README

This package contains the notifications client written in the Go programming language. The notifications client is used by Go services or other Go code to communicate with the EdgeX support-notifications microservice (regardless of underlying implemenation type) by sending REST requests to the service's API endpoints.

How To Use

To use the support-notifications client package you first need to import the library into your project:

import "github.com/edgexfoundry/go-mod-core-contracts/v2/clients/notifications"

To send a notification you first need to get a NotificationsClient and then send a Notification struct:

		notification := notifications.Notification{
			Slug:        configuration.NotificationsSlug + strconv.FormatInt((time.Now().UnixNano()/int64(time.Millisecond)), 10),
			Content:     configuration.NotificationContent + name + "-" + string(action),
			Category:    notifications.SW_HEALTH,
			Description: configuration.NotificationDescription,
			Labels:      []string{configuration.NotificationLabel},
			Sender:      configuration.NotificationSender,
			Severity:    notifications.NORMAL,
		}

		notifications.GetNotificationsClient().SendNotification(notification)

This will send the notification to the notifications service.
