I was working on a website in vanilla HTML + JS, and I missed one of the best feature provided by those quick start packages like create-react-app or the Vue CLI: reloading the page when I saved a file in the code editor.

The simplest way I found is to install browser-sync:

npm install -g browser-sync

then run it in your project folder:

browser-sync start --server --files "."

The above command watches all files in the current folder (and all subfolders) for changes, and launches a web server on port 3000, opening a browser window to connect to the server.

Any time you change a file, the browser will refresh.

Very useful while prototyping!
