User activity timer component

React Idle Timer

⚡️ Support for React 16
🚀 Support for Isomorphic React

Latest News

Version 4.2.0 brings typescript support and dynamic event binding to IdleTimer:

☝️ Events will now dynamically unbind when they are not needed (pause(), stopOnIdle) and bound when they are needed (resume(), reset(), startOnMount). If onAction is set, events will never be unbound.

✌️ Added a typescript type definition file that will be maintained alongside this library. It requires that you have the react type definitions installed.

For the full patch notes please refer to the CHANGELOG

Installation

yarn add react-idle-timer or npm install react-idle-timer --save

Usage

Run yarn example to build and run the example example. The example is a create-react-app project. IdleTimer is implemented in the App Component.

import React, { Component } from 'react'
import IdleTimer from 'react-idle-timer'
import App from './App'

export default class YourApp extends Component {
  constructor(props) {
    super(props)
    this.idleTimer = null
    this.onAction = this._onAction.bind(this)
    this.onActive = this._onActive.bind(this)
    this.onIdle = this._onIdle.bind(this)
  }

  render() {
    return (
      <div>
        <IdleTimer
          ref={ref => { this.idleTimer = ref }}
          element={document}
		  onActive={this.onActive}
          onIdle={this.onIdle}
          onAction={this.onAction}
		  debounce={250}
          timeout={1000 * 60 * 15} />
		{/* your app here */}
      </div>
    )
  }

  _onAction(e) {
    console.log('user did something', e)
  }

  _onActive(e) {
    console.log('user is active', e)
    console.log('time remaining', this.idleTimer.getRemainingTime())
  }

  _onIdle(e) {
    console.log('user is idle', e)
    console.log('last active', this.idleTimer.getLastActiveTime())
  }
}

Migration from v3 to v4

There are a few breaking changes in version 4:

• Although still capable of rendering children, as of version 4 we dont pass children to IdleTimer. Unless you are really good with shouldComponentUpdate you should avoid using IdleTimer as a wrapper component.
• The property startOnLoad has been renamed to startOnMount in order to make more sense in a React context.
• The property activeAction has been renamed to onActive.
• The property idleAction has been renamed to onIdle.

Documentation

To build the source code generated html docs run yarn docs and open docs/index.html in any browser. A markdown version is available here.

Default Events

These events are bound by default:

• mousemove
• keydown
• wheel
• DOMMouseScroll
• mouseWheel
• mousedown
• touchstart
• touchmove
• MSPointerDown
• MSPointerMove

Props

• timeout {Number} - Idle timeout in milliseconds.
• events {Array} - Events to bind. See default events for list of defaults.
• onIdle {Function} - Function to call when user is now idle.
• onActive {Function} - Function to call when user is no longer idle.
• onAction {Function} - Function to call on user action.
• debounce {Number} - Debounce the onAction function with delay in milliseconds. Defaults to 0. Cannot be set if throttle is set.
• throttle {Number} - Throttle the onAction function with delay in milliseconds. Defaults to 0. Cannot be set if debounce is set.
• element {Object} - Defaults to document, may pass a ref to another element.
• startOnMount {Boolean} - Start the timer when the component mounts. Defaults to true. Set to false to wait for user action before starting timer.
• stopOnIdle {Boolean} - Stop the timer when user goes idle. Defaults to false. If set to true you will need to manually call reset() to restart the timer.
• passive {Boolean} - Bind events in passive mode. Defaults to true.
• capture {Boolean} - Bind events in capture mode. Defaults to true.

Methods

• reset() {Void} - Resets the idleTimer
• pause() {Void} - Pauses the idleTimer
• resume() {Void} - Resumes a paused idleTimer
• getRemainingTime() {Number} - Returns the remaining time in milliseconds
• getElapsedTime() {Number} - Returns the elapsed time in milliseconds
• getLastActiveTime() {Number} - Returns the Timestamp the user was last active
• isIdle() {Boolean} - Returns whether or not user is idle
