**npm-check-updates upgrades your package.json dependencies to the _latest_ versions, ignoring specified versions.**
- maintains existing semantic versioning _policies_, i.e. `"react": "^16.0.4"` to `"react": "^18.2.0"`.
- _only_ modifies package.json file. Run `npm install` to update your installed packages and package-lock.json.
- clean output
- sensible defaults
- lots of options for custom behavior
- CLI and module usage
- compatible with `npm`, `yarn`, and `pnpm`

- Red = major upgrade (and all [major version zero](https://semver.org/#spec-item-4))
- Cyan = minor upgrade
- Green = patch upgrade
## Installation
Install globally:
```sh
npm install -g npm-check-updates
```
Or run with [npx](https://docs.npmjs.com/cli/v7/commands/npx):
```sh
npx npm-check-updates
```
## Usage
Show all new dependencies ([excluding peerDependencies](https://github.com/raineorshine/npm-check-updates/issues/951)) for the project in the current directory:
```sh
$ ncu
Checking package.json
[====================] 5/5 100%
eslint 7.32.0 → 8.0.0
prettier ^2.7.1 → ^3.0.0
svelte ^3.48.0 → ^3.51.0
typescript >3.0.0 → >4.0.0
untildify <4.0.0 → ^4.0.0
webpack 4.x → 5.x
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.**
```sh
$ 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:
```sh
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:
```sh
# 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:
- `2.0.1` → `2.2.0`
- `1.2` → `1.3`
- `0.1.0` → `1.0.1`
- Range operators are preserved and the version is updated:
- `^1.2.0` → `^2.0.0`
- `1.x` → `2.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:
- `0.1.0` → `0.2.1`
- With `--target patch`, only update patch:
- `0.1.0` → `0.1.2`
- With `--target @next`, update to the version published on the `next` tag:
- `0.1.0` -> `0.1.1-next.1`
## Options
Options are merged with the following precedence:
1. CLI
2. Local [Config File](#config-file)
3. Project Config File
4. User Config File
Options that take no arguments can be negated by prefixing them with `--no-`, e.g. `--no-peer`.

## Advanced Options
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:
## doctor
Usage:
ncu --doctor
ncu --no-doctor
ncu -d
Iteratively installs upgrades and runs tests to identify breaking upgrades. Reverts broken upgrades and updates package.json with working 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. Prints broken upgrades with test error.
7. Saves working upgrades to package.json.
