cgi

Common Gateway Interface (CGI) in Gleam.

CGI is not commonly used these days, but there scenarios where it is still a good choice. As CGI programs only run when there is a request to handle they do not use any system resources when there is no traffic. This makes them very efficient for low traffic websites.

gleam add cgi

import cgi
import gleam/string

pub fn main() {
  use request <- cgi.handle_request
  let headers = [#("content-type", "text/plain")]
  let body = "Hello! You send me this request:\n\n" <> string.inspect(request)
  Response(201, headers, body)
}

You may wish to compile your Gleam program to an escript to be run by your CGI server.

Thank you to Steven vanZyl for plug_cgi, which was used as a reference. Why is there so little information on the CGI protcol online these days?
