Installing the Vue DevTools
You can install the DevTools as a Chrome extension via the Google Chrome Web Store or as an add-on for Firefox.
If Chrome or Firefox is not part of your development environment or workflow, you can also download it as a standalone Electron application via NPM.
$
npm install -g @vue/devtools
You can also install it locally as a dependency for your project:
$
npm install @vue/devtools --save-dev
