PowerShell Blazor Portal

Execute PowerShell scripts via .Net Blazor Server WebApp with real-time output

Useful for automation and user accessibility, this is a working .NET Blazor Server WebApp that asynchronously executes PowerShell scripts, and writes the Output, Information, Progress, Warning, and Error streams in real-time.

test.ps1 (included in this project):

for ($i=1; $i -le 5; $i++) {
    Write-Progress "Loop $i - progress output (Write-Progress)"
    Write-Information "Here's some information (Write-Information)"
    Write-Output "Normal output text (Write-Output)"
    Write-Warning "Here's some warning text (Write-Warning)"
    Write-Error "Oh no, here's some error text (Write-Error)"
    Start-Sleep -s 1
}

Looks like this...

Prerequisites

PowerShell scripts must be non-interactive; there's no means to provide input back to PowerShell scripts once they're running.
Output must be written using Write-Output, Write-Information, Write-Progress, Write-Warning, or Write-Error only. Output written with Write-Host cannot be captured and hence won't display in the results window.
Ensure the PowerShell Execution Policy has been sufficiently opened to allow your scripts to run. If in doubt and at own risk, as Administrator run:

    Set-ExecutionPolicy Unrestricted -Scope CurrentUser
    Set-ExecutionPolicy Unrestricted -Scope Process

Note: for Visual Studio users, execute the above in Package Manager Console

Place your PowerShell scripts in ~/Scripts/. .NET requires the path to be relative to the project, hence this location.
