notify-link-clicks-i18n

What it does

This extension includes:

• a content script, "content-script.js", that is injected into all pages
• a background script, "background-script.js"

The content script listens for clicks in the page it's attached to. If a click is on a link, the content script sends the link's href to the background script.

The background script listens for this message. When the background script receives the message, it displays a notification containing the href.

The notification's content, as well as the extension's name and description, are localized into German, Dutch, and Japanese, as well as the default en-US.

What it shows

• how to inject content scripts declaratively using manifest.json
• how to send messages from a content script to a background script
• how to display system notifications using the notifications API
• how to use the internationalization (i18n) system
