Ever used Browsersync? If you’ve used Sage you’ve likely used it since we moved from LiveReload.
Anyways… assuming you have node/npm available at the command line you can install Browsersync globally like so:
$ npm install -g browser-sync
Once you’ve done that, navigate to a folder with an
index.html file in it (maybe it has some css, js, or images too!) and type this:
$ browser-sync start --server --files "*.html"
That will start a web server at
http://localhost:3000 and open your browser to it. It will also watch html files in that folder for changes (that last parameter defines what to watch).
