How to Display Toasts or Notices using Lightning : NotificationLibrary

By | June 28, 2021

In this blog, we will discuss on how to display messages via toast or notices using Lightning:NotificationLibrary component.


  • Lightning:NotificationLibrary component provides an easy way to display messages via toasts or notices.
  • However, Toast message helps in providing feedback to users. Above all, a toast message can be closed automatically after the predefined period of time has elapsed.
  • Notices can block the user’s entire screen until the user closes it manually. After that, it shall alert users about system-related issues and updates.

Create Lightning Component

LightningNotifications Component

  • Firstly, to display toast or notices using Lightning:NotificationLibrary component we have to include “<lightning:notificationsLibrary aura:id="notifyId"/>" tag in the component that triggers the notifications, where aura:id is a unique local ID.
  • Secondly, kindly note that only one tag is enough to display multiple notifications. Refer the below code to define the component.
    <lightning:notificationsLibrary aura:id="notifyId"/>
    <lightning:button name="notice" label="Display Notice" onclick="{!c.showNotice}"/>
    <lightning:button name="toast" label="Display Toast" onclick="{!c.showToast}"/>


  • Also, in order to create and display notice, we need to use “component.find('notifyId').showNotice()", where “notifyId" is  the aura:id of lightning:notificationsLibrary instance which we define in the above component.
  • Similarly, to create and display toast, we need to use “component.find('notifyId').showToast(),where “notifyId” is  the aura:id of lightning:notificationsLibrary instance which we define in the above component.
  • Kindly refer to the below code.
  	showNotice : function(component, event, helper) {
            "variant": "error",
            "header": "An Internal Server has occured!",
            "message": "There was a problem updating the record. Please contact your system administrator.",
            closeCallback: function() 
    showToast : function(component, event, helper) {
            "variant": "Success",
            "title": "Success!",
            "message": "Component Loaded successfully."
  • Here is the output, so now when the user clicks on the “Display Notice” button, a notice message popup will appear as shown in the below image.
