npm-check-updates upgrades your package.json dependencies to the latest versions, ignoring specified versions.
- maintains existing semantic versioning policies, i.e.
"react": "^17.0.2"to"react": "^18.3.1". - only modifies package.json file. Run
npm installto update your installed packages and package-lock.json. - sensible defaults, but highly customizable
- compatible with npm, yarn, pnpm, deno, and bun
- CLI and module usage
Install globally to use npm-check-updates or the shorter ncu:
npm install -g npm-check-updatesOr run with npx (only the long form is supported):
npx npm-check-updatesCheck the latest versions of all project dependencies:
$ ncu

ncu chalk, mocha, react
ncu -f "chalk mocha react"Filter with wildcards or regex:
# upgrade packages that start with "react-"
ncu react-*
ncu "/^react-.*$/"Exclude specific packages with the --reject option or prefixing a filter with !. Supports strings, wildcards, globs, comma-or-space-delimited lists, and regex:
# upgrade everything except nodemon
ncu \!nodemon
ncu -x nodemon
ncu --reject nodemon
# upgrade packages that do not start with "react-".
ncu \!react-*
ncu '/^(?!react-).*$/' # mac/linux
ncu "/^(?!react-).*$/" # windowsAdvanced filters: filter, filterResults, filterVersion
- Direct dependencies are updated to the latest stable version:
2.0.1→2.2.01.2→1.30.1.0→1.0.1
- Range operators are preserved and the version is updated:
^1.2.0→^2.0.01.x→2.x>0.2.0→>0.3.0
- "Less than" is replaced with a wildcard:
<2.0.0→^3.0.01.0.0 < 2.0.0→^3.0.0
- "Any version" is preserved:
*→*
- Prerelease versions are ignored by default.
- Use
--preto include prerelease versions (e.g.alpha,beta,build1235)
- Use
- Choose what level to upgrade to:
- With
--target semver, update according to your specified semver version ranges:^1.1.0→^1.9.99
- With
--target minor, strictly update the patch and minor versions (including major version zero):0.1.0→0.2.1
- With
--target patch, strictly update the patch version (including major version zero):0.1.0→0.1.2
- With
--target @next, update to the version published on thenexttag:0.1.0->0.1.1-next.1
- With

Some options have advanced usage, or allow per-package values by specifying a function in your .ncurc.js file.
Run ncu --help [OPTION] to view advanced help for a specific option, or see below:
Usage:
ncu --doctor -u
ncu --no-doctor
ncu -du
Iteratively installs upgrades and runs your project's tests to identify breaking upgrades. Reverts broken upgrades and updates package.json with working upgrades.
Requires -u to execute (modifies your package file, lock file, and node_modules)
To be more precise:
- Runs
npm installandnpm testto ensure tests are currently passing. - Runs
ncu -uto optimistically upgrade all dependencies. - If tests pass, hurray!
- If tests fail, restores package file and lock file.
- For each dependency, install upgrade and run tests.
- Prints broken upgrades with test error.
- Saves working upgrades to package.json.
Additional options:
| --doctorInstall | specify a custom install script (default: `npm install` or `yarn`) |
| --doctorTest | specify a custom test script (default: `npm test`) |
Example:
$ ncu --doctor -u

Usage:
ncu --filter [p]
ncu -f [p]
Include only package names matching the given string, wildcard, glob, comma-or-space-delimited list, /regex/, or predicate function. Only included packages will be checked with --peer.
--filter runs before new versions are fetched, in contrast to --filterResults which runs after.
The predicate function is only available in .ncurc.js or when importing npm-check-updates as a module, not on the command line.
/**
@param name The name of the dependency.
@param semver A parsed Semver array of the current version.
(See: https://git.coolaj86.com/coolaj86/semver-utils.js#semverutils-parse-semverstring)

*/
filterFunction: (name, semver) => {
if (name.startsWith('@myorg/')) {
return false
}
return true
}Filters out upgrades based on a user provided function.
filterResults runs after new versions are fetched, in contrast to filter, reject, filterVersion, and rejectVersion, which run before. This allows you to filter out upgrades with filterResults based on how the version has changed (e.g. a major version change).
Only available in .ncurc.js or when importing npm-check-updates as a module.
/** Filter out non-major version updates. Note this could also be achieved with --target semver.
@param {string} packageName The name of the dependency.
@param {string} current Current version declaration (may be a range).
@param {SemVer[]} currentVersionSemver Current version declaration in semantic versioning format (may be a range).
@param {string} upgraded Upgraded version.
@param {SemVer} upgradedVersionSemver Upgraded version in semantic versioning format.
@returns {boolean} Return true if the upgrade should be kept, otherwise it will be ignored.

