A simple zero-configuration command-line HTTP files server. Like Python's SimpleHTTPServer but scalable. Сan easily handle thousands of simultaneous connections.

Implemented in Clojure with Aleph and Netty. Mostly as an example. It's still skillful and handy tho'. There's even nothing wrong with putting it to production.


Run in the directory you want to serve:

clj -Sdeps '{:deps {nasus {:mvn/version "0.1.5"}}}' -m http.server

Or specify custom port:

clj -Sdeps '{:deps {nasus {:mvn/version "0.1.5"}}}' -m http.server 8001


  • Plain text & HTML directory listings based on "Accept" header
  • Automatic mime-type detection
  • Streaming and chunked encoding for large files
  • Keep-alive and slow requests handling
  • Transparent content compression (gzip, deflate)
  • Cache control and "Last-Modified"
  • CORS headers

In development:

  • Range queries support
  • List of files & directories to exclude from serving
