npm-config(1) -- Manage the npm configuration file ================================================== ## SYNOPSIS npm config set [--global] npm config get npm config delete npm config list npm config edit npm get npm set [--global] ## DESCRIPTION npm gets its configuration values from 6 sources, in this 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. ### Per-user config file `$HOME/.npmrc` (or the `userconfig` param, if set above) This file is an ini-file formatted list of `key = value` parameters. ### Global config file `$PREFIX/etc/npmrc` (or the `globalconfig` param, if set above): This file is an ini-file formatted list of `key = value` parameters ### Built-in config file `path/to/npm/itself/npmrc` This is an unchangeable "builtin" configuration file that npm keeps consistent across updates. Set fields in here using the `./configure` script that comes with npm. This is primarily for distribution maintainers to override default configs in a standard and consistent manner. ### Default Configs A set of configuration parameters that are internal to npm, and are defaults if nothing else is specified. ## Sub-commands Config supports the following sub-commands: ### set npm config set key value Sets the config key to the value. If value is omitted, then it sets it to "true". ### get npm config get key Echo the config value to stdout. ### list npm config list Show all the config settings. ### delete npm config delete key Deletes the key from all configuration files. ### edit npm config edit Opens the config file in an editor. Use the `--global` flag to edit the global config. ## 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` * `-l`: `--long` * `-m`: `--message` * `-p`, `--porcelain`: `--parseable` * `-reg`: `--registry` * `-v`: `--version` * `-f`: `--force` * `-l`: `--long` * `-desc`: `--description` * `-S`: `--save` * `-D`: `--save-dev` * `-O`: `--save-optional` * `-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(1)`) the package.json "config" keys are overwritten in the environment if there is a config param of `[@]:`. 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 ## Config Settings ### always-auth * Default: false * Type: Boolean Force npm to always require authentication when accessing the registry, even for `GET` requests. ### bin-publish * Default: false * Type: Boolean If set to true, then binary packages will be created on publish. This is the way to opt into the "bindist" behavior described below. ### bindist * Default: Unstable node versions, `null`, otherwise `"--"` * Type: String or `null` Experimental: on stable versions of node, binary distributions will be created with this tag. If a user then installs that package, and their `bindist` tag is found in the list of binary distributions, they will get that prebuilt version. Pre-build node packages have their preinstall, install, and postinstall scripts stripped (since they are run prior to publishing), and do not have their `build` directories automatically ignored. It's yet to be seen if this is a good idea. ### browser * Default: OS X: `"open"`, others: `"google-chrome"` * Type: String The browser that is called by the `npm docs` command to open websites. ### ca * Default: The npm CA certificate * Type: String or null The Certificate Authority signing certificate that is trusted for SSL connections to the registry. Set to `null` to only allow "known" registrars, or to a specific CA cert to trust only that specific signing authority. See also the `strict-ssl` config. ### cache * Default: Windows: `%APPDATA%\npm-cache`, Posix: `~/.npm` * Type: path The location of npm's cache directory. See `npm-cache(1)` ### 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: 0 * 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. ### color * Default: true on Posix, false on Windows * 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. ### coverage * Default: false * Type: Boolean A flag to tell test-harness to run with their coverage options enabled, if they respond to the `npm_config_coverage` environment variable. ### depth * Default: Infinity * Type: Number The depth to go when recursing directories for `npm ls` and `npm cache ls`. ### 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. ### 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`. ### 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. ### 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. ### 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(1)` for more on the differences in behavior. * packages are installed into the `prefix/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. ### globalignorefile * Default: {prefix}/etc/npmignore * Type: path The config file to read for global ignore patterns to apply to all users and all projects. If not found, but there is a "gitignore" file in the same directory, then that will be used instead. ### 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. ### https-proxy * Default: the `HTTPS_PROXY` or `https_proxy` or `HTTP_PROXY` or `http_proxy` environment variables. * Type: url A proxy to use for outgoing https requests. ### user-agent * Default: npm/{npm.version} node/{process.version} * Type: String Sets a User-Agent to the request header ### ignore * Default: "" * Type: string A white-space separated list of glob patterns of files to always exclude from packages when building tarballs. ### 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.version * Default: "0.0.0" * Type: semver The value `npm init` should use by default for the package version. ### 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. ### 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. ### 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. ### loglevel * Default: "http" * Type: String * Values: "silent", "win", "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 "http", which shows http, warn, and error output. ### long * Default: false * Type: Boolean Show extended information in `npm ls` ### 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 package's "engines" hash. ### npat * Default: false * Type: Boolean Run tests on installation and report results to the `npaturl`. ### npaturl * Default: Not yet implemented * Type: url The url to report npat test results. ### onload-script * Default: false * Type: path A node module to `require()` when npm loads. Useful for programmatic usage. ### parseable * Default: false * Type: Boolean Output parseable results from commands that write to standard output. ### prefix * Default: node's process.installPrefix * 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. ### 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: `HTTP_PROXY` or `http_proxy` environment variable, or null * Type: url A proxy to use for outgoing http requests. ### 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. Only works if there is already a package.json file present. ### save-dev * Default: false * Type: Boolean Save installed packages to a package.json file as devDependencies. Only works if there is already a package.json file present. ### save-optional * Default: false * Type: Boolean Save installed packages to a package.json file as optionalDependencies. Only works if there is already a package.json file present. ### 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. ### 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. ### 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: true * 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. ### username * Default: null * Type: String The username on the npm registry. Set with `npm adduser` ### userconfig * Default: ~/.npmrc * Type: path The location of user-level configuration settings. ### userignorefile * Default: ~/.npmignore * Type: path The location of a user-level ignore file to apply to all packages. If not found, but there is a .gitignore file in the same directory, then that will be used instead. ### umask * Default: 022 * Type: Octal numeric string 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. ### 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` hash, 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. ### yes * Default: null * Type: Boolean or null If set to `null`, then prompt the user for responses in some circumstances. If set to `true`, then answer "yes" to any prompt. If set to `false` then answer "no" to any prompt. ## SEE ALSO * npm-folders(1) * npm(1)
