Chissel

Chissel is an SSE (Sever Sent Events) provider and broker that can be used with almost any http mux/router

Features

• Mux/router agnostic (provides single http handler func - works with stdlib mux, Chi, Gorilla etc.)
• Optional support for topics
• Optional support for multi-tenancy
• Optional authentication
• Pluggable logging

Installation

To install chissel, use go get:

go get github.com/go-andiamo/chissel

To update chissel to the latest version, run:

go get -u github.com/go-andiamo/chissel

Example

The following example is a simple SSE chat using stdlib mux (see _examples/muxchat)

package main

import (
    _ "embed"
    "github.com/go-andiamo/chissel"
    "io"
    "log"
    "net/http"
)

//go:embed index.html
var index []byte

func main() {
    sse, err := chissel.NewSse()
    if err != nil {
        log.Fatal(err)
    }
    mux := http.NewServeMux()
    mux.HandleFunc("GET /", func(w http.ResponseWriter, r *http.Request) {
        _, _ = w.Write(index)
    })
    mux.HandleFunc("POST /messages", func(w http.ResponseWriter, r *http.Request) {
        if r.Body == nil {
            return
        }
        data, _ := io.ReadAll(r.Body)
        sse.Broadcast(chissel.Event{
            Message: data,
        })
    })
    mux.HandleFunc("GET /messages", sse.Handler())

    _ = http.ListenAndServe(":8080", mux)
}
