s4d

Minimal web development server with live reload.

Installation

npm install s4d --save-dev # project local installation (preferred)
npm install s4d --global # global installation

Usage

s4d [options] <webroot>

  --help, -h      Show this help.
  --host <host>   Set hostname. Default is "localhost".
                  Set "0.0.0.0" to expose over network.
  --port <port>   Set port. Default is 8080.
  --spa           Single-page application mode.
                  Serves /index.html for URLs that cannot be resolved to a file.

Examples:

s4d public
s4d --port 3000 public
s4d --port 3000 --spa public
s4d --port 3000 --host 0.0.0.0 --spa public # Expose over network

When installed locally in a project, run with npx s4d [args...], unless running from an npm script.

Live Reload Behavior

When a file under webroot is modified, attempts to reload stylesheets and images in-place if they match the modified file. In all other cases, a hard page reload is triggered.
