Understanding npm

A regularly updating survey of the npm community.

Designed with love by NodeSource for our Node.js family.


The project itself makes extensive use of npm. Once installed, there's a total of 406 unique packages in the dependency tree. Most notably:

Running the Site Locally

Getting Started

Before you can run the site on your machine, you'll need to ensure that you have the latest version of Node installed (especially important is

[email protected]
, which we use for scoped module support).

When you're ready, clone the repository from GitHub and install the visualisation's dependencies from npm:

git clone [email protected]:nodesource/understanding-npm.git
cd understanding-npm
npm install

Now, you should be ready to start the server up like so:

npm start

Updating the Registry Data

This is all done from the

package, and requires you to download >1GB of metadata from the npm registry, npm downloads API and GitHub API. Depending on your location and connectivity, this could take anywhere from a day to a week (requests have to be throttled to avoid hitting any rate limits).

A sample dataset has been prepared and included in the repository for everybody's convenience, so you most likely won't have to deal with this directly. If, however, you'd still like to update the data locally you should check out the documentation in


Local Subpackages

The site is split out into smaller local packages that are installed with npm. When developing, we use

to make this process easier.

Each package should have its own independent
documenting its purpose and usage. Some notes on the packages included in this project:
  • @unpm
    -scoped packages are part of the final project.
  • @nsight
    -scoped packages are part of the final project, but likely to be reused in future N|Sight projects.
  • @x
    -scoped packages are experiments, which are interesting for process documentation but not otherwise used in the final product.
  • gooey
    is the only package unscoped package remaining (pending some reorganisation, and sorting out a new name).

Some other packages that were born from this project include:
