Redis Watcher is a [Redis](http://redis.io) watcher for [Casbin](https://github.com/casbin/casbin).

## Installation

    go get github.com/casbin/redis-watcher/v2

## Simple Example

```go

package main

import (

	"log"

	"github.com/casbin/casbin/v2"

	rediswatcher "github.com/casbin/redis-watcher/v2"

	"github.com/redis/go-redis/v9"

)

func updateCallback(msg string) {

	log.Println(msg)

}

func main() {

	// Initialize the watcher.

	// Use the Redis host as parameter.

	w, _ := rediswatcher.NewWatcher("localhost:6379", rediswatcher.WatcherOptions{

		Options: redis.Options{

			Network:  "tcp",

			Password: "",

		},

		Channel:    "/casbin",

		// Only exists in test, generally be true

		IgnoreSelf: false,

	})

	// Or initialize the watcher in redis cluster.

	// w, _ := rediswatcher.NewWatcherWithCluster("localhost:6379,localhost:6379,localhost:6379", rediswatcher.WatcherOptions{

	// 	ClusterOptions: redis.ClusterOptions{

	// 		Password: "",

	// 	},

	// 	Channel: "/casbin",

	// 	IgnoreSelf: false,

	// })

	// Initialize the enforcer.

	e, _ := casbin.NewEnforcer("examples/rbac_model.conf", "examples/rbac_policy.csv")

	// Set the watcher for the enforcer.

	_ = e.SetWatcher(w)

	// Set callback to local example

	_ = w.SetUpdateCallback(updateCallback)

	

	// Or use the default callback

	// _ = w.SetUpdateCallback(rediswatcher.DefaultUpdateCallback(e))

	// Update the policy to test the effect.

	// You should see "[casbin rules updated]" in the log.

	_ = e.SavePolicy()

	// Only exists in test

	fmt.Scanln()

}
