 serve -h

  serve - Static file serving and directory listing

  USAGE

    $ serve --help
    $ serve --version
    $ serve folder_name
    $ serve [-l listen_uri [-l ...]] [directory]

    By default, serve will listen on 0.0.0.0:3000 and serve the
    current working directory on that address.

    Specifying a single --listen argument will overwrite the default, not supplement it.

  OPTIONS

    --help                              Shows this help message

    -v, --version                       Displays the current version of serve

    -l, --listen listen_uri             Specify a URI endpoint on which to listen (see below) -
                                        more than one may be specified to listen in multiple places

    -p                                  Specify custom port

    -s, --single                        Rewrite all not-found requests to `index.html`

    -d, --debug                         Show debugging information

    -c, --config                        Specify custom path to `serve.json`

    -L, --no-request-logging            Do not log any request information to the console.

    -C, --cors                          Enable CORS, sets `Access-Control-Allow-Origin` to `*`

    -n, --no-clipboard                  Do not copy the local address to the clipboard

    -u, --no-compression                Do not compress files

    --no-etag                           Send `Last-Modified` header instead of `ETag`

    -S, --symlinks                      Resolve symlinks instead of showing 404 errors

    --ssl-cert                          Optional path to an SSL/TLS certificate to serve with HTTPS
                                        Supported formats: PEM (default) and PKCS12 (PFX)

    --ssl-key                           Optional path to the SSL/TLS certificate's private key
                                        Applicable only for PEM certificates

    --ssl-pass                          Optional path to the SSL/TLS certificate's passphrase

    --no-port-switching                 Do not open a port other than the one specified when it's taken.

  ENDPOINTS

    Listen endpoints (specified by the --listen or -l options above) instruct serve
    to listen on one or more interfaces/ports, UNIX domain sockets, or Windows named pipes.

    For TCP ports on hostname "localhost":

      $ serve -l 1234

    For TCP (traditional host/port) endpoints:

      $ serve -l tcp://hostname:1234

    For UNIX domain socket endpoints:

      $ serve -l unix:/path/to/socket.sock

    For Windows named pipe endpoints:

      $ serve -l pipe:\\.\pipe\PipeName

$ npm install -g live-server

$ live-server -h
Usage: live-server [-v|--version] [-h|--help] [-q|--quiet] [--port=PORT] [--host=HOST] [--open=PATH] [--no-browser] [--browser=BROWSER] [--ignore=PATH] [--ignorePattern=RGXP] [--no-css-inject] [--entry-file=PATH] [--spa] [--mount=ROUTE:PATH] [--wait=MILLISECONDS] [--htpasswd=PATH] [--cors] [--https=PATH] [--https-module=MODULE_NAME] [--proxy=PATH] [PATH]

这个live-server有点特色：

在静态网站的根目录里，运行，比如live-server --port=2345 ，就会自动打开浏览器，访问

http://127.0.0.1:2345/
