Installation

Manual installation

You can download the latest release binaries available in the releases section of the repository.

Warning Keep in mind that if you install it manually, you will not have the ability to update automatically when there is a new version of servant.

Package manager

In macOS/Linux environments you can install servant using Homebrew:

brew install planta7/tap/servant

Install from sources

$ git clone https://www.github.com/planta7/servant.git
$ cd servant
$ go build ./...

Note Requires GO >= 1.20

Binaries

You can download the binaries from the releases page, currently this is the only way to install it on Windows systems.

Usage

To start a server in the current path, simply run $ servant local. In addition to the TL;DR execution, there are also a number of options that you can configure to suit your needs:

Usage:
  servant local [path] [flags]

Aliases:
  local, l

Flags:
      --auth string        username:password for basic auth (default is empty)
      --auto-tls           Start with embedded certificate (default is false)
      --cert-file string   Path to certificate (default is empty)
  -c, --cors               Enable CORS (default is false)
  -e, --expose             Expose through localtunnel (default is false)
  -s, --subdomain          Subdomain (default is random)
  -h, --help               help for local
      --host string        Server host (default is empty)
      --key-file string    Path to key
  -l, --launch             Launch default browser (default is false)
  -p, --port int           Listen on port (default is random)

Global Flags:
      --config string   config file (default is ./servant and $HOME/.servant)
      --disable-tui     Disable TUI (default is false)
  -v, --verbose         verbose mode (default is false)

[!IMPORTANT] There is also the powerful remote command that allows you to expose a local server in the same way you do with ngrok and for which I have not yet been able to write documentation. You can see all the options by running server remote -h.

Examples

To start a local server on port 8080 and automatically launch the system's default browser use the following command:

servant local -p 8080 -l

servant will bind the server to the loopback address in addition to the private IP that is configured on the system's default interface. If you want to bind the server to a specific IP, use the command:

servant local --host 192.168.3.12

The above examples start an HTTP server, but if you need to launch an HTTPS server, you can easily do so by providing the certificate file and its key:

servant local --cert-file /path/to/cert-file --key-file /path/to/key-file

Or if you prefer, you can let servant generate a self-signed certificate and key randomly at startup.

servant local --auto-tls

If you are using embedded or self-signed certificates you will receive a security alert in the browser indicating that the certificate is not trusted, you can safely ignore the warning, or you can provide a valid certificate to servant.

Whatever the combination of parameters, --verbose or -v flag enables detailed output of what is happening on the server.

[!NOTE] Bonus tip! You can use flags in a more elegant way if you chain them together.

servant local -clvp 8080
# is equivalent to
servant local -c -l -v -p 8080
# and
servant local --cors --launch --verbose --port 8080

Configuration

You can configure servant using flags, but you also have other options:

• .servant configuration file (here is an example)
  • Current directory (local)
  • $HOME directory (global)
  • Specified by the flag --config
• Using environment variables
  • SERVANT_AUTH
  • SERVANT_AUTO_TLS
  • SERVANT_CERT_FILE
  • SERVANT_CORS
  • SERVANT_DISABLE_TUI
  • SERVANT_EXPOSE
  • SERVANT_HOST
  • SERVANT_KEY_FILE
  • SERVANT_LAUNCH
  • SERVANT_PORT
  • SERVANT_SUBDOMAIN

Priority for applying the value to parameters is as follows:

1. Flags
2. Environment variables
3. Configuration file
   1. Specified by --config
   2. Local
   3. Global
4. Defaults

The result will be a merge after applying the above order.

Note You can check the value of the parameters by starting servant with -v or --verbose.
