* Tells you what's out of date.
* Provides a link to the package's documentation so you can decide if you want the update.
* Kindly informs you if a dependency is not being used in your code.
* Works on your globally installed packages too, via -g.
* Interactive Update for less typing and fewer typos, via -u.
* Supports public and private @scoped/packages.
* Supports ES6-style import from syntax.
* Upgrades your modules using your installed version of npm, including the new npm@3, so dependencies go where you expect them.
* Works with any public npm registry, private registries, and alternate registries like Sinopia.
* Does not query registries for packages with private: true in their package.json.
* Emoji in a command-line app, because command-line apps can be fun too.
* Works with npm@2 and npm@3, as well as newer alternative installers like ied and pnpm.

* Node >= 10.9.0

This is the easiest way to use npm-check.
$3
``
bash
$ npm install -g npm-check
`$3
bash
$ npm-check
`
The result should look like the screenshot, or something nice when your packages are all up-to-date and in use.
When updates are required it will return a non-zero response code that you can use in your CI tools.

Usage
$ npm-check Path
Where to check. Defaults to current directory. Use -g for checking global modules.
Options
-u, --update Interactive update.
-y, --update-all Uninteractive update. Apply all updates without prompting.
-g, --global Look at global modules.
-s, --skip-unused Skip check for unused packages.
-p, --production Skip devDependencies.
-d, --dev-only Look at devDependencies only (skip dependencies).
-i, --ignore Ignore dependencies based on succeeding glob.
-E, --save-exact Save exact version (x.y.z) instead of caret (^x.y.z) in package.json.
--specials List of depcheck specials to include in check for unused dependencies.
--no-color Force or disable color output.
--no-emoji Remove emoji support. No emoji in default in CI environments.
--debug Show debug output. Throw in a gist when creating issues on github.
Examples
$ npm-check # See what can be updated, what isn't being used.
$ npm-check ../foo # Check another path.
$ npm-check -gu # Update globally installed modules by picking which ones to upgrade.
####
Show an interactive UI for choosing which modules to update.
Automatically updates versions referenced in the
._Based on recommendations from the
npm team, npm-check only updates using npm install, not npm update.
To avoid using more than one version of npm in one directory, npm-check will automatically install updated modules
using the version of npm installed globally._
##### Update using ied or pnpm
Set environment variable
NPM_CHECK_INSTALLER to the name of the installer you wish to use.`bash
NPM_CHECK_INSTALLER=pnpm npm-check -u
pnpm install --save-dev foo@version --color=always
`You can also use this for dry-run testing:
bash
NPM_CHECK_INSTALLER=echo npm-check -u
`####
Updates your dependencies like
, just without any prompt. This is especially useful if you want to automate your dependency updates with npm-check.####
-g, --globalCheck the versions of your globally installed packages.
If the value of
is set, it will override the default path of global node_modules returned by package global-modules._Tip: Use
npm-check -u -g to do a safe interactive update of global modules, including npm itself._####
-s, --skip-unusedBy default
will let you know if any of your modules are not being used by looking at require statements
in your code.This option will skip that check.
This is enabled by default when using
global or update.####
-p, --productionBy default
will look at packages listed as dependencies and devDependencies.This option will let it ignore outdated and unused checks for packages listed as
devDependencies.####
-d, --dev-onlyIgnore
and only check devDependencies.This option will let it ignore outdated and unused checks for packages listed as
dependencies.####
-i, --ignoreIgnore dependencies that match specified glob.
will ignore all dependencies starting with 'babel-'.####
-E, --save-exactInstall packages using
, meaning exact versions will be saved in package.json.Applies to both
dependencies and devDependencies.####
--specialsCheck special (e.g. config) files when looking for unused dependencies.
will look in the scripts section of package.json and in webpack config.See https://github.com/depcheck/depcheck#special for more information.
####
--color, --no-colorEnable or disable color support.
By default
uses colors if they are available.####
--emoji, --no-emojiEnable or disable emoji support. Useful for terminals that don't support them. Automatically disabled in CI servers.
####
Enable or disable the spinner. Useful for terminals that don't support them. Automatically disabled in CI servers.

The API is here in case you want to wrap this with your CI toolset.
js
const npmCheck = require('npm-check');npmCheck(options)
.then(currentState => console.log(currentState.get('packages')));
`####
* Interactive update.
* default is
####
* Check global modules.
* default is
* is automatically set with this option.####
skipUnused* Skip checking for unused packages.
* default is
####
* Ignore
.
* This is called --production on the command line to match npm.
* default is false####
* Ignore
and only check devDependencies.
* default is false####
* Ignore dependencies that match specified glob.
* default is
####
* Update package.json with exact version
instead of semver range ^x.y.z.
* default is false####
* Show debug output. Throw in a gist when creating issues on github.
* default is
####
* Override where
checks.
* default is process.cwd()####
special parsers to include.
* default is ''####
The result of the promise is a
object, look in state.js to see how it works.You will probably want
currentState.get('packages') to get an array of packages and the state of each of them.Each item in the array will look like the following:
`js
{
moduleName: 'lodash', // name of the module.
homepage: 'https://lodash.com/', // url to the home page.
regError: undefined, // error communicating with the registry
pkgError: undefined, // error reading the package.json
latest: '4.7.0', // latest according to the registry.
installed: '4.6.1', // version installed
isInstalled: true, // Is it installed?
notInstalled: false, // Is it installed?
packageWanted: '4.7.0', // Requested version from the package.json.
packageJson: '^4.6.1', // Version or range requested in the parent package.json.
devDependency: false, // Is this a devDependency?
usedInScripts: undefined, // Array of scripts in package.json that use this module.
mismatch: false, // Does the version installed not match the range in package.json?
semverValid: '4.6.1', // Is the installed version valid semver?
easyUpgrade: true, // Will running just npm install upgrade the module?
bump: 'minor', // What kind of bump is required to get the latest, such as patch, minor, major.
unused: false // Is this module used in the code?
},
`You will also see this if you use
on the command line.$3
Additional options can be sent to the depcheck process. See depcheck API. Create a .npmcheckrc{.json,.yml,.js} file and set the depcheck options under depcheck property.For example, to skip packages for unused check, but still want them in the outdated check (so can't use the --ignore option):
`
.npmcheckrc
depcheck:
ignoreMatches: ["replace-in-file","snyk","sonarqube-scanner"]
$3
* npm outdated - awkward output, requires --depth=0 to be grokable.
* david - does not work with private registries.
* update-notifier - for single modules, not everything in package.json.
* depcheck - only part of the puzzle. npm-check uses depcheck.
