6 config - More than you probably want to know about npm configuration
7 Description
9 npm gets its configuration values from the following sources, sorted by
10 priority:
11 Command Line Flags
13 Putting --foo bar on the command line sets the foo configuration param‐
14 eter to "bar". A -- argument tells the cli parser to stop reading
15 flags. Using --flag without specifying any value will set the value to
16 true.
17 Example: --flag1 --flag2 will set both configuration parameters to
19 true, while --flag1 --flag2 bar will set flag1 to true, and flag2 to
20 bar. Finally, --flag1 --flag2 -- bar will set both configuration
21 parameters to true, and the bar is taken as a command argument.
22 Environment Variables
24 Any environment variables that start with npm_config_ will be inter‐
25 preted as a configuration parameter. For example, putting npm_con‐
26 fig_foo=bar in your environment will set the foo configuration parame‐
27 ter to bar. Any environment configurations that are not given a value
28 will be given the value of true. Config values are case-insensitive,
29 so NPM_CONFIG_FOO=bar will work the same. However, please note that
30 inside npm help scripts npm will set its own environment variables and
31 Node will prefer those lowercase versions over any uppercase ones that
32 you might set. For details see this issue
33 https://github.com/npm/npm/issues/14528.
34 Notice that you need to use underscores instead of dashes, so
36 --allow-same-version would become npm_config_allow_same_version=true.
37 npmrc Files
39 The four relevant files are:
40 · per-project configuration file (/path/to/my/project/.npmrc)
42 · per-user configuration file (defaults to $HOME/.npmrc; configurable
44 via CLI option --userconfig or environment variable $NPM_CONFIG_USER‐
45 CONFIG)
46 · global configuration file (defaults to $PREFIX/etc/npmrc; config‐
48 urable via CLI option --globalconfig or environment variable
49 $NPM_CONFIG_GLOBALCONFIG)
50 · npm's built-in configuration file (/path/to/npm/npmrc)
52 See npm help npmrc for more details.
55 Default Configs
57 Run npm config ls -l to see a set of configuration parameters that are
58 internal to npm, and are defaults if nothing else is specified.
59 Shorthands and Other CLI Niceties
61 The following shorthands are parsed on the command-line:
62 · -v: --version
64 · -h, -?, --help, -H: --usage
66 · -s, --silent: --loglevel silent
68 · -q, --quiet: --loglevel warn
70 · -d: --loglevel info
72 · -dd, --verbose: --loglevel verbose
74 · -ddd: --loglevel silly
76 · -g: --global
78 · -C: --prefix
80 · -l: --long
82 · -m: --message
84 · -p, --porcelain: --parseable
86 · -reg: --registry
88 · -f: --force
90 · -desc: --description
92 · -S: --save
94 · -P: --save-prod
96 · -D: --save-dev
98 · -O: --save-optional
100 · -B: --save-bundle
102 · -E: --save-exact
104 · -y: --yes
106 · -n: --yes false
108 · ll and la commands: ls --long
110 If the specified configuration param resolves unambiguously to a known
113 configuration parameter, then it is expanded to that configuration
114 parameter. For example:
115 npm ls --par
117 # same as:
118 npm ls --parseable
119 If multiple single-character shorthands are strung together, and the
121 resulting combination is unambiguously not some other configuration
122 param, then it is expanded to its various component pieces. For exam‐
123 ple:
124 npm ls -gpld
126 # same as:
127 npm ls --global --parseable --long --loglevel info
128 Per-Package Config Settings
130 When running scripts (see npm help scripts) the package.json "config"
131 keys are overwritten in the environment if there is a config param of
132 <name>[@<version>]:<key>. For example, if the package.json has this:
133 { "name" : "foo"
135 , "config" : { "port" : "8080" }
136 , "scripts" : { "start" : "node server.js" } }
137 and the server.js is this:
139 http.createServer(...).listen(process.env.npm_package_config_port)
141 then the user could change the behavior by doing:
143 npm config set foo:port 80
145 See npm help package.json for more information.
147 Config Settings
149 access
150 · Default: restricted
151 · Type: Access
153 When publishing scoped packages, the access level defaults to
156 restricted. If you want your scoped package to be publicly viewable
157 (and installable) set --access=public. The only valid values for access
158 are public and restricted. Unscoped packages always have an access
159 level of public.
160 allow-same-version

172 · Type: Boolean
174 Force npm to always require authentication when accessing the registry,
177 even for GET requests.
178 also
180 · Default: null
181 · Type: String
183 When "dev" or "development" and running local npm shrinkwrap, npm out‐
186 dated, or npm update, is an alias for --dev.
187 audit
189 · Default: true
190 · Type: Boolean
192 When "true" submit audit reports alongside npm install runs to the
195 default registry and all registries configured for scopes. See the

