An app can consist of one or more pages. A page can have a particular name and URL. You can define a URL that accepts one or more variables in the URL to define a dynamic page.
Creating a new page
Within the app editor, click the Create App Page button.
Once the page has been created, it will be listed in the pages tab.
To update the content of a page, click the Edit Code button.
As an example, you could add a button to your page.
Copy New-UDButton -Text 'What page is this?' -OnClick {
Show-UDToast $UDPage
} Once you have added the controls you would like to the page, you can add it to your app. To reference the page in your app, use Get-UDPage.
Copy New-UDApp -Pages @(
Get-UDPage -Name 'Users'
) Basic Page
A basic page can be defined using the New-UDPage cmdlet. You could navigate to this page by visiting the /appURL of your dashboard.
Copy $Pages = @()
$Pages += New-UDPage -Name 'Dashboard' -Content {
New-UDTypography -Text 'Dashboard'
}
New-UDApp -Title 'Pages' -Pages $Pages App with Multiple Pages
Apps can have multiple pages, and those pages can be defined by passing an array of UDPages to New-UDApp
Copy $Pages = @()
$Pages += New-UDPage -Name 'App One' -Content {
New-UDTypography -Text 'App Two'
}
$Pages += New-UDPage -Name 'App Two' -Content {
New-UDTypography -Text 'App Two'
}
New-UDApp -Title 'Pages' -Pages $Pages You may want to organize your app into multiple PS1 files. You can do this using pages.
Copy $UDScriptRoot = $PSScriptRoot
$Pages = @()
$Pages += New-UDPage -Name 'App One' -Content {
. "$UDScriptRoot\db1.ps1"
}
$Pages += New-UDPage -Name 'App Two' -Content {
. "$UDScriptRoot\db2.ps1"
}
New-UDApp -Title 'Pages' -Pages $Pages Page with a Custom URL
A page can have a custom URL by using the -Url parameter. You could navigate to this page by visiting the /db URL of your app.
Copy $Pages = @()
$Pages += New-UDPage -Name 'App' -Url '/db' -Content {
New-UDTypography -Text 'App'
}
New-UDApp -Title 'Pages' -Pages $Pages Page with Variables in URL
You can define a page with variables in the URL to create pages that adapt based on that URL.
Copy $Pages = @()
$Pages += New-UDPage -Name 'Dashboard' -Url '/db/:user' -Content {
New-UDTypography -Text 'Dashboard for user: $User'
}
New-UDApp -Title 'Pages' -Pages $Pages Query string parameters
Query string parameters are passed to pages and other endpoints as a hashtable variable called $Query.
For example, if you visited a page with the following query string parameter: http://localhost:5000/dashboard/Page1?test=123
You would have access to this value using the following syntax:
Copy $Query.test
$Query['test'] Role-Based Access
Copy $Pages = @()
$Pages += New-UDPage -Name 'Administrators' -Content {
New-UDTypography -Text 'Dashboard for user: $User'
} -Role 'Administrator'
$Pages += New-UDPage -Name 'Operators' -Content {
New-UDTypography -Text 'Dashboard for user: $User'
} -Role 'Operator'
New-UDApp -Title 'Pages' -Pages $Pages The following options are available for customizing the header.
Position
Use the -HeaderPosition parameter to adjust the behavior of the header.
absolute\fixed - Remains at the top of the page, even when scrolling
relative - Remains at the top of the page. Not visible when scrolling.
Copy New-UDPage -HeaderPosition fixed -Content {
New-UDElement -tag div -Attributes @{
style = @{
height = '150vh'
}
}
} Colors
You can adjust the colors of the header by specifying the -HeaderColor and -HeaderBackgroundColor parameters. These colors will override the theme colors.
Copy New-UDPage -Name 'Home' -Content {
} -HeaderColor 'black' -HeaderBackgroundColor 'white' Navigation
Custom Navigation
Custom navigation can be defined with a list. List items can include children to create drop down sections in the navigation.
Copy $Navigation = @(
New-UDListItem -Label "Home"
New-UDListItem -Label "Getting Started" -Children {
New-UDListItem -Label "Installation" -Href '/Installation'
New-UDListItem -Label "Usage" -Href '/Usage'
New-UDListItem -Label "FAQs" -Href '/faqs'
New-UDListItem -Label "System Requirements" -Href'/requirements'
New-UDListItem -Label "Purchasing" -Href '/purchasing'
}
)
$Pages = @()
$Pages += New-UDPage -Name 'Installation' -Content {
New-UDTypography -Text "Installation"
}
$Pages += New-UDPage -Name 'Usage' -Content {
New-UDTypography -Text "Usage"
}
New-UDApp -Title "Hello, World!" -Pages $Pages -NavigationLayout permanent -Navigation $Navigation Dynamic Navigation
Dynamic navigation can be used to execute scripts during page load to determine which navigation components to show based on variables like the user, IP address or roles.
You can generate dynamic navigation by using the -LoadNavigation parameter. The value of the parameter should be a script block to execute when loading the navigation.
