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.


Hi, πŸ‘‹, I’m Ryan HefnerΒ  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 πŸ™

| | Status | | - | - | | Build | Node CI Dependencies GitHub release (latest by date) Snyk Vulnerabilities for GitHub Repo | | Health | License Coverage Pull Request Labeler | | Community | NPM type definitions NPM All contributors |

JavaScript library to generate an event link for Google Calendar, Yahoo! Calendar, Microsoft Outlook, etc.



// Usage with Node.js
const { google, outlook, office365, yahoo, ics } = require("calendar-link");

// Usage with TypeScript or ES6
import { google, outlook, office365, yahoo, ics } from "calendar-link";

// Set event as an object
const event = {
  title: "My birthday party",
  description: "Be there!",
  start: "2019-12-29 18:00:00 +0100",
  duration: [3, "hour"],

// Then fetch the link
google(event); //
outlook(event); //
office365(event); //
yahoo(event); //
ics(event); // standard ICS file based on


| Property | Description | Allowed values | | ------------------ | --------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------- | | title (required) | Event title | String | | start (required) | Start time | JS Date / ISO 8601 string / Unix Timestamp | | end | End time | JS Date / ISO 8601 string / Unix Timestamp | | duration | Event duration | Array with value (Number) and unit (String) | | allDay | All day event | Boolean | | rRule | Recurring event | iCal recurrence rule string NOTE: Only supported by google and ics | | description | Information about the event | String | | location | Event location in words | String | | busy | Mark on calendar as busy? | Boolean | | guests | Emails of other guests | Array of emails (String) | | url | Calendar document URL | String |


  • Any one of the fields end, duration, or allDay is required.
  • The allowed units in duration are listed here:
  • The url field defaults to document.URL if a global document object exists. For server-side rendering, you should supply the url manually. Not all calendars support the guests and url fields.
  • If you don't pass the start and end time in UTC, Google will convert it to UTC but Outlook won't, so it's a good idea to use UTC when passing dates and times
  • There are some known issues in Office 365 because of which we can't generate a consistent link in all devices (#542)