214 before
216 · Alias: enjoy-by
217 · Default: null
219 · Type: Date
221 If passed to npm install, will rebuild the npm tree such that only ver‐
224 sions that were available on or before the --before time get installed.
225 If there's no versions available for the current set of direct depen‐
226 dencies, the command will error.
227 If the requested version is a dist-tag and the given tag does not pass
229 the --before filter, the most recent version less than or equal to that
230 tag will be used. For example, foo@latest might install foo@1.2 even
231 though latest is 2.0.
232 bin-links
234 · Default: true
235 · Type: Boolean
237 Tells npm to create symlinks (or .cmd shims on Windows) for package
240 executables.
241 Set to false to have it not do this. This can be used to work around
243 the fact that some file systems don't support symlinks, even on osten‐
244 sibly Unix systems.
245 browser
247 · Default: OS X: "open", Windows: "start", Others: "xdg-open"
248 · Type: String

266 Set to null to only allow "known" registrars, or to a specific CA cert
268 to trust only that specific signing authority.
269 Multiple CAs can be trusted by specifying an array of certificates:
271 ca[]="..."
273 ca[]="..."
274 See also the strict-ssl config.
276 cafile
278 · Default: null
279 · Type: path
281 A path to a file containing one or multiple Certificate Authority sign‐
284 ing certificates. Similar to the ca setting, but allows for multiple

286 cache
288 · Default: Windows: %AppData%\npm-cache, Posix: ~/.npm
289 · Type: path
291 The location of npm's cache directory. See npm help cache

329 cache-min
331 · Default: 10
332 · Type: Number
334 DEPRECATED: This option has been deprecated in favor of --prefer-off‐
337 line.
338 --cache-min=9999 (or bigger) is an alias for --prefer-offline.
340 cert
342 · Default: null
343 · Type: String
345 A client certificate to pass when accessing the registry. Values
348 should be in PEM format (Windows calls it "Base-64 encoded X.509
349 (.CER)") with newlines replaced by the string "\n". For example:
350 cert="-----BEGIN CERTIFICATE-----\nXXXX\nXXXX\n-----END CERTIFICATE-----"
352 It is not the path to a certificate file (and there is no "certfile"
354 option).
355 cidr
357 · Default: null
358 · Type: String, Array, null
360 This is a list of CIDR address to be used when configuring limited
363 access tokens with the npm token create command.

378 · Default: Infinity
379 · Type: Number
381 The depth to go when recursing directories for npm ls, npm cache ls,
384 and npm outdated.
385 For npm outdated, a setting of Infinity will be treated as 0 since that
387 gives more useful information. To show the outdated status of all
388 packages and dependents, use a large integer value, e.g., npm outdated
389 --depth 9999
390 description
392 · Default: true
393 · Type: Boolean

534 global
536 · Default: false
537 · Type: Boolean
539 Operates in "global" mode, so that packages are installed into the pre‐
542 fix folder instead of the current working directory. See npm help
543 folders for more on the differences in behavior.
544 · packages are installed into the {prefix}/lib/node_modules folder,
546 instead of the current working directory.

562 · Default: false
563 · Type: Boolean
565 Causes npm to install the package into your local node_modules folder
568 with the same layout it uses with the global node_modules folder. Only
569 your direct dependencies will show in node_modules and everything they
570 depend on will be flattened in their node_modules folders. This obvi‐
571 ously will eliminate some deduping. If used with legacy-bundling,
572 legacy-bundling will be preferred.
573 group

599 proxy settings will be honored by the underlying request library.
600 if-present
602 · Default: false
603 · Type: Boolean
605 If true, npm will not exit with an error code when run-script is
608 invoked for a script that isn't defined in the scripts section of pack‐
609 age.json. This option can be used when it's desirable to optionally run
610 a script when it's present and fail if the script fails. This is use‐
611 ful, for example, when running scripts that may only apply for some
612 builds in an otherwise generic CI setup.
613 ignore-prepublish

616 · Type: Boolean
618 If true, npm will not run prepublish scripts.

634 A module that will be loaded by the npm init command. See the documen‐
637 tation for the init-package-json https://github.com/isaacs/init-pack‐
638 age-json module for more information, or npm help init.
639 init-author-name
641 · Default: ""
642 · Type: String
644 The value npm init should use by default for the package author's name.
647 init-author-email

667 · Default: "ISC"
668 · Type: String
670 The value npm init should use by default for the package license.
673 init-version
675 · Default: "1.0.0"
676 · Type: semver
678 The value that npm init should use by default for the package version
681 number, if not already set in package.json.
682 json
684 · Default: false
685 · Type: Boolean
687 Whether or not to output JSON data, rather than the normal output.
690 This feature is currently experimental, and the output data structures
692 for many commands is either not implemented in JSON yet, or subject to
693 change. Only the output from npm ls --json and npm search --json are
694 currently valid.
695 key
697 · Default: null
698 · Type: String
700 A client key to pass when accessing the registry. Values should be in
703 PEM format with newlines replaced by the string "\n". For example:

