state management

I encountered a problem while working on a project that involved a React form and how browser autofill interacts with it. Browser autofill automatically populates username/password fields when you have previously entered the information. This was causing an issue for me. Specifically, I observed this problem on Chrome and Firefox, but it could potentially occur on any browser. The form was a basic form built with the useState hook. Here’s an example of the email field:...

Redux is a popular state management library that is commonly used with React applications, although it can be used with other technologies as well. This guide will provide a simple and easy-to-follow overview of Redux and how to use it effectively. Why you need Redux Redux provides a way to manage the state of your application by moving it to an external global store. While React has its own method for managing state, Redux becomes necessary for complex applications where you find yourself moving state up and down the component tree using props....

Introduction State management is a crucial aspect of every application, especially in React. While hooks like useState() and prop passing can take us quite far, complex scenarios often call for a dedicated state management library. One such library I’ve come to appreciate is the easy-peasy library, built on top of Redux. With its simplified approach to handling state, it allows for cleaner and more manageable code. Installation To start using easy-peasy, simply install it using the following npm command:...

In the world of React, immutability is a significant concept that plays a crucial role in the development process. Whether you agree with it or not, React and its ecosystem strongly encourage the use of immutability. It is essential to understand why immutability is so important and the implications it has. In programming, immutability refers to a variable whose value cannot be changed once it is created. You might not realize it, but you are already using immutable variables when working with strings....

The React Context API is a powerful tool for managing state in your React applications. It allows you to pass state across different components without the need for manual prop drilling. This API simplifies the process of state management and can be used as an alternative to libraries like Redux. To understand how the Context API works, you first need to create a context using the React.createContext() function: const { Provider, Consumer } = React....

In this blog post, we will discuss how to interact with the state of your React components. The state is a crucial part of managing component data and handling user interactions. Setting the Default State To set the default state of a component, you need to initialize this.state in the constructor. For example, let’s consider a BlogPostExcerpt component with a clicked state: class BlogPostExcerpt extends Component { constructor(props) { super(props); this....

Discover the benefits and implementation of the useReducer React hook! Ever since the introduction of hooks in React, I have found them to be incredibly useful in several projects. They offer a more streamlined approach to writing code, making it feel like “real” JavaScript. By eliminating the need for class-based components, functional components can now handle state management effectively. For those who are new to hooks, I recommend checking out my introductory guide to React hooks here....

In this tutorial, we will explore the basics of Vuex, which is the official state management library for Vue.js. We will discuss the reasons why you should use Vuex and how to create a Vuex store. Additionally, we will go through a simple use case to understand how Vuex works. Introduction to Vuex Vuex is a state management library for Vue.js that allows you to share data across components in your application....
