This repo hasn't been maintained for about two years and I don't have any plans to continue working on it.
A React Native component for creating typing effects. Inspired by react-typewriter.
$ yarn add react-native-typewriter
OR
$ npm install --save react-native-typewriter
Pass text and a typing direction into the component to control its animation.
import React, { Component } from 'react'
import TypeWriter from 'react-native-typewriter'
class TypingText extends Component {
render() {
return <TypeWriter typing={1}>Hello World!</TypeWriter>
}
}Any props accepted by React Native's Text component are accepted by TypeWriter. These additional props are also accepted:
type: Number default: 0
A value of 1 types text left to right until completion. A value of -1 erases text from right to left. A value of 0 stops the animation.
type: Boolean default: false
This flag will ensure the enclosing container's size and shape is fixed. Prevents the text from shifting around as it grows into its container.
type: Number default: 100
The maximum delay between each typed token in milliseconds.
type: Number default: 20
The minimum delay between each typed token in milliseconds.
type: Array[Object] default: none
Adds additional delay to specific characters before the next character is typed.
let delayMap = [
// increase delay by 100ms at index 4
{ at: 4, delay: 100 },
// increase delay by 400ms following every '.' character
{ at: '.', delay: 400 },
// decrease delay by 200ms following every '!' character
{ at: /!/, delay: -200 }
]type: Number default: 200
The time in milliseconds before the first token is typed.
type: Function default: none
A callback called when each token is typed or erased during the animation. The
function is called with two arguments:
(String token, Number previousVisibleCharacters).
type: Function default: none
Called once the typing animation has completed. This callback is not called
if props.typing is changed to 0 before the animation completes.
