### Synopsis

### Description

The `npm query` command allows for usage of css selectors in order to retrieve
an array of dependency objects.

### Piping npm query to other commands

```bash
# find all dependencies with postinstall scripts & uninstall them
npm query ":attr(scripts, [postinstall])" | jq 'map(.name)|join("\n")' -r | xargs -I {} npm uninstall {}

# find all git dependencies & explain who requires them
npm query ":type(git)" | jq 'map(.name)' | xargs -I {} npm why {}
```

### Extended Use Cases & Queries

```stylus
// all deps
*

// all direct deps
:root > *

// direct production deps
:root > .prod

// direct development deps
:root > .dev

// any peer dep of a direct deps
:root > * > .peer

// any workspace dep
.workspace

// all workspaces that depend on another workspace
.workspace > .workspace

// all workspaces that have peer deps
.workspace:has(.peer)

// any dep named "lodash"
// equivalent to [name="lodash"]
#lodash

// any deps named "lodash" & within semver range ^"1.2.3"
#lodash@^1.2.3
// equivalent to...
[name="lodash"]:semver(^1.2.3)

// get the hoisted node for a given semver range
#lodash@^1.2.3:not(:deduped)

// querying deps with a specific version
#lodash@2.1.5
// equivalent to...
[name="lodash"][version="2.1.5"]

// has any deps
:has(*)

// deps with no other deps (ie. "leaf" nodes)
:empty

// manually querying git dependencies
[repository^=github:],
[repository^=git:],
[repository^=https://github.com],
[repository^=http://github.com],
[repository^=https://github.com],
[repository^=+git:...]

// querying for all git dependencies
:type(git)

// get production dependencies that aren't also dev deps
.prod:not(.dev)

// get dependencies with specific licenses
[license=MIT], [license=ISC]

// find all packages that have @ruyadorno as a contributor
:attr(contributors, [email=ruyadorno@github.com])
```

### Example Response Output

- an array of dependency objects is returned which can contain multiple copies of the same package which may or may not have been linked or deduped

  {
