Support for changing Server Root Path, both Literal and Relative

[Badgerati]

When Pode starts the server's root path is set the $MyInvocation.PSScriptRoot path, which defines the base path to the /views, /public and /errors directories.

Normally this is perfectly fine, but there are times when you need to alter the root path to your server because those directories above are located in a further subdirectory - or parent directory. Such a case could be when hosting your Pode server as a module, and the root path is set from the invocation of your module and not the Pode server.

• Should be configurable using the pode.json file - as server.root
• Support both literal and relative paths (testing if new path exists)
  • If relative, the path should be joined onto the invocation path (Join-Path)
  • If literal, use the supplied path instead of the invocation path
  • If none, just use the already default of the invocation path

How about /routes to auto include .ps1 files.

I do it like this:

$RootPath   = $PSScriptRoot
$RouteFiles = @()
$RoutePath  = (Join-Path -Path $RootPath -ChildPath "Routes")
if (Test-Path $RoutePath) {
    Get-ChildItem -Path $RoutePath -Recurse -Filter *.ps1 | ForEach-Object {
        $RouteFiles += $_.FullName
        Write-Host $_.FullName
    }
}
Server -Threads 2 {
    listen *:8085 http
    engine pode
    
    $RouteFiles | ForEach-Object {
        . $_
    }
}

That's a pretty neat idea for another feature - though it could be dangerous for people that already have a /routes directory, like yourself 😛

For this change, it's purely to help fix issues where the views/public/errors directories can't be found by Pode because the invocation path gets a little screwy - happens when starting the server within another function within another module, and the /views are one level deeper than the invocation path.

This worked for me! The only strange thing is that the json file has to be in the same path as the script/module calling it. So my json file for pode is in my "public" function directory. Thanks for adding this!

Ah, of course! I can add a -RootPath parameter to the server function then, same logic as the config just in code 😃
