Tasks/Invoke-WhiskeyNodeLicenseChecker.ps1
function Invoke-WhiskeyNodeLicenseChecker { <# .SYNOPSIS Generates a report of each dependency's license. .DESCRIPTION The `NodeLicenseChecker` task runs the node module `license-checker` against all the modules listed in the `dependencies` and `devDepenendencies` properties of the `package.json` file for this application. The task will create a JSON report file named `node-license-checker-report.json` located in the `.output` directory of the build root. This task installs the latest LTS version of Node into a `.node` directory (in the same directory as your whiskey.yml file). To use a specific version, set the `engines.node` property in your package.json file to the version you want. (See https://docs.npmjs.com/files/package.json#engines for more information.) If the application's `package.json` file does not exist in the build root next to the `whiskey.yml` file, specify a `WorkingDirectory` where it can be found. # Properties * `Version`: the version of the license checker to use. The default is the latest version. * `NodeVersion`: the version of Node to use. By default, the version in the `engines.node` property of your package.json file is used. If that is missing, the latest LTS version of Node is used. # Examples ## Example 1 BuildTasks: - NodeLicenseChecker This example will run `license-checker` against the modules listed in the `package.json` file located in the build root. ## Example 2 BuildTasks: - NodeLicenseChecker: Version: 13.0.1 This example will install and use version 13.0.1 of the license checker. #> [CmdletBinding()] [Whiskey.Task('NodeLicenseChecker')] [Whiskey.RequiresTool('Node', 'NodePath',VersionParameterName='NodeVersion')] [Whiskey.RequiresTool('NodeModule::license-checker', 'LicenseCheckerPath', VersionParameterName='Version')] param( [Parameter(Mandatory=$true)] [Whiskey.Context] $TaskContext, [Parameter(Mandatory=$true)] [hashtable] $TaskParameter ) Set-StrictMode -Version 'Latest' Use-CallerPreference -Cmdlet $PSCmdlet -SessionState $ExecutionContext.SessionState $licenseCheckerPath = Assert-WhiskeyNodeModulePath -Path $TaskParameter['LicenseCheckerPath'] -CommandPath 'bin\license-checker' -ErrorAction Stop $nodePath = Assert-WhiskeyNodePath -Path $TaskParameter['NodePath'] -ErrorAction Stop Write-WhiskeyTiming -Message ('Generating license report') $reportJson = Invoke-Command -NoNewScope -ScriptBlock { & $nodePath $licenseCheckerPath '--json' } Write-WhiskeyTiming -Message ('COMPLETE') $report = Invoke-Command -NoNewScope -ScriptBlock { ($reportJson -join [Environment]::NewLine) | ConvertFrom-Json } if (-not $report) { Stop-WhiskeyTask -TaskContext $TaskContext -Message 'License Checker failed to output a valid JSON report.' } Write-WhiskeyTiming -Message 'Converting license report.' # The default license checker report has a crazy format.
