eventkit

Overview

The eventkit package provides a simple event-driven programming mechanism in Go. It allows you to create and manage events, subscribe to events using struct methods or functions, and trigger events with optional data.

Usage

Creating a new event instance

To create a new event instance, use the New() function:

eventInstance := eventkit.New()

Subscribing to an event

Using struct methods

To subscribe to an event using struct methods, use the Subscribe() function. It takes a struct instance as the payload and automatically registers all methods starting with a specified prefix (default: "On") as event listeners.

type MyEventPayload struct {
	// struct fields
}

func (m *MyEventPayload) OnEventName() {
	// event handler logic
}

// Subscribe to the event
eventInstance.Subscribe(&MyEventPayload{})

Using functions

To subscribe to an event using a function, use the SubscribeFunc() function. Provide a unique listener identifier and the callback function.

func myEventListener(data ...interface{}) {
	// event handler logic
}

// Subscribe to the event
eventInstance.SubscribeFunc("myListener", myEventListener)

Triggering an event

To trigger an event, use the Trigger() function. Provide the name of the event and optional data as arguments.

err := eventInstance.Trigger("eventName", eventData)
if err != nil {
	// handle error
}

Note: The package utilizes various external dependencies, such as logrus, golang.org/x/text/cases, and sync, among others.
