Endpoint Initialization

Endpoints within Universal Dashboard are run using a shared runspace pool. Runspaces are created and retained to ensure that performance is as best as it can be. As requests come in, more runspaces will be created up to a certain limit and then runspaces will be reused. When the runspaces are created, they are initialized with the return value of the New-UDEndpointInitialization cmdlet. This value is passed to the New-UDDashboard cmdlet via the -EndpointInitialization cmdlet.

Passing Variables to Endpoints

Much like global: scope variables, variables that you pass to endpoints are available in all endpoints. To pass a variable, simply provide the name of the variable to the initialization cmdlet.

$MyVariable = "Hi, there!"
New-UDEndpointInitialization -Variable MyVariable

You'll now be able to use $MyVariable in all your endpoints.

You can also pass arrays of variable names.

$MyVariable = "Hi, there!"
$YourVariable = "Good bye!"
New-UDEndpointInitialization -Variable @("MyVariable", "YourVariable")

Passing Functions to Endpoints

Functions are passed just like variables but using the -Function parameter.

function Get-MeABeer () { }
New-UDEndpointInitialization -Function "Get-MeABeer"

They also support arrays.

function Get-MeABeer () { }
function Get-YourSelfABeer() { }
New-UDEndpointInitialization -Function @("Get-MeABeer", "Get-YourSelfABeer")

Loading Modules in Endpoints

The name or path of the module should be provided to the -Module parameter. You can specify arrays of modules or paths. Relative paths are relative to the current file.

New-UDEndpointInitialization -Module @("ActiveDirectory", ".\HelpFunctions.psm1")

Other Endpoint Initialization Properties

The New-UDEndpointInitiailization cmdlet returns a InitialSessionState object. This object is part of the PowerShell SDK and provides more customization than does the cmdlet. You can store the result in a variable and set additional properties.

$Init = New-UDEndpointInitialization 
$Init.LanguageMode = 'ConstrainedLanguage'
