Members

enableTracing?: boolean

Makes the router log all its internal events to the console.

useHash?: boolean

Enables the location strategy that uses the URL fragment instead of the history API.

initialNavigation?: InitialNavigation

Disables the initial navigation.

errorHandler?: ErrorHandler

A custom error handler.

preloadingStrategy?: any

Configures a preloading strategy. See PreloadAllModules.

onSameUrlNavigation?: 'reload' | 'ignore'

Define what the router should do if it receives a navigation request to the current URL. By default, the router will ignore this navigation. However, this prevents features such as a "refresh" button. Use this option to configure the behavior when navigating to the current URL. Default is 'ignore'.

paramsInheritanceStrategy?: 'emptyOnly' | 'always'

Defines how the router merges params, data and resolved data from parent to child routes. Available options are:

• 'emptyOnly', the default, only inherits parent params for path-less or component-less routes.
• 'always', enables unconditional inheritance of parent params.
