			npm-config(7) -- More than you probably want to know about npm configuration
			============================================================================

			## DESCRIPTION

			npm gets its configuration values from the following sources, sorted by priority:

			### Command Line Flags

			Putting `--foo bar` on the command line sets the `foo` configuration
			parameter to `"bar"`. A `--` argument tells the cli parser to stop
			reading flags. A `--flag` parameter that is at the end of the
			command will be given the value of `true`.

			### Environment Variables

			Any environment variables that start with `npm_config_` will be
			interpreted as a configuration parameter. For example, putting
			`npm_config_foo=bar` in your environment will set the `foo`
			configuration parameter to `bar`. Any environment configurations that
			are not given a value will be given the value of `true`. Config
			values are case-insensitive, so `NPM_CONFIG_FOO=bar` will work the
			same.

			### npmrc Files

			The four relevant files are:

			* per-project config file (/path/to/my/project/.npmrc)
			* per-user config file (~/.npmrc)
			* global config file ($PREFIX/etc/npmrc)
			* npm builtin config file (/path/to/npm/npmrc)

			See npmrc(5) for more details.

			### Default Configs

			Run `npm config ls -l` to see a set of configuration parameters that are
			internal to npm, and are defaults if nothing else is specified.

			## Shorthands and Other CLI Niceties

			The following shorthands are parsed on the command-line:

			* `-v`: `--version`
			* `-h`, `-?`, `--help`, `-H`: `--usage`
			* `-s`, `--silent`: `--loglevel silent`
			* `-q`, `--quiet`: `--loglevel warn`
			* `-d`: `--loglevel info`
			* `-dd`, `--verbose`: `--loglevel verbose`
			* `-ddd`: `--loglevel silly`
			* `-g`: `--global`
			* `-C`: `--prefix`
			* `-l`: `--long`
			* `-m`: `--message`
			* `-p`, `--porcelain`: `--parseable`
			* `-reg`: `--registry`
			* `-f`: `--force`
			* `-desc`: `--description`
			* `-S`: `--save`
			* `-D`: `--save-dev`
			* `-O`: `--save-optional`
			* `-B`: `--save-bundle`
			* `-E`: `--save-exact`
			* `-y`: `--yes`
			* `-n`: `--yes false`
			* `ll` and `la` commands: `ls --long`

			If the specified configuration param resolves unambiguously to a known
			configuration parameter, then it is expanded to that configuration
			parameter. For example:

			npm ls --par
			# same as:
			npm ls --parseable

			If multiple single-character shorthands are strung together, and the
			resulting combination is unambiguously not some other configuration
			param, then it is expanded to its various component pieces. For
			example:

			npm ls -gpld
			# same as:
			npm ls --global --parseable --long --loglevel info

			## Per-Package Config Settings

			When running scripts (see `npm-scripts(7)`) the package.json "config"
			keys are overwritten in the environment if there is a config param of
			`<name>[@<version>]:<key>`. For example, if the package.json has
			this:

			{ "name" : "foo"
			, "config" : { "port" : "8080" }
			, "scripts" : { "start" : "node server.js" } }

			and the server.js is this:

			http.createServer(...).listen(process.env.npm_package_config_port)

			then the user could change the behavior by doing:

			npm config set foo:port 80

			See package.json(5) for more information.

			## Config Settings

			### access

			* Default: `restricted`
			* Type: Access

			When publishing scoped packages, the access level defaults to `restricted`. If
			you want your scoped package to be publicly viewable (and installable) set
			`--access=public`. The only valid values for `access` are `public` and
			`restricted`. Unscoped packages _always_ have an access level of `public`.

			### always-auth

			* Default: false
			* Type: Boolean

			Force npm to always require authentication when accessing the registry,
			even for `GET` requests.

			### also

			* Default: null
			* Type: String

			When "dev" or "development" and running local `npm shrinkwrap`,
			`npm outdated`, or `npm update`, is an alias for `--dev`.

			### bin-links

			* Default: `true`
			* Type: Boolean

			Tells npm to create symlinks (or `.cmd` shims on Windows) for package
			executables.

			Set to false to have it not do this. This can be used to work around
			the fact that some file systems don't support symlinks, even on
			ostensibly Unix systems.

			### browser

			* Default: OS X: `"open"`, Windows: `"start"`, Others: `"xdg-open"`
			* Type: String

			The browser that is called by the `npm docs` command to open websites.

