React ASCII Text

This library provides a React hook to render or animate ASCII text art using Figlet fonts. Works with React 17 +, including Next.js App Router (the "use client" directive is already included in the package).

DEMO Try the code out on StackBlitz

Installation

npm install react-ascii-text
# or
pnpm add react-ascii-text
# or
yarn add react-ascii-text

Usage

Figlet fonts are included in the package and can be imported. Full list of fonts along with UI to try them out can be found here.

Note that the font names are converted to camelCasing, omitting spaces and hyphens to allow use as ES modules. This allows bundlers to include only the fonts you actually import.

Font name	Import
1Row	import { oneRow } from 'react-ascii-text'
3-D	import { threeD } from 'react-ascii-text'
5 Line Oblique	import { fiveLineOblique } from 'react-ascii-text'
Big Money-sw	import { bigMoneySw } from 'react-ascii-text'
etc.

Render ASCII text

Passing a single string will render the text in a Figlet font.

import { useAsciiText, alligator } from 'react-ascii-text';

function MyComponent() {
  const asciiTextRef = useAsciiText({
    font: alligator,
    text: "Hello, World!",
  });

  return <pre ref={asciiTextRef}></pre>;
}

Animate ASCII text

Pass an array of strings to animate a transition between them.

import { useAsciiText, alligator } from 'react-ascii-text';

function MyComponent() {
  const asciiTextRef = useAsciiText({
    animationCharacters: "▒░█",
    animationCharacterSpacing: 1,
    animationDelay: 2000,
    animationDirection: "down",
    animationInterval: 100,
    animationLoop: true,
    animationSpeed: 30,
    font: alligator,
    text: ["REACT", "ASCII", "TEXT"],
  });

  return <pre ref={asciiTextRef}></pre>;
}

Parameters

• animationDirection (optional, default: "horizontal"): Direction of the animation. One of "down", "up", "left", "right", "horizontal", or "vertical".
• animationCharacters (optional, default: "/*+#"): Characters used to replace text during the animation transition.
• animationCharacterSpacing (optional, default: 1): Spacing between animation characters.
• animationDelay (optional, default: 500): Pause duration in ms at the midpoint of each animation.
• animationInterval (optional, default: 1000): Gap in ms between consecutive animations.
• animationIteration (optional, default: 1): Number of times the animation repeats before stopping (ignored when animationLoop is true).
• animationLoop (optional, default: true): Whether the animation loops indefinitely.
• animationSpeed (optional, default: 20): Frame throttle in ms — lower values are faster.
• fadeInOnly (optional, default: false): Only play the fade-in half of the animation.
• fadeOutOnly (optional, default: false): Only play the fade-out half of the animation.
• font (optional, default: Slant): Figlet font data to use for rendering.
• isAnimated (optional, default: true): Render static text when false.
• isPaused (optional, default: false): Reactive prop — set to true to pause the animation, false to resume.
• text (optional, default: ["React", "ASCII", "Text"]): Text to render. A single string renders statically; an array animates transitions between each string.
