1.2.0 • Public • Published


Version Documentation Maintenance License: MIT

React Native component that notifies if the user is active or not (i.e. when the app surface hasn't been touched for more than a certain amount of ms).

As of version 1.1.0, react-native-user-inactivity resets the timer also when the keyboard appears or disappears. If you want to avoid this behaviour, you can set the skipKeyboard property to true.

As of version 1.0.0, react-native-user-inactivity has been rebuilt as a functional component that uses the new React Hook API. Thanks to usetimeout-react-hook, react-native-user-inactivity supports timers different than the standard one (setTimeout). This has solved some of the most recurrent issues, such as #12, #16, #17.


npm install react-native-user-inactivity

If you are running a version of react < 17 you'll need to include the --legacy-peer-deps flag.

npm install react-native-user-inactivity --legacy-peer-deps

🔑 Key features

  • 🥇 supports generic timers (you're no longer constrained to setTimeout)
  • ⚠️ optional reset capability of the timer
  • super elastic behaviour thanks to the Hooks API
  • 💪 written in TypeScript
  • ✔️ the core logic of this component is delegated to usetimeout-react-hook, which has 100% code coverage

How to use

This package primarily exposes a single functional component, UserInactivity. The signature of the UserInactivity React props is the following:

interface UserInactivityProps<T = unknown> {
   * Number of milliseconds after which the view is considered inactive.
   * If it changed, the timer restarts and the view is considered active until
   * the new timer expires.
   * It defaults to 1000.
  timeForInactivity?: number;

   * If it's explicitly set to `true` after the component has already been initialized,
   * the timer restarts and the view is considered active until the new timer expires.
   * It defaults to true.
  isActive?: boolean;

   * Generic usetimeout-react-hook's TimeoutHandler implementation.
   * It defaults to the standard setTimeout/clearTimeout implementation.
   * See
  timeoutHandler?: TimeoutHandler<T>;

   * Children components to embed inside UserInactivity's View.
   * If any children component is pressed, `onAction` is called after
   * `timeForInactivity` milliseconds.
  children: React.ReactNode;

   * If set to true, the timer is not reset when the keyboard appears
   * or disappears.
  skipKeyboard?: boolean;

   * Optional custom style for UserInactivity's View.
   * It defaults to { flex: 1 }.
  style?: StyleProp<ViewStyle>;

   * Callback triggered anytime UserInactivity's View isn't touched for more than
   * `timeForInactivity` seconds.
   * It's `active` argument is true if and only if the View wasn't touched for more
   * than `timeForInactivity` milliseconds.
  onAction: (active: boolean) => void;

When a native timer is needed (in order to avoid issues such as #12, #16, #17) an implementation of usetimeout-react-hook's TimeoutHandler should be passed to the timeoutHandler prop. A default one (BackgroundTimer) is optionally provided: in order to use it you must:

  • manually run: npm i -S react-native-background-timer
  • manually link the native library: react-native link react-native-background-timer

In case of doubts, please refer to the official react-native-background-timer repository.

The default BackgroundTimer can be used like this:

import UserInactivity from 'react-native-user-inactivity';
import BackgroundTimer from 'react-native-user-inactivity/lib/BackgroundTimer';

export default () => {
  return (
      onAction={isActive => { console.log(isActive); }}
      style={{ flex: 1, paddingTop: '10%' }}

Warning: it seems that react-native-background-timer doesn't work properly with Android 10+ (#41). I'm currently unable to reproduce the problem, but help from the open-source community on this matter is certainly appreciated.


Since the component itself is written in TypeScript, your editor's intellisense system should automagically detect the typings file (even if you're using plain JS!), thus providing a better developer experience. In fact, autocomplete capabilities and warning should come for free as you're typing the props to pass to the UserInactivity component.

💪 Practical Example

import React, { useState } from 'react';
import { View, Text, TextInput, Button } from 'react-native';
import UserInactivity from 'react-native-user-inactivity';

export default () => {
  const [active, setActive] = useState(true);
  const [timer, setTimer] = useState(2000);

  return (
    <View style={{ flex: 1 }}>
        onAction={isActive => { setActive(isActive); }}
        style={{ flex: 1, paddingTop: '10%' }}
        <Button id="btn-1" title="1 Press this to simulate activity" />
        <Button id="btn-2" title="2 Press this to simulate activity" />
        <Text id="text-1" style={{ textAlign: 'center' }}>Type below to simulate activity</Text>
          style={{height: 40, borderColor: 'gray', borderWidth: 1}}
          onChange={() => { setActive(true); }}
          onChangeText={text => setTimer(Number.parseInt(text || 0, 10))}
      <View style={{ flex: 3, backgroundColor: '#fcfcaa', }}>
        <Text style={{ textAlign: 'center' }}>{active ? 'ACTIVE' : 'NOT ACTIVE'}</Text>
        <Button title="Manually set to Active" onPress={() => { setActive(true); }} />
