You are a great developer. You write tests and run your builds through a CI and only publish to npm if all of your tests pass.
But there is a problem, your CI of choice (outside of Jenkins), doesn't support publishing to npm...
Now you can!
Install this package globally on your CI and when ready to deploy, run npm-publish.
This command can take args as well as env variables.
$ npm-publish --npmuser <username> --npmemail <email> --npmpassword <password>
Environment variables are NPMUSER, NPMEMAIL, and NPMPASSWORD.
Mix and match if you like!
