react-native-notifier

Fast and simple in-app notifications for React Native

Requirements

This library uses react-native-gesture-handler, a perfect library for swipes, and other gesture events.

If you are using react-navigation then you already have gesture-handler installed. If you don't, check Getting Started guide to install it: https://software-mansion.github.io/react-native-gesture-handler/docs/getting-started.html

Installation

yarn add react-native-notifier

Or

npm install --save react-native-notifier

Usage

Wrap your app with NotifierWrapper

import { NotifierWrapper } from 'react-native-notifier';

const App = () => (
  <NotifierWrapper>
    <Navigation />
  </NotifierWrapper>
);

Then call Notifier.showNotification() anywhere in code

import { Notifier, Easing } from 'react-native-notifier';

Notifier.showNotification({
  title: 'John Doe',
  description: 'Hello! Can you help me with notifications?',
  duration: 0,
  showAnimationDuration: 800,
  showEasing: Easing.bounce,
  onHidden: () => console.log('Hidden'),
  onPress: () => console.log('Press'),
  hideOnPress: false,
});

---

Or add NotifierRoot at end of your App.js component. With this approach you can show notification using reference to the NotifierRoot.

Note that NotifierRoot should be the last component to display notifications correctly. Notifier.showNotification is also available.

import { NotifierRoot } from 'react-native-notifier';

function App() {
  const notifierRef = useRef();
  return (
    <>
      <Button
        title="Show Notification"
        onPress={() => notifierRef.current?.showNotification({ title: 'Using refs' })}
      />
      <NotifierRoot ref={notifierRef} />
    </>
  );
}

All props passed to NotifierWrapper or NotifierRoot will be used as default params of showNotification function. This can be useful to set default Component param.

hideNotification

Notifier.hideNotification(onHiddenCallback?: Function);

Hide notification and run callback function when notification completely hidden.

Queue Mode

Queue mode is used to define the order in which the notification appears in case other notifications are being displayed at the moment.

For example, if you have some important information like chat messages and you want the user to see all the notifications, then you can use standby mode. Or if you want to display something like an error message, then you can use reset mode.

By default, reset mode is used, which means every new notification clears the queue and gets displayed immediately.

In most cases, you will probably use only reset or standby modes.

All possible modes:

Mode	Effect
reset	Clear notification queue and immediately display the new notification. Used by default.
standby	Add notification to the end of the queue.
next	Put notification in the first place in the queue. Will be shown right after the current notification disappears.
immediate	Similar to next, but also it will hide currently displayed notification.

Components

Currently, there are 2 components out of the box. If none of them fits your needs, then you can easily create your Custom Component.

NotifierComponents.Notification

Perfect for something like chat messages and notifications like "Someone left a comment". This component is used by default.

import { Notifier, NotifierComponents } from 'react-native-notifier';

Notifier.showNotification({
  title: 'Check this image!',
  description: 'Cool, right?',
  Component: NotifierComponents.Notification,
  componentProps: {
    imageSource: require('./react.jpg'),
  },
});

Available params:

Name	Type	Default	Description
title	String	null	Title of notification.
description	String	null	Description of notification.
componentProps.titleStyle	TextStyle	null	The style to use for rendering title.
componentProps.descriptionStyle	TextStyle	null	The style to use for rendering description.
componentProps.imageSource	Object	null	Passed to <Image /> as source param.
componentProps.imageStyle	ImageStyle	null	The style to use for rendering image.
componentProps.ContainerComponent	Component	SafeAreaView	A container of the component. Set it in case you use different SafeAreaView than the standard
componentProps.maxTitleLines	number	null	The maximum number of lines to use for rendering title.
componentProps.maxDescriptionLines	number	null	The maximum number of lines to use for rendering description.

NotifierComponents.Alert

Perfect to use as a system alerts, like "Something went wrong" or "Operation was succeed".

import { Notifier, NotifierComponents } from 'react-native-notifier';

Notifier.showNotification({
  title: 'The request was failed',
  description: 'Check your internet connection, please',
  Component: NotifierComponents.Alert,
  componentProps: {
    alertType: 'error',
  },
});

Available params:

Name	Type	Default	Description
title	String	null	Title of notification.
description	String	null	Description of notification.
componentProps.titleStyle	TextStyle	null	The style to use for rendering title.
componentProps.descriptionStyle	TextStyle	null	The style to use for rendering description.
componentProps.alertType	String	'success'	Background color will be changed depending on the type. Available values: error(red), success(green), warn(orange) and info(blue).
componentProps.backgroundColor	String	null	While the background of the alert depends on alertType, you can also set the other color you want.
componentProps.textColor	String	'white'	Color of title and description.
componentProps.ContainerComponent	Component	SafeAreaView	A container of the component. Set it in case you use different SafeAreaView than the standard
componentProps.maxTitleLines	number	null	The maximum number of lines to use for rendering title.
componentProps.maxDescriptionLines	number	null	The maximum number of lines to use for rendering description.

Custom Component

To customize look of the notification you can pass your own Component to showNotification function.

This makes customization much simpler than passing "style" params. With custom components you can make notification look exactly like you want.

This component will receive props title, description and anything else that you pass to componentProps object when calling showNotification.

Example

import React from 'react';
import { StyleSheet, View, Text, SafeAreaView } from 'react-native';

const styles = StyleSheet.create({
  safeArea: {
    backgroundColor: 'orange',
  },
  container: {
    padding: 20,
  },
  title: { color: 'white', fontWeight: 'bold' },
  description: { color: 'white' },
});

const CustomComponent = ({ title, description }) => (
  <SafeAreaView style={styles.safeArea}>
    <View style={styles.container}>
      <Text style={styles.title}>{title}</Text>
      <Text style={styles.description}>{description}</Text>
    </View>
  </SafeAreaView>
);

// ...

// Then show notification with the component

Notifier.showNotification({
  title: 'Custom',
  description: 'Example of custom component',
  Component: CustomComponent,
});
