React Middle Ellipsis

Check out the demo.

Adding ellipses to the end of long text is cool. But not always! Sometimes the end of the text contains vital information, particularly for URLs or filenames.

• https://finance.bigdata.example.com/market/analys... (how ellipsing generally works)
• https://finance.bigdata.example.com/mark.../NVDA.pdf (how you might want it to work)

This React component is designed with that use case in mind.

Install

yarn add react-middle-ellipsis

Usage

Once imported, you can then wrap any node with <MiddleEllipsis>. This will compute the width of the surrounding parent node. Then, it will look for the child node (so make sure to add a span at minimum internally): it will use this element to compute the width of the child, and then shorten the text element whose class is ellipseMe (optional) to fit within the parent.

The component re-computes things if the browser window is resized, too!

import React from "react";
import MiddleEllipsis from "react-middle-ellipsis";

const Component = props => {
  return (
  <>
    <div style={{ width: "350px", whiteSpace: "nowrap" }}>
      <MiddleEllipsis>
        <span>
          I am some long text that should be ellipsed in the middle because
          the end contains important stuff.
        </span>
      </MiddleEllipsis>
    </div>
    <div style={{ width: "350px", whiteSpace: "nowrap" }}>
      <MiddleEllipsis>
        <span>
          Don't ellipse me.{" "}
          <span className="ellipseMe">
            I am some long text that should be ellipsed in the middle because
            the end contains important stuff.
          </span>
        </span>
      </MiddleEllipsis>
    </div>
  <>
  );
};

export default Component;
