viewportViewer :see_no_evil:

This is a simple drop-in utility to show viewport size in the lower right corner for development.

Usage

npm i viewportviewer --save-dev

yarn add viewportviewer --dev

Then include viewportviewer.js or ./dist/viewportviewer.min.js however you prefer. There's also a basic CSS file you can include for styling, viewportviewer.css or ./dist/viewportviewer.min.css. Alternatively, you can add your own CSS styling on the #viewportviewer selector:

#viewportviewer {
  font-size: 1.1rem;
  font-weight: bold;
  z-index: 9999;
  position: fixed;
  bottom: 0;
  right: 0;
  color: #ffffff;
  background: #071c2c;
  padding: 1.2rem;
  cursor: pointer;
}

You can also load the file(s) from unpkg:

<link rel="stylesheet" type="text/css" href="https://unpkg.com/viewportviewer@latest/dist/viewportviewer.min.css">

<script src="https://unpkg.com/viewportviewer@latest/dist/viewportviewer.min.js"></script>

Additionally, you can add whatever logic is needed for your stack in order to only run this in development and/or staging.
