Tera idle timer5/18/2023 We made use of the exposed properties and methods to add an idle timer to our React application.Īll of the code in this article is available on GitHub. In this tutorial, we implemented an idle timer using the react-idle-timer package, which handles the binding and unbinding of keyboard and mouse events for us. It is equally important to provide appropriate timeout notifications to the user to avoid disrupting their workflow. When adding an idle timer, it is important to carefully consider the duration of the timeout based on the user information’s level of risk. Implementing an idle timer can improve the security of your web application. The video below demonstrates app behavior with an idle timer implemented. When the user clicks Sign out now, the user is logged out and the idle timer is destroyed.When the user clicks Stay signed in, the idle timer is reset and the user stays logged in.When the user clicks the C *lose* button, the idle timer is reset and the user stays logged in.However, when they interact with the modal, their interactions produce the following results: If the user does not interact with the prompt, then they’ll be logged out automatically. When a user stays idle for half of the specified time, we’ll display a prompt. The idle timer resets when the Stay signed in button is clicked. In this code, we create an instance of the useIdle Hook, which in turn automatically starts the idle timer for us. The HomePage will contain a displayed text and a modal that will only display when the user is idle. Import HomePage from './components/Homepage'Ĭonst = useState(false) Import NavigationBar from './components/NavigationBar' Import AuthContext from "./context/AuthContext" The App.js file displays the homepage and login page based on the authentication status. Our login page Our homepage when we’re logged in You will create a simple web application with a HomePage and a Login page, as shown below. Then, open the React application in your favorite code editor. In your terminal, create a new React application and start the development server using the commands below: npx create-react-app idle-timer-react User idleness is then toggled based on the last time the bound events were triggered. The react-idle-timer package binds all of these events to a DOM element by adding an event listener for each. There are also two deprecated events, DOMMouseScroll and mousewheel, which we won‘t focus on in this post. MSPointerMove – Fires when a pointer changes coordinates.MSPointerDown – Fires when a pointer becomes active.visibilitychange – Fires at the document when the contents of its tab have become visible or have been hidden.touchmove – Fires when one or more touch points are moved along the touch surface.touchstart – Fires when one or more touch points are placed on the touch surface.mousedown – Fires at an element when a button on a pointing device is pressed.wheel – Fires when the wheel of a pointing device is rotated.mousemove – Fires when a pointing device is moved.The react-idle-timer package makes use of the following events to detect user activity: The DOM API provides mouse and keyboard events that can be used for idle detection. Events for idle detection in react-idle-timerĮvents for idle detection in react-idle-timer.We’ll use the react-idle-timer package to detect and respond to the user’s idleness. In this article, we’ll learn how to implement an idle timeout in your React application. This logs the user out when idle and prevents unnecessary backend requests. Implementing an idle session timeout to sign a user out of their current session is one way to enhance the platform’s security.įor example, with applications that make API calls every 30 seconds, it is necessary to implement an idle timeout to improve the app’s performance. As a developer, you need to guard the end user against intruders. When building websites that contain highly confidential user information, the platform’s security is a major concern. An idle timer is used to sign out a user after checking whether they’ve been inactive for a specified duration. How to make an idle timer for your React appĪn idle timer is one way to add an additional layer of security to your web application.
