# npm-outdated

Check for outdated packages

## SYNOPSIS

    npm outdated [[<@scope>/]<pkg> ...]

## DESCRIPTION

This command will check the registry to see if any (or, specific) installed packages are currently outdated.

In the output:

- `wanted` is the maximum version of the package that satisfies the semver range specified in `package.json`. If there's no available semver range (i.e. you're running `npm outdated --global`, or the package isn't included in `package.json`), then `wanted` shows the currently-installed version.
- `latest` is the version of the package tagged as latest in the registry. Running `npm publish` with no special configuration will publish the package with a dist-tag of `latest`. This may or may not be the maximum version of the package, or the most-recently published version of the package, depending on how the package's developer manages the latest dist-tag(1).
- `location` is where in the dependency tree the package is located. Note that `npm outdated` defaults to a depth of 0, so unless you override that, you'll always be seeing only top-level dependencies that are outdated.
- `package type` (when using `--long` / `-l`) tells you whether this package is a `dependency` or a `devDependency`. Packages not included in `package.json` are always marked `dependencies`.
- `homepage` (when using `--long` / `-l`) is the `homepage` value contained in the package's `package.json`
- Red means there's a newer version matching your semver requirements, so you should update now.
- Yellow indicates that there's a newer version above your semver requirements (usually new major, or new 0.x minor) so proceed with caution.

### An example

    $ npm outdated
    Package      Current   Wanted   Latest  Location
    glob          5.0.15   5.0.15    6.0.1  test-outdated-output
    nothingness    0.0.3      git      git  test-outdated-output
    npm            3.5.1    3.5.2    3.5.1  test-outdated-output
    local-dev      0.0.3   linked   linked  test-outdated-output
    once           1.3.2    1.3.3    1.3.3  test-outdated-output

With these `dependencies`:

    {
      "glob": "^5.0.15",
      "nothingness": "github:othiym23/nothingness#master",
      "npm": "^3.5.1",
      "once": "^1.3.1"
    }

A few things to note:

- `glob` requires `^5`, which prevents npm from installing `glob@6`, which is outside the semver range.
- Git dependencies will always be reinstalled, because of how they're specified. The installed committish might satisfy the dependency specifier (if it's something immutable, like a commit SHA), or it might not, so `npm outdated` and `npm update` have to fetch Git repos to check. This is why currently doing a reinstall of a Git dependency always forces a new clone and install.
- `npm@3.5.2` is marked as "wanted", but "latest" is `npm@3.5.1` because npm uses dist-tags to manage its `latest` and `next` release channels. `npm update` will install the newest version, but `npm install npm` (with no semver range) will install whatever's tagged as `latest`.
- `once` is just plain out of date. Reinstalling `node_modules` from scratch or running `npm update` will bring it up to spec.
