Tiny but useful utilities.

Install

npm i @monteway/utils

Usage

trimMultiline

• Trims useless spaces from the beginning of each line.
• Removes empty new lines at the beginning and end of the input.
• Keeps the identation pattern.

Example

import { trimMultiline } from '@monteway/utils/format';

const code = `
  function foo() {
    return bar;
  }
`;

const output = trimMultiline(code);

• If we do console.log(code), the result will be:

    function foo() {
      return bar;
    }

• If we do console.log(output), the result will be different by trimming the trailing, useless spaces:

  function foo() {
    return bar;
  }

  This shows, that trimMultiline acts a little bit like Prettier.

Options

As a second, optional arguments we might pass an object:

{
  // Make sure the miniam identation is this number of spaces.
  indentBy?: number;

  // Keep a single new line at the beginning of the output (since by default it's removed).
  startWithNewLine?: boolean;
}
