Simple eventbus lib in Go

This project lets you publish and subscribe events easily.

To download:

go get github.com/Shibbaz/GOEventBus

Quick Start

Let's make a pub/sub application:

1. Create a project

mkdir demo
cd demo
go mod init demo

2. Add main.go

package main

import (
	"fmt"

	gbus "github.com/Shibbaz/GOEventBus"
)

// the message entity to be dispatched
type HouseWasSold struct{}

func main() {
	dispatcher := &gbus.Dispatcher{
		"main.HouseWasSold": func(m map[string]any) {
			fmt.Printf("dispatch: %v\n",m)
		},
	}
	eventstore := gbus.NewEventStore(dispatcher)
	eventstore.Publish(gbus.NewEvent(
				HouseWasSold{},
				map[string]any{
					"price": 1 * 100,
				},
			))
	eventstore.Run()
}

3. Get the dependency

go get github.com/Shibbaz/GOEventBus@v0.1.6.2

4. Run the project

go run ./