			### ca

			* Default: The npm CA certificate
			* Type: String, Array or null

			The Certificate Authority signing certificate that is trusted for SSL
			connections to the registry. Values should be in PEM format with newlines
			replaced by the string "\n". For example:

			ca="-----BEGIN CERTIFICATE-----\nXXXX\nXXXX\n-----END CERTIFICATE-----"

			Set to `null` to only allow "known" registrars, or to a specific CA cert
			to trust only that specific signing authority.

			Multiple CAs can be trusted by specifying an array of certificates:

			ca[]="..."
			ca[]="..."

			See also the `strict-ssl` config.

			### cafile

			* Default: `null`
			* Type: path

			A path to a file containing one or multiple Certificate Authority signing
			certificates. Similar to the `ca` setting, but allows for multiple CA's, as
			well as for the CA information to be stored in a file on disk.

			### cache

			* Default: Windows: `%AppData%\npm-cache`, Posix: `~/.npm`
			* Type: path

			The location of npm's cache directory. See `npm-cache(1)`

			### cache-lock-stale

			* Default: 60000 (1 minute)
			* Type: Number

			The number of ms before cache folder lockfiles are considered stale.

			### cache-lock-retries

			* Default: 10
			* Type: Number

			Number of times to retry to acquire a lock on cache folder lockfiles.

			### cache-lock-wait

			* Default: 10000 (10 seconds)
			* Type: Number

			Number of ms to wait for cache lock files to expire.

			### cache-max

			* Default: Infinity
			* Type: Number

			The maximum time (in seconds) to keep items in the registry cache before
			re-checking against the registry.

			Note that no purging is done unless the `npm cache clean` command is
			explicitly used, and that only GET requests use the cache.

			### cache-min

			* Default: 10
			* Type: Number

			The minimum time (in seconds) to keep items in the registry cache before
			re-checking against the registry.

			Note that no purging is done unless the `npm cache clean` command is
			explicitly used, and that only GET requests use the cache.

			### cert

			* Default: `null`
			* Type: String

			A client certificate to pass when accessing the registry. Values should be in
			PEM format with newlines replaced by the string "\n". For example:

			cert="-----BEGIN CERTIFICATE-----\nXXXX\nXXXX\n-----END CERTIFICATE-----"

			It is _not_ the path to a certificate file (and there is no "certfile" option).

			### color

			* Default: true
			* Type: Boolean or `"always"`

			If false, never shows colors. If `"always"` then always shows colors.
			If true, then only prints color codes for tty file descriptors.

			### depth

			* Default: Infinity
			* Type: Number

			The depth to go when recursing directories for `npm ls`,
			`npm cache ls`, and `npm outdated`.

			For `npm outdated`, a setting of `Infinity` will be treated as `0`
			since that gives more useful information. To show the outdated status
			of all packages and dependents, use a large integer value,
			e.g., `npm outdated --depth 9999`

			### description

			* Default: true
			* Type: Boolean

			Show the description in `npm search`

			### dev

			* Default: false
			* Type: Boolean

			Install `dev-dependencies` along with packages.

			Note that `dev-dependencies` are also installed if the `npat` flag is
			set.

			### dry-run

			* Default: false
			* Type: Boolean

			Indicates that you don't want npm to make any changes and that it should
			only report what it would have done. This can be passed into any of the
			commands that modify your local installation, eg, `install`, `update`,
			`dedupe`, `uninstall`. This is NOT currently honored by network related
			commands, eg `dist-tags`, `owner`, `publish`, etc.

			### editor

			* Default: `EDITOR` environment variable if set, or `"vi"` on Posix,
			or `"notepad"` on Windows.
			* Type: path

			The command to run for `npm edit` or `npm config edit`.

			### engine-strict

			* Default: false
			* Type: Boolean

			If set to true, then npm will stubbornly refuse to install (or even
			consider installing) any package that claims to not be compatible with
			the current Node.js version.

			### force

			* Default: false
			* Type: Boolean

			Makes various commands more forceful.

			* lifecycle script failure does not block progress.
			* publishing clobbers previously published versions.
			* skips cache when requesting from the registry.
			* prevents checks against clobbering non-npm files.

			### fetch-retries

			* Default: 2
			* Type: Number

			The "retries" config for the `retry` module to use when fetching
			packages from the registry.

			### fetch-retry-factor

			* Default: 10
			* Type: Number

			The "factor" config for the `retry` module to use when fetching
			packages.

			### fetch-retry-mintimeout

			* Default: 10000 (10 seconds)
			* Type: Number

			The "minTimeout" config for the `retry` module to use when fetching
			packages.

			### fetch-retry-maxtimeout

			* Default: 60000 (1 minute)
			* Type: Number

			The "maxTimeout" config for the `retry` module to use when fetching
			packages.

