httpd

A fast and easy-to-use web server, using the Deno native http server (hyper in rust). It serves static files & dirs, with arbitrary handling using an optional handler argument.

Example

import httpd from 'https://deno.land/x/httpd/mod.js'

httpd((req, headers) => {
  if (new URL(req.url).pathname.startsWith('/details/'))
    return new Response('You are asking for some details', { headers })
})

You can pass a 2nd optional opts hashmap/object argument to httpd() to customize.

Defaults

HTTP port 5000 – override with opts arg like: { port: 8888 } or CLI arg like: -p8888
CORS headers – override with opts arg like: { cors: false }
dir listings – override with opts arg like: { ls: false }
dotfiles are omitted from dir listings

If that pathname doesn’t map to a static file or dir (and get served directly), your handler() gets invoked.

You can return a Response object (Promise) or not return anything at all.

For the former case, we default the reply content-type to text/html.
- To override, use the optional 2nd argument headers to your handler, and change as desired, eg: headers.set('content-type', 'text/plain')
For the latter case, we’ll emit a 404 (lightly customized) page.

If your handler throws an exception, a general 500 page will be served.

NOTE: This httpd daemon does NOT show dotfiles in dir listings (on by default) – but it does serve a dotfile if the caller knows the file/dirname. Consider .dockerignore or similar for your project to avoid dotfiles in your deployed webdir if needed.
