function Publish-WhiskeyNodeModule { <# .SYNOPSIS Publishes a Node module package to the target NPM registry .DESCRIPTION The `Publish-WhiskeyNodeModule` function utilizes NPM's `publish` command to publish Node module packages. You are required to specify what version of Node.js you want in the engines field of your package.json file. (See https://docs.npmjs.com/files/package.json#engines for more information.) The version of Node is installed for you using NVM. This task accepts these parameters: * `WorkingDirectory`: the directory where the NPM publish command will be run. Defaults to the directory where the build's `whiskey.yml` file was found. Must be relative to the `whiskey.yml` file. .EXAMPLE Publish-WhiskeyNodeModule -TaskContext $context -TaskParameter @{} Demonstrates how to `publish` the Node module package located in the directory specified by the `$context.BuildRoot` property. The function would run `npm publish`. Publish-WhiskeyNodeModule -TaskContext $context -TaskParameter @{ WorkingDirectory = '\PathToPackage\RelativeTo\whiskey.yml' } Demonstrates how to `publish` the Node module package located in the directory specified by the `WorkingDirectory` property. The function would run `npm publish`. #> [Whiskey.Task("PublishNodeModule", SupportsInitialize=$true)] [CmdletBinding()] param( [Parameter(Mandatory=$true)] [object] # The context the task is running under. $TaskContext, [Parameter(Mandatory=$true)] [hashtable] # The parameters/configuration to use to run the task.
