< h2 id = "DESCRIPTION" > DESCRIPTION< / h2 >
< p > npm is the package manager for the Node JavaScript platform. It puts
modules in place so that node can find them, and manages dependency
conflicts intelligently.< / p >
< p > 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.< / p >
< p > Run < code > npm help< / code > to get a list of available commands.< / p >
< h2 id = "INTRODUCTION" > INTRODUCTION< / h2 >
< p > You probably got npm because you want to install stuff.< / p >
< p > Use < code > npm install blerg< / code > to install the latest version of " blerg" . Check out
< code > < a href = "../cli/npm-install.html" > npm-install(1)< / a > < / code > for more info. It can do a lot of stuff.< / p >
< p > Use the < code > npm search< / code > command to show everything that' s available.
Use < code > npm ls< / code > to show everything you' ve installed.< / p >
< h2 id = "DIRECTORIES" > DIRECTORIES< / h2 >
< p > See < code > < a href = "../files/npm-folders.html" > npm-folders(5)< / a > < / code > to learn about where npm puts stuff.< / p >
< p > In particular, npm has two modes of operation:< / p >
< ul > < li > global mode:< br / > npm installs packages into the install prefix at
< code > prefix/lib/node_modules< / code > and bins are installed in < code > prefix/bin< / code > .< / li > < li > local mode:< br / > npm installs packages into the current project directory, which
defaults to the current working directory. Packages are installed to
< code > ./node_modules< / code > , and bins are installed to < code > ./node_modules/.bin< / code > .< / li > < / ul >
< p > Local mode is the default. Use < code > --global< / code > or < code > -g< / code > on any command to
operate in global mode instead.< / p >
< h2 id = "DEVELOPER-USAGE" > DEVELOPER USAGE< / h2 >
< p > If you' re using npm to develop and publish your code, check out the
following help topics:< / p >
< ul > < li > json:
Make a package.json file. See < code > < a href = "../files/package.json.html" > package.json(5)< / a > < / code > .< / li > < li > 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
< code > npm link< / code > to do this.< / li > < li > 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
< code > npm install< / code > < / li > < li > adduser:
Create an account or log in. Credentials are stored in the
user config file.< / li > < li > publish:
Use the < code > npm publish< / code > command to upload your code to the registry.< / li > < / ul >
< h2 id = "CONFIGURATION" > CONFIGURATION< / h2 >
< p > npm is extremely configurable. It reads its configuration options from
5 places.< / p >
< ul > < li > Command line switches:< br / > Set a config with < code > --key val< / code > . 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 < code > true< / code > .< / li > < li > Environment Variables:< br / > Set any config by prefixing the name in an environment variable with
< code > npm_config_< / code > . For example, < code > export npm_config_key=val< / code > .< / li > < li > User Configs:< br / > The file at $HOME/.npmrc is an ini-formatted list of configs. If
present, it is parsed. If the < code > userconfig< / code > option is set in the cli
or env, then that will be used instead.< / li > < li > Global Configs:< br / > 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 < code > globalconfig< / code > option is set in the cli, env, or user config,
then that file is parsed instead.< / li > < li > Defaults:< br / > npm' s default configuration options are defined in
lib/utils/config-defs.js. These must not be changed.< / li > < / ul >

You don' t have to agree with it, but you do have to follow it.< / li > < li > 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.)< / li > < / ul >
