A browser extension that allows you to copy a link's text via the context menu

You can always browse through the source code (in src).

npm i # In case it's not done already
npm run build # Build the extension (in dist)
npm run webext:build # Package the WebExtension (using dist as the source directory, putting the zip archive into web-ext-artifacts)

After these commands, you will have the built (and minified) code inside the dist folder, as well as a zip of said code inside web-ext-artifacts (named copy-link-text-<manifest version>.zip, e.g. copy-link-text-1.0.0.zip).
