Quick Start

The following code defines a function make-remote-call that uses a circuit breaker named :some-name and stored in the default registry. If the circuit breaker does not already exist, one is created.

(ns myproject.some-client
  (:require [clj-http.client :as http]
            [resilience4clj.circuit-breaker :refer [with-circuit-breaker]])

(defn make-remote-call []
  (with-circuit-breaker :some-name
    (http/get "https://www.example.com")))

Refer to the configuration guide for more information on how to configure the default registry as well as individual circuit breakers.

Refer to the usage guide for more information on how to use circuit breakers to protect code as well as how to manually manage the state on a circuit breaker.
