ion-router

Contents

The router is a component for handling routing inside vanilla and Stencil JavaScript projects.

note

Note: this component should only be used with vanilla and Stencil JavaScript projects. For Angular projects, use ion-router-outlet and the Angular router.

Apps should have a single ion-router component in the codebase. This component controls all interactions with the browser history and it aggregates updates through an event system.

ion-router is just a URL coordinator for the navigation outlets of ionic: ion-nav, ion-tabs, and ion-router-outlet.

That means the ion-router never touches the DOM, it does NOT show the components or emit any kind of lifecycle events, it just tells ion-nav, ion-tabs, and ion-router-outlet what and when to "show" based on the browser's URL.

In order to configure this relationship between components (to load/select) and URLs, ion-router uses a declarative syntax using JSX/HTML to define a tree of routes.

Interfaces

RouterEventDetail

interface RouterEventDetail {
from: string | null;
redirectedFrom: string | null;
to: string;
}

RouterCustomEvent

While not required, this interface can be used in place of the CustomEvent interface for stronger typing with Ionic events emitted from this component.

interface RouterCustomEvent extends CustomEvent {
detail: RouterEventDetail;
target: HTMLIonRouterElement;
}

Usage

<ion-router>
<ion-route component="page-tabs">
<ion-route url="/schedule" component="tab-schedule">
<ion-route component="page-schedule"></ion-route>
<ion-route url="/session/:sessionId" component="page-session"></ion-route>
</ion-route>

<ion-route url="/speakers" component="tab-speaker">
<ion-route component="page-speaker-list"></ion-route>
<ion-route url="/session/:sessionId" component="page-session"></ion-route>
<ion-route url="/:speakerId" component="page-speaker-detail"></ion-route>
</ion-route>

<ion-route url="/map" component="page-map"></ion-route>
<ion-route url="/about" component="page-about"></ion-route>
</ion-route>

<ion-route url="/tutorial" component="page-tutorial"></ion-route>
<ion-route url="/login" component="page-login"></ion-route>
<ion-route url="/account" component="page-account"></ion-route>
<ion-route url="/signup" component="page-signup"></ion-route>
<ion-route url="/support" component="page-support"></ion-route>
</ion-router>

Properties

root

DescriptionThe root path to use when matching URLs. By default, this is set to "/", but you can specify an alternate prefix for all URL paths.
Attributeroot
Typestring
Default'/'

useHash

DescriptionThe router can work in two "modes": - With hash: /index.html#/path/to/page - Without hash: /path/to/page

Using one or another might depend in the requirements of your app and/or where it's deployed.

Usually "hash-less" navigation works better for SEO and it's more user friendly too, but it might requires additional server-side configuration in order to properly work.

On the other side hash-navigation is much easier to deploy, it even works over the file protocol.

By default, this property is true, change to false to allow hash-less URLs.
