The "AsyncAlert" library is a powerful tool that allows developers to display alerts or modals asynchronously in their React Native applications. With a simple and intuitive API, it provides a seamless way to handle user interactions and gather responses from alert dialogs.
The library includes the AlertProvider
component, which serves as a context provider for managing the display of alerts. By wrapping your application with AlertProvider
, you gain access to the useShowAlert
hook, which provides a function for showing alerts.
The showAlert
function, provided by the library, enables you to show alerts dynamically by passing in various options such as the title, text, and additional alert data. It returns a promise that resolves to a boolean value indicating the user's response to the alert.
Install react-native-async-alert with npm
npm install react-native-async-alert
with yarn
yarn add react-native-async-alert
Using default alert
Wrap your application with <AlertProvider>
in top-level files like index.js
or App.js
.
import {AlertProvider} from 'react-native-async-alert';
import {useShowAlert} from 'react-native-async-alert';
function App() {
return (
<AlertProvider>
<SafeAreaView>
<RemainingContent />
</SafeAreaView>
</AlertProvider>
);
}
import React from 'react';
import Button from 'react-native';
import {useShowAlert} from 'react-native-async-alert';
function ExampleScreen() {
const showAlert = useShowAlert();
return (
...
<Button title={'Show alert'} onPress={async () => {
const result = await showAlert({
title: 'Title',
text: 'text' // (or) <Text>Text component</Text>,
});
console.log(result);
}}/>
...
);
}
Creating your custom alert
You need to pass your custom alert to the renderAlert
function. Make sure to use the props.
import {AlertProvider} from 'react-native-async-alert';
const renderAlert = ({alertData, visible, hideCancel, text, title, onEvent, onPressCancel, onPressOk}) => {
return (
<SomeCustomAlert
title={title}
text={text}
onClose={onPressCancel}
onOk={onPressOk}
isAlertVisible={!!visible}
hideCancel={hideCancel}
footerContent={alertData?.footerContent} // We can use alert data for any type of data.
/>
);
};
function App() {
return (
<AlertProvider renderAlert={renderAlert}>
<SafeAreaView>
<RemainingContent />
</SafeAreaView>
</AlertProvider>
);
}
Then show the alert simply like below
import React from 'react';
import Button from 'react-native';
import {useShowAlert} from 'react-native-async-alert';
function ExampleScreen() {
const showAlert = useShowAlert();
return (
...
<Button title={'Show alert'} onPress={async () => {
const isClickedOk = await showAlert({
title: "Title",
text: "Text",
alertData: {
footerContent: <Text>Some Content</Text>
}
});
console.log(isClickedOk);
}}/>
...
);
}
