Abstract Class: Router

Defined in: packages/core/src/router/Router.ts:107

The router manages the application's routing configuration and dispatches controllers and views according to the current URL and the route it matches.

Extended by​

Constructors​

Constructor​

new Router(): Router

Returns​

Router

Methods​

add()​

add(name, pathExpression, controller, view, options?): Router

Defined in: packages/core/src/router/Router.ts:168

Adds a new route to router.

Parameters​

name​

string

The unique name of this route, identifying it among the rest of the routes in the application.

pathExpression​

string

A path expression specifying the URL path part matching this route (must not contain a query string), optionally containing named parameter placeholders specified as :parameterName. The name of the parameter is terminated by a forward slash (/) or the end of the path expression string. The path expression may also contain optional parameters, which are specified as :?parameterName. It is recommended to specify the optional parameters at the end of the path expression.

controller​

AsyncRouteController

The full name of Object Container alias identifying the controller associated with this route.

view​

AsyncRouteView

The full name or Object Container alias identifying the view class associated with this route.

options?​

Partial<RouteOptions>

Additional route options, specified how the navigation to the route will be handled. The onlyUpdate can be either a flag signalling whether the current controller and view instances should be kept if they match the ones used by the previous route; or a callback function that will receive the previous controller and view identifiers used in the previously matching route, and returns a boolean representing the value of the flag. This flag is disabled by default. The autoScroll flag signals whether the page should be scrolled to the top when the navigation takes place. This flag is enabled by default.

Defined in: packages/core/src/router/Router.ts:460

Tests, if possible, whether the specified error was caused by the client's action (for example wrong URL or request encoding) or by a failure at the server side.

Parameters​

reason​

The encountered error.

Error | Error

Returns​

boolean

true if the error was caused the action of the client.


isRedirection()​

listen()​

listen(routerRoot?): Router

Defined in: packages/core/src/router/Router.ts:304

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.

Parameters​

routerRoot?​

EventTarget

Returns​

Router

This router.


redirect()​

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

Defined in: packages/core/src/router/Router.ts:358

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

An action object describing what triggered this routing.

locals?​

RouteLocals

The locals param is used to pass local data between middlewares.

Returns​

void


remove()​

remove(name): Router

Defined in: packages/core/src/router/Router.ts:198

Removes the specified route from the router's known routes.

Parameters​

name​

string

The route's unique name, identifying the route to remove.

Returns​

Router

This router.


route()​

route(path, options?, action?, locals?): Promise<void | UnknownParameters>

Defined in: packages/core/src/router/Router.ts:398

Routes the application to the route matching the providing path, renders the route page and sends the result to the client.

Parameters​

path​

string

The URL path part received from the client, with optional query.

options?​

Partial<RouteOptions>

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

action?​

An action object describing what triggered this routing.

locals?​

RouteLocals

The locals param is used to pass local data between middlewares.

Returns​

Promise<void | UnknownParameters>

A promise resolved when the error has been handled and the response has been sent to the client, or displayed if used at the client side.


unlisten()​

unlisten(): Router

Defined in: packages/core/src/router/Router.ts:325

Unregisters 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 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​

Router

This router.


unlistenAll()​

unlistenAll(): Router

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