function Invoke-WhiskeyNpmInstall { <# .SYNOPSIS Installs Node.js packages. .DESCRIPTION The `NpmInstall` task will use NPM's `install` command to install Node.js packages. If not given any `Package`, the task will run `npm install` to install all packages listed in the `package.json` `dependency` and `devDependency` properties. If any packages are given in the `Package` property, only those packages will be installed and not any listed in the `package.json` file. The task will fail if `npm install` returns a non-zero exit code or if the expected path to the module does not exist after calling `npm install`. The `Package` property accepts a list of packages that should be installed. You may specify just the package name or the package name with a semantic version number, e.g. `rimraf: ^2.0.0`. You must 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. You may additionally specify a version of NPM to use in the engines field of your package.json file. NPM will be downloaded into your package's 'node_modules' directory at the specified version. This local version of NPM will be used to execute all NPM tasks. # Properties # * `Package`: a list of NPM packages to install. List items can simply be package names, `rimraf`, or package names with semantic version numbers that NPM understands, e.g. `rimraf: ^2.0.0`. When using the `Package` property the task will only install the given packages and not the ones listed in the `package.json` file. # * `WorkingDirectory`: the directory where the `package.json` exists. Defaults to the directory where the build's `whiskey.yml` file was found. Must be relative to the `whiskey.yml` file. # * `NpmRegistryUri` (mandatory): the uri to set a custom npm registry. # Examples ## Example 1 BuildTasks: - NpmInstall: NpmRegistryUri: "http://registry.npmjs.org" This example will install all the Node packages listed in the `package.json` file to the `BUILD_ROOT\node_modules` directory. ## Example 2 BuildTasks: - NpmInstall: NpmRegistryUri: "http://registry.npmjs.org" Package: - gulp This example will install the Node package `gulp` to the `BUILD_ROOT\node_modules` directory. ## Example 3 BuildTasks: - NpmInstall: NpmRegistryUri: "http://registry.npmjs.org" WorkingDirectory: app Package: - gulp - rimraf: ^2.0.0 This example will install the Node packages `gulp` and the latest 2.x.x version of `rimraf` to the `BUILD_ROOT\app\node_modules` directory. #> [Whiskey.Task("NpmInstall", SupportsClean=$true, SupportsInitialize=$true)] [CmdletBinding()] param( [Parameter(Mandatory=$true)] [object] $TaskContext, [Parameter(Mandatory=$true)] [hashtable] $TaskParameter ) Set-StrictMode -Version 'Latest' Use-CallerPreference -Cmdlet $PSCmdlet -SessionState $ExecutionContext.SessionState $startedAt = Get-Date function Write-Timing { param( $Message ) $now = Get-Date Write-Debug -Message ('[{0}] [{1}] {2}' -f $now,($now - $startedAt),$Message) } $npmRegistryUri = $TaskParameter['NpmRegistryUri'] if (-not $NpmRegistryUri) { Stop-WhiskeyTask -TaskContext $TaskContext -Message 'Property ''NpmRegistryUri'' is mandatory.
