ion-router
Contents
The router is a component for handling routing inside vanilla and Stencil JavaScript projects.
note
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.
Basic Usage
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>

Properties
root
Description | The root path to use when matching URLs. By default, this is set to "/", but you can specify an alternate prefix for all URL paths. |
Attribute | root |
Type | string |
Default | '/' |
useHash
Description | The 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. |
Attribute | use-hash |
Type | boolean |
Default | true |
Events
Name | Description |
---|---|
ionRouteDidChange | Emitted when the route had changed |
ionRouteWillChange | Event emitted when the route is about to change |
Methods

Signature | back() => Promise<void> |
push
Description | Navigate to the specified path. |
Signature | push(path: string, direction?: RouterDirection, animation?: AnimationBuilder) => Promise<boolean> |