			### git

			* Default: `"git"`
			* Type: String

			The command to use for git commands. If git is installed on the
			computer, but is not in the `PATH`, then set this to the full path to
			the git binary.

			### git-tag-version

			* Default: `true`
			* Type: Boolean

			Tag the commit when using the `npm version` command.

			### global

			* Default: false
			* Type: Boolean

			Operates in "global" mode, so that packages are installed into the
			`prefix` folder instead of the current working directory. See
			`npm-folders(5)` for more on the differences in behavior.

			* packages are installed into the `{prefix}/lib/node_modules` folder, instead of the
			current working directory.
			* bin files are linked to `{prefix}/bin`
			* man pages are linked to `{prefix}/share/man`

			### globalconfig

			* Default: {prefix}/etc/npmrc
			* Type: path

			The config file to read for global config options.

			### global-style

			* Default: false
			* Type: Boolean

			Causes npm to install the package into your local `node_modules` folder with
			the same layout it uses with the global `node_modules` folder. Only your
			direct dependencies will show in `node_modules` and everything they depend
			on will be flattened in their `node_modules` folders. This obviously will
			eliminate some deduping. If used with `legacy-bundling`, `legacy-bundling` will be
			preferred.

			### group

			* Default: GID of the current process
			* Type: String or Number

			The group to use when running package scripts in global mode as the root
			user.

			### heading

			* Default: `"npm"`
			* Type: String

			The string that starts all the debugging log output.

			### https-proxy

			* Default: null
			* Type: url

			A proxy to use for outgoing https requests. If the `HTTPS_PROXY` or
			`https_proxy` or `HTTP_PROXY` or `http_proxy` environment variables are set,
			proxy settings will be honored by the underlying `request` library.

			### if-present

			* Default: false
			* Type: Boolean

			If true, npm will not exit with an error code when `run-script` is invoked for
			a script that isn't defined in the `scripts` section of `package.json`. This
			option can be used when it's desirable to optionally run a script when it's
			present and fail if the script fails. This is useful, for example, when running
			scripts that may only apply for some builds in an otherwise generic CI setup.

			### ignore-scripts

			* Default: false
			* Type: Boolean

			If true, npm does not run scripts specified in package.json files.

			### init-module

			* Default: ~/.npm-init.js
			* Type: path

			A module that will be loaded by the `npm init` command. See the
			documentation for the
			[init-package-json](https://github.com/isaacs/init-package-json) module
			for more information, or npm-init(1).

			### init-author-name

			* Default: ""
			* Type: String

			The value `npm init` should use by default for the package author's name.

			### init-author-email

			* Default: ""
			* Type: String

			The value `npm init` should use by default for the package author's email.

			### init-author-url

			* Default: ""
			* Type: String

			The value `npm init` should use by default for the package author's homepage.

			### init-license

			* Default: "ISC"
			* Type: String

			The value `npm init` should use by default for the package license.

			### init-version

			* Default: "1.0.0"
			* Type: semver

			The value that `npm init` should use by default for the package
			version number, if not already set in package.json.

			### json

			* Default: false
			* Type: Boolean

			Whether or not to output JSON data, rather than the normal output.

			This feature is currently experimental, and the output data structures
			for many commands is either not implemented in JSON yet, or subject to
			change. Only the output from `npm ls --json` is currently valid.

			### key

			* Default: `null`
			* Type: String

			A client key to pass when accessing the registry. Values should be in PEM
			format with newlines replaced by the string "\n". For example:

			key="-----BEGIN PRIVATE KEY-----\nXXXX\nXXXX\n-----END PRIVATE KEY-----"

			It is _not_ the path to a key file (and there is no "keyfile" option).

			### legacy-bundling

			* Default: false
			* Type: Boolean

			Causes npm to install the package such that versions of npm prior to 1.4,
			such as the one included with node 0.8, can install the package. This
			eliminates all automatic deduping. If used with `global-style` this option
			will be preferred.

			### link

			* Default: false
			* Type: Boolean

			If true, then local installs will link if there is a suitable globally
			installed package.

			Note that this means that local installs can cause things to be
			installed into the global space at the same time. The link is only done
			if one of the two conditions are met:

			* The package is not already installed globally, or
			* the globally installed version is identical to the version that is
			being installed locally.

			### local-address

			* Default: undefined
			* Type: IP Address

			The IP address of the local interface to use when making connections
			to the npm registry. Must be IPv4 in versions of Node prior to 0.12.

			### loglevel

			* Default: "warn"
			* Type: String
			* Values: "silent", "error", "warn", "http", "info", "verbose", "silly"

			What level of logs to report. On failure, all logs are written to
			`npm-debug.log` in the current working directory.

