React Native Fancy Alerts

Adaptation of nativescript-fancyalert for react native. Compatible with expo 🤓

Quick Start

$ npm i react-native-expo-fancy-alerts

Or

$ yarn add react-native-expo-fancy-alerts

import React from 'react';
import { Text, TouchableOpacity, View } from 'react-native';
import { FancyAlert } from 'react-native-expo-fancy-alerts';

const App = () => {
  const [visible, setVisible] = React.useState(false);
  const toggleAlert = React.useCallback(() => {
    setVisible(!visible);
  }, [visible]);

  return (
    <View>
      <TouchableOpacity onPress={toggleAlert}>
        <Text>Tap me</Text>
      </TouchableOpacity>

      <FancyAlert
        visible={visible}
        icon={<View style={{
          flex: 1,
          display: 'flex',
          justifyContent: 'center',

Examples

The following example illustrates how you can create a loading indicator for your entire app. If you're using redux you may have a part of your store which says whether you're loading something, you can get that flag and show one of the loading indicators offered by this lib.

import React from 'react';
import { useSelector } from 'react-redux';
import { LoadingIndicator } from 'react-native-expo-fancy-alerts';
import { selectIsLoading } from 'selectors';

const AppLoadingIndicator = () => {
  const isLoading = useSelector(selectIsLoading);
  return <LoadingIndicator visible={isLoading} />;
}

export default AppLoadingIndicator;

This next one is an error message that is also managed globally through redux.

import React from 'react';
import { Platform, Text, View, StyleSheet } from 'react-native';
import { useDispatch, useSelector } from 'react-redux';
import { FancyAlert } from 'react-native-expo-fancy-alerts';
import { Ionicons } from '@expo/vector-icons';
import { ErrorCreators } from 'creators';
import { selectError } from 'selectors';

const AppErrorModal = () => {
  const dispatch = useDispatch();
  const { hasError, error } = useSelector(selectError);

  const onRequestClose = React.useCallback(
    () => {
      dispatch(ErrorCreators.hideError());
    },
    [dispatch],
  );

  return <FancyAlert
    style={styles.alert}
    icon={
      <View style={[ styles.icon, { borderRadius: 32 } ]}>
        <Ionicons
          name={Platform.select({ ios: 'ios-close', android: 'md-close' })}
          size={36}
          color="#FFFFFF"
        />
      </View>
    }
    onRequestClose={onRequestClose}
    visible={hasError}
  >
    <View style={styles.content}>
      <Text style={styles.contentText}>{error ? error.message : ''}</Text>

      <TouchableOpacity style={styles.btn} onPress={onPress}>
        <Text style={styles.btnText}>OK</Text>
      </TouchableOpacity>
    </View>
  </FancyAlert>;
}

const styles = StyleSheet.create({
  alert: {
    backgroundColor: '#EEEEEE',
  },
  icon: {
    flex: 1,
    display: 'flex',
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#C3272B',
    width: '100%',
  },
  content: {
    display: 'flex',
    flexDirection: 'column',
    justifyContent: 'center',
    alignItems: 'center',
    marginTop: -16,
    marginBottom: 16,
  },
  contentText: {
    textAlign: 'center',
  },
  btn: {
    borderRadius: 32,
    display: 'flex',
    flexDirection: 'row',
    justifyContent: 'center',
    alignItems: 'center',
    paddingHorizontal: 8,
    paddingVertical: 8,
    alignSelf: 'stretch',
    backgroundColor: '#4CB748',
    marginTop: 16,
    minWidth: '50%',
    paddingHorizontal: 16,
  },
  btnText: {
    color: '#FFFFFF',
  },
});

export default AppErrorModal;
