CPM (CommonJS Package Manager) is designed for simple, straightforward installation of CommonJS packages into a target location/package. This is specifically designed to make it easy to install packages for use in the browser or any server side JS environment (like Node). CPM is based on the CommonJS Mappings specification, and will install all dependencies listed in the dependencies or mappings hash.


Download and unzip/untar CPM. Then edit the startup script (cpm for unix or cpm.bat for windows) to point to the path where you have put CPM, and copy the script into a directory in your path (like /usr/local/bin in unix or C:\windows in windows). You can also modify the registry URL in the startup script as well. The startup script also includes directions (in the comments) for running from Node instead of Rhino.

A quick one-line install on Mac OS and Linux is:

curl -L | sh

To install to a different location, you can use CPM_INSTALL_LIB for the directory where to put cpm's directory and CPM_INSTALL_BIN for the directory to symlink the cpm script:

curl -L | CPM_INSTALL_LIB=~/lib CPM_INSTALL_BIN=~/bin sh

This would install cpm's libraries in "/lib/cpm" and symlink the cpm script to "/bin/cpm". Make sure that your ~/lib directory exists before doing this.

If you are running on Mac OS, then you will probably need to edit the cpm script (the one that "which cpm" points to) and manually set CPM_PATH to your CPM folder that holds the jars and lib directory.


The main use of CPM is to install packages. To install a package, go to the directory where your JavaScript is stored and where you want your packages to be installed and run:

cpm install package-to-install

The packages will be downloaded and unzipped into the current working directory. CPM will also create any top level package modules to point to package "main" modules. You should be able to load the modules with any AMD compliant module loader, including RequireJS, Dojo, or Curl. For example:

<script src="dojo/dojo .js" data-dojo-config="async: true"></script>

You can also indicate the desired version to install with a second parameter:

cpm install package-to-install 1.2.2

To upgrade a package to the latest version, you can run:

cpm upgrade package-to-upgrade

To specify a directory to install packages to, you can run:

cpm --packages-path=~/Projects/my_project/libs install package-to-install

To specify a different registry to install packages from, you can run:

cpm --registry= install package-to-install
