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 🙏

Browser parser and runtime for HyperMap APIs

Readme

HyperMap Shim

Browser parser and runtime for HyperMap. Parses HyperMap JSON responses and executes their embedded scripts, turning API data into living, reactive objects in the browser.

HyperMap is a JSON format for REST APIs that uses a single reserved key, #, to carry hypermedia controls and executable scripts. The shim is what makes that work in a browser — it reads the JSON, builds the HyperMap tree, and runs any scripts the server included.

For full documentation, see hypermap.dev/docs.

Install

npm install @hypermap/shim

Or load from a CDN:

<script type="module" src="https://cdn.jsdelivr.net/npm/@hypermap/[email protected]/+esm"></script>

Usage

Serve your HyperMap JSON as an HTML page with the shim and the data in a <pre> tag (which is the default rendering for JSON content types in Chrome and Safari):

<!DOCTYPE html>
<html>
  <head>
    <script type="module" src="https://cdn.jsdelivr.net/npm/@hypermap/[email protected]/+esm"></script>
  </head>
  <body>
    <pre>{"#": {"scripts": ["/my-script.js"]}, "hello": "world"}</pre>
  </body>
</html>

Development

The repo's Caddyfile serves this directory on localhost:4000 with HTTPS. Start Caddy from the repo root:

caddy run

Tests are browser-based — open tests/index.html after starting Caddy.
