mailto:copy

Chrome extension that intercepts mailto: links and copies the email address to the clipboard instead of opening the system email app.

Load locally

1. Open chrome://extensions.
2. Enable Developer mode.
3. Click Load unpacked.
4. Select this folder.

Behavior

• Captures mailto: link activation in the capture phase.
• Prevents the browser's default email-client launch.
• Copies just the email address, not query params like subject= or body=.
• Shows a small toast confirming the copy action.

Build package

1. Run npm run build.
2. Find the release zip in dist/.

The build script will:

• Regenerate icons/icon-16.png, icons/icon-32.png, icons/icon-48.png, and icons/icon-128.png from logo.svg.
• Assemble a clean extension package.
• Create a versioned zip named like dist/mailto-copy-v1.0.0.zip.

Release

1. Update the version in manifest.json.
2. Run npm run build.
3. Open chrome://extensions and use Load unpacked on this folder for a final smoke test.
4. Verify the icon appears in the extensions page and the extension still copies mailto: addresses correctly.
5. Open the Chrome Web Store Developer Dashboard.
6. Upload the zip from dist/.
7. Fill in or confirm the store listing details:
   • Extension name and description
   • At least one screenshot
   • Category and language
   • Privacy disclosures and single-purpose justification, if requested by the dashboard
8. Submit the new item or updated version for review.

Notes for publishing

• Chrome Web Store expects a 128x128 icon in the package; this repo now generates it automatically from logo.svg.
• The store listing may also ask for larger promotional assets, which are separate from the extension package icons.
