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.

Here’s an example of the email field:...

When working on a menu that displays a list of items, each with its own icon, you may come across the need to dynamically choose which component to render based on certain conditions. In this blog post, we’ll explore different approaches to achieve this in React. Hardcoding Components in the Menu Initially, you might hardcode the components directly in the menu array. For example: const menu = [ { title: 'Home', icon: <HomeIcon className="mr-3 ml-1 h-5 w-5" /> }, { title: 'Notifications', icon: <BellIcon className="mr-3 ml-1 h-5 w-5" /> }, { title: 'Profile', icon: <UserIcon className="mr-3 ml-1 h-5 w-5" /> } ]; This approach works well if the components remain the same throughout the application....

In a React application, managing events is made easy with React’s built-in event handling system. Say goodbye to using addEventListener! In this article, we will explore how to interact with events in React. Event Handling in React Event handling in React is similar to handling events in plain old JavaScript, with a few key differences. Let’s consider the following example from a previous article about managing state in React: const CurrencySwitcher = props => { return ( <button onClick={props....

Learn the best way to reference a DOM element in React React is an excellent framework for abstracting the DOM when building applications. However, there may be situations where you need to access the actual DOM element represented by a React component. This could be because you need to integrate a library that interacts directly with the DOM, call a DOM API, or focus on a specific element. To begin, it’s important to ensure that you have explored all other options before resorting to accessing the DOM directly....

When working with forms in React, it is often necessary to obtain the value of a specific form field. This can be helpful, for instance, when a user clicks a button and you need to access the input data. In this article, we will explore how to retrieve the value of an input element in React. To achieve this, we can make use of React hooks. Hooks allow us to manage state in functional components....
