# or
yarn add react-typist-component

Example

import Typist from 'react-typist-component';

const MyComponent = () => {
  return (
    <Typist typingDelay={100} cursor={<span className='cursor'>|</span>}>
      This is a typo
      <br />
      <Typist.Backspace count={5} />
      <Typist.Delay ms={1500} />
      react component
      <Typist.Paste>
        <div>
          use
          <div>deeper div</div>
        </div>
      </Typist.Paste>
    </Typist>
  );
};

API reference

Typist

export type Delay = number | (() => number);
export type Splitter = (str: string) => string[];
export type TypistProps = {
  children: React.ReactNode;
  typingDelay?: Delay;
  backspaceDelay?: Delay;
  loop?: boolean;
  pause?: boolean;
  startDelay?: number;
  finishDelay?: number;
  onTypingDone?: () => void;
  splitter?: Splitter;
  cursor?: string | React.ReactElement;
  disabled?: boolean;
  restartKey?: any;
  hideCursorWhenDone?: boolean;
};

children

The contents that will be rendered with typewriter effect. It accepts nested elements, so you can easily style your contents.

Note that Typist treats the element whose children is null or undefined as a single token. For example:

const Foo = () => {
  return <div>Foo</div>;
};

// The text "Foo" will be displayed after "123" immediately instead of displayed seperately
const App = () => {
  return (
    <Typist>
      123
      <Foo />
    </Typist>
  );
};

typingDelay

Default: 75

The delay after typing a token. If you pass in a function, Typist will call the function after typing a token and use the return value as the delay.

backspaceDelay

Default: typingDelay

The delay after backspacing a token. If you pass in a function, Typist will call the function after backspacing a token and use the return value as the delay.

loop

Default: false

Typist will automatically restart the typing animation if this value is true.

pause

Default: false

Set to true if you want to pause the typing animation.

startDelay

Default: 0

Typist will wait for this delay before starting the typing animation.

finishDelay

Default: 0

Typist will wait for this delay after finishing the typing animation.

onTypingDone

This function will be called when the typing animation finishes. It will be called before waiting for the timeout with finishDelay.

splitter

Default: (str: string) => str.split('')

Typist will use this function to get tokens from strings. It may be useful when you want to split your string in different way. For example, you can use grapheme-splitter to split string if your string contains emoji.

import GraphemeSplitter from 'grapheme-splitter';

const splitter = (str: string) => {
  return new GraphemeSplitter().splitGraphemes(str);
};

const App = () => {
  return (
    <Typist splitter={splitter}>
      😎🗑🥵⚠😀👍✌👨‍👨‍👧‍👦📏💡🚀🎂😓🎈💕😘
      <Typist.Backspace count={16} />
    </Typist>
  );
};

cursor

Will be inserted after the last typed token.

disabled

Default: false

If this value is true, the result will be displayed immediately without typing animation. It can be useful when you want to display the final result if a user has visited the typing animation.

restartKey

Typist will restart the typing animation whenever restartKey changes.

hideCursorWhenDone

Hide the cursor when the typing animation is done.

Typist.Backspace

type Props = {
  count: number;
};

count

The number of tokens that will be backspaced.

Typist.Delay

type Props = {
  ms: number;
};

ms

The duration of the delay in milliseconds.

Typist.Paste

type Props = {
  children: React.ReactNode;
};

children

Children inside this component will be pasted without typewriter effect. Do not wrap another Paste inside this component, otherwise Typist will produce weird behavior.
