React Native Push Notification Popup

Features

• Support "pan" gesture
• Support "onPress" gesture feedback
• Written in pure-JS using official react-native Animation package
  • Which means it supports all Expo/CRNA apps
• Support iPhone X, XS, Max (yeah that notch)
• Support Android native "elevation"

Motivations

Blog post

1. In some apps, you may just want to display reminders to user, without going through those troublesome push notification setups
2. Expo/CNRA apps cannot display push notification while app is in foreground
3. Even if you eject, you still need to configure iOS and Android separately with native codes

This package is here to help. Just show your own notification popup to your users!

Installation

# yarn, recommended
yarn add react-native-push-notification-popup

# or npm
npm install react-native-push-notification-popup --save

Usage

Declare Component

Put it in a wrapper component. (Maybe where you handle your incoming push notifications)

import NotificationPopup from 'react-native-push-notification-popup';

class MyComponent extends React.Component {
  render() {
    return (
      <View style={styles.container}>
        <MaybeYourNavigator />
        <NotificationPopup ref={ref => this.popup = ref} />
      </View>
    );
  }
// ...

IMPORTANT: Remember to put it on the bottom of other components, because React render from back to front in order of declaration. We do not use zIndex becuase it is problematic on Android.

Optional: Customize your popup

// Render function
const renderCustomPopup = ({ appIconSource, appTitle, timeText, title, body }) => (
  <View>
    <Text>{title}</Text>
    <Text>{body}</Text>
    <Button title='My button' onPress={() => console.log('Popup button onPress!')} />
  </View>
);

class MyComponent extends React.Component {
  render() {
      return (
        <View style={styles.container}>
          <NotificationPopup
            ref={ref => this.popup = ref}
            renderPopupContent={renderCustomPopup}
            shouldChildHandleResponderStart={true}
            shouldChildHandleResponderMove={true}
            isSkipStatusBarPadding={true} />
        </View>
      );
    }
// ...

Show it!

componentDidMount() {
  this.popup.show({
    onPress: function() {console.log('Pressed')},
    appIconSource: require('./assets/icon.jpg'),
    appTitle: 'Some App',
    timeText: 'Now',
    title: 'Hello World',
    body: 'This is a sample message.\nTesting emoji 😀',
    slideOutTime: 5000
  });
}
