dayjs-parser

The most comprehensive and accurate date parser for Node and browsers. It uses Intl to provide parsing support for all installed locales. This plugin connects the capabilities of any-date-parser to dayjs.

It allows passing every imaginable date format to the dayjs() function. Most locales are supported automatically.

Motivation

1. The APIs I consume have a lot of different date formats
2. I want to create REST APIs that accept all major formats
3. I want to handle user-input dates
4. I want to support dates in other languages according to JavaScript's new Intl global object

Installation

npm install dayjs dayjs-parser

Usage

Register as a regular dayjs plugin

import dayjs from 'dayjs';
import dayjsParser from 'dayjs-parser';

dayjs.extend(dayjsParser);

const date1 = dayjs('Wed Jan 19 2022 17:52:46');
const date2 = dayjs('in 2 weeks');
const date3 = dayjs('2016-03-05T23:59:59.000Z');

Breaking changes v0.x => v1.x

Dropped support for importing from dayjs-parser/dayjs. Now you must register dayjsParser as a plugin. Both cjs and esm now supported.

Locale Support

Locales are supported by first setting the global locale:

import dayjs from 'dayjs';
import dayjsParser from 'dayjs-parser';

dayjs.extend(dayjsParser);
dayjs.locale('fr');

const date = dayjs('15 septembre 2015');

Note that your system must have that locale installed.

See the Dayjs docs on locales

Sister Packages

Unit Testing

dayjs-parser has 100% code coverage.

• To run tests, run npm test
• To check coverage, run npm run coverage

Unit tests require a global install of full-icu and dayjs. The test runner will attempt to install these if absent.
