npm(1) -- node package manager
npm <command> [args]
npm help to get a list of commands.
STATUS: Useful Beta
The core functionality is there. It works.
Please use this software. It will cut you occasionally. Let me know when you find a rough edge, and I'll sand it down for you.
I appreciate your sense of adventure.
You probably got npm because you want to install stuff.
npm install blerg to install the latest version of "blerg". Check out
npm help install for more info. It can do a lot of stuff.
npm ls command to show everything that's available. Looking for
npm ls express. Looking for the latest express?
npm ls express latest. (The arguments are just simple greps.) And of course,
npm help ls will tell you more.
npm ls installed to show everything you've installed.
npm config command to manage how npm does stuff and where it puts things.
It stores your configs in the
~/.npmrc file. Check
npm help config for more
info on that, if you care.
You can override any config for just a single command by doing
on the command line.
If you're using npm to develop and publish your code, check out the following topics:
- json: Make a package.json file. The "json" help doc will tell you what to put in it.
- link: For linking your current working code into Node's path, so that you don't have to reinstall every time you make a change. Use "npm link" to do this.
- install: It's a good idea to install things if you don't need the symbolic link. Especially, installing other peoples code from the registry is done via "npm install".
npm addusercommand to add a user account for the npm registry, or to authorize yourself on a new machine. If you forget your password, send an email to email@example.com and we'll delete your account so you can recreate it.
npm publishcommand to upload your code to the registry, so that other people can install it easily.
npm help coding-styleif you plan to submit code. You don't have to agree with it, but you do have to follow it.
- docs: If you find an error in the documentation, edit the appropriate markdown file in the "doc" folder. (Don't worry about generating the man page.)
Contributors are listed in npm's
Put the files where they need to be so that node can find them using the methods it already uses.
Be lazy, not clever.
The file system is the database.
Sync with habits that are already in use.
Packages should be maintained by their authors, not by the package manager author.
Steer clear of dependency hell.
Plenty. Luckily, npm is actively maintained as of this writing.
When you find issues, please report them:
Be sure to include all of the output from the npm command that didn't work as expected.
You can also look for isaacs in #node.js on irc://irc.freenode.net.
