Handling holidays with 💪 typings using TypeScript

A Moment.js plugin for handling holidays at scale.

Another holiday library?

With date-holidays and kodie's moment-holiday, there are two alternatives to @nesto-software/moment-holiday. We want to improve the existing approaches by providing a high-performance solution for enterprise Node.js backends.

As we found out, there are a lot of challenges in providing a library which covers most business needs in the B2B sector. We face customers who want to bring in their own holidays. In order to do so, we provide database integration and a caching strategy to reduce the impact of database queries whenever possible. Click here if you are curious how we do it.

For a list of currently supported countries, click here. If your country is missing, we want to encourage you to add your locale bundle by submitting a PR.

Our main focus is on Node.js as we think that it is most effective if holidays are managed centrally and exposed through a REST API. However, there is browser support if you want to use this library in the frontend.

Features

• 🚀 Built for Node.js and Browser
• ⚡️️ Simple, Powerful, & Intuitive API
• 💪 Typings using TypeScript

Roadmap

1. Increase test coverage.
2. Provide better documentation and usage examples.
3. Encourage developers to help increasing the number of supported countries.

Usage

import moment from "moment";  // always import moment before moment-holiday (peer-dependency with side effects)
import createMomentHolidayConfiguration from "@nesto-software/moment-holiday";

// create a holiday configuration for Germany / Bavaria
const holidays = createMomentHolidayConfiguration("DE", "BY");
const holidays2018 = holidays.in(2018);

// display the holiday names and their corresponding date for 2018
console.log(holidays2018.map(holiday => holiday.name + " - " + holiday.moment.format("DD.MM.YYYY")));
