MOMENT 2.30.x · MAINTAINED FORK

@stackline/moment

A maintained Moment.js fork for parsing, validating, manipulating, formatting, and localizing dates with the classic API teams still depend on in production.

Legacy-compatible API Keep the upstream Moment.js surface for parsing, locale loading, durations, and relative time output.
Versioned docs history Every published package line gets its own docs source and compiled demo so behavior stays aligned with npm.
Interactive explorer Switch between parsing, formatting, UTC, locale, duration, and comparison scenarios without leaving the page.
Browser-ready assets Each docs line uses the actual minified assets from the published tarball for that package version.

Setup in 3 steps

1
Install 
npm install @stackline/moment
2
Import the package 
import moment from '@stackline/moment';
import '@stackline/moment/locale/fr';
3
Run the date workflow 
moment.locale('fr');

const value = moment('2026-04-05 09:30', 'YYYY-MM-DD HH:mm', true);
value.clone().utc().format('YYYY-MM-DDTHH:mm:ss[Z]');

Example explorer

Browse the maintained Moment.js API by workflow instead of reading a flat README: parsing, strict validation, locale rendering, UTC offsets, durations, and range comparisons all stay visible in one place.
