Navigation Service in LWC(Lightning Web Components)


Navigation Service in LWC(Lightning Web Components)

Navigation Service in LWC(Lightning Web Components)

To navigate in Lightning Experience, Lightning Communities, and the Salesforce app, use the navigation service, lightning/navigation.

The lightning/navigation service is supported only in Lightning Experience, Lightning Communities, and the Salesforce app. It isn’t supported in other containers, such as Lightning Components for Visualforce, or Lightning Out. This is true even if you access these containers inside Lightning Experience or the Salesforce app. We can use navigation services in LWC to Navigate to Pages, Records, and Lists.

There are different types of navigation options available. Let’s discuss the basic one

Basic Navigation

Use the navigation service, lightning/navigation, to navigate to many different page types, like records, list views, and objects. Also use the navigation service to open files.

Instead of a URL, the navigation service uses a PageReference. A PageReference is a JavaScript object that describes the page type, its attributes, and the state of the page. Using a PageReference insulates your component from future changes to URL formats. It also allows your component to be used in multiple applications, each of which can use different URL formats.

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

Page type(String) and attributes(Object) are required parameters, state(Object) is optional parameter.

Use Navigation Service in LWC

Here are steps to use the navigation service

  1. First, we need to import the lightning/navigation module.
    1
    import { NavigationMixin } from 'lightning/navigation';
  2. Apply the NavigationMixin function to your component’s base class.
    1
    export default class MyCustomElement extends NavigationMixin(LightningElement) {}
  3. Create a plain JavaScript PageReference object that defines the page
  4. To dispatch the navigation request, call the navigation service’s [NavigationMixin.Navigate](pageReference, [replace])

    navigateNext() {
           this[NavigationMixin.Navigate]({
               type: 'standard__navItemPage',
               attributes: {
                   apiName: this.tabName,
               },
           });
       }

The NavigationMixin adds two APIs to your component’s class. Since these APIs are methods on the class, they must be invoked with this reference.

  • [NavigationMixin.Navigate](pageReference, [replace]): A component calls this[NavigationMixin.Navigate] to navigate to another page in the application.
  • [NavigationMixin.GenerateUrl](pageReference): A component calls this[NavigationMixin.GenerateUrl] to get a promise that resolves to the resulting URL. The component can use the URL in the href attribute of an anchor. It can also use the URL to open a new window using the window.open(url) browser API.

Now we can add this LWC component on the Account Record page.

  • Go to Account detail record page
  • Click Setup (Gear Icon) and select Edit Page.
  • Under Custom Components, find your navigationExampleLWC component and drag it
  •  on right-hand side top.
  • Click Save and activate.

 

We will get the following output
