react-native-text-ticker v1.14.0

react-native-text-ticker

Screenshot

Description

Inspired from the great react-native-marquee, this module acts similarly but with a few extra features and props:

• Don't scroll the text if it fits in the container
• Infinitely scroll text in a ticker fashion
• Bounce text from side to side if it's only slightly wider than its container
• Grab the text and scroll it manually

To see it in action check out the example!

This package aims to only support the latest version of React-Native.

Installation

npm install --save react-native-text-ticker
or
yarn add react-native-text-ticker

Usage

This module can be used as a drop in replacement for the react-native Text component (extra props optional).

import React, { PureComponent } from 'react'
import { StyleSheet, View } from 'react-native'
import TextTicker from 'react-native-text-ticker'

export default class Example extends PureComponent {
  render(){
    return(
      <View style={styles.container}>
        <TextTicker
          style={{ fontSize: 24 }}
          duration={3000}
          loop
          bounce
          repeatSpacer={50}
          marqueeDelay={1000}
        >
          Super long piece of text is long. The quick brown fox jumps over the lazy dog.
        </TextTicker>
      </View>
    )
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
});

react-native-text-ticker supports a single child text string, any other use may give unexpected behaviour.

Prop	Type	Optional	Default	Description
style	StyleObj	true	-	Text Style
duration	number	true	150ms * length of string	Number of milliseconds until animation finishes
bounceSpeed	number	true	50	Describes how fast the bounce animation moves. Effective when duration is not set.

animationType	string	true	'auto'	one of the values from 'auto', 'scroll', 'bounce'
loop	boolean	true	true	Infinitely scroll the text, effective when animationType is 'auto'
bounce	boolean	true	true	If text is only slightly longer than its container then bounce back/forwards instead of full scroll, effective when animationType is 'auto'
scroll	boolean	true	true	Gives the ability to grab the text and scroll for the user to read themselves. Will start scrolling again after marqueeDelay or 3000ms
marqueeOnMount	boolean	true	true	Will start scroll as soon as component has mounted. Disable if using methods instead.
marqueeDelay	number	true	0	Number of milliseconds to wait before starting marquee
onMarqueeComplete	function	true	-	This function will run after the text has completely passed across the screen. Will run repeatedly if loop is enabled.
onScrollStart	function	true	-	This function will run if the text is long enough to trigger the scroll.
isInteraction	boolean	true	true	Whether or not animations create an interaction handle on the InteractionManager. Disable if you are having issues with VirtualizedLists not rendering properly.
useNativeDriver	boolean	true	true	Use native animation driver, should remain true for large majority of use-cases
repeatSpacer	number	true	50	The space between the end of your text string ticker and the beginning of it starting again.
bouncePadding	{ left: number, right: number }	true	-	The padding on start/end positions of bounce.
bounceDelay	number	true	0	How long the animation should wait after each bounce before starting again.
easing	function	true	Easing.ease	How the text scrolling animates. Additional options available from the Easing module
shouldAnimateTreshold	number	true	0	If you have a view drawn over the text at the right (a fade-out gradient for instance) this should be set to the width of the overlaying view:
disabled	boolean	true	false	Disables text animation
