react-textfit - TypeScript

React-textfit is a React component that dynamically scales the font size of given text to fit within its container. It is written in TypeScript which provides strong typing, making it easier to refactor your code and maintain it in the long-term.

Installation

You can install react-textfit using npm:

npm install react-textfit

Usage

Once installed, you can use the Textfit component like this:

import React from "react";
import Textfit from "react-textfit";

const App = () => {
  return (
    <div style={{ width: "200px", height: "100px" }}>
      <Textfit mode="single" forceSingleModeWidth={false}>
        {"Hello World!"}
      </Textfit>
    </div>
  );
};

React textfit will automatically adjust the font size of the text to fit within the parent container. You can also set additional properties like mode to control how the font size adjusts.

Props

The Textfit component accepts several props that allow you to customize its behavior:

• mode: The mode tells Textfit how to adjust the font size. The default value is multi, which adjusts the font size to fit within the container's width and height. Single mode adjusts the font size to always fit within the container's width, but lets the height fall wherever it may. This is useful for longer strings, as they need to fit within their width to be readable, but may vary in height.
• min: Sets the minimum font size.
• max: Sets the maximum font size.
• forceSingleModeWidth: Setting this to true makes sure the text always fits within its container regardless of container width changes in single mode. This is useful for dynamically resized containers.
• style: Component style.

Conclusion

React-textfit is a useful library for scaling font sizes dynamically - making text preffered by users at its best appearance, and ensuring readability by containers. By using TypeScript, it provides strong typing and an easier way to maintain your codebase in future.
