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 2.x

In an attempt to stay current with both our development and production dependencies, the decision was made to drop testing and advertised compatibility with Node.js versions that are outside of their maintenance window.

For the 3.x release, testing for Node.js 13.x was added while testing for Node.js 7.x, 9.x and 11.x was dropped. Even though these older versions may still continue to work, they become harder to test against as our dependencies improve and drop support for those versions.

In the future, when compatibility changes, we will increment the major version number of the release as well as document the additions and deprecations in the release notes.

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.
