npm-outdated(1) -- Check for outdated packages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npm outdated [[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packages are currently outdated.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you're running `npm outdated --global`, or the package isn't included in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`npm outdated` defaults to a depth of 0, so unless you override that, you'll
always be seeing only top-level dependencies that are outdated.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`.
### 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$ npm outdated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glob 5.0.15 5.0.15 6.0.1 test-outdated-output
nothingness 0.0.3 git git test-outdated-output
npm 3.5.1 3.5.2 3.5.1 test-outdated-output
local-dev 0.0.3 linked linked test-outdated-output
once 1.3.2 1.3.3 1.3.3 test-outdated-output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`:
```json
{
"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something immutable, like a commit SHA), or it might not, so `npm outdated` and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.
