/*
Package fcm provides message notification integration for Firebase Cloud Messaging (FCM).

Usage:

    package main

    import (
        "context"
        "log"

        "github.com/nikoksr/notify"
        "github.com/nikoksr/notify/service/fcm"
    )

    func main() {
        fcmSvc, err := fcm.New("server_api_key")
        if err != nil {
            log.Fatalf("fcm.New() failed: %s", err.Error())
        }

        fcmSvc.AddReceivers("deviceToken1")

        notifier := notify.New()
        notifier.UseServices(fcmSvc)

        // Use context.Background() if you want to send a simple notification message.
        ctx := context.Background()

        // Optionally, you can include additional data in the message payload by adding the corresponding value to the
        // context.
        ctxWithData := context.WithValue(ctx, fcm.DataKey, map[string]interface{}{
            "some-key":  "some-value",
            "other-key": "other-value",
        })

        // Optionally, you can specify a total of retry attempts per each message by adding the corresponding value to
        // the context.
        ctxWithDataAndRetries := context.WithValue(ctxWithData, fcm.RetriesKey, 3)

        err = notifier.Send(ctxWithDataAndRetries, "subject", "message")
        if err != nil {
            log.Fatalf("notifier.Send() failed: %s", err.Error())
        }

        log.Println("notification sent")
    }
