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 🙏

SWC plugin to inject data-source attributes into DOM elements

Readme

@vybe-adk/swc-dom-source

npm version License: MIT CI

SWC plugin that injects source location data attributes into DOM elements for debugging.

Installation

npm install @vybe-adk/swc-dom-source

Usage

Add the plugin to your Next.js config:

// next.config.js
module.exports = {
  experimental: {
    swcPlugins: [
      ["@vybe-adk/swc-dom-source", { attr: "data-source", exclude: ["components/ui"] }],
    ],
  },
};

Options

| Option | Type | Default | Description | |-----------|------------|-----------------|--------------------------------------------------| | attr | string | "data-source" | The attribute name to inject | | exclude | string[] | [] | File path patterns to exclude from transformation |

Output

The plugin adds a data attribute to host JSX elements (lowercase tags like div, span, etc.) with the format:

filename:line:column

Example output:

<div data-source="src/components/Button.tsx:15:4">Click me</div>

Compatibility

This plugin must match the swc_core version used by your framework. Using a mismatched version will cause runtime errors.

| swc_core version | Next.js version | Status | |---------------------|-----------------|-------------| | 35.x | 15.x | Supported | | 36.x+ | 16.x | Not yet supported |

This plugin currently uses swc_core v35.0.0, which aligns with Next.js 15. Next.js 16 ships a newer SWC version and is not yet supported.

Building from source

Requires Rust with the wasm32-wasip1 target:

rustup target add wasm32-wasip1
npm run build
