string-collapse-leading-whitespace

Collapse the leading and trailing whitespace of a string

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, 5.1.0.

npm i string-collapse-leading-whitespace

Quick Take

import { strict as assert } from "assert";

import { collWhitespace } from "string-collapse-leading-whitespace";

// if leading/trailing whitespace doesn't contain \n, collapse to a single space
assert.equal(collWhitespace("  aaa   "), " aaa ");

// otherwise, collapse to a single \n (default setting)
assert.equal(collWhitespace("     \n\n   aaa  \n\n\n    "), "\naaa\n");

// does nothing to trimmed strings:
assert.equal(collWhitespace("aaa"), "aaa");

// if there are multiple lines string is still processed in trim-fashion -
// only beginning and ending whitespace is changed:
assert.equal(
  collWhitespace("  abc  \n  def  \n  ghi  "),
  " abc  \n  def  \n  ghi "
);
