Custom Notifier

To create a custom notifier you must have a struct that implements the ffnotifier.notifier interface.

import (
    ffclient "github.com/thomaspoignant/go-feature-flag"
    "github.com/thomaspoignant/go-feature-flag/ffnotifier"
    "sync"
)

// Your config object to create a new Notifier
type CustomNotifierConfig struct{}

// GetNotifier returns a notfier that implement ffnotifier.Notifier
func (c *CustomNotifierConfig) GetNotifier(config ffclient.Config) (ffnotifier.Notifier, error) {
    return &CustomNotifier{}, nil
}

type CustomNotifier struct{}
func (w *CustomNotifier) Notify(cache ffnotifier.DiffCache, waitGroup *sync.WaitGroup) {
    defer waitGroup.Done() // don't forget this line, if you don't have it you can break your notifications
    
    // ...
    // do whatever you want here
}
