Why this library?

@stackline/moment-core keeps the stable Moment.js API available under active package ownership for teams that still depend on its parsing, formatting, locale, duration, and relative-time behavior. The package stays intentionally close to the classic Moment.js API, while cleaning up metadata and preserving browser-ready bundles, locale files, and TypeScript declarations.

Moment remains a legacy API in maintenance mode. New applications should evaluate modern date/time libraries, while existing applications can use this package when behavioral compatibility is the primary requirement. The package version is 1.0.3; moment.version intentionally remains 2.30.1 for runtime compatibility.

Installation

npm install @stackline/moment-core

Direct Download

If your project loads JavaScript directly in the browser, download the prebuilt release from GitHub:

• GitHub downloads folder

The archive includes moment.min.js, moment-with-locales.min.js, and locales.min.js.

<script src="./moment.min.js"></script>
<script>
  const value = moment('2026-04-03 14:30', 'YYYY-MM-DD HH:mm', true);
  console.log(value.isValid(), value.format('LLLL'));
</script>

<script src="./moment-with-locales.min.js"></script>
<script>
  moment.locale('fr');
  console.log(moment().format('LLLL'));
</script>

Setup

import moment from '@stackline/moment-core';
import '@stackline/moment-core/locale/fr';

moment.locale('fr');

Basic Usage

import moment from '@stackline/moment-core';

const parsed = moment('2026-04-03 14:30', 'YYYY-MM-DD HH:mm', true);

const isoOutput = parsed.clone().utc().format('YYYY-MM-DDTHH:mm:ss[Z]');
const longOutput = parsed.format('LLLL');
const relativeOutput = parsed.fromNow();

console.log({ isoOutput, longOutput, relativeOutput });

Core APIs

| API | Description | | :--- | :--- | | moment(input) | Creates a local instance from strings, numbers, arrays, objects, and native Date values. | | moment(input, format, strict) | Parses using a declared token pattern and optional strict validation. | | moment.utc(input) | Creates a UTC-based moment instance. | | moment.parseZone(input) | Preserves the original offset encoded in the input string. | | moment.duration(value, unit) | Creates a duration for humanize, ISO serialization, and unit conversion. | | moment.locale(locale) | Sets the active locale for formatting and relative time output. | | moment.relativeTimeThreshold(unit, value) | Tunes relative time cutover thresholds. | | moment.relativeTimeRounding(fn) | Overrides rounding behavior for relative time strings. |

Browser Assets

The published package keeps the classic Moment.js distribution layout:

| File | Description | | :--- | :--- | | moment.js | Classic CommonJS/browser entry | | dist/moment.js | ESM-friendly build | | locale/ | Individual locale bundles | | min/moment.min.js | Browser-ready minified build | | min/locales.min.js | Browser-ready locale bundle | | min/moment-with-locales.min.js | Browser-ready build with locales included | | moment.d.ts | TypeScript declarations | | ts3.1-typings/ | Alternate declarations for TS 3.1+ consumers |

Run Locally

The maintained development dependencies use exact Stackline aliases. The karma override references the direct dependency ($karma) so the compatible Classic Karma API satisfies the installed plugins' peer graph. A fresh install, npm ls --all, audit and actual Chromium/Firefox tests validate this setup; --legacy-peer-deps is not used. Historical TypeScript packages remain independent compatibility compilers. Inherited Grunt/Karma transitive deprecations are recorded under the original-parent-only migration scope, without claiming an unrestricted dependency-closure policy pass.
