Holiday API Node.js Library

Official Node.js library for Holiday API providing quick and easy access to holiday information from applications written in server-side JavaScript.

Migrating from 1.x

Please note, version 2.x of this library is a full rewrite of the 1.x series in TypeScript. The interfacing to the library has been simplified and existing applications upgrading to 2.x will need to be updated.

Version 1.x Syntax (Old)	Version 2.x Syntax (New)
const HolidayAPI = require('node-holidayapi');	import { HolidayAPI } from 'holidayapi';
const holidayApi = new HolidayAPI(key).v1;	const holidayApi = new HolidayAPI({ key });
holidayApi.holidays(params, (err, data) => {});	holidayApi.holidays(params).then((data) => {});

Version 1.x of the library can still be found here.