			Any logs of a higher level than the setting are shown.
			The default is "warn", which shows warn and error output.

			### logstream

			* Default: process.stderr
			* Type: Stream

			This is the stream that is passed to the
			[npmlog](https://github.com/npm/npmlog) module at run time.

			It cannot be set from the command line, but if you are using npm
			programmatically, you may wish to send logs to somewhere other than
			stderr.

			If the `color` config is set to true, then this stream will receive
			colored output if it is a TTY.

			### long

			* Default: false
			* Type: Boolean

			Show extended information in `npm ls` and `npm search`.

			### maxsockets

			* Default: 50
			* Type: Number

			The maximum number of connections to use per origin (protocol/host/port
			combination). Passed to the `http` `Agent` used to make the request.

			### message

			* Default: "%s"
			* Type: String

			Commit message which is used by `npm version` when creating version commit.

			Any "%s" in the message will be replaced with the version number.

			### node-version

			* Default: process.version
			* Type: semver or false

			The node version to use when checking a package's `engines` map.

			### npat

			* Default: false
			* Type: Boolean

			Run tests on installation.

			### onload-script

			* Default: false
			* Type: path

			A node module to `require()` when npm loads. Useful for programmatic
			usage.

			### only

			* Default: null
			* Type: String

			When "dev" or "development" and running local `npm install` without any
			arguments, only devDependencies (and their dependencies) are installed.

			When "dev" or "development" and running local `npm ls`, `npm outdated`, or
			`npm update`, is an alias for `--dev`.

			When "prod" or "production" and running local `npm install` without any
			arguments, only non-devDependencies (and their dependencies) are
			installed.

			When "prod" or "production" and running local `npm ls`, `npm outdated`, or
			`npm update`, is an alias for `--production`.

			### optional

			* Default: true
			* Type: Boolean

			Attempt to install packages in the `optionalDependencies` object. Note
			that if these packages fail to install, the overall installation
			process is not aborted.

			### parseable

			* Default: false
			* Type: Boolean

			Output parseable results from commands that write to
			standard output.

			### prefix

			* Default: see npm-folders(5)
			* Type: path

			The location to install global items. If set on the command line, then
			it forces non-global commands to run in the specified folder.

			### production

			* Default: false
			* Type: Boolean

			Set to true to run in "production" mode.

			1. devDependencies are not installed at the topmost level when running
			local `npm install` without any arguments.
			2. Set the NODE_ENV="production" for lifecycle scripts.

			### progress

			* Default: true
			* Type: Boolean

			When set to `true`, npm will display a progress bar during time intensive
			operations, if `process.stderr` is a TTY.

			Set to `false` to suppress the progress bar.

			### proprietary-attribs

			* Default: true
			* Type: Boolean

			Whether or not to include proprietary extended attributes in the
			tarballs created by npm.

			Unless you are expecting to unpack package tarballs with something other
			than npm -- particularly a very outdated tar implementation -- leave
			this as true.

			### proxy

			* Default: null
			* Type: url

			A proxy to use for outgoing http requests. If the `HTTP_PROXY` or
			`http_proxy` environment variables are set, proxy settings will be
			honored by the underlying `request` library.

			### rebuild-bundle

			* Default: true
			* Type: Boolean

			Rebuild bundled dependencies after installation.

			### registry

			* Default: https://registry.npmjs.org/
			* Type: url

			The base URL of the npm package registry.

			### rollback

			* Default: true
			* Type: Boolean

			Remove failed installs.

			### save

			* Default: false
			* Type: Boolean

			Save installed packages to a package.json file as dependencies.

			When used with the `npm rm` command, it removes it from the `dependencies`
			object.

			Only works if there is already a package.json file present.

			### save-bundle

			* Default: false
			* Type: Boolean

			If a package would be saved at install time by the use of `--save`,
			`--save-dev`, or `--save-optional`, then also put it in the
			`bundleDependencies` list.

			When used with the `npm rm` command, it removes it from the
			bundledDependencies list.

			### save-dev

			* Default: false
			* Type: Boolean

			Save installed packages to a package.json file as `devDependencies`.

			When used with the `npm rm` command, it removes it from the
			`devDependencies` object.

			Only works if there is already a package.json file present.

			### save-exact

			* Default: false
			* Type: Boolean

			Dependencies saved to package.json using `--save`, `--save-dev` or
			`--save-optional` will be configured with an exact version rather than
			using npm's default semver range operator.

			### save-optional

			* Default: false
			* Type: Boolean

			Save installed packages to a package.json file as
			optionalDependencies.

