Navigation in LWC

Navigation in LWC :

There are a few steps to navigate from LWC :

1. import {NavigationMixin } from ‘lightning/navigation;
2. Apply the navigationMixin to the component’s base class to gain access t its APIs.

• export default class NavigationExample extends NavigationMixin (Lightning element)

1. NavigationMixin has two methods :

• Navigate
• GenerateURL

Limitations of NavigationMixin :

Lightning Navigation doesn’t work if we are using LWC

• inside visualforce page.
• inside aura component.

We will see one example of Navigate, let’s create a component to navigate to the record detail page from LWC.

ContactCreateForm.html:

<template>
	<lightning-card>
		<lightning-record-form
		object-api-name={objectApiName}
		fields={fields}
		onsuccess={handleSuccess}>
		</lightning-record-form>
	</lightning-card>
</template>        

ContactCreateForm.js :

import { LightningElement } from  'lwc';
import { ShowToastEvent } from  'lightning/platformShowToastEvent';
import CONTACT_OBJECT from  '@salesforce/schema/Contact';
import FIRST_NAME from  '@salesforce/schema/Contact.FirstName';
import LAST_NAME from  '@salesforce/schema/Contact.LastName';
import EMAIL_FIELD from  '@salesforce/schema/Contact.Email';
import { NavigationMixin } from  'lightning/navigation';
export  default  class ContactCreator extends NavigationMixin (LightningElement) {
objectApiName = CONTACT_OBJECT;
fields = [FIRST_NAME, LAST_NAME, EMAIL_FIELD];
handleSuccess(event) {
	const toastEvent = new ShowToastEvent({
	title: "Contact created",
	message: "Record ID: " + event.detail.id,
	variant: "success"
	});
	this.dispatchEvent(toastEvent);
	this.navigateToNewContactPage(event.detail.id);
}
navigateToNewContactPage(contactId) {
		this[NavigationMixin.Navigate]({
		type: 'standard__recordPage',
			attributes: {
			recordId: contactId,
			objectApiName: 'Contact',
			actionName: 'view'
			}
		});
	}
}