706 It is not the path to a key file (and there is no "keyfile" option).
708 legacy-bundling
710 · Default: false
711 · Type: Boolean
713 Causes npm to install the package such that versions of npm prior to
716 1.4, such as the one included with node 0.8, can install the package.
717 This eliminates all automatic deduping. If used with global-style this
718 option will be preferred.
719 link
721 · Default: false
722 · Type: Boolean
724 If true, then local installs will link if there is a suitable globally
727 installed package.
728 Note that this means that local installs can cause things to be
730 installed into the global space at the same time. The link is only
731 done if one of the two conditions are met:
732 · The package is not already installed globally, or
734 · the globally installed version is identical to the version that is
736 being installed locally.
737 local-address
740 · Default: undefined

761 "notice".
762 logstream
764 · Default: process.stderr
765 · Type: Stream
767 This is the stream that is passed to the npmlog
770 https://github.com/npm/npmlog module at run time.
771 It cannot be set from the command line, but if you are using npm pro‐
773 grammatically, you may wish to send logs to somewhere other than
774 stderr.
775 If the color config is set to true, then this stream will receive col‐
777 ored output if it is a TTY.
778 logs-max
780 · Default: 10
781 · Type: Number
783 The maximum number of log files to store.

820 The registry you want to send cli metrics to if send-metrics is true.
823 node-options
825 · Default: null
826 · Type: String
828 Options to pass through to Node.js via the NODE_OPTIONS environment
831 variable. This does not impact how npm itself is executed but it does
832 impact how lifecycle scripts are called.
833 node-version
835 · Default: process.version
836 · Type: semver or false
838 The node version to use when checking a package's engines map.
841 noproxy

844 · Type: String or Array
846 A comma-separated string or an array of domain extensions that a proxy
849 should not be used for.
850 offline
852 · Default: false
853 · Type: Boolean

873 When "dev" or "development" and running local npm install without any
876 arguments, only devDependencies (and their dependencies) are installed.
877 When "dev" or "development" and running local npm ls, npm outdated, or
879 npm update, is an alias for --dev.
880 When "prod" or "production" and running local npm install without any
882 arguments, only non-devDependencies (and their dependencies) are
883 installed.
884 When "prod" or "production" and running local npm ls, npm outdated, or
886 npm update, is an alias for --production.
887 optional
889 · Default: true
890 · Type: Boolean

895 that if these packages fail to install, the overall installation
896 process is not aborted.
897 otp
899 · Default: null
900 · Type: Number
902 This is a one-time password from a two-factor authenticator. It's
905 needed when publishing or changing package permissions with npm access.
906 package-lock
908 · Default: true
909 · Type: Boolean
911 If set to false, then ignore package-lock.json files when installing.
914 This will also prevent writing package-lock.json if save is true.
915 When package package-locks are disabled, automatic pruning of extrane‐
917 ous modules will also be disabled. To remove extraneous modules with
918 package-locks disabled use npm prune.
919 This option is an alias for --shrinkwrap.
921 package-lock-only
923 · Default: false
924 · Type: Boolean
926 If set to true, it will update only the package-lock.json, instead of
929 checking node_modules and downloading dependencies.
930 parseable
932 · Default: false
933 · Type: Boolean
935 Output parseable results from commands that write to standard output.
938 For npm search, this will be tab-separated table format.
939 prefer-offline
941 · Default: false
942 · Type: Boolean
944 If true, staleness checks for cached data will be bypassed, but missing
947 data will be requested from the server. To force full offline mode, use
948 --offline.
949 This option is effectively equivalent to --cache-min=9999999.
951 prefer-online
953 · Default: false

960 prefix
962 · Default: see npm help folders
963 · Type: path
965 The location to install global items. If set on the command line, then
968 it forces non-global commands to run in the specified folder.
969 preid
971 · Default: ""

1071 dencies list.
1072 save-prod
1074 · Default: false
1075 · Type: Boolean

1123 · Type: String
1125 Configure how versions of packages installed to a package.json file via
1128 --save or --save-dev get prefixed.
1129 For example if a package has version 1.2.3, by default its version is
1131 set to ^1.2.3 which allows minor upgrades for that package, but after
1132 npm config set save-prefix='~' it would be set to ~1.2.3 which only
1133 allows patch upgrades.

1165 one which it is running.
1166 If set to false, never modify PATH with that.
1168 If set to "warn-only", never modify PATH but print a warning if npm
1170 thinks that you may want to run it with true, e.g. because the node
1171 executable in the PATH is not the one npm was invoked with.
1172 If set to auto, only add that directory to the PATH environment vari‐
1174 able if the node executable with which npm was invoked and the one that
1175 is found first on the PATH are different.

1314 ing a version increment using npm-version. To remove the prefix alto‐
1315 gether, set it to the empty string: "".
1316 Because other tools may rely on the convention that npm version tags
1318 look like v1.0.0, only use this property if it is absolutely necessary.
1319 In particular, use care when overriding this setting for public pack‐
1320 ages.
