New Features in npm

Posted by Robert Kowalski on .

npm is moving fast, so here are some features you might have missed since 1.3.7.

Remove devDependencies

We've noticed people running into situations where ./node_modules gathers cruft. For example, installing devDependencies during deployment due to various reasons.

To clean up in npm 1.3.10 and above, just run: npm prune --production

Repository Shorthands

Use the shorthand "username/repo" for the field repository in your package.json.

People generally use a full Git URL in the repository field:

  "repository": {
    "type": "git",
    "url": "git@github.com:robertkowalski/npm-registry-mock.git"
  },

However, GitHub is the default, so you don't need to write the full URL. This just got merged and is available in npm 1.3.10. Here's an example:

  "repository": {
    "type": "git",
    "url": "robertkowalski/npm-registry-mock"
  },

Open Repositories Directly in a Browser

Since npm 1.3.8 the new command npm repo will open the repository website in your browser for the specified package. For example, npm repo express will open the Express GitHub page.

Conclusion

In npm 1.3.7 and up a huge amount of functionality has been added -- which is why you should always keep Node up to date! I hope you learned something new about npm. You can find me on Twitter @robinson_k and GitHub at robertkowalski.
