Add/Edit URL parameters in LWC

Hello Devs,
Today I would like to explain to you how we can work with navigation parameters in Lightning Web Components.
Let’s get started!


I created a simple community page with custom navigation. When the user clicks on the navigation item c__page param in the URL will change. Based on URL c__page param highlighted navigation item change and Current Page information display different values.


LWC Code



    <lightning-vertical-navigation selected-item={newPageId}>
        <lightning-vertical-navigation-section label="Navigation" selected-item={newPageId}>
            <template for:each={navigationItems} for:item="navigationItem">
                <lightning-vertical-navigation-item key={navigationItem.pageId} label={navigationItem.label} name={navigationItem.pageId} onclick={handleNavigate}></lightning-vertical-navigation-item>

    <p>Current Page is <strong>{newPageId}</strong></p>



import { LightningElement, wire } from 'lwc';
import { CurrentPageReference, NavigationMixin } from 'lightning/navigation';

    { label: 'Home', pageId: 'home', isCurrentPage: false },
    { label: 'PageA', pageId: 'pageA', isCurrentPage: false },
    { label: 'PageB', pageId: 'pageB', isCurrentPage: false },
    { label: 'PageC', pageId: 'pageC', isCurrentPage: false },

export default class LwcNavigation extends NavigationMixin(LightningElement) {
    newPageId = 'home';
    navigationItems = NAVIGATION_ITEMS;

    setCurrentPageReference(currentPageReference) {
        if (currentPageReference) {
            this.currentPageReference = currentPageReference;

    get newPageReference() {
        return Object.assign({}, this.currentPageReference, {
            state: Object.assign({}, this.currentPageReference.state, this.newPageReferenceUrlParams)

    get newPageReferenceUrlParams() {
        return {
            c__page: this.selectedPageId

    setCurrentPageIdBasedOnUrl() {
        this.newPageId = this.currentPageReference.state.c__page;

    handleNavigate(event) {
        this.selectedPageId =;


    navigateToNewPage() {
            false // if true js history is replaced without pushing a new history entry onto the browser history stack
        );        // if false new js history entry is created. User will be able to click browser back/forward buttons
  • Line 16: Our Navigation is dynamically created based on NAVIGATION_ITEMS created before class declaration.
  • Line 19: setCurrentPageReference method is fire every time that c__page will change. We can use it to set the current pageId in Line 39.
  • Line 27: “The currentPageReference property is read-only. To navigate to the same page with a modified state, copy the currentPageReference and modify the copy.
  • Line 34: newPageReferenceUrlParams is used to prepare new states in URL.
    Remember!state properties must use a namespace prefix followed by two underscores, __. If the component isn’t part of a managed package, use c for the namespace prefix. If the component is part of a managed package, use the package’s namespace. To delete a value from the state object, define it as undefined.
  • Line 51: ‘replace’ argument – if false page state will change with pushing a new history entry into the browser history stack. It allows working with back/forward buttons.


As you can see, working with URL parameters in Lightning Web Components is not hard. The above approach allows us to create quite a nice Single Page Application (SPA) using standard salesforce NavigationMixin functionality.
We can also use it to generate page links, which improve User Experience, not just replace page content.
