Requirements

• 2.x versions require react-native-reanimated 3.x.
• If your project does not use Reanimated, you can use react-native-alert-queue@1.x.

Install RN Reanimated following their official guide.

Installation

npm install react-native-alert-queue
# or
yarn add react-native-alert-queue

Usage

⚡ Full working examples available! Explore the example app here to see all features in action.

Basic Setup

First, add the AlertContainer to your app:

import { AlertContainer } from 'react-native-alert-queue';

function App() {
  return (
    <View>
      {/* Your app content */}
      <AlertContainer />
    </View>
  );
}

Showing Alerts

Any where in your app you can show alerts by using the alert object:

import { alert } from 'react-native-alert-queue';

// Basic alert
alert.show({
  title: 'Hello',
  message: 'I am an alert',
});

// Success alert
alert.success({
  message: 'Operation successful',
});

// Error alert
alert.error(new Error('Something went wrong'));

// Confirm dialog
const result = await alert.confirm({
  message: 'Are you sure you want to proceed?',
});

Alert Types

Basic Alert

alert.show({
  title: 'Custom Alert',
  message: 'This is a custom alert',
  buttons: [
    {
      text: 'OK!',
      onPress: () => console.log('OK pressed'),
    },
  ],
});

Success Alert

alert.success({
  message: 'Operation completed successfully',
});

Error Alert

alert.error(new Error('Operation failed'));

Confirm Dialog

const result = await alert.confirm({
  message: 'Are you sure you want to proceed?',
});

Confetti

alert.show({
  message: 'Welcome to the app!',
  confetti: true,
});

alert.show({
  title: 'Congratulations!',
  message: 'You are a winner!',
  confetti: {
    colors: ['#4CAF50', '#8BC34A', '#CDDC39', '#81C784', '#A5D6A7', '#C8E6C9'],
    numberOfPieces: 200,
    pieceDimensions: {
      height: 10,
      width: 30,
    },
  },
});

Confetti can be used with any alert type. Also, you can customize the confetti appearance globally in the config.

Advanced Features

Custom Helper Functions

You can create your own helper functions to simplify common alert patterns in your app:

const transactionCompletedAlert = (amount: string) =>
  alert.show({
    title: 'Transaction Complete',
    message: `Successfully transferred ${amount}`,
    icon: SuccessIcon,
    buttons: [
      {
        text: 'View Details',
        onPress: () => navigateToTransactionDetails(),
      },
      {
        text: 'Done',
      },
    ],
  });

// Create a custom error alert for network issues
const networkErrorAlert = (retryCallback: () => void) =>
  alert.show({
    title: 'Network Error',
    message: 'Network connection lost',
    icon: NetworkErrorIcon,
    buttons: [
      {
        text: 'Retry',
        onPress: retryCallback,
      },
      {
        text: 'Cancel',
      },
    ],
  });

// Usage
await transactionCompletedAlert('$100.00');

networkErrorAlert(() => fetchData());

Custom Rendering

alert.show({
  title: 'Custom Alert',
  message: 'This alert has custom rendering',
  renderTitle: ({ style, text }) => (
    <Text style={[style, { color: 'red' }]}>{text}</Text>
  ),
  renderMessage: ({ style, text }) => (
    <Text style={[style, { fontSize: 16 }]}>{text}</Text>
  ),
  renderButton: (props) => (
    <TouchableOpacity
      style={[styles.button, props.disabled && styles.disabled]}
      onPress={props.onPress}
      disabled={props.disabled}
    >
      <Text style={styles.buttonText}>{props.text}</Text>
    </TouchableOpacity>
  ),
  renderDismissButton: ({ onPress }) => (
    <TouchableOpacity onPress={onPress}>
      <Text>×</Text>
    </TouchableOpacity>
  ),
});

Slots

Slots allow you to inject custom content at specific positions within the alert:

alert.show({
  title: 'Alert with Slots',
  message: 'This alert uses slots for custom content',
  // Content before the title
  beforeTitleSlot: () => (
    <View style={styles.badge}>
      <Text style={styles.badgeText}>New</Text>
    </View>
  ),
  // Content before the message
  beforeMessageSlot: () => <View style={styles.divider} />,
  // Content before the buttons
  beforeButtonsSlot: () => (
    <View style={styles.terms}>
      <Text>By continuing you agree to our terms</Text>
    </View>
  ),
  // Content after the buttons
  afterButtonsSlot: () => (
    <View style={styles.footer}>
      <Text style={styles.footerText}>Need help? Contact support</Text>
    </View>
  ),
});

Async Operations

const result = await alert.show<string | null>({
  title: 'Async Operation',
  buttons: [
    {
      text: 'Confirm',
      onAwaitablePress: async (resolve) => {
        // Perform async operation
        resolve('Operation completed');
      },
    },
    {
      text: 'Cancel',
      onAwaitablePress: async (resolve) => {
        resolve(null);
      },
    },
  ],
});

Queue Management

// These alerts will be shown in sequence
alert.show({ message: 'First alert' });
alert.show({ message: 'Second alert' });
alert.show({ message: 'Third alert' });

Custom Button Props

You can extend the AlertButtonCustomProps interface to add custom properties to your buttons using TypeScript declaration merging:

// In your project's type declaration file (e.g., types.d.ts)
import 'react-native-alert-queue';

declare module 'react-native-alert-queue' {
  interface AlertButtonCustomProps {
    // Add your custom props here
    variant?: 'primary' | 'secondary' | 'danger';
    size?: 'small' | 'medium' | 'large';
    isLoading?: boolean;
    // ... any other custom props
  }
}

// Usage in your components
alert.show({
  title: 'Custom Button Props',
  message: 'This alert uses custom button props',
  buttons: [
    {
      text: 'Primary Button',
      customProps: {
        variant: 'primary',
        size: 'large',
        isLoading: true,
      },
    },
    {
      text: 'Secondary Button',
      customProps: {
        variant: 'secondary',
        size: 'medium',
      },
    },
  ],
  // you can define it globally in the config or override it here
  renderButton: (props) => (
    <TouchableOpacity
      style={[
        styles.button,
        styles[props.customProps.variant],
        styles[props.customProps.size],
      ]}
      onPress={props.onPress}
      disabled={props.disabled || props.customProps.isLoading}
    >
      {props.customProps.isLoading ? (
        <ActivityIndicator color="white" />
      ) : (
        <Text style={styles.buttonText}>{props.text}</Text>
      )}
    </TouchableOpacity>
  ),
});

Configuration

You can customize the default appearance and behavior of alerts using the config prop:

<AlertContainer
  config={{
    testID: 'alert_test_id',
    backdropBackgroundColor: 'rgba(255, 255, 255, 0.5)',
    alertStyle: {
      borderRadius: 20,
      padding: 20,
      backgroundColor: theme.colors.alert.background,
    },
    success: {
      icon: SuccessIcon,
      iconColor: 'green',
      title: 'Success',
    },
    error: {
      icon: ErrorIcon,
      iconColor: 'red',
      title: 'Error',
    },
    buttons: {
      gap: 10,
      default: {
        text: 'OK',
        testID: 'default-button',
      },
    },
  }}
/>
