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 🙏

ep_embedmedia_tweaks

v0.1.2

Published

Fork of ep_embedmedia with stricter sanitization and additional UI/UX improvements for Etherpad.

Readme

ep_embedmedia_tweaks

Privacy and usability-focused media embeds for Etherpad. This package is a maintained fork of ep_embedmedia with stricter input validation, privacy-enhanced YouTube handling, and updated editor integration.

Features

  • Toolbar dialog for inserting media embeds
  • Direct URL support for YouTube and Vimeo
  • Automatic conversion of YouTube URLs to youtube-nocookie.com
  • Sanitized iframe input for other HTTP(S) providers
  • Sandboxed iframe output with scripts and unsupported markup removed
  • Persistent embed attributes during collaborative editing

Installation

From the Etherpad directory:

pnpm run plugins i ep_embedmedia_tweaks

Restart Etherpad after installation. This release supports Etherpad 3.3.2 and later 3.x releases on Node.js 20 or newer.

Usage

Choose the video toolbar button and provide one of the following:

  • a YouTube URL;
  • a Vimeo URL; or
  • complete iframe markup from another HTTP(S) provider.

Direct URL conversion is intentionally limited to YouTube and Vimeo. Other providers must supply iframe markup, which is filtered through the plugin's allowlist-based sanitizer before insertion.

Embedding third-party content still allows that provider to receive browser requests. Review permitted providers and their privacy policies for your deployment.

Export support

This plugin does not register Etherpad export hooks. Embed attributes remain available to normal content collection, but specialized HTML or document-export rendering is outside the supported surface.

Development

pnpm install --frozen-lockfile
pnpm test
pnpm lint
