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 🙏

@parallelogram-js/core

v0.7.20

Published

A lightweight, enhancement-first JavaScript framework for progressive web applications

Readme

@parallelogram-js/core adds behaviour to server-rendered HTML through data attributes and a small set of web components. Components load the first time a page uses them, and links swap the page in place instead of reloading it.

npm install @parallelogram-js/core

The package is ESM only and targets Baseline 2023 browsers: Chrome and Edge 120, Firefox 121, and Safari 17.2 or later.

The framework is optional. Any enhancement can be used on its own — import Toggle from '@parallelogram-js/core/components/Toggle', then Toggle.enhanceAll() mounts it on every matching element, with no framework and no build step beyond your bundler.

Versions and browser support

  • Releases follow semantic versioning from 1.0. Before it, any release may rename or remove something; each such change is marked Breaking in the changelog with what to change, and the upgrade guides carry the same list. 0.7.7 and 0.7.8 were patch releases with breaking changes, and an earlier version of this line said that never happened.
  • Where something is deprecated rather than removed outright, it is announced in the changelog and keeps working for at least one minor release and thirty days, whichever is longer, before it goes. The wall-clock half matters: 0.5.0 to 0.6.0 took six hours, and a window measured only in releases is no window at all when a release costs an afternoon.
  • The browser floor is Baseline 2023: Chrome and Edge 120, Firefox 121, and Safari 17.2 on macOS and iOS, or later. Older browsers aren't tested or supported.
  • Only the latest minor release line gets security fixes. See SECURITY.md for how to report a vulnerability.
