Package Exports

react-native-toast-message

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-native-toast-message) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

ToastSuccess

Usage

Render the Toast component in your app entry file (along with everything that might be rendered there) and set a ref to it.

// App.jsx
import Toast from 'react-native-toast-message';

function App(props) {
  return (
    <>
      {/* ... */}
      <Toast ref={(ref) => Toast.setRef(ref)} />
    </>
  );
}

export default App;

Then use it anywhere in your app (even outside React components), by calling any Toast method directly:

import Toast from 'react-native-toast-message';

function SomeComponent() {
  React.useEffect(() => {
    Toast.show({
      type: 'success',
      text1: 'Hello',
      text2: 'This is some something 👋'
    });
  }, []);

  return <View />;
}

API

`show(options = {})`

When calling the show method, you can use the following options to suit your needs. Everything is optional, unless specified otherwise.

The usage of | below, means that only one of the values show should be used. If only one value is shown, that's the default.

Toast.show({
  type: 'success | error | info',
  position: 'top | bottom',
  text1: 'Hello',
  text2: 'This is some something 👋',
  visibilityTime: 4000,
  autoHide: true,
  topOffset: 30,
  bottomOffset: 40,
  onShow: () => {},
  onHide: () => {}, // called when Toast hides (if `autoHide` was set to `true`)
  onPress: () => {},
  props: {} // any custom props passed to the Toast component
});

`hide()`

Toast.hide();

props

Props that can be set on the Toast instance. They act as defaults for all Toasts that are shown.

const props = {
  type: 'success | error | info',
  position: 'top' | 'bottom',
  visibilityTime: Number,
  autoHide: Boolean,
  topOffset: Number,
  bottomOffset: Number,
  keyboardOffset: Number,
  config: Object,
  style: ViewStyle,
  height: Number
};

Default Animated.View styles can be found in styles.js. They can be extended using the style prop.

Customize layout

If you want to add custom types - or overwrite the existing ones - you can add a config prop when rendering the Toast in your app root.

You can either use any of the default BaseToast, SuccessToast, ErrorToast or InfoToast components and adjust their layout, or create Toast layouts from scratch.

// App.jsx
import Toast, { BaseToast, ErrorToast } from 'react-native-toast-message';

const toastConfig = {
  /* 
    overwrite 'success' type, 
    modifying the existing `BaseToast` component
  */
  success: ({ text1, props, ...rest }) => (
    <BaseToast
      {...rest}
      style={{ borderLeftColor: 'pink' }}
      contentContainerStyle={{ paddingHorizontal: 15 }}
      text1Style={{
        fontSize: 15,
        fontWeight: '400'
      }}
      text1={text1}
      text2={props.uuid}
    />
  ),

  /*
    Reuse the default ErrorToast toast component
  */
  error: (props) => (
    <ErrorToast
      {...props}
      text1Style={{
        fontSize: 17
      }}
      text2Style={{
        fontSize: 15
      }}
    />
  ),
  /* 
    or create a completely new type - `my_custom_type`,
    building the layout from scratch
  */
  my_custom_type: ({ text1, props, ...rest }) => (
    <View style={{ height: 60, width: '100%', backgroundColor: 'tomato' }}>
      <Text>{text1}</Text>
    </View>
  )
};

function App(props) {
  // pass `toastConfig` to the Toast instance
  return (
    <>
      <Toast config={toastConfig} ref={(ref) => Toast.setRef(ref)} />
    </>
  );
}

export default App;

Then just use the library as before

Toast.show({
  type: 'my_custom_type',
  props: { uuid: 'bba1a7d0-6ab2-4a0a-a76e-ebbe05ae6d70' }
});

Available props on BaseToast:

const baseToastProps = {
  leadingIcon: ImageSource,
  trailingIcon: ImageSource,
  text1: String,
  text2: String,
  onPress: Function,
  onLeadingIconPress: Function,
  onTrailingIconPress: Function,
  style: ViewStyle,
  leadingIconContainerStyle: ViewStyle,
  trailingIconContainerStyle: ViewStyle,
  leadingIconStyle: ViewStyle,
  trailingIconStyle: ViewStyle,
  contentContainerStyle: ViewStyle,
  text1Style: ViewStyle,
  text2Style: ViewStyle,
  activeOpacity: Number
};

FAQ

To have the toast visible on top of the navigation View hierarchy, render it as the last child inside NavigationContainer.

import Toast from 'react-native-toast-message'
import { NavigationContainer } from '@react-navigation/native';

export default function App() {
  return (
    <NavigationContainer>
      {...}
      <Toast ref={(ref) => Toast.setRef(ref)} />
    </NavigationContainer>
  );
}

How to mock the library for testing with jest?

jest.mock('react-native-toast-message', () => ({
  show: jest.fn(),
  hide: jest.fn()
}));

When a Modal is visible, the Toast gets rendered behind it. This is due to the way Modal is implemented. As a workaround, you can have 2 separate Toast instances: one inside the Modal (let's call it a "modal toast") and a normal one outside.

For the one outside, set the ref on the Toast object (like usual)

<Toast ref={ref => Toast.setRef(ref) />

And for the "modal toast", use another ref

function ScreenWithModal() {
  const modalToastRef = React.useRef();

  return (
    <Modal>
      <Toast ref={modalToastRef} />
    </Modal>
  );
}

Then, when you want to show the "modal toast", call it using modalToastRef.current.show().
