npm(1) -- node package manager
npm <command> [args]
It is extremely configurable to support a wide variety of use cases. Most commonly, it is used to publish, discover, install, and develop node programs.
npm help to get a list of available commands.
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.
npm ls installed to show everything you've installed.
npm help ls will tell you more.
If you're using npm to develop and publish your code, check out the following help topics:
Make a package.json file. See
npm help json.
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 linkto do this.
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
- adduser: Create an account or log in. Creditials are stored (encrypted) in the user config file.
npm publishcommand to upload your code to the registry.
npm is extremely configurable. It reads its configuration options from 5 places.
- Command line switches:
Set a config with
--key val. All keys take a value, even if they are booleans (the config parser doesn't know what the options are at the time of parsing.) If no value is provided, then the option is set to boolean
- Environment Variables:
Set any config by prefixing the name in an environment variable with
npm_config_. For example,
- User Configs:
The file at $HOME/.npmrc is an ini-formatted list of configs. If present, it is parsed. If the
userconfigoption is set in the cli or env, then that will be used instead.
- Global Configs:
The file found at ../etc/npmrc (from the node executable, by default this resolves to /usr/local/etc/npmrc) will be parsed if it is found. If the
globalconfigoption is set in the cli, env, or user config, then that file is parsed instead.
npm's default configuration options are defined in lib/utils/default-config.js. These should not be changed.
npm help config for much much more information.
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
package.json file. You can view them
easily by doing
npm view npm contributors.
If you would like to contribute, but don't know what to work on, check the issues list or ask on the mailing list.
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. He will no doubt tell you to put the output in a gist or email.
