title: npm-query | ||
section: 1 | ||
description: Dependency selector query | ||
--- | ||
|
||
### Synopsis | ||
|
||
<!-- AUTOGENERATED USAGE DESCRIPTIONS START --> | ||
<!-- automatically generated, do not edit manually --> | ||
<!-- see lib/commands/query.js --> | ||
|
||
```bash | ||
npm query <selector> | ||
``` | ||
|
||
<!-- automatically generated, do not edit manually --> | ||
<!-- see lib/commands/query.js --> | ||
|
||
<!-- AUTOGENERATED USAGE DESCRIPTIONS END --> | ||
|
||
### 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 | ||
|
||
```json | ||
[ | ||
{ | ||
"name": "", | ||
"version": "", | ||
"description": "", | ||
"homepage": "", | ||
"bugs": {}, | ||
"author": {}, | ||
"license": {}, | ||
"funding": {}, | ||
"files": [], | ||
"main": "", | ||
"browser": "", | ||
"bin": {}, | ||
"man": [], | ||
"directories": {}, | ||
"repository": {}, | ||

``` | ||
|
||
### Configuration | ||
|
||
<!-- AUTOGENERATED CONFIG DESCRIPTIONS START --> | ||
<!-- automatically generated, do not edit manually --> | ||
<!-- see lib/utils/config/definitions.js --> | ||
#### `global` | ||
|
||
* Default: false | ||
* Type: Boolean | ||
|
||
Operates in "global" mode, so that packages are installed into the `prefix` | ||
folder instead of the current working directory. See | ||
[folders](/configuring-npm/folders) for more on the differences in behavior. | ||
|
||
* packages are installed into the `{prefix}/lib/node_modules` folder, instead | ||
of the current working directory. | ||
* bin files are linked to `{prefix}/bin` | ||
* man pages are linked to `{prefix}/share/man` | ||
|
||
<!-- automatically generated, do not edit manually --> | ||
<!-- see lib/utils/config/definitions.js --> | ||
|
||
#### `workspace` | ||
|
||
* Default: | ||
* Type: String (can be set multiple times) | ||
|
||
Enable running a command in the context of the configured workspaces of the | ||
current project while filtering by running only the workspaces defined by | ||
this configuration option. | ||
|
||
Valid values for the `workspace` config are either: | ||
|
||
* Workspace names | ||
* Path to a workspace directory | ||
* Path to a parent workspace directory (will result in selecting all | ||
workspaces within that folder) | ||
|
||
When set for the `npm init` command, this may be set to the folder of a | ||
workspace which does not yet exist, to create the folder and set it up as a | ||
brand new workspace within the project. | ||
|
||
This value is not exported to the environment for child processes. | ||
|
||
<!-- automatically generated, do not edit manually --> | ||
<!-- see lib/utils/config/definitions.js --> | ||
|
||
#### `workspaces` | ||
|
||
* Default: null | ||
* Type: null or Boolean | ||
|
||
Set to true to run the command in the context of **all** configured | ||
workspaces. | ||
|
||
Explicitly setting this to false will cause commands like `install` to | ||
ignore workspaces altogether. When not set explicitly: | ||
|
||
- Commands that operate on the `node_modules` tree (install, update, etc.) | ||
will link workspaces into the `node_modules` folder. - Commands that do | ||
other things (test, exec, publish, etc.) will operate on the root project, | ||
_unless_ one or more workspaces are specified in the `workspace` config. | ||
|
||
This value is not exported to the environment for child processes. | ||
|
||
<!-- automatically generated, do not edit manually --> | ||
<!-- see lib/utils/config/definitions.js --> | ||
|
||
#### `include-workspace-root` | ||
|
||
* Default: false | ||
* Type: Boolean | ||
|
||
Include the workspace root when workspaces are enabled for a command. | ||
|
||
When false, specifying individual workspaces via the `workspace` config, or | ||
all workspaces via the `workspaces` flag, will cause npm to operate only on | ||
the specified workspaces, and not on the root project. | ||
|
||
This value is not exported to the environment for child processes. | ||
|
||
