Installation

Install the package by running:

npm install @iroomit/react-native-in-app-notification

or

yarn add @iroomit/react-native-in-app-notification

Usage

Getting Started

You must wrap the root of your app in your App.js or App.tsx file with <InAppNotificationProvider />:

...

import { InAppNotificationProvider } from '@iroomit/react-native-in-app-notification';

const App = () => {

    return (
        <InAppNotificationProvider>
            <View>
                ...
            </View>
        </InAppNotificationProvider>
    )
}

...

Use in Functional Components

To display a notification from any functional component within your application, you can use the useInAppNotification() hook to get access to the showNotification(...) and dismissAll() methods:

...

import { useInAppNotification } from '@iroomit/react-native-in-app-notification';

const MyButton = () => {
    const { showNotification } = useInAppNotification();

    return (
        <TouchableOpacity onPress={() => {

            showNotification("My Title", "My notification text can go here", "https://mydomain.com/myimage.png", {
                onPress: () => console.log('Notification pressed!')
            });
            
        }}>
            ...
        </TouchableOpacity>
    )
}

...

Use in Class Components

You can wrap your class component definition with the withInAppNotification(...) higher-order component function to access the inAppNotification prop that provides showNotification(...) and dismissAll() methods:

...
import React from 'react';
import { withInAppNotification } from '@iroomit/react-native-in-app-notification';

export default withInAppNotification(class MyButton extends React.Component {
    constructor(props) {
        super(props);
    }

    render() {

        return (
            <TouchableOpacity onPress={() => {

                this.props.inAppNotification.showNotification("My Title", "My notification text can go here", "https://mydomain.com/myimage.png", {
                    onPress: () => console.log('Notification pressed!')
                });
                
            }}>
                ...
            </TouchableOpacity>
        )
    }
});
...

API Reference

InAppNotificationProvider: Component

Props

• titleTextStyle (optional): A style prop that defines the text style for the notification title.
• messageTextStyle (optional): A style prop that defines the text style for the notification message.
• thumbnailStyle (optional): A style prop that defines the style for the notification thumbnail image.

showNotification(title: string, message: string, imgUrl?: string, options?: InAppNotificationOptions): Function

This function adds a notification to the queue to be shown. By default, one notification is shown every 3 seconds. If there are no more notifications in the queue, the last/only notification in the queue is shown for up to 9 seconds.

• title and message are required.
• If imgUrl is not provided, the image preview on the left of the notification is hidden.

InAppNotificationOptions

An optional object to further customize each individual notification. For now, just used to assign a callback for the onPress action.

• onPress (optional): Function

If onPress is not defined, then the notification shown will not be pressable.

dismissAll(): Function

This function immediately dismisses any visible notifications and clears the queue of any remaining notifications that were to be shown.

Collaboration

While this package is production-ready, we are open to collaboration on new features and bug fixes. We also intend on supporting various kinds of notification styles in the near future.
