Install

The latest version is ESM only: Node 12+ is needed to use it and it must be imported instead of required. If your project is not on ESM yet and you want to use require, use an older version of this program, 6.1.0.

npm i string-extract-class-names

Quick Take

import { strict as assert } from "assert";

import { extract } from "string-extract-class-names";

// extracts classes and/or id's
const str = "div#brambles.nushes#croodles";
const { res, ranges } = extract(str);
assert.deepEqual(res, ["#brambles", ".nushes", "#croodles"]);
assert.deepEqual(ranges, [
  [3, 12],
  [12, 19],
  [19, 28],
]);

// `res` can be produced by slicing `ranges`:
assert.deepEqual(
  res,
  ranges.map(([from, to]) => str.slice(from, to))
);
