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 🙏

Viewporter

Tools for working with all sorts of browser viewports.

Tools Included

getBodyOffset

Gets the absolute offset of the body, relative to the document.

Useful for adjusting absolute positions to suit different body positions.

getElementOffset

Gets the absolute offset of an element passed to it, relative to the body.

Useful for adjusting absolute positions to suit different element positions.

getMobileScaleFactor

Like getScaleFactor, but returns 1 on devices where isDesktopSiteInMobileViewport returns false.

(We use this in Bugherd to scale our UI to fit mobile browsers when shown on desktop sites)

getScaleFactor

Gets the scaling factor of the current browser. This function doesn't distinguish between a mobile browser's viewport and a desktop browser with developer tools or a sidebar. For desktop compatibility, use getMobileScaleFactor.

getScreenWidth

Returns the normalised screen width, no matter the orientation of the device, in pixels.

getViewportCoordinates

Gets the absolute offset of the current browser viewport, relative to the body.

isDesktopSiteInMobileViewport

Tests if the screen size is greater than the inner width of the window. In these cases, it is assumed that the browser is a mobile browser.
