Following this discussion on the node.js mailing list about managing module dependencies, I thought it's worth sharing some pointers on that here.
Using NPM to bundle your module dependencies
If you're building an application that is dependent on a number of NPM modules, you can specify them in your
package.json file this way:
"jade": ">= 0.0.1",
By doing so, every time you checkout your project fresh, all you need to do to get your dependencies sorted out is:
$ npm install
Note that you can either require a specific version of a module, or a minimum version by prefixing the version number with
Managing development dependencies
If you have development related dependencies (e.g. testing framework) which you do not wish to install in production, specify them using the
Managing private NPM modules
If you're working on a private module, you can also add
"private": true to the
package.json file to prevent yourself from accidentally publishing your module to the NPM registry.
Specifying a git repo as a dependency
Finally, if you want to host your module in a private git repository, but still want to bundle it as a dependency to a project, you can do that too:
The last part of the URL (
v2.3) specifies which tag should be used. You can also specify a commit hash or a branch name.
This feature was added to the NPM only around mid August, so you will need a recent version of NPM for this to work. There are a lot more such nifty feature requests in the pipeline, so keep a watch out for them on NPM's Github repo.