return currentMajor < upgradedMajor
}
return true
}For the SemVer type definition, see: https://git.coolaj86.com/coolaj86/semver-utils.js#semverutils-parse-semverstring
Usage:
ncu --filterVersion [p]
Include only versions matching the given string, wildcard, glob, comma-or-space-delimited list, /regex/, or predicate function.
--filterVersion runs before new versions are fetched, in contrast to --filterResults which runs after.
The predicate function is only available in .ncurc.js or when importing npm-check-updates as a module, not on the command line. This function is an alias for the filter option function.
/**

return true
}Usage:
ncu --format [value]
Modify the output formatting or show additional information. Specify one or more comma-delimited values.
| group | Groups packages by major, minor, patch, and major version zero updates. |
| ownerChanged | Shows if the package owner has changed. |
| repo | Infers and displays links to the package's source code repository. Requires packages to be installed. |
| time | Shows the publish time of each upgrade. |
| lines | Prints name@version on separate lines. Useful for piping to npm install. |
| installedVersion | Prints the exact current version number instead of a range. |
Customize how packages are divided into groups when using --format group.
Only available in .ncurc.js or when importing npm-check-updates as a module, not on the command line.
/**
@param name The name of the dependency.
@param defaultGroup The predefined group name which will be used by default.
@param currentSpec The current version range in your package.json.
@param upgradedSpec The upgraded version range that will be written to your package.json.
@param upgradedVersion The upgraded version number returned by the registry.
@returns A predefined group name ('major' | 'minor' | 'patch' | 'majorVersionZero' | 'none') or a custom string to create your own group.
*/
groupFunction: (name, defaultGroup, currentSpec, upgradedSpec, upgradedVersion) => {
if (name === 'typescript' && defaultGroup === 'minor') {
return 'major'
}
if (name.startsWith('@myorg/')) {
return 'My Org'
}
return defaultGroup
}Usage:
ncu --install [value]
Default: prompt
Control the auto-install behavior.
| always | Runs your package manager's install command automatically after upgrading. |
| never | Does not install and does not prompt. |
| prompt | Shows a message after upgrading that recommends an install, but does not install. In interactive mode, prompts for install. (default) |
Usage:
ncu --packageManager [s]
ncu -p [s]
Specifies the package manager to use when looking up versions.
| npm | System-installed npm. Default. |
| yarn | System-installed yarn. Automatically used if yarn.lock is present. |
| pnpm | System-installed pnpm. Automatically used if pnpm-lock.yaml is present. |
| bun | System-installed bun. Automatically used if bun.lockb is present. |
Usage:
ncu --peer
ncu --no-peer
Check peer dependencies of installed packages and filter updates to compatible versions.
Example:
The following example demonstrates how --peer works, and how it uses peer dependencies from upgraded modules.
The package ncu-test-peer-update has two versions published:
- 1.0.0 has peer dependency
"ncu-test-return-version": "1.0.x" - 1.1.0 has peer dependency
"ncu-test-return-version": "1.1.x"
Our test app has the following dependencies:
"ncu-test-peer-update": "1.0.0",
"ncu-test-return-version": "1.0.0"
The latest versions of these packages are:
"ncu-test-peer-update": "1.1.0",
"ncu-test-return-version": "2.0.0"
With --peer:
ncu upgrades packages to the highest version that still adheres to the peer dependency constraints:
ncu-test-peer-update 1.0.0 → 1.1.0
ncu-test-return-version 1.0.0 → 1.1.0
Without --peer:
As a comparison: without using the --peer option, ncu will suggest the latest versions, ignoring peer dependencies:
ncu-test-peer-update 1.0.0 → 1.1.0
ncu-test-return-version 1.0.0 → 2.0.0
Usage:
ncu --registryType [type]
Specify whether --registry refers to a full npm registry or a simple JSON file.
| npm | Default npm registry |
| json | Checks versions from a file or url to a simple JSON registry. Must include the `--registry` option.
Example: registry.json: |
Usage:
ncu --reject [p]
ncu -x [p]
