profile.ps1

# Azure Functions profile.ps1
#
# This profile.ps1 will get executed every "cold start" of your Function App.
# "cold start" occurs when:
#
# * A Function App starts up for the very first time
# * A Function App starts up after being de-allocated due to inactivity
#
# You can define helper functions, run commands, or specify environment variables
# NOTE: any variables defined that are not environment variables will get reset after the first execution

# PowerShell Module Loading Strategy:
# This function uses a hybrid approach for loading PowerShell modules:
#   1. Primary: Azure Functions managed dependencies (requirements.psd1)
#   2. Fallback: Runtime loading from Azure Storage (shared/Load-Modules.ps1)  
#   3. Backup: PowerShell Gallery installation
# 
# For setup instructions, see: DEPLOYMENT.md (Step 2: PowerShell Module Setup)

# Initialize runtime modules from Azure Storage as fallback
. "$PSScriptRoot\shared\Load-Modules.ps1"

# Check if the primary modules are available, if not, initialize our custom loading
$criticalModules = @("Az.Accounts", "Az.KeyVault")
$needsCustomLoading = $false
foreach ($module in $criticalModules) {
    if (-not (Get-Module -Name $module -ListAvailable)) {
        $needsCustomLoading = $true
        break
    }
}

if ($needsCustomLoading) {
    Write-Host "Primary modules not available through requirements.psd1, initializing custom loading..."
    Initialize-RuntimeModules -StorageAccountName $env:STORAGE_ACCOUNT_NAME -ContainerName "modules"
} else {
    Write-Host "Modules available through requirements.psd1, skipping custom loading"
}
