Remove indentation from multi-line strings

This feature allows you to write multi-line strings in your code with indentation for readability, and then process them with dedent to remove the extra leading whitespace.

const dedent = require('dedent');

const text = dedent`
    Line one
    Line two
    Line three
`;
console.log(text); // 'Line one\nLine two\nLine three'

An ES6 string tag that strips indentation from multi-line strings.

Usage

import dedent from "dedent";

function usageExample() {
  const first = dedent`A string that gets so long you need to break it over
                       multiple lines. Luckily dedent is here to keep it
                       readable without lots of spaces ending up in the string
                       itself.`;

  const second = dedent`
    Leading and trailing lines will be trimmed, so you can write something like
    this and have it work as you expect:

      * how convenient it is
      * that I can use an indented list
         - and still have it do the right thing

    That's all.
  `;

  const third = dedent(`
    Wait! I lied. Dedent can also be used as a function.
  `);

  return first + "\n\n" + second + "\n\n" + third;
}

> console.log(usageExample());
