listen()​

abstract listen(): this

Defined in: packages/core/src/router/AbstractRouter.ts:307

Registers event listeners at the client side window object allowing the router to capture user's history (history pop state - going "back") and page (clicking links) navigation.

The router will start processing the navigation internally, handling the user's navigation to display the page related to the URL resulting from the user's action.

Note that the router will not prevent forms from being submitted to the server.

The effects of this method can be reverted with unlisten. This method has no effect at the server side.

Returns​

this

This router.

Overrides​

Router.listen

redirect()​

redirect(url, options?, action?, locals?): void

Defined in: packages/core/src/router/AbstractRouter.ts:332

Redirects the client to the specified location.

At the server side the method results in responding to the client with a redirect HTTP status code and the Location header.

At the client side the method updates the current URL by manipulating the browser history (if the target URL is at the same domain and protocol as the current one) or performs a hard redirect (if the target URL points to a different protocol or domain).

The method will result in the router handling the new URL and routing the client to the related page if the URL is set at the client side and points to the same domain and protocol.

Parameters​

url​

string

The URL to which the client should be redirected.

options?​

Partial<RouteOptions>

The options overrides route options defined in the routes.js configuration file.

action?​

RouteAction

Returns​

void

This router.

Overrides​

Overrides​

Router.route

The router will stop processing the navigation internally, handling the user's navigation to display the page related to the URL resulting from the user's action.

Note that the router will not prevent forms from being submitted to the server.

The effects of this method can be reverted with unlisten. This method has no effect at the server side.

Returns​

this

This router.
