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 🙏

#Dateify-js

###Lightweight date and time library for JavaScript.

Offers functions for dealing with dates and times in the browser. This library is not necessarily meant as an alternative to moment.js, more that its small as possible while still meeting my needs.

##API

###dateify

  • dateify :: String -> Date
  • dateify :: Number -> Date
  • dateify :: Date -> Date
  • dateify :: [Number] -> Date

Converts parameters into a Date object. Can take any of the parameters that the JavaScript Date constructor will accept with a few additions: a subset of ISO 8601 formatted datestrings can be parsed, and it can take an array of Numbers and spread them for the constructor.

###deDateify

  • deDateify :: Date -> String

Converts a Date object into an ISO 8601 datestring.

###isLeapYear

  • isLeapYear :: Number -> Boolean

Will correctly identify whether or not any CE year is a leap year. Does not work for BCE years.

###toUTCDateString

  • toUTCDateString :: Date -> String

Same as deDateify but outputs a zulu time string.

###destructure

  • destructure :: Date -> [Number]

Performs the reverse operation of the Date constructor: takes a Date and returns an array of its numbers [yr, mon*, day, hr, min, sec], same position as the Date constructor takes them.

* Does not add 1 to the month, i.e. January is 0.

##Input Upgrades

Because not all browsers implement input type='date/time' dateify provides some functions to implement some basic validation/formatting on the passed-in input elements. Note that calling the function without an input argument will cause one to be created of the appropriate tag. Because I use Polymer frequently, I've added versions of these that work for paper-inputs:

###toDateInput

###toTimeInput

###toPaperDate

###toPaperTime

All have a signature of HTMLElement -> HTMLElement or Nil -> HTMLElement.

##NOTE

-When used with Polymer paper-inputs:

Polymer paper inputs will not behave correctly in chrome unless you declare the type attribute to be date before the element is completely upgraded (e.g. 'dom-change' event fired on an auto-binding template). If using with Polymer make sure to set type="date" in your markup (won't affect other browsers).
