.SH "NAME"
\fBconfig\fR - More than you probably want to know about npm configuration
.SS "Description"
.P
This article details npm configuration in general. To learn about the \fBconfig\fR command, see npm help config.
.P
npm gets its configuration values from the following sources, sorted by priority:
.SS "Command Line Flags"
.P
Putting \fB--foo bar\fR on the command line sets the \fBfoo\fR configuration parameter to \fB"bar"\fR. A \fB--\fR argument tells the cli parser to stop reading flags. Using \fB--flag\fR without specifying any value will set the value to \fBtrue\fR.
.P
Example: \fB--flag1 --flag2\fR will set both configuration parameters to \fBtrue\fR, while \fB--flag1 --flag2 bar\fR will set \fBflag1\fR to \fBtrue\fR, and \fBflag2\fR to \fBbar\fR. Finally, \fB--flag1 --flag2 -- bar\fR will set both configuration parameters to \fBtrue\fR, and the \fBbar\fR is taken as a command argument.
.SS "Environment Variables"
.P
Any environment variables that start with \fBnpm_config_\fR will be interpreted as a configuration parameter. For example, putting \fBnpm_config_foo=bar\fR in your environment will set the \fBfoo\fR configuration parameter to \fBbar\fR. Any environment configurations that are not given a value will be given the value of \fBtrue\fR. Config values are case-insensitive, so \fBNPM_CONFIG_FOO=bar\fR will work the same. However, please note that inside npm help scripts npm will set its own environment variables and Node will prefer those lowercase versions over any uppercase ones that you might set. For details see \fBthis issue\fR \fI\(lahttps://github.com/npm/npm/issues/14528\(ra\fR.
.P
Notice that you need to use underscores instead of dashes, so \fB--allow-same-version\fR would become \fBnpm_config_allow_same_version=true\fR.
.SS "npmrc Files"
.P
The four relevant files are:
.RS 0
.IP \(bu 4
per-project configuration file (\fB/path/to/my/project/.npmrc\fR)
.IP \(bu 4
per-user configuration file (defaults to \fB$HOME/.npmrc\fR; configurable via CLI option \fB--userconfig\fR or environment variable \fB$NPM_CONFIG_USERCONFIG\fR)
.IP \(bu 4
global configuration file (defaults to \fB$PREFIX/etc/npmrc\fR; configurable via CLI option \fB--globalconfig\fR or environment variable \fB$NPM_CONFIG_GLOBALCONFIG\fR)
.IP \(bu 4
npm's built-in configuration file (\fB/path/to/npm/npmrc\fR)
.RE 0

.P
See npm help npmrc for more details.
.SS "Default Configs"
.P
Run \fBnpm config ls -l\fR to see a set of configuration parameters that are internal to npm, and are defaults if nothing else is specified.
.SS "Shorthands and Other CLI Niceties"
.P

If the specified configuration param resolves unambiguously to a known configuration parameter, then it is expanded to that configuration parameter. For example:
.P
.RS 2
.nf
npm ls --par
# same as:
npm ls --parseable
.fi
.RE
.P
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:
.P

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

.SS "\fB_auth\fR"
.RS 0
.IP \(bu 4
Default: null
.IP \(bu 4
Type: null or String
.RE 0

.P
A basic-auth string to use when authenticating against the npm registry. This will ONLY be used to authenticate against the npm registry. For other registries you will need to scope it like "//other-registry.tld/:_auth"
.P
Warning: This should generally not be set via a command-line option. It is safer to use a registry-provided authentication bearer token stored in the ~/.npmrc file by running \fBnpm login\fR.
.SS "\fBaccess\fR"
.RS 0
.IP \(bu 4
Default: 'public' for new packages, existing packages it will not change the current level
.IP \(bu 4
Type: null, "restricted", or "public"
.RE 0

.P
If you do not want your scoped package to be publicly viewable (and installable) set \fB--access=restricted\fR.
.P
Unscoped packages can not be set to \fBrestricted\fR.
.P
Note: This defaults to not changing the current access level for existing packages. Specifying a value of \fBrestricted\fR or \fBpublic\fR during publish will change the access for an existing package the same way that \fBnpm access set
status\fR would.
.SS "\fBall\fR"

.RE 0

.P
If passed to \fBnpm install\fR, will rebuild the npm tree such that only versions that were available \fBon or before\fR the \fB--before\fR time get installed. If there's no versions available for the current set of direct dependencies, the command will error.
.P
If the requested version is a \fBdist-tag\fR and the given tag does not pass the \fB--before\fR filter, the most recent version less than or equal to that tag will be used. For example, \fBfoo@latest\fR might install \fBfoo@1.2\fR even though \fBlatest\fR is \fB2.0\fR.
.SS "\fBbin-links\fR"
.RS 0
.IP \(bu 4
Default: true
.IP \(bu 4
Type: Boolean
.RE 0

.P
Tells npm to create symlinks (or \fB.cmd\fR shims on Windows) for package executables.
.P
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.
.SS "\fBbrowser\fR"

Set to \fBnull\fR to only allow "known" registrars, or to a specific CA cert to trust only that specific signing authority.

The "umask" value to use when setting the file creation mode on files and folders.
.P
Folders and executables are given a mode which is \fB0o777\fR masked against this value. Other files are given a mode which is \fB0o666\fR masked against this value.
.P
Note that the underlying system will \fIalso\fR apply its own umask value to files and folders that are created, and npm does not circumvent this, but rather adds the \fB--umask\fR config to it.
.P
Thus, the effective default umask value on most POSIX systems is 0o22, meaning that folders and executables are created with a mode of 0o755 and other files are created with a mode of 0o644.
