Navigation Service in Lightning Web Components | Mixin

The Lightning navigation service allows you to navigate in Lightning Experience, Lightning Communities and the Salesforce app. To generate a URL or navigate to a page reference, use the lightning-navigation service wire adapters and functions.

PageReference is a JavaScript object that describes the page type, its attributes, and the state of the page.

Step 1) Import lightning/navigation
import { NavigationMixin } from 'lightning/navigation';

Step 2) Apply the NavigationMixin function to your component’s base class.

export default class MyCustomElement extends NavigationMixin(LightningElement) {

Step 3) Call the navigation service’s [NavigationMixin.Navigate] function to dispatch the navigation request and open the New Course Delivery modal dialog.

onAddNewDelivery() {
         type: 'standard__objectPage',
         attributes: {
             objectApiName: 'Student__c',
             actionName: 'new'

What is a Mixin?

A mixin lets us add functionality to a class without extending it. Useful when a class already extends a parent class, because a class can only extend a single parent.
