Upsite 
Upsite lets you start a local server without any configuration.
npx upsiteHTML, CSS, and JS files are automatically transformed using pHTML, PostCSS, and Babel.
Upsite automatically spins up a server and lets you start writing to files —
batteries included. Once started, Upsite creates a package.json file and a
public folder with HTML, CSS, and JS files inside of it. It also installs
Express, configuring it to intercept .html files for pHTML, .css files
for PostCSS, and .js files for Babel. It also creates a self-signed SSL
certificate for HTTPS and attempts to certify it on your machine.
