warp is a super-easy, composable, web server framework for warp speeds. Thanks to its Filter system, warp provides these out of the box:

  • Path routing and parameter extraction
  • Header requirements and extraction
  • Query string deserialization
  • JSON and Form bodies
  • Static Files and Directories
  • Websockets
  • Access logging

The main concept in warp is the Filter, which allows composition to describe various endpoints in your web service. Besides this powerful trait, warp comes with several built in filters, which can be combined for your specific needs.
