Readme

npm-check-updates

npm version Build Status Dependency Status

Fork which uses the global npm that comes with your node install

Coverage Status

npm-check-updates upgrades your package.json dependencies to the latest versions, ignoring specified versions.

  • maintains existing semantic versioning policies, i.e. "express": "^4.0.0" to "express": "^5.0.0".
  • only modifies package.json file. Run npm install to update your installed packages and package-lock.json.

npm-check-updates-screenshot

  • Red = major upgrade (and all major version zero)
  • Cyan = minor upgrade
  • Green = patch upgrade

You may also want to consider npm-check. Similar purpose, different features.

Installation

npm install -g npm-check-updates

Usage

Show any new dependencies for the project in the current directory:

$ ncu
Checking package.json
[====================] 5/5 100%

 express           4.12.x  →   4.13.x
 multer            ^0.1.8  →   ^1.0.1
 react-bootstrap  ^0.22.6  →  ^0.24.0
 react-a11y        ^0.1.1  →   ^0.2.6
 webpack          ~1.9.10  →  ~1.10.5

Run ncu -u to upgrade 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 -u
Upgrading package.json
[====================] 1/1 100%

 express           4.12.x  →   4.13.x

Run npm install to install new versions.

$ npm install      # update installed packages and package-lock.json

Check global packages:

ncu -g

Filter packages using the --filter option or adding additional cli arguments. You can exclude specific packages with the --reject option or prefixing a filter with !. Supports strings, wildcards, globs, comma-or-space-delimited lists, and regular expressions:

# upgrade only mocha
ncu mocha
ncu -f mocha
ncu --filter mocha

# upgrade packages that start with "react-"
ncu react-*
ncu "/^react-.*$/"

# upgrade everything except nodemon
ncu \!nodemon
ncu -x nodemon
ncu --reject nodemon

# upgrade only chalk, mocha, and react
ncu chalk mocha react
ncu chalk, mocha, react
ncu -f "chalk mocha react"

# upgrade packages that do not start with "react-".
ncu \!react-*
ncu '/^(?!react-).*$/' # mac/linux
ncu "/^(?!react-).*$/" # windows

How dependency updates are determined

  • Direct dependencies are updated to the latest stable version:
    • 2.0.12.2.0
    • 1.21.3
    • 0.1.01.0.1
  • Range operators are preserved and the version is updated:
    • ^1.2.0^2.0.0
    • 1.x2.x
    • >0.2.0>0.3.0
  • "Less than" is replaced with a wildcard:
    • <2.0.0^3.0.0
    • 1.0.0 < 2.0.0^3.0.0
  • "Any version" is preserved:
    • **
  • Prerelease and deprecated versions are ignored by default.
    • Use --pre to include prerelease versions (e.g. alpha, beta, build1235)
    • Use --deprecated to include deprecated versions
  • With --target minor, only update patch and minor:
    • 0.1.00.2.1
  • With --target patch, only update patch:
    • 0.1.00.1.2

Doctor Mode

Usage: ncu --doctor [-u] [options]

Iteratively installs upgrades and runs tests to identify breaking upgrades. Add -u to execute (modifies your package file, lock file, and node_modules).

To be more precise:

  1. Runs npm install and npm test to ensure tests are currently passing.
  2. Runs ncu -u to optimistically upgrade all dependencies.
  3. If tests pass, hurray!
  4. If tests fail, restores package file and lock file.
  5. For each dependency, install upgrade and run tests.
  6. When the breaking upgrade is found, saves partially upgraded package.json (not including the breaking upgrade) and exits.

Example:

$ ncu --doctor -u
npm install
npm run test
ncu -u
npm install
npm run test
Failing tests found:
/projects/myproject/test.js:13
  throw new Error('Test failed!')
  ^
Now let's identify the culprit, shall we?
Restoring package.json
Restoring package-lock.json
npm install
npm install --no-save react@16.0.0
npm run test
  ✓ react 15.0.0 → 16.0.0
npm install --no-save react-redux@7.0.0
npm run test
  ✗ react-redux 6.0.0 → 7.0.0
Saving partially upgraded package.json

Configuration Files

Use a .ncurc.{json,yml,js} file to specify configuration information. You can specify file name and path using --configFileName and --configFilePath command line options.

For example, .ncurc.json:

{
  "upgrade": true,
  "filter": "express",
  "reject": [
    "@types/estree",
    "ts-node"
  ]
}

Module/Programmatic Usage

npm-check-updates can be required as a module:

const ncu = require('npm-check-updates')

(async () => {

  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", ... }

})()

Known Issues

  • Windows: If npm-check-updates hangs, try setting the package file explicitly: ncu --packageFile package.json. You can run ncu --loglevel verbose to confirm that it was incorrectly waiting for stdin. See #136.
