puppet-nodejs

This module allows you to install Node.js and NPM. This module is published on the Puppet Forge as willdurand/nodejs.

Version 1.9

The 1.x branch will be EOLed two months after 2.0 is released. If you need the docs for 1.x, see 1.9.

Installation

Manual installation

This modules depends on puppetlabs/stdlib. So all repositories have to be checked out:

git clone git://github.com/willdurand/puppet-nodejs.git modules/nodejs
git clone git://github.com/puppetlabs/puppetlabs-stdlib.git modules/stdlib

For Redhat based OS, the following are (typical) additional requirements:

git clone git://github.com/treydock/puppet-gpg_key.git modules/gpg_key

Puppet Module Tool:

puppet module install willdurand/nodejs

Librarian-puppet:

mod 'willdurand/nodejs', '1.x.x'

Usage

There are a few ways to use this puppet module. The easiest one is just using the class definition:

class { 'nodejs':
  version => 'v6.0.0',
}

This will compile and install Node.js version v6.0.0 to your machine. node and npm will be available in your $PATH via /usr/local/node/node-default/bin so you can just start using node.

Shortcuts are provided to easily install the latest or stable release by setting the version parameter to latest or stable. It will automatically look for the last release available on https://nodejs.org.

class { 'nodejs':
  version => 'stable',
}

Setup using the pre-built installer

To use the pre-built installer version provided via https://nodejs.org/download you have to set make_install to false

class { 'nodejs':
  version      => 'stable',
  make_install => false,
}

Setup with a given download timeout

Due to infrastructures with slower connections the download of the nodejs binaries should be configurable:

::Nodejs::Install::Download {
  timeout => 300
}

class { '::nodejs':
  make_install => false,
}

Setup multiple versions of Node.js

If you need more than one installed version of Node.js on your machine, you can just do it using the nodejs::install puppet define.

nodejs::install { 'v6.0.0':
  version => 'v6.0.0',
}
nodejs::install { 'v5.0.0':
  version => 'v5.0.0',
}

This snippet will install version v6.0.0 and v5.0.0 on your machine. Keep in mind that a Node.js version installed via nodejs::install will provide only versioned binaries inside /usr/local/bin!

/usr/local/bin/node-v6.0.0
/usr/local/bin/npm-v6.0.0

/usr/local/bin/node-v5.0.0
/usr/local/bin/npm-v5.0.0

By default, this module creates a symlink for the node binary (and npm) with Node.js version appended into /usr/local/bin e.g. /usr/local/bin/node-v5.0.0. All parameters available in the class definition are also available for nodejs::install.

It is also possible to remove those versions again:

::nodejs::install { 'node-v5.4':
  ensure  => absent,
  version => 'v5.4.1',
}

After the run the directory /usr/local/node/node-v5.4.1 has been purged. The link /usr/local/bin/node-v5.4.1 is also purged.

Note: It is not possible to install and uninstall an instance in the same run.

When attempting to remove the default instance this can be only done when having the ::nodejs class NOT defined as otherwise duplicate resource errors would occur. After that no new default instance will be configured.

Setup using custom amount of cpu cores

By default, all available cpu cores are being used to compile nodejs. Set cpu_cores to any number of cores you want to use.

class { 'nodejs':
  version   => 'stable',
  cpu_cores => 2,
}

Configuring $NODE_PATH

The environment variable $NODE_PATH can be configured using the init manifest:

class { '::nodejs':
  version   => 'latest',
  node_path => '/your/custom/node/path',
}

It is not possible to adjust a $NODE_PATH through ::nodejs::install.

Binary path

node and npm are linked to /usr/local/bin to be available in your system $PATH by default. To link those binaries to e.g /bin, just set the parameter target_dir.

class { 'nodejs':
  version    => 'stable',
  target_dir => '/bin',
}

NPM

Also, this module installs NPM by default.

NPM Provider

This module adds a new provider: npm. You can use it as usual:

package { 'express':
  provider => npm
}

Note: When deploying a new machine without nodejs already installed, your npm package definition requires the nodejs class:

class { 'nodejs':
  version => 'stable'
}

package { 'express':
  provider => 'npm',
  require  => Class['nodejs']
}

NPM installer

The nodejs installer can be used if a npm package should not be installed globally, but in a certain directory.

There are two approaches how to use this feature:

Installing a single package into a directory

::nodejs::npm { 'npm-webpack':
  ensure       => present, # absent would uninstall this package
  pkg_name     => 'webpack',
  version      => 'x.x', # optional
  install_opt  => '-x -y -z', # options passed to the "npm install" cmd, optional
  remove_opt   => '-x -y -z', # options passed to the "npm remove" cmd (in case of ensure => absent), optional
  exec_as_user => 'vagrant',  # exec user, optional
  directory    => '/target/directory', # target directory
}

This would install the package webpack into /target/directory with version x.x.

Executing a package.json file

::nodejs::npm { 'npm-install-dir':
  list         => true, # flag to tell puppet to execute the package.json file
  directory    => '/target',
  exec_as_user => 'vagrant',
  install_opt  => '-x -y -z',
}

Proxy

When your puppet agent is behind a web proxy, export the http_proxy environment variable:

export http_proxy=http://myHttpProxy:8888

Running the tests

Install the dependencies using Bundler:

bundle install

Run the following command:

bundle exec rake test