The inverse of --filter. Exclude package names matching the given string, wildcard, glob, comma-or-space-delimited list, /regex/, or predicate function. This will also exclude them from the --peer check.
--reject runs before new versions are fetched, in contrast to --filterResults which runs after.
The predicate function is only available in .ncurc.js or when importing npm-check-updates as a module, not on the command line.
/**
@param name The name of the dependency.
@param semver A parsed Semver array of the current version.
(See: https://git.coolaj86.com/coolaj86/semver-utils.js#semverutils-parse-semverstring)
@returns True if the package should be excluded, false if it should be included.
*/
rejectFunction: (name, semver) => {
if (name.startsWith('@myorg/')) {
return true
}
return false
}Usage:
ncu --rejectVersion [p]
The inverse of --filterVersion. Exclude versions matching the given string, wildcard, glob, comma-or-space-delimited list, /regex/, or predicate function.
--rejectVersion runs before new versions are fetched, in contrast to --filterResults which runs after.
The predicate function is only available in .ncurc.js or when importing npm-check-updates as a module, not on the command line. This function is an alias for the reject option function.
/**
@param name The name of the dependency.
@param semver A parsed Semver array of the current version.
(See: https://git.coolaj86.com/coolaj86/semver-utils.js#semverutils-parse-semverstring)
@returns True if the package should be excluded, false if it should be included.
*/
rejectVersionFunction: (name, semver) => {
if (name.startsWith('@myorg/') && parseInt(semver[0]?.major) > 5) {
return true
}
return false
}Usage:
ncu --target [value]
ncu -t [value]
Determines the version to upgrade to. (default: "latest")
| greatest | Upgrade to the highest version number published, regardless of release date or tag. Includes prereleases. |
| latest | Upgrade to whatever the package's "latest" git tag points to. Excludes prereleases unless --pre is specified. |
| minor | Upgrade to the highest minor version without bumping the major version. |
| newest | Upgrade to the version with the most recent publish date, even if there are other version numbers that are higher. Includes prereleases. |
| patch | Upgrade to the highest patch version without bumping the minor or major versions. |
| semver | Upgrade to the highest version within the semver range specified in your package.json. |
| @[tag] | Upgrade to the version published to a specific tag, e.g. 'next' or 'beta'. |
You can also specify a custom function in your .ncurc.js file, or when importing npm-check-updates as a module:
/** Upgrade major version zero to the next minor version, and everything else to latest.
@param name The name of the dependency.
@param semver A parsed Semver object of the upgraded version.
(See: https://git.coolaj86.com/coolaj86/semver-utils.js#semverutils-parse-semverstring)
@returns One of the valid target values (specified in the table above).
*/
target: (name, semver) => {
if (parseInt(semver[0]?.major) === '0') return 'minor'
return 'latest'
}Use a .ncurc.{json,yml,js,cjs} file to specify configuration information.
You can specify the file name and path using --configFileName and --configFilePath
command line options.
For example, .ncurc.json:
{
"upgrade": true,
"filter": "svelte",
"reject": ["@types/estree", "ts-node"]
}If you write .ncurc config files using json or yaml, you can add the JSON Schema to your IDE settings for completions.
e.g. for VS Code:
"json.schemas": [
{
"fileMatch": [
".ncurc",
".ncurc.json",
],
"url": "https://raw.githubusercontent.com/raineorshine/npm-check-updates/main/src/types/RunOptions.json"
}
],
"yaml.schemas": {
"https://raw.githubusercontent.com/raineorshine/npm-check-updates/main/src/types/RunOptions.json": [
".ncurc.yml",
]
},npm-check-updates can be imported as a module:
import ncu from 'npm-check-updates'
const upgraded = await ncu.run({
// Pass any cli option
packageFile: '../package.json',
upgrade: true,
// Defaults:
// jsonUpgraded: true,
// silent: true,
})
console.log(upgraded) // { "mypackage": "^2.0.0", ... }Contributions are happily accepted. I respond to all PR's and can offer guidance on where to make changes. For contributing tips see CONTRIBUTING.md.