Copy $Navigation = {
New-UDListItem -Label "Home - $(Get-Date)"
New-UDListItem -Label "Getting Started" -Children {
New-UDListItem -Label "Installation" -Href '/installation'
New-UDListItem -Label "Usage" -Href '/usage'
New-UDListItem -Label "FAQs" -Href '/faqs'
New-UDListItem -Label "System Requirements" -Href'/requirements'
New-UDListItem -Label "Purchasing" -Href '/purchasing'
}
}
$Pages = @()
$Pages += New-UDPage -Name 'Test' -Content {
New-UDTypography -Text "Hello"
} -NavigationLayout permanent -LoadNavigation $Navigation
$Pages += New-UDPage -Name 'Test2' -Content {
New-UDTypography -Text "Hello"
} -NavigationLayout permanent -LoadNavigation $Navigation
New-UDApp -Title "Hello, World!" -Pages $Pages Role-Based Access
You can use dynamic navigation to create a navigation menu that takes advantage of roles. Use Protect-UDSection to limit who has access to particular menu items. Ensure that you also include the same role on the page.
Copy $Navigation = {
New-UDListItem -Label "Home" -Href '/Home'
Protect-UDSection -Role "Administrator" -Content {
New-UDListItem -Label "Admins" -Href '/Admins'
}
}
$Pages = @()
$Pages += New-UDPage -Name 'Home' -Content {
New-UDTypography -Text "Hello"
} -NavigationLayout permanent -LoadNavigation $Navigation
$Pages += New-UDPage -Name 'Admins' -Content {
New-UDTypography -Text "Hello"
} -NavigationLayout permanent -LoadNavigation $Navigation -Roles "Administrator"
New-UDApp -Title "Hello, World!" -Pages $Pages Layouts
The permanent layout creates a static navigation drawer on the left hand side of the page. It cannot be hidden by the user.
Copy $Pages = @()
$Pages += New-UDPage -Name 'Test' -Content {
New-UDTypography -Text "Hello"
} -NavigationLayout permanent
$Pages += New-UDPage -Name 'Test2' -Content {
New-UDTypography -Text "Hello"
} -NavigationLayout permanent
New-UDApp -Title "Hello, World!" -Pages $Pages The temporary layout creates a navigation drawer that can be opened using a hamburger menu found in the top left corner. This is the default setting.
Copy $Pages = @()
$Pages += New-UDPage -Name 'Test' -Content {
New-UDTypography -Text "Hello"
} -NavigationLayout temporary
$Pages += New-UDPage -Name 'Test2' -Content {
New-UDTypography -Text "Hello"
} -NavigationLayout temporary
New-UDApp -Title "Hello, World!" -Pages $Pages Horizontal Navigation
You can use New-UDAppBar with a blank page to create horizontal navigation.
Copy New-UDApp -Title 'PowerShell Universal' -Pages @(
New-UDPage -Name 'Page' -Content {
New-UDAppBar -Children {
New-UDTypography -Text "Title" -Variant h4 -Style @{
marginRight = "50px"
}
New-UDMenu -Variant text -Text "Settings" -Children {
New-UDMenuItem -Text 'Item 1' -OnClick { Invoke-UDRedirect "/item1" }
New-UDMenuItem -Text 'Item 2' -OnClick { Invoke-UDRedirect "/item1" }
New-UDMenuItem -Text 'Item 3' -OnClick { Invoke-UDRedirect "/item1" }
}
New-UDMenu -Variant text -Text "Options" -Children {
New-UDMenuItem -Text 'Item 1' -OnClick { Invoke-UDRedirect "/item1" }
New-UDMenuItem -Text 'Item 2' -OnClick { Invoke-UDRedirect "/item1" }
New-UDMenuItem -Text 'Item 3' -OnClick { Invoke-UDRedirect "/item1" }
}
New-UDMenu -Variant text -Text "Tools" -Children {
New-UDMenuItem -Text 'Item 1' -OnClick { Invoke-UDRedirect "/item1" }
New-UDMenuItem -Text 'Item 2' -OnClick { Invoke-UDRedirect "/item1" }
New-UDMenuItem -Text 'Item 3' -OnClick { Invoke-UDRedirect "/item1" }
}
} -DisableThemeToggle
} -Blank
) Logo
You can display a logo in the navigation bar by using the -Logo parameter.
Now, when creating your page, you can specify the path to the logo.
Copy New-UDPage -Name 'Home' -Logo '/assets/favicon.png' -Content {
} The logo will display in the top left corner.
You can define custom content to include in the header by using the -HeaderContent parameter.
Copy $Page = New-UDPage -Name 'Home' -Content {
} -HeaderContent {
New-UDButton -Icon (New-UDIcon -Icon Users) -Text 'User'
}
New-UDApp -Title "Dashboard" -Pages $Page Dynamic Page Title
Page titles are static by default, but you can override this behavior by using -LoadTitle. It will be called when the page is loaded. This is useful when defining pages in multilingual dashboards.
Copy New-UDPage -Name "Home" -LoadTitle { "Current Time" + (Get-Date) } -Content { } Static Pages
Static pages allow for better performance by not executing PowerShell to load the content of the page. This can be useful when displaying data that does not require dynamic PowerShell execution. The page content is constructed when the dashboard is started.
Copy New-UDPage -Name 'Static Page' -Content {
New-UDTypography (Get-Date)
} -Static Static pages do not have access to user specific data. This includes variables such as:
You can still include dynamic regions within pages. These dynamic regions will have access to user data. Reloading the below example will update the date and time listed in the page.
Copy New-UDPage -Name 'Static Page' -Content {
New-UDDynamic -Content {
New-UDTypography (Get-Date)
}
} -Static API
