example code demonstrates how to use produce and useState to achieve this.

useImmer

The article then discusses the use of useImmer, which simplifies state updates by wrapping them in the produce function. It provides an example code that shows how to use useImmer with an array of todos.

useReducer + Immer

Next, the article explains how useReducer can be combined with Immer to simplify state updates. It provides an example code that demonstrates the integration of useReducer and produce to handle toggle and add actions.

useImmerReducer

The article also discusses the use of useImmerReducer, which further simplifies state updates by combining useReducer and Immer. It provides an example code that shows how to use useImmerReducer to handle toggle and add actions.

Redux + Immer

Finally, the article mentions the use of Redux with Immer. It explains that by wrapping the reducer function with produce, it is safe to modify the draft state. An example code is provided to demonstrate how to use Immer with Redux.
