Find newer versions of dependencies than what your package.json or bower.json allows
npm-check-updates is a command-line tool that allows you to upgrade your package.json or bower.json dependencies to the latest versions, regardless of existing version constraints.
npm-check-updates maintains your existing semantic versioning policies, i.e., it will upgrade your
"express": "^4.11.2" dependency to
"express": "^5.0.0" when express 5.0.0 is released.
npm install -g npm-check-updates
Show any new dependencies for the project in the current directory:
$ ncuexpress 4.12.x → 4.13.xmulter ^0.1.8 → ^1.0.1react-bootstrap ^0.22.6 → ^0.24.0react-a11y ^0.1.1 → ^0.2.6webpack ~1.9.10 → ~1.10.5Run with -u to upgrade your package.json
Upgrade a project's package file:
Make sure your package file is in version control and all changes have been committed. This will overwrite your package file.
$ ncu -uexpress 4.12.x → 4.13.xpackage.json upgraded
Include or exclude specific packages:
# match mocha and should packages exactly$ ncu mocha,should# match packages that start with "gulp-" using regex$ ncu /^gulp-/# match packages that do not start with "gulp-". Note: single quotes are required# here to avoid inadvertant bash parsing$ ncu '/^(?!gulp-).*$/'
-d, --dev check only devDependencies -e, --error-level set the error-level. 1: exits with error code 0 if no errors occur. 2: exits with error code 0 if no packages need updating (useful for continuous integration) -g, --global check global packages instead of in the current project -h, --help output usage information -j, --jsonAll output new package file instead of human-readable message --jsonUpgraded output upgraded dependencies in json --packageData include stringified package file (use stdin instead) --packageFile package file location (default: ./package.json) -m, --packageManager npm or bower (default: npm) -o, --optional check only optionalDependencies -p, --prod check only dependencies (not devDependencies) -r, --registry specify third-party NPM registry -s, --silent don't output anything -t, --greatest find the highest versions available instead of the latest stable versions (alpha release only) -u, --upgrade overwrite package file -a, --upgradeAll include even those dependencies whose latest version satisfies the declared semver dependency -V, --version output the version number
The tool allows integration with 3rd party code:
var ncu = require'npm-check-updates';ncurunpackageFile: 'package.json'// Any command-line option can be specified here.// These are set by default:// silent: true,// jsonUpgraded: truethenconsole.log'dependencies to upgrade:' upgraded;;
1.0.0 < 2.0.0→
^1.0.0 is a range that will includes all non-major updates. If you run
npm update, it will install
1.0.1 without changing the dependency listed in your package file. You don't need to update your package file if the latest version is satisfied by the specified dependency range. If you really want to upgrade your package file (even though it's not necessary), you can run
See the github releases.
For help migrating from v1 to v2, see the v2 release notes.
ncu --packageFile package.json.
When filing an issue, always include the dependencies from your package file (or the output from
npm -g ls --depth=0 if using global mode)!
