Decode effect typing animation for React.

Install

Usage

import React, { useRef } from "react";
import DecodeAnimation from "react-decode-animation";

function App() {
	const ref = useRef(null);
	return (
		<div>
			<DecodeAnimation
				ref={ref}
				autoplay // will play when rendered
				text={"This is an animation Example"}
			/>
			<div>
				<button onClick={() => ref.current?.play()}>Play</button>

How To Use It

Before get started, please be noted that react-decode-animation is designed for short texts, and it's not ideal for long paragraphs.

Get Started

To get started, install the library.

npm install react-decode-animation

First, import react-decode-animation to your file.

import DecodeAnimation from "react-decode-animation";

Next, call DecodeAnimation and pass a string to text, we can also pass in autoplay if we want it to play once it renders.

<DecodeAnimation
	text={"Hello"} // required
	autoplay // This is optional, will play when rendered
/>

Animate Programatically

Sometime, we don't want the animation to play automatically, we want it to play when it's called. We can animate it by using a useRef() hook.

DecodeAnimationRef provides 3 functions, play() pause() reset().

import React, { useRef } from "react";
import DecodeAnimation from "react-decode-animation";

function App() {
	// If you're using TypeScript --> useRef<DecodeAnimationRef>(null) <-- remember to import
	const ref = useRef(null);
	return (
		<div>
			<DecodeAnimation ref={ref} text={"Animating by calling ref."} />
			<div>
				<button onClick={() => ref.current?.play()}>Play</button>
				<button onClick={() => ref.current?.pause()}>Pause</button>
				<button onClick={() => ref.current?.reset()}>Reset</button>
			</div>
		</div>
	);
}

:warning: There is another way to animate: Be very careful! Alternatively, we can animate it via states. Although not recommended(setting the same state will not work), it looks neat if you are just changing it once or twice.

import React, { useState } from "react";
import DecodeAnimation from "react-decode-animation";

function App() {
	// If you're using TypeScript --> useState<DecodeState>("Paused") <-- remember to import
	const [decodeState, setDecodeState] = useState("Paused");
	return (
		<div>
			<DecodeAnimation
				state={decodeState}
				text={"Animating by setting state."}
			/>
			<div>
				<button onClick={() => setDecodeState("Playing")}>Play</button>
				<button onClick={() => setDecodeState("Paused")}>Pause</button>
				<button onClick={() => setDecodeState("Reset")}>Reset</button>
			</div>
		</div>
	);
}

Choosing Characters (AllowedCharatersList)

By default, DecodeAnimation provides some basic character sets to work with. If you want to have a custom set of characters go see customCharacters.

You can choose what goes to your DecodeAnimation by specifying it on allowedCharacters.

// If you are only using one set
<DecodeAnimation
  text={"This text has numbers."}
  allowedCharacters="numbers"
/>

// If you are using multiple sets
<DecodeAnimation
  text={"This text has numbers and symbols."}
  allowedCharacters={["numbers", "symbols"]}
/>

Displaying Any Characters

<DecodeAnimation
	text={"This Text is encoded with greek alphabets."}
	customCharacters="ΑΒΓΔΕΖΗΘΙΛΜΝΞΟΠΡΣΤΥΦΧΨΩαβγδεζηθικλμνξοπρστυφχψω" // looks AWESOME
/>
// output: θαυνπΨοΙΧσγιολΣΨσιξηβθλΡζΓυΞΧγθηεΓαμΥυΙΜΔζ

You can input a custom set of characters if the provided allowedCharacters is not what you need. In this example, we can use some greek alphabets to generate the code. We don't have to worry about duplicated characters DecodeAnimation will remove it automatically.

Animation Duration

There are 2 intervals that we can set. Play around to get the desired results.

interval

The duration of each character reveal (in Milliseconds). if inverval={1000}, DecodeAnimation will reveal a character every 1 second.

<DecodeAnimation
	text={"This Text is encoded with greek alphabets."}
	interval={100} // reveals a character every 100ms
/>

characterOptions

It is for the duration of each character looping speed. By default, characterOptions={{ intervalDeviation: 10, interval: 100 }}. characterOptions.interval is the base interval, and characterOptions.intervalDeviation is the milliseconds that the interval can deviate from.

// Example
<DecodeAnimation
	text={"This Text is encoded with greek alphabets."}
	characterOptions={{ intervalDeviation: 20, interval: 70 }}
/>
// the interval of each character is ranged from 50 - 90
// the lower the interval, the smoother loop it gets
