RFC1436 Gopher Client for Deno, with basic support for Gopher+.

Example Usage

// Import the client.
import {GopherClient} from 'https://deno.land/x/gopher/mod.ts';

// Create a new GopherClient, optionally specifying the protocol version to use.
const client = new GopherClient({
  ProtocolVersion: GopherProtocol.RFC1436,
});

// Download the Gopher server's menu.
const menu = await client.downloadMenu({
  Hostname: 'gopher.example.com',
  // Optional: Port (default 70)
  // Optional: Selector (e.g. '/foo')
});

// To display the menu items.
for (const menuItem of menu.Items) {
  console.log(menuItem.toString());
}

// To download a single menu item - the response contains the body and header
// (if it was  Gopher+ response):
const gopherResponse = client.downloadItem(menuItem);

// If it was a text entry (use the MenuItem.Type field to check) then you can
// easily convert to a string.
const text = new TextDecoder().decode(gopherResponse.body);

Getting Gopher+ attributes

// Having previously obtained the menu item (see basic example), attributes can
// be retrieved like so:
client.populateAttributes(myMenuItem)
console.log(myMenuItem);

Results:

MenuItem {
  Type: '0',
  Name: 'A file',
  Selector: '/a file.txt',
  Hostname: 'gopher.example.com',
  Port: 70,
  Original: '0A file\t/a file.txt\tgopher.example.com\t70\t+',
  Attributes: Map {
    'ADMIN' => Map {
        'Admin' => 'Foo Bar <foobar@example.com>',
        'Mod-Date' => 'Sun Feb 21 20:19:18 2021 <20210221201918>'
      },
    'VIEWS' => Map { 'text/plain' => '<1k>' }
  }
}
