Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Liturgical Calendar API

Liturgical Calendar is a simple tool for getting the dates of the Liturgical Calendar. It returns the dates of the Liturgical Calendar for a given year.

Build Status Code Climate Prod Ready npm version

This is a Javascript Wrapper for the Liturgical Calendar API


Installation

Using npm:

npm install @apiverve/liturgicalcalendar

Using yarn:

yarn add @apiverve/liturgicalcalendar

Configuration

Before using the Liturgical Calendar API client, you have to setup your account and obtain your API Key. You can get it by signing up at https://apiverve.com


Quick Start

Get started with the Quick Start Guide

The Liturgical Calendar API documentation is found here: https://docs.apiverve.com/ref/liturgicalcalendar. You can find parameters, example responses, and status codes documented here.

Setup

const liturgicalcalendarAPI = require('@apiverve/liturgicalcalendar');
const api = new liturgicalcalendarAPI({
    api_key: '[YOUR_API_KEY]'
});

Usage


Perform Request

Using the API is simple. All you have to do is make a request. The API will return a response with the data you requested.

var query = {
  month: 2,
  year: 2025
};

api.execute(query, function (error, data) {
    if (error) {
        return console.error(error);
    } else {
        console.log(data);
    }
});

Using Promises

You can also use promises to make requests. The API returns a promise that you can use to handle the response.

var query = {
  month: 2,
  year: 2025
};

api.execute(query)
    .then(data => {
        console.log(data);
    })
    .catch(error => {
        console.error(error);
    });

Using Async/Await

You can also use async/await to make requests. The API returns a promise that you can use to handle the response.

async function makeRequest() {
    var query = {
  month: 2,
  year: 2025
};

    try {
        const data = await api.execute(query);
        console.log(data);
    } catch (error) {
        console.error(error);
    }
}