			When used with the `npm rm` command, it removes it from the
			`devDependencies` object.

			Only works if there is already a package.json file present.

			### save-prefix

			* Default: '^'
			* Type: String

			Configure how versions of packages installed to a package.json file via
			`--save` or `--save-dev` get prefixed.

			For example if a package has version `1.2.3`, by default its version is
			set to `^1.2.3` which allows minor upgrades for that package, but after
			`npm config set save-prefix='~'` it would be set to `~1.2.3` which only allows
			patch upgrades.

			### scope

			* Default: ""
			* Type: String

			Associate an operation with a scope for a scoped registry. Useful when logging
			in to a private registry for the first time:
			`npm login --scope=@organization --registry=registry.organization.com`, which
			will cause `@organization` to be mapped to the registry for future installation
			of packages specified according to the pattern `@organization/package`.

			### searchopts

			* Default: ""
			* Type: String

			Space-separated options that are always passed to search.

			### searchexclude

			* Default: ""
			* Type: String

			Space-separated options that limit the results from search.

			### searchsort

			* Default: "name"
			* Type: String
			* Values: "name", "-name", "date", "-date", "description",
			"-description", "keywords", "-keywords"

			Indication of which field to sort search results by. Prefix with a `-`
			character to indicate reverse sort.

			### shell

			* Default: SHELL environment variable, or "bash" on Posix, or "cmd" on
			Windows
			* Type: path

			The shell to run for the `npm explore` command.

			### shrinkwrap

			* Default: true
			* Type: Boolean

			If set to false, then ignore `npm-shrinkwrap.json` files when
			installing.

			### sign-git-tag

			* Default: false
			* Type: Boolean

			If set to true, then the `npm version` command will tag the version
			using `-s` to add a signature.

			Note that git requires you to have set up GPG keys in your git configs
			for this to work properly.

			### strict-ssl

			* Default: true
			* Type: Boolean

			Whether or not to do SSL key validation when making requests to the
			registry via https.

			See also the `ca` config.

			### tag

			* Default: latest
			* Type: String

			If you ask npm to install a package and don't tell it a specific version, then
			it will install the specified tag.

			Also the tag that is added to the package@version specified by the `npm
			tag` command, if no explicit tag is given.

			### tag-version-prefix

			* Default: `"v"`
			* Type: String

			If set, alters the prefix used when tagging a new version when performing a
			version increment using `npm-version`. To remove the prefix altogether, set it
			to the empty string: `""`.

			Because other tools may rely on the convention that npm version tags look like
			`v1.0.0`, _only use this property if it is absolutely necessary_. In
			particular, use care when overriding this setting for public packages.

			### tmp

			* Default: TMPDIR environment variable, or "/tmp"
			* Type: path

			Where to store temporary files and folders. All temp files are deleted
			on success, but left behind on failure for forensic purposes.

			### unicode

			* Default: false on windows, true on mac/unix systems with a unicode locale
			* Type: Boolean

			When set to true, npm uses unicode characters in the tree output. When
			false, it uses ascii characters to draw trees.

			### unsafe-perm

			* Default: false if running as root, true otherwise
			* Type: Boolean

			Set to true to suppress the UID/GID switching when running package
			scripts. If set explicitly to false, then installing as a non-root user
			will fail.

			### usage

			* Default: false
			* Type: Boolean

			Set to show short usage output (like the -H output)
			instead of complete help when doing `npm-help(1)`.

			### user

			* Default: "nobody"
			* Type: String or Number

			The UID to set to when running package scripts as root.

			### userconfig

			* Default: ~/.npmrc
			* Type: path

			The location of user-level configuration settings.

			### umask

			* Default: 022
			* Type: Octal numeric string in range 0000..0777 (0..511)

			The "umask" value to use when setting the file creation mode on files
			and folders.

			Folders and executables are given a mode which is `0777` masked against
			this value. Other files are given a mode which is `0666` masked against
			this value. Thus, the defaults are `0755` and `0644` respectively.

			### user-agent

			* Default: node/{process.version} {process.platform} {process.arch}
			* Type: String

			Sets a User-Agent to the request header

			### version

			* Default: false
			* Type: boolean

			If true, output the npm version and exit successfully.

			Only relevant when specified explicitly on the command line.

			### versions

			* Default: false
			* Type: boolean

			If true, output the npm version as well as node's `process.versions` map, and
			exit successfully.

			Only relevant when specified explicitly on the command line.

			### viewer

			* Default: "man" on Posix, "browser" on Windows
			* Type: path

			The program to use to view help content.

			Set to `"browser"` to view html help content in the default web browser.
