Coded for a small personnal project, I put the component on npm. Don't hesitate to fork and do what you want with it!

How to install:

npm i react-loading-text

How to use

import React from "react";
import LoadingEffect from "react-loading-text";

const Text = () => {
  return (
    <LoadingEffect
      style={{
        default: [
          16,
          1,
          "white",
          2,
          0.5,
          "linear",
          () => alert("Loading finished!")
        ]
      }}
    >
      <p>Hello World!</p>
    </LoadingEffect>
  );
};

The LoadingEffect (name it like you want) component take a style object props. It can have 4 keys that correspond to the screen width:

• default > 1200px
• md > 992px
• sm > 768px
• xs <= 768px

Those keys are Array that have 6 elements, in order:

• lineheight: same that css, the height of one line
• numberline: the number of lines you want to make appears
• color
• delay: delay before the animation start, in second.
• duration: duration for one line to appear, in second.
• timing: like css, ease, linear, ease-in, ease-out, ease-in-out.
• callback : a function call when animation end.

Like that you can have responsive animations depending on how your text behave.
