react-textfitfix

This is a clone of the original repo, which is not maintained anymore and has compatibility problems with the latest version of React. I also included the type declarations in case you use TS.

• fit headlines and paragraphs into any element
• fast: uses binary search for efficiently find the correct fit
• 100% react-goodness
• works with any style configuration (line-height, padding, ...)
• check out the demo

Usage

Headlines

import { Textfit } from "react-textfitfix";

class App extends Component {
  render() {
    return <Textfit mode="single">Fat headline!</Textfit>;
  }
}

Respect the element's height when using single lines

import { Textfit } from "react-textfitfix";

class App extends Component {
  render() {
    return (
      <Textfit mode="single" forceSingleModeWidth={false}>
        Fat headline!
      </Textfit>
    );
  }
}

    return (
      <Textfit mode="multi">

    );
  }
}

Modes

single

Algorithm steps:

1. binary search to fit the element's width
2. if forceSingleModeWidth=false and text overflows height
    2a. binary search to also fit the elements height

multi

Algorithm steps:

1. binary search to fit the element's height
2. if text overflows width
    2a. binary search to also fit the elements width
