Routing configuration consists of routes, targets, config, and owner.
Preferably, an array of routes is added to the router. Each route defines a name, a pattern, and optionally one or more targets to which to navigate when the route has been matched. In the routes section, you define which patterns are available for navigation. Routes need to be defined in an array instead of an object, because their order in the array determines the sequence when matching against the browser hash.
The name of the route (unique within one router instance)
The pattern as hash part of the URL that matches the route
The navigation target as defined in the targets section
If you want to load multiple views/components at the same time, you can assign multiple targets (see Working with Multiple Targets).
If a target is configured for loading a component, you can enable the routing in the loaded component, see Enabling Routing in Nested Components.
The titleTarget to specify from which target the title is taken when multiple targets are displayed. If no titleTarget is defined, the first target that has a title is chosen (see Using the title Property in Targets).
The sequence of the routes in the routes definition is important. As soon as a pattern is matched, the following patterns are ignored. To prevent this for a specific route, you use the greedy parameter. If set to true, the route is always taken into account.
For more information, see API Reference: sap.m.routing.Router.
A target defines the view or component that is displayed. It is associated with one or more routes or it can be displayed manually from within the app. Whenever a target is displayed, the corresponding view or component is loaded and added to the aggregation configured with the controlAggregation option of the control. The target definition can contain the following parameters:
The target key
The type to specify whether the target is a view or a component
The name to specify the name of the view or component
Additional optional parameters
If you don’t specify a parameter, the default value is taken from the config section.
viewType (e.g. XML) which is valid only when the type is set to “View”
id of the view or component instance
A view or component instance is cached in OpenUI5 routing under the combination of its name and id. If there already is one instance created for a specific view or component with an id, this instance is reused if another target with the same name and id is displayed. If a new instance needs to be created instead of reusing the existing ones, assign the target a different id.
level
You can use different levels to define the navigation direction, for example the navigation from a lower view level to a higher view level leads to forward navigation. This is, for example, important for flip and slide transitions, where the slide animation should go from left to right or vice versa.
controlId of the control that is used as the parent to insert the view or component (e.g. app)
controlAggregation target aggregation of the control with controlId to which the view or component is added
The NavContainer control, for example, has an aggregation called Pages and the shell container has Content.
parent: the key of another target which a view is created and added before the target view or component is added
path: the namespace of the view or component
targetParent where the control with the controlId is located (see Working with Multiple Targets); this option is set automatically for the root view of a component if the router instance is instantiated by the component.
clearAggregation specifies whether the aggregation should be cleared before adding the new view instance.
When you use the sap.m.routing.Router the default is false, for sap.ui.core.routing.Router it is true.
When using sap.ui.ux3.Shell this value should be set to true, for sap.m.NavContainer to false to ensure that the correct content is shown.
transition defines how the transition happens; you can choose between slide (default), flip, fade, and show.
title contains either a static text or a valid binding syntax, e.g. to an i18n model, which is resolved under the binding context of the view (see Using the title Property in Targets)
Note:
You can also use targets without routes to call a view directly.For more information, see the tutorial Step 5: Display a Target Without Changing the Hash and Step 10: Implement “Lazy Loading”, and the sample Targets Without a Router in the Samples in the Demo Kit.
For more information, see API Reference: sap.m.routing.Router.
The config section contains the global router configuration and default values that apply for all routes and targets. The config section contains the following settings.
routerClass defines which router is used.
You can either use class sap.ui.core.routing.Router (default) or sap.m.routing.Router. If you use a sap.m control (such as NavContainer or SplitApp) in your app, you can benefit more from using sap.m.routing.Router because it not only loads the targets and places them in the corresponding container, but also triggers the animation for navigating to the right target.
Note:
The possible values for
routerClassaresap.ui.core.routing.Router,sap.m.routing.Router, or any other subclasses ofsap.ui.core.routing.Router.Compared to
sap.ui.core.routing.Router, thesap.m.routing.Routeris optimized for mobile apps and adds thelevel,transition, andtransitionParametersproperties, which can be specified for each route or target created bysap.m.routing.Router. ThetransitionParameterscan also be used for custom transitions. See the API Reference for more information.
The homeRoute defines the route whose target title is inserted as the first entry in the title history in the titleChanged event or in the return value of sap.ui.core.routing.Router.prototype.getTitleHistory. For more information, see section Initial title of the home page of Using the title Property in Targets.
The property contains the name of one of the routes that are defined in the routes section as value.
You can also define default values for all target parameters
async defines whether targets are loaded asynchronously; the default value is false. We recommend setting this parameter to true to improve performance.
Note:
A target with
type“Component” is only displayed with asynchronous loading.
Note:
If you use asynchronous loading, you cannot rely on the sequence of events that are fired during the load phase. If you follow our programming model with MVC, this should not be a problem.
Note:
If the
Component.jsimplements thesap.ui.core.IAsyncContentCreationinterface, the default value forasyncis set totrue, so noasyncconfig needs to be set in themanifest.json.
Using the bypassed parameter, you specify the navigation target that is used whenever no navigation pattern is matched. If you use this setting, you also have to define a corresponding target in the targets section.
For more information, see API Reference: sap.m.routing.Router.
The owner parameter defines the owner of all views that are created by the router. This is typically a UIComponent. This parameter is set automatically if the router instance is instantiated by a component.
{
metadata: {
routing: {
config: {
async: true
viewType: "XML",
path: "view",
controlId: "splitApp",
clearTarget: false,
bypassed: {
target: "notFound"
},
homeRoute: "home"
},
routes: [
{
pattern: "",
name : "home",
target: "home"
},
{
pattern: "category/{id}",
name: "category",
target: "category"
},
{
pattern: "category/{id}/product/{productId}",
name: "product",
target: ["category", "product"]
},
],
targets: {
category: {
type: "View",
name: "Category",
controlAggregation: "masterPages"
},
product: {
type: "View",
name: "Product",
controlAggregation: "detailPages",
},
home: {
type: "View",
name: "Home",
controlAggregation: "masterPages"
},
notFound: {
type: "View",
name: "NotFound",
controlAggregation: "detailPages",
parent: "home"
}
}
}
}
}
In this example, the Home view is always shown when the hash is empty. The Category view is shown when the hash matches the pattern category/{id}. Both, the Category and the Product view are shown when the hash matches the pattern category/{id}/product/{productId}, because both of them are added to the target property of the product route.
