schuko

schuko

Subscribe a websocket client to a Redis PubSub channel.

Server setup

Here's a minimal server implementation using schuko:

package main

import (
	"github.com/dejan/schuko"
	"net/http"
)

func main() {

	// configure schuko if needed
	// schuko.RedisUrl = ":6379"

	err := http.ListenAndServe(":4000", schuko.NewHandler())
	if err != nil {
		panic(err.Error())
	}
}

Subscribe

Subscribe with plain old WebSocket API.

var ws = new WebSocket("ws://localhost:4000/hacienda")
ws.onmessage = function(e) { console.log(e.data); }

WebSocket path (in this case "/hacienda") is the channel you're subscribing to.

Publish

Publish messages through Redis.

$ redis-cli 
127.0.0.1:6379> publish /hacienda "Hey Gringo!"
