Example

const appearAnimation = new SlideX(Dimensions.get('screen').width, 0);
const holdAnimation = new Zoom(1, .95, { duration: 200, useNativeDriver: true });

const toastMiddleware = ({ type, message }: Item) => {
  if (type !== ToastType.ERROR) {
    return message;
  }

  if (typeof message === 'string') {
    return message;
  }

  if (message.response && message.response.data && message.response.data.message) {
    return message.response.data.message;
  } else {
    return 'Some error was happened :(';
  }
};

      onHide={onHide}

Public interface

< Toaster />

Toaster component represents a container that displays messages.

Accepts the following props:

onHide - a callback that executes AFTER message gets hidden. Optional. Takes native event as the first argument and message item as the second argument.

onShow - a callback that executes BEFORE message gets shown. Optional. Takes native event as the first argument and message item as the second argument.

onPress - a callback that executes on container press. Optional. Takes native event as the first argument and message item as the second argument.

onHoldStart - a callback that executes when a user holds their touch on message. Optional. Takes native event as the first argument and message item as the second argument.

onHoldEnd - a callback that executes when a user releases their touch from message after holding it. Optional. Takes native event as the first argument and message item as the second argument.

duration - specifies common display time in msec for messages. Optional. Default - 2000.

delayBetween - specifies delay time in msec between showing messages. Optional. Default - 0.

hideOnPress - specifies that the message should be closed when a user touches it. Optional. Default - false.

containerViewProps - specifies props for the container's element. Optional.

animation - specifies animation that applies to hide/show the message. Optional. Default - SlideY. See more details below.

middleware - executes before the message will be added to a queue. Should return string. Optional. Takes message item as argument.

Toaster can take children only as function:

(item: { type: string; message: string }) => React.ReactNode;

In this case, the default Toast will be replaced with the returned component.

NOTE: To stop hide-timer, you can tap and hold your touch on the container as long as you want

Message item

Message item represents the following interface:

item: {
	message: string;
	type: "INFO" | "ERROR" | "SUCCESS" | "DEBUG";
	duration?: number;
}

Creating a message

Toaster is a singleton. So make sure that you have only one instance.

Toaster has several static methods for messages creation:

/*
	the first argument specifies the message. REQUIRED.
	the second argument specifies the duration. OPTIONAL. By default - value from props.
*/

Toaster.info("message", 500);
Toaster.error("message", 500);
Toaster.success("message", 500);
Toaster.debug("message", 500);

Animation

There are several built-in animations:

• Opacity
• SlideX
• SlideY
• Zoom

/*
	- the first argument specifies start-animation value. REQUIRED.
	- the second argument specifies end-animation value. REQUIRED.
	- the third argument specifies the animation config. This is the same config as in AnimationTimingConfig. OPTIONAL. (https://facebook.github.io/react-native/docs/animated)
*/
new Opacity(0, 1, {
		duration: 250,
		useNativeDriver: true
	});

Each animation extends BaseAnimation and implements ToasterAnimation. So if you want to create custom animation, make sure you correctly implement it:

class MyCustomAnimation extends BaseAnimation implements ToasterAnimation {
	/*
		1. Animated.timing SHOULD BE WRAPPED INTO PROMISE.
		2. styles SHOULD RETURN VALID OBJECT STYLES.
	*/
	
	// start animation forward
	forward() {
		return new Promise((resolve) => {
			Animated.timing(this.value, {
				toValue: this.from,
				...this.config
			}).start(resolve);
		});
	}

	// start animation backward
	backward() {
		return new Promise((resolve) => {
			Animated.timing(this.value, {
				toValue: this.from,
				...this.config
			}).start(resolve);
		});
	}
	
	// applies animation to the container
	styles = {
		transform: [{ scale: this.value }]
	}
}

// ...

const animation = new MyCustomAnimation(-2, 15);

<Toaster animation={animation} />

NOTE: Always create animation instances outside from the component body OR use memoisation
