puppet-nodejs

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

Installation

Manual installation

This modules depends on puppetlabs/stdlib and maestrodev/puppet-wget. 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
git clone git://github.com/maestrodev/puppet-wget.git modules/wget

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 => 'v0.10.25',
}

This will compile and install Node.js version v0.10.25 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 http://nodejs.org.

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

Setup using the pre-built installer

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

class { 'nodejs':
  version      => 'stable',
  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 { 'v0.10.17':
  version => 'v0.10.17',
}
nodejs::install { 'v0.10.25':
  version => 'v0.10.25',
}

This snippet will install version v0.10.17 and v0.10.25 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-v0.10.17
/usr/local/bin/node-v0.10.25

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-v0.10.17. All parameters available in the class definition are also available for nodejs::install.

NPM symlinks cannot be created since every npm instance would use the default node interpreter which may cause errors. If you'd like to use another npm interpreter, please do something like this:

/usr/local/node/node-vx.x/bin/node /usr/local/node/node-vx.x/bin/npm run your_command

For 2.x it is planned to use NVM and refactor the whole nodejs installer (See #119

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.

If the instance is the default one, an error will be thrown.

Note: It is not possible to install and uninstall an instance in the same run. Note: The default instance of nodejs cannot be removed. In this case an error will be raised.

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. Since versions v0.6.3 of Node.js npm is included in every installation! For older versions, you can set parameter with_npm => false to not install npm.

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_GEMFILE=.gemfile bundle install

Run the following command:

BUNDLE_GEMFILE=.gemfile bundle exec rake test
