Liberator is a Clojure library designed for building RESTful web APIs in a principled, declarative manner. It abstracts HTTP semantics into resource constructs driven by representational state transfer, allowing deep control over HTTP behavior and content negotiation. Liberator used to be known as compojure-rest. It got renamed in July 2012. Liberator is loosely modeled after WebMachine and shares the same aims as Bishop. The examples in this document rely on you installing Leiningen 2.

Features

  • Declarative, resource-centric APIs modeled after REST principles
  • Automates HTTP protocol concerns, including headers, content negotiation, and proper response codes
  • Supports declarative decision points using a state machine-like approach
  • Easily integrate with Ring-compatible web servers and middleware
  • Includes tutorial and documentation for developer guidance
  • Maintained by a community of contributors and used widely in Clojure REST development
