You have to keep three things in mind when creating a page:

- it requires a build method,
- you can build the page and add a component to the page within the overridable build method.
Registering a page
Pages to be used by the application need to be created first, then assigned to the framework by the JBStrap
addPage() method to the Startup class (read more on this in the Application Startup chapter).
In the above code snippet we used the following parameters to create a page:
- pageId: During navigation, this page ID can be used to reference the pages. These pageIds are our navigation endpoints.
- ExampleUI: When creating pages, the UI where the page will be displayed must be specified. It is possible to display the page on multiple UIs. If a page is to be displayed on multiple UIs, then the page must have multiple, unique page IDs.
- ExamplePage: The class that contains the page to be opened.
Creating a page with parameters
Additionally, pages can have specific parameters that will be used as their default parameters. Parameters can also be specified upon opening the pages. These parameters will be passed to the page’s constructor.
To navigate to an external URL, you only need to insert a link. Use the Link component to do this.
