Powershell script to parse a package.json version and use as the build number in TeamCity

package-json-build-number.ps1

$version = (Get-Content package.json) -join "`n" | ConvertFrom-Json | Select -ExpandProperty "version"
$buildCounter = "%build.counter%"
$buildNumber = "$version.$buildCounter"
Write-Host "##teamcity[buildNumber '$buildNumber']"

Beautiful! Thanks for sharing this with a gist! 🥇

Very helpful, thanks!

No problem, glad it was useful!

Another way I stumbled upon:

$version = node -p "require('./package.json').version"

Oh nice use of -p @philharlow - I hadn't seen this before. For anyone reading this, here are the docs for -p - it evaluates the argument as JavaScript and returns the result.
